3.2
For the case that the POWER AMP switch is 'MAIN BRIDGE'
3.2.1 Preparation
•
POWER AMP switch: MAIN BRIDGE
•
INPUT terminal: CH 5 LINE 1
•
MASTER (MAIN): MAX
•
OUTPUT terminal: BRIDGE
•
Load Resistance: 8
Ω
(more than 600W)
Except otherwise indicated, the load resistance of SPEAKER should
be connected only for the amplifier check.
•
LEVEL control of CH1-4, 6: MIN
•
Except the above, same as the setting of 2.1
3.2.2 Gain Check
Apply -26.0dB signal into input terminal, and confirm that the output level of 22.0
±
2 dBs can be gained.
3.2.3 Frequency Response Check
Apply -26.0dBs signal into input terminal, and confirm that the output level for 20Hz, 20kHz signal are 1, -3dB from the
level for 1kHz signal.
4.
Miscellaneous
4.1
Power Supply Voltage Variation
Change the voltage of power supply in the range of
±
10%, and confirm that the system works normally.
