* Power is supplied to the DIF-AT24 via the R-BUS connector.
ADAT OUT/IN (ADAT digital out/in) connector This is the ADAT digital interface. It allows eight channels of digital audio data to be transferred between the DIF-AT24 and an ADAT-compatible digital device. R-BUS connector Provides for the input/output of eight channels of digital audio data, thus allowing the exchange of data between the DIF-AT24 and an R-BUS device to take place. Also transmits/receives synchronization signals.

Rear Panel

MIDI IN/OUT connectors These are used mainly for MTC synchronization.
The data that is transmitted from the MIDI OUT connector will depend on the settings of the R-BUS device connected to the R-BUS connector.

Connect only an R-BUS device to the R-BUS connector. You must never connect a device with a SCSI, RS-232C, or parallel interface. Even though the connectors on such devices may look similar, they are incompatible, and damage and/or malfunction could result if you attempt their connection. Also, you must use only a special R-BUS cable to make connections. You must turn off the power of the R-BUS device before connecting or disconnecting the R-BUS cable. If you connect or disconnect the cable while power is being supplied, the external R-BUS device will stop working correctly, and the DIF-AT24 or the external R-BUS device may also be damaged. The specifications for R-BUS are identical to those of RMDB2 and RMDB II. You can use it with any device that is marked RMDB2 or RMDB II. R-BUS (RMDB2) is not compatible with the older RMDB specification.

Turning the power on/off

Turning the power on
Before you turn each device on, make sure that all devices are connected correctly. Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/ or damage to speakers and other devices.

About the MV8-OP1
The MV8-OP1 AUDIO I/O EXPANSION (sold separately) is an expansion board that adds six analog multi-outputs, digital inputs (coaxial type and optical type), and an R-BUS connector to the MV-8800. Installing the MV8-OP1 adds the following functionality. You can digitally connect a digital audio device (CD player, MD player, DAT recorder) and sample without impairing the audio quality. You can input digital audio of a variety of sampling frequencies.
* Since the MV8-OP1 contains a sampling rate converter, there is no limitation on the sampling frequencies that can be input. All signals will be converted to 44.1 kHz.
You can connect devices that have an R-BUS connector, such as the Roland VS-2480CD or XV-5080, for digital audio input/output via R-BUS (2-channel input / 8-channel output). You can individually output the audio signals of the MV-8800 to its multi outputs. This is convenient when you are using the MV-8800 with an external mixer. (Analog output and R-BUS output are all available.) When used with the DIF-AT24 (sold separately), an additional MIDI IN and OUT (16 channels) is added.
* Dont connect the R-BUS connector to an RMDB connector, SCSI connector, RS-232C connector, or parallel connector. Doing so will cause malfunctions. * Dont connect or disconnect the R-BUS connector while the power is turned on. Doing so will cause malfunctions.

Installing the MV8-OP1
Precautions for expanding option
Always turn the unit off and unplug the AC plug before attempting installation of the MV8-OP1.
Install only the specified option. Remove only the specified screws. To avoid the risk of damage to internal components that can be caused by static electricity, please carefully observe the following whenever you handle the board. Before you touch the board, always first grasp a metal object (such as a water pipe), so you are sure that any static electricity you might have been carrying has been discharged. When handling the board, grasp it only by its edges. Avoid touching any of the electronic components. Save the bag in which the board was originally shipped, and put the board back into it whenever you need to store or transport it. Do not touch any of the printed circuit pathways. Never use excessive force when installing a circuit board. If it doesnt fit properly on the first attempt, remove the board and try again. When circuit board installation is complete, double-check your work. When turning the unit upside-down, get a bunch of newspapers or magazines, and place them under the four corners or at both ends to prevent damage to the buttons and controls. Also, you should try to orient the unit so no buttons or controls get damaged. When turning the unit upside-down, handle with care to avoid dropping it, or allowing it to fall or tip over. Use a Philips screwdriver of the appropriate size to avoid damaging the screw heads (a number of 2 screwdriver). If an unsuitable screwdriver is used, the head of the screw may be stripped. Turn the screwdriver counter-clockwise to loosen the screws-turn it clockwise to tighten them.

4. Set the Input Select parameter to either Coaxial or Optical.
Select Coaxial if you want to input from the coaxial connector (DIGITAL IN A), or select Optical if you want to input from the optical connector (DIGITAL IN B). When you change the setting, the illustration of the input connector in the GLOBAL screen will also change.

