10.2.1 PROGRAMMING
The mode of operation (programming) is selected by activating one of the touch buttons marked A:8/B:8,
A:16, B:16.
The programming buttons illuminate when pressed and function as follows:
A:8/B:8 – splits input A to outputs 1A – 8A and input B to outputs 1B – 8B repectively.
A:16 – splits input A to all outputs 1A – 8A and 1B – 8B
B:16 – splits input B to all outputs 1A – 8A and 1B – 8B
10.2.2 INDICATION
Each channel has two status LEDs. The GREEN one indicates the presence of data and the RED
one indicates an ERROR within the digital audio signal. When a valid digital audio signal is detected, the
corresponding GREEN LED is lit. The RED LED may light up when there is no signal on the
corresponding input (GREEN LED off). When the RED LED is lit together with the GREEN LED, it is an
indication that the signal at the input is either a non-standard signal or it has errors. For normal operation,
the GREEN LED is lit and RED LED is unlit.
The built-in “watch dog” circuitry checks each and every frame of the digital audio signal. If an
ERROR appears in a frame, the RED LED is illuminated for about half a second.
11 TAKING CARE OF YOUR MACHINE
Do not locate your machine in an environment where it is susceptible to dust or moisture. Both of
these may damage the electronics, and cause erratic operation or failure. Do not locate your machine
where temperature and humidity may be excessive. Doing so may also damage the electronics, and cause
erratic operation or failure of your machine. Do not clean your machine with abrasives or strong cleaners.
Doing so may remove or damage the finish, or may allow moisture to build up. Take care not to allow
dust or particles to build up inside unused or open connectors.
