Note: If you are using an SDR24/96 with the Mackie Digital 8Bus console, you may need to turn on the Digital 8Bus first. The Apogee Clock I/O on the D8B prefers not to see an active signal at its Word Clock input when it powers up.

Mackie Media (Optional)

The SDR24/96 emulates the tape library tradition with Mackie Media M90 and Mackie Media PROJECT drives. Both drives come complete with a plug-in tray for quick removal and a nifty storage case for shelving and transporting the drives. The SDR24/96 can record or play directly off the M90 so you can change sessions as quickly as changing tape on a 24-trackno backup time required. PROJECT drives are for backup only and use removable 2.2GB ORB cartridges that fit in your pocket. Each can hold a couple of 5-minute 24-track masters.

Mackie Media Tray

Mackie Media Receiver
To install or remove a Mackie Media tray:
1. Power the SDR24/96 off whenever inserting or removing media trays. If you have an active project, dont forget to save it first! 2. To remove a drive, first unlock it by inserting the key and turning it a quarter-turn counterclockwise. Two keys are packed with the recorder, and one with each M90 drive. 3. Lift the bail handle to release the drive, and pull it out of the drive bay. 4. To install a new M90 or PROJECT drive, slide the media tray into the front panel drive bay. Press it firmly into place, and latch it by pressing the bail handle downward until its fully seated. 5. Insert the key into the lock and turn it a quarter-turn clockwise. The key locks the drive into place and powers the tray. 6. The SDR24/96 will automatically detect the Mackie Media drive when you next power it up.
Note: Mackie Media are hard drives, and as we all know, hard drives involve some pretty intricate technology. So dont shake the little darlin, and if a tray has just come in from a freezing car or airplane cargo hold, do not install it until it has reached room temperature.

Hookups

This section shows how the SDR24/96 is typically connected to both analog and digital consoles (using the Mackie Analog and Digital 8Bus consoles as examples). These examples assume that the rest of your studio equipment (monitors, sound sources, outboard processing, etc.) is already connected, or that you know how to connect it. Before you begin, note how the three analog eight-channel I/O connectors are arranged on the SDR24/96 rear panel: 1-8 is on the left, 9-16 is in the center, and 17-24 is on the right. Labeling each cable before you begin will make connecting the SDR24/96 to your console easier.

Synchronization

The Sync Options menu (under SETUP) allows you to select the sample clock source, sample rate, time code source if time code chase is enabled, frame rate, and sample size. Sample clock source, time code source, LTC output, and MTC output are global settings, and are project independent. Sample rate, frame rate, and sample size are saved in the project file.

Sample Clock

The Sample Clock setting Record I/O Sync Transp (SETUP:Sync:SClk) determines the source of the SDR24/96 sample clock. If SYNC OPTIONS > the SDR24/96 is a clock master or is not SClk SRate TcSrc FrRate connected to any other digital device(s), set it to Internal. If the SDR24/96 is a SAMPLE CLOCK: Internal word clock slave, set it to Word Clock. << >> OK If the SDR24/96 is a slave to a device connected to one of the digital optical inputs, set it to either ADAT A, ADAT B, or ADAT C, depending on which digital port the master device is connected to.

SETUP MENU

Sample Rate
The Sample Rate (SETUP:Sync:SRate) determines how fast the SDR24/96 SAMPLE RATE: 44.1 kHz sample clock runs. Compact Discs use << >> OK a 44.1 kHz sample rate, while some DVD disks use 96 kHz. The video production folks prefer 48 kHz because their digital video recorders use 48 kHz. When 44.1 kHz or 48 kHz is selected, all 24 tracks are available at both the analog and digital inputs and outputs. When 88.2 kHz or 96 kHz is selected, only 12 tracks are available at the digital inputs and outputs. The selected sample rate appears in the status display. If 88.2 kHz or 96 kHz is selected, the X2 LED lights. Use the same sample rate throughout a project.
You must still select the SDR24/96s Sample Rate even if its slaved to another devices clock. If you dont set it correctly, the SDR24/96 time display will run at the wrong rate, even though audio will play at the right speed.

