The DG80-112 sets the conditions for the signal
Sound Check through the analogue circuit, the A/D
converter, the DSP-3 and the D/A Converter.
When the Sound Check is started, the LED display
shows “81”. The Sound Check has two conditions.
If the [RECALL] key is pressed when the LED
display shows “81”, the LED display changes to
“82” and the condition changes to the next as below.
81 : DSP3-1
82 : DSP3-2
Check the following items in each condition of “81”
and “82”.
* 0 dBm = 0.775 V
Load = 4 ohms
If the Sound Check has been finished, press the
[RECALL] key when the LED display shows “82”.
The LED display shows “9”.
