2.9 Audio Monitor Connections
Processed, de-emphasized samples of the left and right audio inputs to the stereo genera-
tor are available at the Monitor jacks on the rear panel. The signals are suitable for feeding
a studio monitor and for doing audio testing. De-emphasis is normally set for 75 µsec; set to
50 µsec by moving jumpers, HD201 and HD202, on the Audio Processor/Stereo Generator
board.
2.10 Pre-emphasis Selection
Select the pre-emphasis curve (75 µsec, 50 µsec, 25 µsec, or Flat) by jumpering the appro-
priate pins of header HD1 on the Audio Processor/Stereo Generator board. If you change
the pre-emphasis, change the de-emphasis jumpers HD201 and HD202 on the Audio Proc-
essor/Stereo Generator board to match.