Time Code Chase

The T-CODE CHASE button allows the SDR24/96 to sync to an external time code source. In Play mode, the PLAY LED blinks until the SDR begins receiving valid time code. When valid time code is detected, the PLAY LED lights steadily, the transport jumps to the time code position being received, and playback begins at that point. Note: Looping is disabled when T-CODE CHASE is enabled.

Time Code Source

The SDR24/96 can chase time code << >> from either MIDI IN or SMPTE IN. Use Time Code Source (SETUP:Sync:TcSrc) to select either MTC-Jam Contin, MTC-Chase, LTC-Jam Contin, or LTC-Chase. MTC (MIDI Time Code) is read at the MIDI IN connector, and LTC (Longitudinal Time Code) is read at the SMPTE IN connector.

TC SRC: MTC-Chase

With Chase selected, the transport locks to the incoming time code and the sample rate is adjusted to stay synchronized to the time code. The SDR24/96 must use its internal clock in Chase mode. A good application for using Chase mode is when slaving to an analog tape. If there is wow and flutter from the tape, Chase mode is self-correcting. With Jam Contin (Jam Continuous) selected, once the transport locks to the incoming time code, the transport is governed by the the word clock speed. It is assumed that all devices are synchronized to the same master clock. If not, the time code can drift between devices. Use Jam Continuous mode when the devices are synchronized to the same master clock. Operation Guide

Frame Rate

There are four standard time code frame FRAME RATE: 30 rates, each developed for a specific << >> OK application. In addition, two of the frame rates have variations called drop-frame, mostly used by broadcasters to correct timing issues caused by the 29.97 frame rate. Use Frame Rate (SETUP:Sync:FrRate) to set the time code frame rate to one of the following settings: 24, 25, 29.97, 29.97 Drop, 30, 30 Drop. If youre not involved with video or broadcast applications, 30 frames per second is your best choice.

Sample Size

The Sample Size setting SAMPLE SIZE: 16 bit (SETUP:Sync:Page Right:SSize) << >> OK determines how many bits are contained in each audio sample recorded to disk (the bit resolution). While 16-Bit audio takes up 1/3 less disk space than 24-Bit audio, 24-Bit audio offers the potential for greater dynamic range (the difference between the softest and loudest sounds that can be recorded) and captures a more accurate image of the sound. The selected sample size appears in the status display.

LTC Output

This setting turns the SMPTE LTC OUT on or off (SETUP:Sync:Page Right: Ltc0). Turn this on when the SDR24/96 is generating master SMPTE time code.
GENERATE LTC: Off << >>

MTC Output

This setting turns MIDI time code on or off at the MIDI OUT jack (SETUP:Sync:Page Right:Mtc0). Turn this on when the SDR24/96 is generating master MIDI time code (MTC).
GENERATE MTC: Off << >>

Varispeed

The Varispeed setting (SETUP:Sync:Page Right:VariSp) allows you to speed up or slow down the playback speed in percentages (an increase of 1 percent means it only takes 0.9 seconds to play back a second music) or semitones (an increase of 1 semitone is a half-step on the musical scale). It does this by varying the sample rate speed.
VARISPEED: +1.00 % > Units Zero OK Cancel VARISPEED: +1.00 sem > Units Zero OK Cancel < VARISPEED: +1.00 % << >> Inc Dec
Select Units to toggle between percent (%) and semitones (sem). Press the Page Right button to access the increment (Inc) and decrement (Dec) controls to adjust the speed. Select Zero to return to 0% (no change in speed). The VARI LED lights in the status display whenever varispeed is activated.

SDR24/96 Operation

Now that youve finished installing and configuring the SDR24/96, youre almost ready to start your first Project. We still want you to read this entire guide, but we already hear some of you shuffling and muttering. Okay, okay, okay. for the terminally impatient, read this chapter, then you can go out and play with your friends. This section explains all you need to know to run a basic recording session: opening and creating Projects, operating the Transport, setting levels, and recording and overdubbing tracks. After youre done recording, you will learn how to back up your project to Mackie Media M90, Mackie Media PROJECT drives, and an external drive via the USB port.

