POWER BUTTON SAMPLE RATE

Press for power on. Press again for power off.
Selects the sample rate (sampling frequency) for the digital outputs and word clock output to either 44.1 kHz or 48 kHz (the upper two LEDs are unused). The Rosetta 96 also includes 88.2 kHz and 96 kHz selections and uses the upper two LEDs.
Select 44.1 kHz to record to Compact Disc (CD-R). Some consumer DAT recorders can only record at 48 kHz. The default sample rate for recording on the original Alesis ADAT (black face) is 48 kHz. Please consult the respective equipment manuals for any limitations on sample rate selections.
Most recording devices will automatically lock to the incoming sample rate when digital input is selected. If your device does not automatically do so, manually select the same sampling rate for both the Rosetta and the recording device and/or configure the receiving device to clock from its digital input. Recording equipment will only accept 88.2 and 96 kHz sampling rates if equipped to do so. 88.2 and 96 kHz signals are supplied using the two industry-accepted methods. In double-wire (also called double-wide) mode, the high resolution signals are supplied via the Rosettas AES outputs the left channel via AES 1 output and the right channel via AES 2 output. To configure the Rosetta for double-wire mode, place DIP switch 6 in the UP position. The other transmission method for 88.2 and 96 kHz signals is the single-wire (sometimes called double-fast) method. This method uses only one AES (or S/PDIF) output for transmission of both the left and right channels, similar to the AES3 standard widely used for normal 44.1 and 48 kHz signals. To configure the Rosetta for single-wire mode, make sure that DIP switch 6 is in the DOWN position. Check your recording device to see whether it uses the double-wire or single-wire mode. While the Rosetta is set to 88.2 or 96 kHz sampling rates and the unit is configured for double-wire operation, the S/PDIF coaxial and optical outputs will output every other sample. So, for example, if the Rosetta is set to 96 kHz, the S/PDIF outputs will output 48 kHz audio. Keep in mind that this audio has not been converted from analog using the proper filters for 44.1/48 kHz sampling rates. Therefore, the audio output from the S/PDIF outputs while in double-wire 88.2/96 kHz mode may have aliasing components and therefore should be used as a quick reference only. We recommend that you do not use the S/PDIF outputs as the main output feed while in 88.2/96 kHz mode. While the Rosetta is in 88.2/96 kHz sampling rate and the unit is configured for single-wire operation, the S/PDIF coaxial and optical outputs will deliver single-wire 88.2/96 kHz.

RESOLUTION

Selects the word length (also referred to as bit rate or resolution) for the digital output. Note that the Rosetta always converts analog to digital at 24-bit resolution. To output a 16-bit or 20-bit signal, the UV22HR process can be applied by selecting 16-bit UV22 or 20-bit UV22 respectively.

Page 12

Rosetta AD Users Guide If you need to record on to a 16-bit or 20-bit device without UV22HR, select 24-bit. The recording device will truncate (i.e., not use) the least significant bits (LSBs). See the section on UV22HR for more information. If the recorded audio is going to be de-tuned (pitched-down) by more than a major third, data-compressed by a lossy compression system or normalized, be aware of (and listen carefully for) artifacts that can occur as a result of mixing these processes. Ideally, UV22HR should be the final process applied to the digital signal. NOTE: UV22HR cannot be applied to 88.2 and 96 kHz signals. In virtually all cases, stereo recording systems capable of operation at 88.2 or 96 kHz will also be capable of 24-bit operation. The software of the Rosetta 96 prevents you from selecting any of the UV22HR settings when sampling at 88.2 kHz and 96 kHz. If you try to select any of the UV22HR settings while operating at these sample rates, an error will be indicated by the 88.2 or 96 LED flashing. Also, if you are operating at a lower sample rate and using either of the UV22HR settings, the resolution will automatically switch to 24-BIT as soon as you switch to a higher sampling rate (88.2 or 96 kHz).

