2.9 Audio Monitor Connections<br />
Processed, de-emphasized samples of the left and right audio inputs to the stereo<br />
generator are available at the Monitor jacks on the rear panel. The signals are<br />
suitable for feeding a studio monitor and for doing audio testing. De-emphasis is<br />
normally set for 75 µsec; set to 50 µsec by moving jumpers, JP203 and JP204, on<br />
the Stereo Generator board.<br />
2.10 Pre-emphasis Selection<br />
Select the pre-emphasis curve (75 µsec, 50 µsec, 25 µsec, or Flat) by jumpering the<br />
appropriate pins of header JP1 on the audio processor board. If you change the preemphasis,<br />
change the de-emphasis jumpers JP203 and JP204 on the Stereo<br />
Generator board to match.<br />