Feel The Love << >> Open Cancel
4. If the selected project has more Feel The Love v1 than one project file, the Open << >> OpenAs Cancel button changes to OpenAs. Use the << / >> buttons to scroll through the list of project files that are contained within the project, then press OpenAs. Project opened appears in the display, and then the name of the project. Note: The name of the original project appears in the display, regardless of which version of the project (project file) is open.

Saving a Project

Whenever you record new audio, the audio data and project information is automatically saved to disk. However, if you make other changes to the project, such as edits or I/O settings, you must save the project for the changes to be remembered.

To save a Project:

1. Press Project. In the Project Files Menu, select Save.
PROJECT FILES MENU > New Open Save SaveAs Save current project? OK Cancel
2. A message appears in the display asking you to confirm the save. Select OK or Cancel.
You can save a project under a new name with the Save As command. All the project information is saved in a new project file, but in the existing project folder. This allows you to create backup copies as you work on a project, or to create different versions of the project.
A project file is the part of a Project that keeps track of all your recording and editing, and controls what you hear when you hit Play. A project can contain any number of project files. Since the audio referenced in one project file can be used in any project file, you can create multiple versions of the same song without affecting the original recording. For example, you can create dance and extended play mixes from a CD mix. Or, you can build an entirely new song and borrow parts from other project files.
To save a current Project As:
1. Press Project. In the Project Files Menu, select SaveAs.
PROJECT FILES MENU > New Open Save SaveAs SAVE PROJECT AS: > SaveAs Cancel
2. The SAVE PROJECT AS screen appears. Select SaveAs to accept the existing project name. This works the same as the Save command.
To give the project a unique < Feel The Love v2 name, press the Page Right << >> Inc Dec button. A blinking cursor appears over the first character of the name. Use the increment (Inc) and decrement (Dec) buttons to change the highlighted character. It scrolls through a modified ASCII character set. Use the >> button to move to the next character. 3. Press the Page Left button when finished, and then select SaveAs. Project saved appears in the display to confirm that the project was successfully saved.

Serial 9-Pin

The SERIAL 9-PIN connector on the rear panel of the SDR24/96 is provided for connecting transport controllers that use the EIA RS-422 serial data communication standard. It supports the Sony 9-Pin protocol. The following transport functions can be controlled through the Serial 9-Pin connection: Stop, Play, Rec, Fast Forward, Rewind, and Scrub.

Time Display

The Current Time display shows the exact position of the SDR24/96s playback head. In the current version, the time format can be displayed only in SMPTE time (HH:MM:SS:Frames).

Transport Menu

The SDR24/96 transport menu allows you to set locate points, offsets, and enable AutoPlay.

Use the increment (Inc) and decrement (Dec) buttons to change the highlighted numeral. Use the >> button to move to the next numeral.

6. Press the Page Left button when finished, and then select OK to save the new locator time.

Transport Offset

Transport offset is a preset amount of time that is added to the transport locator positions displayed. For example, if the transport offset is set to 00:01:00:00, the rewind function will stop at 00:01:00:00 instead of 00:00:00:00. The transport offset time is added to all locates, and to incoming and outgoing LTC and MTC.

6. Press the Page Left button when finished, and then select OK to save the new transport offset time.

Relative Offset

Just as transport offset adds a preset amount of time to the transport locator positions, relative offset subtracts a preset amount of time from the transport locator positions when relative mode is turned on (see Relative Mode next). For example, if the relative offset is set to 00:01:00:00, the rewind function will stop at 23:59:00:00 instead of 00:00:00:00 (at 44.1 kHz and 48 kHz sample rates). The transport offset time is subtracted from all locates as well.
To set the relative offset time:
SETUP MENU > Record I/O Sync Transp TRANSPORT OPTIONS > Loc1 Loc2 Loc3 Loc4 < TRANSPORT OPTIONS > CurLoc TrOf RelOf RelMd
2. Select Transp. to enter the TRANSPORT OPTIONS menu. 3. Press the Page Right button and select RelOf. The current relative offset time appears in the display. 4. Select Zero to reset the relative offset time to zero.
RELATOF: 00:01:00:00 > Zero OK Cancel
5. Press Page Right to change < RELATOF: 00:02:00:00 the relative offset time. A << >> Inc Dec blinking cursor appears over the first numeral of the relative offset time. Use the increment (Inc) and decrement (Dec) buttons to change the highlighted numeral. Use the >> button to move to the next numeral. 6. Press the Page Left button when finished, and then select OK to save the new relative offset time. Note that the relative mode must be turned on for the relative offset time to affect the transport locator positions.

