BBE 362SW - Manual (Page 14)

Calibration Procedure
Note: This unit was caiibrated at the factory.
This procedure is for quaiified service personnei oniy.
Initial Settings:
1. Sub Frequency control VR4, Sub Woofer Level control VR3, BBE Process control VR2, LO
Contour VR1 to minimum, (fully counterclockwise)
2. Power Switch on and BBE Function Switch in (Process On).
Power Supply Test:
1. With DVM set to D.C. volts, measure the positive end of C37. You should read less than +30
VDC.
2. With DVM set to D.C. volts, measure the negative end of C39. You should read less than -30
VDC.
BBE Process Test:
1. Input a 5kHz signal @ -lOdBu into channel A [B] input
2. Measure the channel A [B] output with the DVM set to A.C. volts.
3. With process control at minimum (fully C.C.W), DVM should read -lO.SdBu (+/- O.SdBu).
4. With process control at maximum (fully C.W.), DVM should read -2dBu (+/- O.SdBu).
Lo Contour Test:
1. Input a 50Hz signal @-lOdBu into channel A [B] input.
2. Measure the channel A [B] output with the DVM set to A.C. volts.
3. With Lo Contour control at minimum (fully C.C.W), DVM should read -lOdBu (+/- O.SdBu).
4. With Lo Contour control at maximum (fully C.W), DVM should read -I.SdBu (+/- O.SdBu).
Bypass Test:
1. Input a 500Hz signal at -lOdBu into channel A [B] input.
2. Measure the channel A [B] output with the DVM set to A.C. volts.
3. With the Process in, the DVM should read -1 IdBu (+/- O.SdBu) and the Process LED should
illuminate green.
4. With the Process out, the DVM should read -1 O.SdBu (+/- O.SdBu) and the Process LED
should illuminate red.