OPTICAL OUT

Selects which of the two formats, S/PDIF Optical (TOSLink) or ADAT, will be provided via the optical output on the rear panel. Set to ADAT when recording to a device with an ADAT format optical input (if using an ADAT XT, be sure to set the ADAT to DIG clock). Set to S/PDIF when recording to a device that accepts the S/PDIF format (these devices include many DAT recorders, CD recorders, consumer electronics recorders, etc). NOTE: The recording systems manual will indicate whether it accepts ADAT format or S/PDIF Optical (TOSLink) input. There are differences in the two formats as follows: S/PDIF format is output as simply two channels: left and right. ADAT format is output as L/R channels repeated across the eight ADAT channels. So, ADAT channel 1 will receive the left channel; ADAT channel 2 will receive the right channel; ADAT channel 3 will receive the left channel; ADAT channel 4 will receive the right channel and so on. Simply record-arm the tracks on which you wish to record. ADAT CHANNELS 1 ROSETTA CHANNELS L 2 R 3 L 4 R 5 L 6 R 7 L 8 R

L/R LEVEL TRIM

Adjusts the level sensitivity of the A/D section. As discussed in the METERS description, digital and analog scales are different. The level trim pots allow you to set the Rosetta to an operating level that is convenient for your particular application. See page 18 for proper level adjustment of your Rosetta. Because of the unpredictable dynamic range of live performance, its often desirable to have plenty of headroom to capture a performance without risking overs. In this case, you may want to set the Rosetta to 20 or 18dBFS. The SOFT LIMIT function will also prove to be a useful feature in live recording. Levels are usually more controlled during a mix. In this case, the Rosetta can be adjusted to 16 to 12 dBFS to lay down the final mix.

Tracking

Mixing

Mastering

In the mastering stage, its often desirable to get the hottest signal on to tape. Hot transients are usually better-controlled at this stage. The converter does not need as much headroom, so it can be set to 12dBFS. The chart on the next page shows the relationship between dBu and dBFS for the purposes of setting the levels on the Rosetta.

Page 14

The Rear Panel

AD INPUT

Left and Right Analog inputs. The Rosetta is configured from the factory for pin 2 hot operation. To change to pin 3 hot, set DIP switch #2 to the ON position. Note: The Rosetta does not contain microphone preamplifiers, so a microphone cannot be connected directly to the AD inputs. Also, to accommodate the very high impedance outputs of guitars/basses, use a suitable preamplifier (or a direct box) in between the Rosetta and your guitar/bass. All of the Rosettas outputs are always active. Several different format recorders can be connected to the Rosetta and all will simultaneously receive the same audio. TDIF Tascam Digital Interface Format for use with Tascams DA-88/38/98/78 and other devices equipped with the TDIF format. Make sure to use a Tascam-approved TDIF cable (such as the Tascam PW-88-S) a 25-pin computer cable will not work because the TDIF pin configuration is different than that of point-to-point computer cables. Using a non-authorized cable may damage the Rosetta and DA-88/38/98/78. NOTE: If you have the Rosetta 96 and an ADAT or TDIF recorder, be sure to read Recording High Density Signals with your MDM on Page 17. AES 1/2 The industry standard AES/EBU (Audio Engineering Society/European Broadcast Union) format. In 44.1/48 kHz sampling modes, the Rosetta outputs the same AES/EBU signal from both AES outputs. This is convenient for making backup recordings to DAT during mixing, for example. Simply connect the AES output of the Rosetta to the AES/EBU input of the receiving device. Audio data and sync are carried in the same cable. Set the receiving device to digital in. If the receiving device does not automatically switch its sync source to digital in, manually select the AES/EBU input as its sync source. NOTE: Be sure to use a quality digital cable for your interconnects. A standard microphone cable is not of high enough bandwidth to carry digital signals reliably. For best sonic results, use a 110 cable created especially for digital audio such as Apogees WydeEye AD 110 ohm (part # WE-XX).

