Audio Level Adjustment
Set the RECORD level control R2 and the PLAYBACK level control R3 to mid-range. This
set the audio path through the DVR at approximately unity gain. Use R2 and R3 to
adjust the audio levels as desired. Measure the TX1 audio level at TP5. Adjust R3 so
the playback audio at TP5 is the same level as the audio of the original signal.
Expanded User Function Switches
The eight expanded user function switches are open collector relay drivers. Each
driver can sink up to 80mA and switch 40 VDC. When connected to the CAT-1000B, use
the second expanded user function table, controlled by the [580] default prefix code.
Place diodes across the relay coils to protect the driver from negative spikes
produced when the relay coil collapses.