Relative Mode

Relative mode can be turned on and off with this command. When relative mode is on, the decimal point in the right side of the current time display lights. In relative mode, the relative offset time is subtracted from the transport locator time (see previous topic). This allows you to work with time coordinates relative to a certain position. Operation Guide
To turn on the relative mode:
1. Press SETUP to enter the SETUP MENU. 2. Select Transp. to enter the TRANSPORT OPTIONS menu. 3. Press the Page Right button and select RelMd. Use the << / >> buttons to select On or Off, then select OK to change the relative mode.
SETUP MENU > Record I/O Sync Transp TRANSPORT OPTIONS > Loc1 Loc2 Loc3 Loc4 < TRANSPORT OPTIONS > CurLoc TrOf RelOf RelMd RELATIVE MODE: On << >> OK

AutoPlay

When AutoPlay is on, the transport automatically starts playing when you jump to a locate point.

To turn on autoplay:

SETUP MENU > Record I/O Sync Transp TRANSPORT OPTIONS > Loc1 Loc2 Loc3 Loc4 < TRANSPORT OPTIONS AuPlay AUTOPLAY: On << >> OK
2. Select Transp. to enter the TRANSPORT OPTIONS menu. 3. Press the Page Right button twice and select AuPlay. Use the << / >> buttons to select On or Off, then select OK to change the autoplay mode.
Locate Points and Looping
Locate points provide fast access to frequently used locations in your Project. Looping allows you to playback or record a section of the project repeatedly, from a preset starting time to a preset ending time.

Locate

The SDR24/96 has four numbered Locates. The numbered Locates can be set either from the front panel or an optional remote. Storing a Locate point saves the Current Time (Transport position) to the selected Locate. Recalling a Locate causes the Transport to jump to the stored time.
To recall a Locate point:
1. Press LOCATE. The Locate LED lights.
2. JUMP TO LOCATOR appears in JUMP TO LOCATOR: the display. Select one of the four Loc1 Loc2 Loc3 Locate points in the display (Loc1, Loc2, Loc3, Loc4). The transport automatically jumps to the selected Locate point (and the Locate LED goes out).
To store numbered Locate points:
Locate points can be stored either on the fly or when stopped. 1. Press STORE. The Store LED lights.

E STORE

2. STORE LOCATOR appears in STORE LOCATOR: the display. Select one of the Loc1 Loc2 Loc3 Loc4 four Locate points in the display (Loc1, Loc2, Loc3, Loc4) when the transport is at the desired location. The Store LED goes out, indicating that the Locate point has been stored.
Looped playback is determined by the selected locator mode (SETUP:Record:Page Right:LocMd).
With Loop1-2/Punch3-4 selected, Locates 1 and 2 double as start and end points for looped playback. When looping is enabled, playback cycles between the Loop Start and Loop End points. Locates 3 and 4 serve as punch in and punch out points when Auto Punch is enabled (the PUNCH button). The order of the Loop points does not matter. If the current locator time is before or between the Loop points when loop is enabled, playback continues from its current position until it reaches the Loop End point, and then jumps back to the Loop Start point. If the current locator time is after the Loop End point, looping will not occur. With Loc3-4 PreR/PostR selected, Locates 3 and 4 double as start and end points for looped playback (Locates 1 and 2 do not loop). If Auto Punch is enabled, Loc3 and Loc4 become the Punch-in and out points. The preroll time (SETUP:Record:PreRo) is subtracted from the Punch Start point, and the postroll time (SETUP:Record:PostRo) is added to the Punch End point to create the looping points.

Note: Looping is disabled when T-CODE CHASE is enabled.