Transferring digital audio via R-BUS
If the MV-8800 is connected to another device that has an R-BUS connector, you can use two channels of digital audio input and eight channels of digital audio output.
Caution when connecting an R-BUS device
You may connect only another R-BUS device to the R-BUS connector. Even if the connector has the same shape, you must never attempt to connect a SCSI, RS-232C, or parallel interface. Doing so will cause malfunctions. Use an R-BUS cable (RBC-1 or RBC-3: each sold separately) to make connections to an R-BUS connector. Before connecting or disconnecting the R-BUS cable, you must turn off the power of the MV-8800 and the other R-BUS device. If you make connections while the power is on, the system may fail to operate correctly, and malfunctions may also occur. R-BUS is the same specification as RMDB2 and RMDB II. It can be used without any problems with devices marked RMDB2 or RMDB II. R-BUS is not compatible with RMDB. The RBC-5 (5 meter R-BUS cable: no longer available) cannot be used with the MV-8800. Please use the RBC-1 (1 meter R-BUS cable) or RBC-3 (3 meter R-BUS cable).
Making word clock settings
Heres how to specify whether the word clock master device (the device that produces the synchronization signal that regulates transmission and reception of digital audio signals) will be the MV-8800 itself or the external device connected to the R-BUS connector.
For details on word clock, refer to Digital Connection with the Word Clock (p. 10).

1. Press [SYSTEM].

2. With the cursor located in the upper row of icons, press [F2](R-BUS). Alternatively, select
the R-BUS icon and press [ENTER].
The R-BUS screen (Screen Guide; p. 183) will appear.
3. Set the Word Clock parameter.
Normally, you should use the External setting.
Value External Explanation The word clock will be received from an externally connected R-BUS device. In this case, the sampling rate of the signal sent from the MV8-OP1s R-BUS connector will match the sampling rate of the external R-BUS device. The word clock (44.1 kHz) will be generated inside the MV-8800, and transmitted via the R-BUS connector. Set the external R-BUS device connected to the R-BUS connector to operate as the Slave. The signal transmitted from the MV-8800s OUTPUT DIGITAL and the internal processing of the sampling functionality and the like is always 44.1 kHz.

Digital Connection with the Word Clock
Ordinarily, word clock is generated within, and output by the device transmitting digital signals (the master). Meanwhile, the receiving device (the slave) receives the word clock and adjusts its operation (synchronizes) to that clock. This means that the operation of the transmitting and receiving devices is based on the same sampling rate. With some devices, however, the sampling rate used may differ. The digital circuitry of the MV8-OP1 (optional), which can be combined with the MV-8800, features a built-in sampling rate converter. This enables reception of digital signals, even when the sampling rate of the received signals differs. The digital signals transmitted from the R-BUS are matched to the received sampling rate. Also, with some R-BUS devices, you could encounter situations such as the following: No word clock can be generated (only slave operation is available) Due to circumstances with the connection, the device needs to be set to receive word clock (slave). In such situations, you can make the MV-8800 the word clock master by setting it to Internal. However, the sampling rate of the digital signals output from the R-BUS will be fixed at 44.1 kHz.
Inputting digital audio into R-BUS
1. Connect the MV-8800 with your R-BUS device. 2. Press [SYSTEM].
4. Set the Input Select parameter to R-BUS.
Audio can now be input via R-BUS channels 1 and 2. When you switch the setting, the illustration of the input connectors shown in the GLOBAL screen will also change.
You cannot use R-BUS channels 38 to input audio into the MV-8800. Since the MV8-OP1 contains a sampling rate converter, there is no restriction on the sampling rates that can be input. All signals will be converted to 44.1 kHz.

Outputting digital audio from R-BUS
You can output the audio from the MV-8800s multi outputs via the R-BUS connector (digital) on MV8-OP1.
Set the Output parameter of the part whose signal you want to send to the multi output bus. The signal sent to each bus will be output via R-BUS.
Value MLT1 : MLT6 MLT7 MLT8 M1/2 M3/4 M5/6 M7/8 Destination bus Multi output 1 : Multi output 6 Multi output 7 Multi output 8 Multi output 1/2 Multi output 3/4 Multi output 5/6 Multi output 7/8 R-BUS output channel 1 : and and and and 8

The identically-numbered R-BUS and analog multi output will output the same audio.