DIGITAL OUTPUTS

Page 15
Rosetta AD Users Guide When configured for double-wire 88.2/96 kHz operation (see page 12 for more information) and 88.2 or 96 kHz is selected as the sampling frequency, the Rosetta 96 outputs the left channel on AES output 1 and the right channel on AES output 2. In this case, please be sure that the device being fed an 88.2 or 96 kHz signal from the Rosetta uses the double-wire method. If the receiving device uses the single-wire (also called double-fast) method (both channels from one output at twice the speed), configure the Rosetta for single-wire 88.2/96 kHz operation (see page 12). S/PDIF Sony/Philips Digital Interface Format. S/PDIF is a popular digital interface format found on virtually all DAT recorders and many pro and semi-pro pieces of equipment. Simply connect the S/PDIF output of the Rosetta to the S/PDIF input of the receiving device. Audio data and sync will be carried in the same cable. Set the receiving device to digital in. If the receiving device does not automatically switch its sync source to digital in, manually select the S/PDIF input as its sync source. For best sonic results, use a 75 coaxial cable created especially for digital audio such as Apogees WydeEye AD 75 (part # WE-RR). SPDIF/ADAT [Optical Output] Outputs either ADAT Optical format or S/PDIF Optical (TOSLink) format according to the selection on the front panel. See front panel description. When configured for double-wire 88.2/96 kHz operation (see page 12 for more information) and 88.2 or 96 kHz is selected as the sampling frequency, the S/PDIF output of the Rosetta 96 outputs every other sample. This signal can be recorded to a normal DAT recorder, for example, or can be used as a quick reference output. However, it is not recommended that this signal be used as your main output signal (see page 12 for important precautions). When configured for single-wire 88.2/96 kHz operation and 88.2 or 96 kHz is selected as the sampling frequency, the S/PDIF output of the Rosetta 96 outputs a full 88.2 or 96 kHz signal. Be sure that the receiving device can accept a full high-density S/PDIF signal.

WC OUT

Word Clock output. Word Clock is used to synchronize a number of digital devices together. To use the Word Clock output, connect a high-quality 75 ohm cable from the WC OUT of the Rosetta to the Word Clock input of the receiving device. Set the receiving device to sync from its Word Clock input. The Word Clock output of the Rosetta is a really clean clock that can be used to synchronize your entire studio (at least all the devices with a WC input). A word clock signal can be chained through successive devices using BNC T splitters on the WC input of each device, with a 75 ohm terminator applied to the last device in the chain.

A major challenge when you want to use high sample rates is, simply, What can I record it on? There are still not too many 88.2/96 kHz sample rate recorders, and even fewer affordable ones. Luckily, with the Rosetta 96, you can use the eight tracks of your existing 16-bit, 44.1/48 kHz sampling modular digital multitrack (MDM) to record two channels of 24-bit, 88.2 or 96 kHz sampling. We call this technique ABS 96 Apogee Bit Splitting for 88.2 and 96kHz sampling. ABS 96 is engaged automatically on the ADAT Optical and TDIF interfaces when the Rosetta 96 is set to 88.2 or 96 kHz sample rates. To record with ABS 96, simply select the desired sample rate on the Rosetta (88.2 or 96 kHz). Insure that your MDM is locked to the external digital clock. If you are using the TDIF interface, connect a Word Clock cable from the Rosetta to Word Sync In and note the setting of DIP Switch 5 (see p16). Remember to record on all eight tracks of the MDM to capture a two channel, high density signal. While the Rosetta 96 includes the capability of recording an ABS 96 signal, it is an A/D only, and as a result has no means of decoding the ABS 96 tracks and re-assembling them into a stereo 24/96 stream. To do this, you will need an Apogee D/A converter such as that in the Apogee PSX-100. Of course, if you are mastering with the Rosetta 96, you can inform your mastering house that you are using ABS 96 and they can employ their own Apogee unit to recover the stereo data.

Internal Adjustments
The following information is provided for authorized technicians only and is not intended for use by the user. Adjustment of internal settings by non-authorized personnel will void the warranty. Technicians are expected to follow appropriate ESD practices.

The Voltage selector

This is located inside the Rosetta, adjacent to the AC connector. The two settings are as follows: 115VAC accepts 95 to 145 V ac (USA and Japan). 230VAC accepts 200 to 250 V ac (most of Europe). 50 or 60 Hertz supplies may be used in either case. The correct setting should already be selected for your area so, unless otherwise indicated, this should not be changed.
The AC fuses are also inside the Rosetta, next to the voltage selector. If the Rosetta does not power up for some reason, check that all AC lines are connected, check that there is power coming from the wall (by connecting another device), and then check the internal fuses. CAUTION For protection against risk of fire, replace only with same type and rating of fuse: 115V~ operation: 250V, 250mA, T (Slow Blow); 230V~ operation: 250V, 125mA, T (Slow Blow) DO NOT LIFT THE GROUND PIN. When tracing down hums and buzzes, the AC ground pin is often lifted to break ground loops. Apogee does not recommend that you lift the ground pin on the Rosetta as AC spikes (that have no path to ground) can severely damage the unit.

