Connecting Examples

Example at operating it as the ADAT-ANALOG converter

The following connecting schematic is an example of locating the VC-8 between an analog mixer with 8 TAPE IN - 8 BUS OUT (or GROUP OUT) and the VR800 (digital multitrack recorder). In this system, the 8 BUS output from the analog mixer is converted to adat digital signals and the signals of channels 1~8 can be recorded on tracks 1~8 of the VR800.

Note: When connecting to a digital recorder with WORD OUT such as VR800, it always must be connected to WORD IN of the VC-8 and used by input of WORD clock.

Note: When the digital inputs and outputs of the VC-8 and VR800 (or another digital recorder) are connected as shown in above connecting schematic, be sure to set one side as the clock master and the other as the clock slave.

In other words, if the VC-8 had been set as the master, then VR800 (or another digital recorder) must be set as the slave, or if in the reverse situation whereas VC-8 had been set as the slave, then VR800 (or another digital recorder) must be set as the master. The most recommended setting at using the VC-8 is to establish the digital recorder as the master and the VC-8 as the slave as shown in table below.

Recorder	VR800: Asynchronous mode	VR800: Synchronous mode	The most recommended setting. Furthermore, if the
VC-8	Other recorder: Internal mode	Other recorder: External mode	WORD clock can be input, then WORD must be input.
CLOCK switch	VR800 (or recorder): Master	VR800 (or recorder): Slave	This setting is employed if the recorder (general DAT and
	VC-8: Master	VC-8: Slave	MD) has an internal clock and thus cannot accept digital
INT (44.1kHz)			signals.
			Mutual exchanged of digital signals between the equip-
CLOCK switch	VR800 (or recorder): Slave	VR800 (or recorder): Slave	ment is possible by this setting, but deterioration of sound
	VC-8: Slave	VC-8: Slave	quality is unavoidable.
WORD or OPTICAL			This setting cannot be used. A digital loop will be created
			in general type DAT and MD and thus will not operate
			correctly.
