8.1 TROUBLESHOOTING

8.2 The ADAT Input/Output Doesn’t Support Optical S/PDIF

The ADAT input/output does not support optical S/PDIF. Optical

S/PDIF is characterized by utilizing two channels, rather than eight.

S/PDIF is carried by a pair of coaxial (RCA-style) plugs on the breakout

cable.

8.3 Pops, Clicks, And/Or Distortion Are Present In The Audio

Signal

Pops, clicks and distortion on the fiber optic I/O may be caused by

Word Clock discrepancies. Word Clock problems arise when the digital

frame rates of two devices are not aligned. In order for two or more

digital devices to be properly aligned only one device can be set as

master. Word Clock allows other deices to be synced or ‘chained’ to

this device. In other words, the ‘chained’ devices are set as slaves.

(Similar to a MIDI daisy-chain). The BNC connectors allow one unit to

be slaved to another unit, which is one way to sync two or more digital

devices. Another way to sync digital Word Clock devices is through the

Word Clock signal that is carried either by the S/PDIF I/O or the ADAT

I/O.

8.4 ADAT I/O Cannot Be Used In Conjunction With The Line Or

S/PDIF I/O

The ADAT I/O cannot be used at the same time as the line or S/PDIF

I/O. For example, ADAT channels one-six and S/PDIF cannot be used

simultaneously. However, you can use the ADAT inputs and the Line

outputs at the same time. In this instance the line outputs will mirror

the ADAT inputs.