Soft Limit Adjustment

1. 2. 3. 4. 5. 6. 7. 8. 9. Make sure that your converter is properly aligned as discussed below. Generate a 1 kHz tone using a function generator or oscillator from your console or test equipment. Increase the output level of the oscillator until the OVER LEDs illuminate. Slowly reduce the output level of the oscillator while repeatedly tapping the METER CLEAR button until the OVER LEDs JUST go off. Note the output level of the oscillator. Select the amount of headroom you wish to achieve using the Soft Limit circuit. The Soft Limit comes calibrated from Apogee at +4dB headroom, so we will use this number as an example. Increase the output level of the oscillator by 4 dB. The OVER LEDs should illuminate again. Turn Soft Limit on. Adjust the Soft Limit trimpots (VR12 for left, VR15 for right) on the AD Module inside the unit while repeatedly tapping the Meter Clear button until the OVER LEDs JUST go off. You have just adjusted Soft Limit for +4 dB of additional headroom. You can change the amount of headroom by changing the output level of the oscillator in step 6.

Rosetta Level Adjustment

Here is a quick guide to adjusting the level sensitivity of the Rosetta. 1. Press and hold the Soft Limit button for two seconds. The Rosetta will enter Calibration Mode indicated by the Soft Limit LED flashing slowly. 2. Now the 12-segment bar graphs will have a range of 21dBFS (leftmost LED) to 10dBFS (rightmost LED) ie, one dB per LED, rather than the value indicated by the labeling. In CAL mode, the OVER LED will illuminate when the signal level is within 0.1 dB of the level indicated by the appropriate meter segment. 3. Generate a 1kHz, +4dBu / 0VU tone using a function generator or oscillator from your console or test equipment and insert it into the analog input jacks. 4. Increase/decrease the analog input level with the Level Trim pots using a tweaker or small screwdriver. 5. As you increase/decrease gain you will notice the OVER LEDs going on and off indicating you were at, and then passed, one of the standard calibration points within 0.1 dB.

Page 18

Rosetta AD Users Guide Example: You wish to align your Rosetta such that a +4dBu / 0VU input equals a digital level of 16dBFS. Reading the 12-segment bar graphs in Cal Mode tells us that 16dBFS equals the sixth bar from the left. Adjust the Level Trim pots. As soon as the sixth bar illuminates, turn slowly until the OVER LED illuminates. You are now calibrated to 16dBFS 0.1 dB. If the OVER LED came on and then went off, you have passed the 0.1 dB threshold; turn SLOWLY in the opposite direction until the OVER LED comes on. Press and hold SOFT LIMIT for two seconds to exit CAL mode. The Soft Limit LED will stop flashing.

