OUTPUT SIDE OF IF-1 TO AUDIO RECEIVER (DVR, IP Network Camera, etc.)

(A) If audio receiver is a DVR or VCR that has RCA input, use the single RCA cable to connect RCA output

of IF-1 to “Audio In” of DVR/VCR.

(B) If the audio receiver (DVR, Soundcard, etc.) has a 3.5mm stereo input, use the 3.5mm stereo cable

and connect to the 3.5mm stereo jack of the IF-1 before connecting to the “Audio In” or “Line In” of the
DVR or soundcard. NOTE: DO NOT connect to “Mic In” of soundcard.

© If audio receiver (IP Network camera, DVR, Video Server, etc.) has a 3.5mm mono input, connect the

RCA to 3.5mm mono cable to the RCA audio out of IF-1 to the “Audio In” or “Line In” of IP Network
camera, etc.

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.
