ADJUSTMENT OF THE VU METER READING "COMPRESSION": (980112)
1) Turn the THRESHOLD-control fully counter-clockwise.
2) Switch the METER-selector to Compression.
3) Set the RATIO-control at 2:1
4) Apply a signal of 1 kHz, -20,0 dBU into the input.
5) Adjust the OUTPUTGAIN-control to an output-reading of 0,0 dBU.
6) Adjust P 14 until the meter is reading 0 VU.
7) Apply a DC-voltage of +250,0 mV into the side chain jack socket and observe that
the output level has dropped to -10,0 dBU. If this is not the case, adjust the
compression tracking (see above)
8) Adjust P 13 until the meter is reading -10,0 VU.
9) Remove the DC-voltage from the side chain jack socket (by setting the bus select
switch in the neutral position).
10) Repeat step 6 - 9.
NB: The VU-meter accuracy should be within +/- 0,5 dB when reading compression.
