WIRING CONNECTIONS

ASK-4   #304 is a four zone audio monitoring system 
designed for direct connection to a DVR, PC soundcard or
IP Network Camera.  Model IF-4 Interface Adapter (usually 
mounted near the recording device) receives the wiring from 
the Verifact™ A Microphone, supplies power and drives the 
audio signals into the DVR, IP Network Camera, Video 
Server or PC Soundcard.  

 Distance between the Verifact   A Microphone and Model IF-
4 Interface Adapter may be up to 1,000 ft.(305m) using 
recommended wiring. Each output of the IF-4 has an audio 
level control to increase or decrease the level of audio output 
going to the receiving device.

MICROPHONE CONNECTIONS

Located at the bottom of the Verifact   A microphone is a 3-pin terminal block marked A, B, and C.

A = 12Vdc power 
B = Audio output of microphone
C = Ground

If using the recommended wiring (West Penn 452), connect as follows;

Red wire goes to terminal A of microphone
Black wire goes to terminal B of microphone
Bare wire goes to terminal C of microphone

After all microphones have been connected, bring the other end of the cable to the IF-4 location and connect each 
microphone to the corresponding terminal block of the unit matching A to A, B to B, and C to C. Be sure to properly match 
wire colors. If using cable from other manufacturers, color code may vary.

CONNECTIONS BETWEEN IF-4 AND DVR (OR OTHER AUDIO RECEIVING DEVICE)

Connect the RCA  outputs of the IF-4 to the corresponding audio inputs of the receiving device. RCA and RCA to 3.5mm 
mono cables are included in the kit.
