FOR-22 Pin-Out
The audio input / output via the DB-9 connector has a manual adjustment range via the front panel of the FOR-22 of 10dB.
Additionally the FOR-22 output range is adjustable via an internal jumper connector for mic level, ifb level or line levels.
Line level ------------------------- 0.0 dBu at 600 ohms
Clear-Com IFB level ------------ -15 dBu at 200 ohms
Microphone level ----------------- -55.0 dBu at 20 ohms
To set channel 1 for the desired level:
Find jumper block JP100 on the circuit board.
Move the jumper so that it connects the pair of jumper pins labeled
with the desired level (Line, IFB, or Mic).
To set channel 2, repeat the above procedure using JP200.
