3. Audio Check
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 DM1000.
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.
