Digital Connections - Chapter 7

Connections

To a Single ADAT

Connection between the Q20 and one or more ADATs is a simple task of creating a digital audio network that loops all the devices together. When using a single ADAT, simply connect two fiber optic cables between the devices to provide two- way communication.

To connect the Q20 to a single ADAT:

Connect an EIAJ fiber optic cable (such as Alesis OC, OA, or O1) from the [DIGITAL OUT] of the Q20 to the DIGITAL IN of the ADAT.

To test the cable and Q20 digital output, plug one cable end into the Q20. The other end should emit a soft red light (it is not dangerous to look directly at this light).

Connect another fiber optic cable from the Q20Õs [DIGITAL IN] to the DIGITAL OUT of the ADAT .

Note that the ADAT Optical inputs and outputs are 16 bit. This means that a 20 bit signal from an ADAT Type II recorder (M20, ADAT-XT20, ADAT-PCR, etc.) will be truncated down to 16 bits automatically, even if the Q20 is in thru mode. (The S/PDIF I/O is 20 bit. )