About UV22HR Super CD Encoding
Squeezing more performance from a digital recording is not a new idea. It began with adding white noise, called dither, to the digital audio. Plain dither was followed by different flavors of dither noise, then a process called noise shaping, and various forms of so-called bit mapping. Systems have been introduced that store control information in the least-significant bits and use a special decoder to recover the data on playback. Independent listening tests confirm that these systems either color the recordings we are trying to preserve, or compromise the audible noise floor. Encode/decode systems may sound good if they are decoded, but almost nobody owns a decoder! Apogee UV22HR Encoding the latest and most powerful development of Apogees original UV22 process is an entirely different approach. UV22HR does its job without sonic compromise, and without adding a sound of its own, preserving the sound stage and tonal balance of the original high-resolution source. The effects are even audible on original 16-bit recordings. UV22HR Encoding adds an inaudible, algorithmically-generated concentration of energy around 22 kHz. Much as the bias on an analog tape recorder smooths out magnetic tape recording non-linearities, UV22HR silently captures resolution beyond 20-bits on a standard, 16-bit CD. In addition, this inaudible carrier smooths the rough edges of even the most inexpensive CD player or external converter. UV22HR makes your recordings sound better on all listening systems. Running already-mastered 16-bit sources through a UV22HR processor delivers sonic improvements that any user can realize on equipment they already own. UV22HR is a very special information carrier: it is not a new flavor of dither noise. The truly unique statistical properties of UV22HR guarantee a constant white noise floor, very similar in character to analog tape noise, no matter what the input source. If you listen to a UV22HR encoded recording, you can hear a stable, accurate sound stage and faithful tonal balance more than 24dB into the noise just as you do on analog tape. Yet the UV22HRs low audible noise floor sits at the theoretical limit for a 16-bit system. Nothing is lost but a great deal is gained. In listening test after listening test, engineers and reviewers alike choose UV22 over all other systems. Many thousands of CD titles have already been mastered using Apogee UV1000 Super CD Encoders, the AD-1000, and the industry-standard AD-8000 and PSX-100. Apogees UV22 is today in use in the vast majority of US mastering houses, and it is estimated that as many as 80% of the hit records mastered in the United States today utilize UV22.

UV22HR Encoding is best applied as the final step in the signal chain before the actual mastering device. For example, if you are mastering a conventional 16-bit CD, but you have the ability to employ higher-resolution devices earlier in the chain, you should keep your signal at the highest resolution possible until the creation of the final master tape, and at that point apply UV22HR to reduce the word-length from high-resolution to the final 16-bit for Compact Disc. If you are recording at high density (long word-lengths, and 88.2/96 kHz or higher sample rates) and need to generate a 44.1 kHz 16-bit CD master or a 48 kHz 20-bit DVD-Video master, first handle the sample rate conversion at the maximum word length available; then use UV22HR to reduce the word-length when you have a 44.1/48 kHz signal. Sample-rate conversion is a tricky business at best, and you need the maximum resolution available when you do it. This is why we do not provide UV22HR at high sample rates. Because of the addition of the UV22HR signal, we do not recommend that you use the UV22HR process more than once or twice on a signal. Multiple passes through the UV22HR process could degrade the noise floor of the system at the upper frequencies and produce artifacts. Recordings to be used in a sample or sound effects disc can be UV22HR encoded if pitch shifting is not likely to be employed, or if pitch shifting upward only is to be used. Pitch shifting downward on processed signals risks making the normally ultrasonic UV22HR energy concentration audible.

Page 19

Rosetta AD Users Guide You can use UV22HR in conjunction with a wide range of both lossy and lossless compression technologies used in DVD mastering, such as Dolby AC-3, DTS, and MLP (Meridian Lossless Packing). In addition, UV22HR is a very useful technique when used in conjunction with Internet audio delivery systems such as MP3 (MPEG1 Layer III), Real Audio, QuickTime and other systems, where the ability of UV22HR to maintain high-resolution quality and detail at the 16-bit level means smaller, better-sounding files and streaming audio signals, offering more effective use of available bandwidth.

Application Notes

Despite the apparent proliferation of 96 kHz devices, and the apparent demand for them from end-users, it is only recently that standards have been agreed for high density (ie 24 or more bit, 88.2 kHz, 96 kHz and above) conversion. Nowhere is this more true than in the world of digital interconnection. You can either use a single AES interface at double-speed (we call this single-wireor double-fast mode), or a pair of interfaces at normal speed (we refer to this as double-wire or double-wide). Both have advantages and disadvantages, and as a result their adoption in the industry is about 50/50. However it is worth noting that few, if any, digital cables are able to carry double-fast signals any great distance. In most cases, the usable length of a digital cable is reduced by a factor of four. In addition, some AES/EBU routers may not support double fast operation. Apogee supplies both the single-wire and double-wire formats in the Rosetta 96. The formats are selectable via DIP switch #n on the back panel (see page 20). At present, we do not support the use of UV22HR at high sample rates. The reason is simple: it is almost completely unnecessary. (If youre using the one machine we have ever heard of that records at 16-bit, 96 kHz, then Im afraid we cant help you.) In most cases you will want to use shorter word-lengths in conjunction with lower sample rates perhaps youll record at 24/88.2, but you want to get a CD master at the end of the day. Or you are recording at 24/96 for a 20-bit, 48 kHz DVD-Video release. Do your sample rate conversion first. The longer you maintain the maximum word-length, the better it will sound. Apply UV22HR to the 24-bit signal at the final sample rate. We are aware of the fact that the DVD-Audio specification allows for different sample rates in the same family (44.1/88.2/176.4 kHz or 48/96/192 kHz) for different surround channels say 96 kHz for the front and 48 kHz for the rear and that in theory you can use different word lengths as well or instead, including 88.2 and 96 kHz at 16 or 20 bits. However, the general view at present is that longer word lengths are worth maintaining, even more than high sample rates. We are keeping a careful eye on developments in these areas and will review our design criteria in the light of industry requirements and developments.

