CAUTION!
Be sure to press the [END] button to complete
the Audio Check. If the [END] button is not
pressed and the power is turned OFF, the current
memory data of the unit will be erased and the unit
will not return to the condition before the check.
However, if the current memory data: Scene
Memory, Input Patch Library, Output Patch Library,
Surround Monitor Library, and Automix are saved
before starting the Audio Check, this data can be
recovered but other data must be reset.

3-1. Outline

Execute the Audio Check for 01V96.
Check method
Insert the voice signal in the ANALOG, SLOT, and
2TR Digital input, select INPUT CH 1 to 48, and
check the headphone output. If the voice signal
input is not correctly output, the LSI on the selected
signal route is faulty.
Because the built-in oscillator (1 kHz/-20 dB, sine
wave) is output to BUS 1 to 8 and AUX 1 to 8,
select BUS 1 to 8 and AUX 1 to 8 and check
ANALOG, SLOT, and 2TR Digital output set in the
OUT PORT. If the sine wave is not correctly output,
the LSI on the selected signal route is faulty.