To enable Looping:

1. Press LOOP to enable looping. Looping can be enabled during Stop, Play, Fast Forward, or Rewind.

Recording

All recording in the SDR24/96 is non-destructive. When you record over existing audio, the old audio is not erased as it with magnetic tape; rather, new audio files are created in addition to the existing files. Audio files are recorded in native Wave format (.WAV). Recording can only take place on tracks that are armed for recording.
To arm tracks for recording:
1. Press a tracks Record Ready button. 2. Press it again to disarm the track.

Record Ready LED

Record Ready The red Record Ready LED, located at the bottom of the meter directly above the Record Ready button, blinks when a track is armed and ready to record, and Operation Guide glows when the track is recording.

To record:

1. Arm one or more tracks.

PLAY RECORD

2. Press RECORD and PLAY at the same time. Record can be activated during Stop or Play. If One Button Record is enabled, Record can be activated during play just by pressing the RECORD button. 3. Press any transport button other than RECORD to stop recording. The Record LED glows when the SDR24/96 is recording and blinks when RECORD is engaged with no tracks armed (master record standby mode). Post-record processing time: After a record pass, the SDR takes a few moments to process the recording that has just taken place and update the project file. The longer the recording, the longer this processing time takes. For full 24-track recording that lasts for eight or ten minutes, the post-processing time could take up to a minute. During this time, the STOP LED blinks and all transport functions are disabled.

Track Options

Each of the 24 tracks on the SDR24/96 has 8 virtual tracks associated with it. Virtual tracks are used to record multiple takes, so you can compare the takes and decide which one to keep. Only one virtual track can be active at at time. You can give a unique name to each track to help you remember what is recorded on each track. You can also mute individual tracks.
The Track Mute menu (TRACK:Mute) toggles muting for each track. When a track is muted, its corresponding meter is also muted (no indication).
TRACK OPTIONS Mute Virtual Name
Use the Page Right button to page through the various tracks, and use the SELECT buttons to toggle the mute for each track. An asterisk (*) indicates the track is muted.

Mount Drive

Select Mount (SETUP:Page Right:Disk:Mount) anytime you change drives in the Mackie Media Bay. The SDR24/96 takes a look at the internal and external drives and checks to see if the media has changed. When the operation is complete, Disk mount complete appears in the display.
SETUP MENU > Record I/O Sync Transp < SETUP MENU Disk System DISK UTILITY MENU Mount Format Defrag

Format Drive

The Format utility (SETUP:Page Right:Disk:Format) completely erases the data on the hard drive and creates a new FAT32 partition, which fills the entire drive space. All media must be formatted before it can be used with the SDR24/96. Mackie Media M90 drives come pre-formatted and ready to use, as do ORB disks for the Mackie Media PROJECT drive (be sure to buy IBM formatted ORB disks).

To format a drive:

1. Press SETUP to enter the SETUP MENU. 2. Press Page Right, select Disk, and then select Format. 3. If there are multiple drives, the SELECT DRIVE: External Select Drive menu asks you to << >> Next select the drive to format. Select either Internal or External using the << / >> buttons. The selection defaults to the drive containing the currently open Project. Select Next. 4. You are asked to confirm the format command. Select OK to proceed or Cancel to exit.
Format external drive. Proceed? OK Cancel
5. While the drive is formatting, the display indicates the progress of the operation in percentages.

Defrag Drive

The Defrag option (SETUP:Page Right:Disk:Defrag) allows you to defragment a drive. As files are written, edited, and deleted on a disk, the files can become fragmented. The SDR24/96 still keeps track of the data, but it can slow down access to the files. Defragmenting a drive puts all the files back together in contiguous streams of data. As a precaution, we recommend backing up the data on the hard drive before running the defrag operation.