Getting Started Quickly

CONNECTING POWER
The Rosetta 800 accepts an AC input of 100 to 240v AC at a frequency of 50 to 60 Hz. Thus, the unit may be connected to virtually any AC power outlet found worldwide without concern for voltage settings or fuse ratings.
To reset the Rosetta 800, power up the unit while pressing the SAMPLE RATE button. This provides a quick method to return to factory default settings when exploring the units functionality and capabilities.

USING THIS MANUAL While the regularly scheduled manual runs in the adjacent text, in-depth explanations, operational warnings and other digressions will be presented in these columns. In this manual, parameters are dened as the characteristics of operation, such as SAMPLE RATE or SYNC source, and are capitalized in this manner : SAMPLE RATE. Values are dened as the choices available for each parameter for example, the parameter SAMPLE RATE has the values 44.1, 48, and 96. Values are italicized in this manner: 44.1 Settings are dened as the entire set of parameters and values. SYMBOLS: The exclamation mark alerts the user to potential pitfalls of operation. The musical note indicates indepth explanations.

QUICKSTART

To get started using the Rosetta 800 quickly, please follow these steps: 1) 2) 3) Connect the AC input, and press the POWER button. Connect an analog source to the ANALOG INs, connect a digital device to the appropriate digital I/O (ADAT is used in this example), and connect the ANALOG OUTs to a monitoring system. Set SAMPLE RATE to 44.1, set SOURCE TO DIGITAL OUTS to ANALOG, and set SOURCE TO ANALOG OUTS to ADAT, as shown above.

SIGNAL FLOW

The Rosetta 800 offers the possibility to congure two independent signal paths through the unit. In most cases, the rst signal path is congured as an A/D stage before a digital recording device while the second signal path is congured as a D/A stage after the recording device. For example, when the Rosetta 800 is congured to the Quickstart setting noted above, the following two signal paths are present: 1) the analog sources to be recorded are connected to the Rosetta analog inputs, converted to digital and routed to all Rosetta digital outputs including the ADAT output, connected to an ADAT recording device input; 2) the ADAT device output is connected to the Rosetta ADAT input, which is converted to analog and routed to the Rosetta analog outputs, connected to a monitoring system. Other conguration examples are given in the back of this manual.
Navigating the Front Panel
1) The Power Switch LED indcates that the Rosetta 800 is receiving a proper AC input, and is in Standby mode. The LED goes out when the Rosetta 800 is powered on.
Advanced Settings: Advanced settings are accessed by pressing and holding one front panel button while using a second button to modify values. These advanced settings are described in light gray boxes after the primary description of each button.

