APPLYING POWER TO IF-1
A 12 Vdc AC Adapter is included with the IF-1. First connect small plug into 12 Vdc power jack on input side of IF-1.
Connect other end (power block) to standard 110V/120 Vac electronic outlet or power strip.
“AUDIO OUT” CONTROL OF POTENTIOMETER
Located on the IF-1 input side (next to 3-pin microphone terminal block) is a potentiometer for audio gain
adjustment. Occasionally, though rare, the microphone may overdrive (or underdrive) the audio signal into the IF-1.
Should this occur, use a small screw driver and move arrow clockwise to increase gain. Move counterclockwise to
lower gain. The potentiometer is positioned straight up at the factory.
