ADJUSTMENT OF COMPRESSION:
LOW BAND:
1) Turn all the THRESHOLD-controls fully counter-clockwise.
2) Turn the LOW BAND GAIN-control fully clockwise.
3) Turn the MID BAND and HIGH BAND GAIN-control fully counter-clockwise.
4) Set the X-OVER LOW at 300.
5) Set the X-OVER LOW multiplier at x4.
6) Apply a signal of 100 Hz, (approx. -20 dBU) to the input and adjust the input level
for an output reading of 0,0dBU.
7) Move the jumper on the low band side chain PCB to “ADJUST” and observe that
the output level has dropped to -10,0 dBU.
8) If this is not the case, adjust the gain reduction with P1, to obtain a drop of -10,0 dB.
9) Adjust the low band display with P2 so the green -10 LED turns on and the
green -7 LED just turns off.
MID BAND:
1) Turn all the THRESHOLD-controls fully counter-clockwise.
2) Turn the MID BAND GAIN-control fully clockwise.
3) Turn the LOW BAND and HIGH BAND GAIN-control fully counter-clockwise.
4) Set the X-OVER LOW at 60.
5) Set the X-OVER LOW multiplier at x1.
6) Set the X-OVER HIGH at 6k.
7) Apply a signal of 1KHz, (approx. -20 dBU) to the input and adjust the input level
for an output reading of 0,0dBU.
8) Move the jumper on the low band side chain PCB to “ADJUST” and observe that
the output level has dropped to -10,0 dBU.
9) If this is not the case, adjust the gain reduction with P31, to obtain a drop of -10,0 dB.
10) Adjust the mid band display with P32 so the green -10 LED turns on and the
green -7 LED just turns off. (050611)