2) The 176.4 and 192 values cannot be selected on the 96kHz version of the Rosetta 800. The unit may be upgraded to 192kHz operation at any time.
3) A different AES format may be selected for each sample rate range.
1)POWER SWITCH The Power Switch may be congured to operate in the manner best suited to the installation of the unit. For example, if the Rosetta 800 is installed in a rack with a Master power switch, the units power switch may be congured appropriately. Please see the section of this manual entitled Internal Adjustments for details. 1 2) SAMPLE RATE This parameter modies operation in two distinct ways according to the value selected: 1) When any of the values 44.1-192 are selected, the unit derives its clock from an internal crystal and runs at the selected sample rate. 2 2) When EXT is selected, the unit derives its clock from the source selected by the SYNC parameter; the 44.1-192 LEDs now display the sample rate of the selected source.
4) When clocking to an AES input (i.e SYNC is set to AES), the format must be specied by selecting a SYNC value of either AES or AES + DW.
4 SAMPLE RATE Advanced settings: 3 When running at a sample rate between 88.2-192 kHz, the Rosetta 800s AES I/O may be congured for Single wire or Double wire operation. 1) Select the desired SAMPLE RATE value. 2) Press and hold SAMPLE RATE to determine the current AES format, as indicated by the three DW LEDs on the front panel; if DW is on, the AES format is Double wire; if DW is off, the format is Single wire. 3) While pressing the SAMPLE RATE button, press the SYNC button to toggle DW (Double Wire) on or off.
Navigating the Front Panel -

continued

3) SYNC When SAMPLE RATE is set to EXT, the SYNC parameter determines the source of the units clock. ADAT clock is derived from the ADAT input 1-8 with a resultant sample rate in the 44.1-48kHz range. ADAT + S/MUX clock is derived from S/MUX Input 1-4 with a resultant sample rate in the 88.2-96kHz range. OPTION clock is derived from the Option Card input. 5 AES the AES input is scanned and clock is derived from the rst valid AES signal found. The signal is treated as Single wire format. 6 AES + DW - the AES input is scanned and clock is derived from the rst valid AES signal found. The signal is treated as Double wire format. WC clock is derived from the Word Clock In connector.

5) If no Option card is present, the Option value may not be selected.
6) When clocking to an AES input, the AES format must be specied by selecting a SYNC value of either AES or AES + DW, not via the SAMPLE RATE Advanced settings.
7) The Word Clock Out will always be the same frequency as the Word Clock In.
8 SYNC Advanced settings: 7 The Rosetta 800 may be congured to accommodate digital systems whose word clock signals run at a multiple of the sample rate frequency.
1) To congure the Rosetta 800 to sync to a word clock input of one frequency while running at a sample rate whose frequency is a multiple of the word clock: 1) 2) 3) Connect the word clock signal to the Word Clock In and set SYNC to WC. Press and hold the SYNC button to determine the current target sample rate range. While pressing the SYNC button, press the SAMPLE RATE button to toggle through the possible target ranges. For example, to sync the Rosetta 800 to a 44.1kHz Word Clock input while running at 88.2kHz, maintain the SYNC button depressed while pressing the SAMPLE RATE button the until both the 88.2 and 96 LEDs light.
8) A different Word Clock conguration may be set for each sample rate range.
2) To congure the Rosetta 800 to sync to another source (internally or other SYNC values besides WC) and output a Word Clock signal whose frequency is a multiple of the sample rate frequency: 1) Set the unit to the desired clock source and sample rate 2) Press and hold the SYNC button to determine the current Word Clock Output frequency range. 3) While pressing the SYNC button, press the SAMPLE RATE button to toggle through the possible ranges. For example, to run the Rosetta 800 at an 88.2kHz sample rate while outputting a 44.1kHz word clock, set the SAMPLE RATE to 88.2, maintain the SYNC button depressed while pressing the SAMPLE RATE button until both 44.1 and 48 LEDs light.
9) The clock circuitry of a typical D-to-A converter must be designed as a compromise between the ability to attenuate input signal jitter and the ability to accept any bitstream, regardless of its stability. The more the clock is allowed to track timing variations of the input, the more jitter remains in the clock at the conversion stage, with the degradation of conversion quality as a result. The ROSETTA 800s Dual Stage Clock overcomes this compromise by employing one clock stage to accept the bitstream and store bits in a buffer, and a second stage to clock bits out of the buffer to the conversion stage. The rst stage is optimized to track timing variations of the input, while the second stage is optimized to attenuate jitter and ensure that conversion takes place with the lowest jitter clock possible. 10) When the Rosetta 800 is running at the 176.kHz sample rate range, neither ADAT nor ADAT + S/MUX may be selected.

