WIRING CONNECTIONS
ASK-4 #304 is a four zone audio monitoring system
designed for direct connection to a DVR, PC soundcard or

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.
