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.
  * Don't connect the R-BUS connector to an RMDB connector, SCSI connector, RS-232C connector, or parallel connector. Doing so will cause malfunctions.
  * Don't connect or disconnect the R-BUS connector while the power is turned on. Doing so will cause malfunctions.

The illustration shows the MV-8800 rear panel when the separately sold MV8-OP1 option is installed.

The jacks shown in items 1–3 are available if the MV8-OP1 AUDIO I/O EXPANSION (separately sold) is installed. You can make output settings from the INSTRUMENTS screen (Screen Guide; p. 114) and the PARTIAL EDIT screen (Screen Guide; p. 125).

1 DIGITAL IN Connectors

These are digital audio input connectors. "A" is a coaxial type connector, and "B" is an optical type connector.

② R-BUS Connector

This is a digital 2-channel input/8-channel output connector. You can also set the input select setting to receive audio input from R-BUS channels 1 and 2, or use the R-BUS channels 1–8 to output the audio from the MULTI OUTPUT bus.

③ ANALOG MULTI OUTPUT Connectors

These jacks output the audio from the MULTI OUTPUT bus.

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 doesn't 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.

● The audio signal of multi output 7 and 8 cannot be output via analog multi output.

Inputting audio via a digital connection (coaxial/optical)

The MV-8800 has both coaxial and optical type digital input connectors. You must choose either one or the other type. You cannot use both simultaneously.

1. Connect your digital audio device to the MV-8800.
2. Press [SYSTEM].

The SYSTEM MENU screen (Screen Guide; p. 172) will appear.

1. With the cursor located in the upper row of icons, press F1. Alternatively, select the GLOBAL icon and press [ENTER].

The GLOBAL screen (Screen Guide; p. 173) will appear.

1. 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

Here's 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].

The SYSTEM MENU screen (Screen Guide; p. 172) will appear.

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	Explanation
External	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-OP1's R-BUS connector will match the sampling rate of the external R-BUS device.
Internal 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-8800's 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].

The SYSTEM MENU screen (Screen Guide; p. 172) will appear.

1. With the cursor located in the upper row of icons, press F1. Alternatively, select the GLOBAL icon and press [ENTER].

The GLOBAL screen (Screen Guide; p. 173) will appear.

1. 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 3–8 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-8800's multi outputs via the R-BUS connector (digital) on MV8-OP1.

1. Connect the MV-8800 with your output destination device.

2. Press [MIXER].

The MIXER (AUDIO TRACK) screen (Screen Guide; p. 235) will appear.

1. Set the Output parameter to MLT1-8 or M1/2-7/8.

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	Destination bus R-BUS output channel
MLT1	Multi output 1 1
...
MLT6 Multi output 6 6
MLT7 Multi output 7 7
MLT8 Multi output 8 8
M1/2 Multi output 1/2 1 and 2
M3/4 Multi output 3/4 3 and 4
M5/6 Multi output 5/6 5 and 6
M7/8 Multi output 7/8 7 and 8

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