4) LOCK - These LEDs indicate the Lock status of the Rosetta 800s dual stage clock. Two levels of lock precision are displayed, Wide and Narrow. 9 5) SOURCE TO DIGITAL OUTS This parameter congures the rst of two available signal paths by selecting the input source(s) routed to ALL digital outputs. A total of eight channels may be routed, either entirely from one source or from one digital source and the Analog source. To select a digital source and the Analog source simultaneously, toggle through the entire set of possible values until both desired SOURCE TO DIGITAL OUTS values are lit. Assignment of each of the 8 channels to a digital or analog source is accomplished (by pairs) with the Advanced settings noted below: 12
SOURCE TO DIGITAL OUTS Advanced settings: When two sources have been selected, the following Advanced settings become available: To display current routing: 1) Press and hold the SOURCE TO DIGITAL OUTS button to display the current conguration of analog and digital sources as indicated by the DIGITAL OUT LEDs. If the DIGITAL OUT LED is on, the source for the corresponding channel pair is the Analog input; if the DIGITAL OUT LED is off, the source is the selected digital input. For example, in FIGURE 1, channels 1-2 and 7-8 are set to the Analog source, while channels 3-4 and 5-6 are set to the ADAT source.

FIGURE 1

To modify routing: 1) While pressing the SOURCE TO DIGITAL OUTS button, press the SOFT LIMIT button to select the pair of channels to be modied; the selected pair is indicated by the ashing A/D OVER LEDs. 2) While pressing the SOURCE TO DIGITAL OUTS button, press the OUTPUT RESOLUTION button to toggle the selected pair between ANALOG and the selected digital source.
6) SOFT LIMIT This button engages Soft Limit, Apogees proprietary transient limiting circuitry, on all 8 Analog inputs. Soft Limit transparently rounds transient spikes in a manner similar to analog tape, allowing several more dB of signal to be recorded onto the digital medium. 7) OUTPUT RESOLUTION This button engages UV22HR, Apogees proprietary bit-resolution reduction algorithm, on all digital outputs. UV22HR should be applied when 16-bit digital devices are connected to the Rosetta 800s Digital outputs, such as DAT recorders or CD burners. By adding an algorithmically generated, inaudible concentration of energy at around 22kHz, UV22HR preserves 24-bit resolution in a 16-bit digital signal. 13 8) SIGNAL LEDs 1) A/D OVER These red LEDs indicate the occurrence of digital OVERs (dened as 3 consecutive samples at full scale) in the A/D converter section. 2) DIGITAL OUT These LEDs indicate the digital level of the source(s) routed to the digital outputs. 3) ANALOG OUT These LEDs indicate the digital level of the source(s) routed to the analog outputs. 9) SOURCE TO ANALOG OUT This parameter congures the second available signal path by selecting the input source(s) routed to the analog outputs. A total of eight channels may be routed, either entirely from one source or from one digital source and the analog source. To select a digital source and the Analog source simultaneously, toggle through the entire set of possible values until both desired SOURCE TO ANALOG OUT values are lit. Assignment of each of the 8 channels to a digital or analog source is accomplished (by pairs) with the Advanced settings listed below:

11) A blinking digital source LED indicates that the selected source is not synchronous with the units clock source.
12) The S/MUX and DW LEDs located in the SOURCE TO DIGITAL OUTS value list are indicators only and cannot be selected.
13) OUTPUT RESOLUTION can be set to 16-Bit UV22HR only when SAMPLE RATE is set to the 44.1-48 kHz range.
SOURCE TO ANALOG OUT Advanced settings: When two sources have been selected, the following Advanced settings become available: To display current routing: 1) Press and hold the SOURCE TO ANALOG OUT button to display the current conguration of analog and digital sources as indicated by the ANALOG OUT LEDs. If the ANALOG OUT LED is on, the source for the corresponding channel pair is the Analog input; if the ANALOG OUT LED is off, the source is the selected digital input. To modify routing: 1) While pressing the SOURCE TO ANALOG OUT button depressed, press the SOFT LIMIT button to select the pair of channels to be modied; the selected pair is indicated by the ashing A/D OVER LEDs. 2) While maintaining the SOURCE TO ANALOG OUT button depressed, press the OUTPUT RESOLUTION button to toggle the selected pair between ANALOG and the selected digital source.