To defragment a drive:

1. Press SETUP to enter the SETUP MENU. 2. Press Page Right, select Disk, and then select Defrag.

Front Panel Description

Channel Level Indicators: Indicate the signal level at the inputs or outputs, depending on the monitoring mode selected. OL on the meter corresponds to +22 dBu at the analog input, and 0 dBFS at the digital input. Record Ready Buttons: Used to arm tracks for recording, or to select tracks for editing. The red LED at the bottom of the meter blinks while in Record Standby, and lights steadily while actually recording. POWER Switch: Turns the SDR24/96 on and off. Drive Bay: For removable drives like the Mackie Media M90 and the Project ORB cartridge. DELETE LAST: Deletes the last record pass (must be the last action in the History List). You cannot undo Delete Last. TRACK: Accesses track options including Mute, Virtual Tracks, and Track Name. PROJECT: Accesses project options including New, Open, Save, Save As, Delete, Copy, Rename, and Purge. EDIT: Accesses common editing functions such as Delete, Cut, Copy, Paste, Place, Undo, and Redo. SETUP: Accesses the following options: Record Options Record Safe Locator Mode Preroll before Locator Auto Take Mode Preroll One Button Record Postroll I/O Options Track Input Select Input Type Select Track Output Select Sync Options Sample Clock Sample Size Sample Rate LTC Out Time Code Source MTC Out Frame Rate VariSpeed Transport Options Locate 1-4 Relative Offset Current Locator Position Relative Mode Transport Offset Auto Play Disk Options Mount Drive Defragment Drive Format Drive System Options USB Mass Storage Mode System Load SDR Footswitch Date Remote Footswitch Time About
Choose either the analog inputs or digital inputs using the INPUT TYPE SELECT menu (SETUP:I/O:Page Right Twice :INPUT TYPE SELECT), or customize a combination of both. See Hookups on page 12 of the Operation Manual for examples of both analog and digital connections. By default, track numbers are assigned to their corresponding inputs and outputs. You can customize the mapping of the inputs (SETUP:I/O:TRACK INPUT SELECT) and outputs (SETUP:I/O:Page Right : TRACK OUTPUT SELECT) to different tracks.
Choose the sample clock source (SETUP:Sync:SClk). If the SDR24/96 is providing the master clock, select Internal. If the SDR is a slave and syncing to an external clock through the Word Clock input, select Word Clock. Select ADAT A, B, or C if syncing to a selfclocking ADAT optical input. Choose the sample rate (SETUP:Sync:SRate). When recording with the analog inputs, choose any sample rate appropriate for your project. You must use the same sample rate throughout a project. When recording with the digital inputs, the sample rate must be the same as the digital source. Choose your preferred sample size (SETUP:Sync:Page Right :SSize), either 16-bit or 24-bit. Choose the time code source (SETUP:Sync:TcSrc) if the SDR is chasing to time code (T-CODE CHASE). Use Jam Continuous when all devices are synced to the same master clock. Use Chase when the you are using the SDR24/96s internal sample clock (no external clock connected) and you want to sync to external time code.

AUTO TAKE: Used for multiple record passes. When Auto Increment mode is selected, virtual track numbers are automatically incremented after each record pass. In Auto Edit mode, multiple recordings take place on the same virtual track, but previously recorded audio for the take is shifted down to the next virtual track. T-CODE CHASE: Allows the SDR24/96 to sync to external time code. LOCATE: Jump to Locate 1, 2, 3, or 4. STORE: Store Locate points 1-4. LOOP: Enables looped playback or recording. PUNCH: Enables Auto Punch mode. REHEARSE: Use to practice punching-in and punching-out. Punch-in and punch-out points are automatically saved to Locates 3 and 4, respectively. ALL INPUT: Both armed and unarmed tracks monitor their inputs in Play and Record. Use for rehearsing and level-setting. AUTO INPUT: Both armed and unarmed tracks monitor their previously recorded audio in Play, and armed tracks monitor their inputs in Record (unarmed tracks still monitor their previously recorded audio). Use for recording. Status Display: Error, Sample Rate, Word Length, VariSpeed, and Time Code Sync indicators. Current Time Display: Shows the current locator time in Hours:Minutes:Seconds:Frames. EXT CLOCK: Indicates when the SDR24/96 syncs to an external clock. LCD Display: Backlit 2x24-segment display provides selection options for the four SELECT buttons. Page Left and Page Right Buttons: Used to scroll through the menus in the display. SELECT Buttons: Used to select options in the display.
