Calibration Procedure
(continued)
Channel Clip Indicator Test:
1. Input a 500Hz signal @ +15dBu into the channel A [B] input.
2. Verify that the channel A [B] clip indicator is on and that all of the level indicators are on.
3. Change signal input level to +13dBu and verify that the channel A [B] clip indicator turns off
while leaving the level indicators on.
Sub Woofer Test:
1. Input a 50Hz signal @ -lOdBu into channel A [B] input.
2. Measure the sub woofer output with the DVM set to A.C. volts.
3. With the SUB Frequency control and the SUB Woofer Level control at minimum (fully
C.C.W.), DVM should read less than -70dBu.
4. With SUB Woofer Level control at maximum (fully C.W), DVM should read -9.0dBu
(+/- O.SdBu).
5. With SUB Frequency control at maximum (fully C.W), DVM should read -4.0dBu
(+/- O.SdBu).
Sub Woofer Clip Indicator Test:
1. Input a 50Hz signal @ +9dBu into the channel A [B] input.
2. Verify that the SUB Woofer clip indicator is on.
3. Change signal input level to +6dBu and verify that the SUB Woofer clip indicator turns off.
