SENSITIVITY SWITCH OF VERIFACT    C  MICROPHONE

For special installations that require less microphone sensitivity or where there is background noise, a sensitivity switch is 
mounted to the microphone pre-amp (PC Board) and has two positions, N and L:

N represents normal sensitivity (0dB ouput into 1k

)

L represents low sensitivity (-6dB output into 1k

)

Louroe VERIFACT™ microphones are always shipped with the sensitivity switch in normal (N) position. Do not change 
unless necessary. To change the sensitivity setting, use a small screwdriver and move slide switch from N to L position.  
The switch is mounted on the back side of the microphone housing.

NOTE REGARDING INTERFACING ASK-4 #101C WITH A DVR OR PC SOUNDCARD 

The APR-1 Audio Base Station of ASK-4 #101C is compatible with all commercial DVR’s and PC Soundcards 
that accept line level input (0dB@600

 or higher).  An RCA cable is included with the kit for connecting 

Audio

 of DVR.  If DVR’s audio input is a 3.5mm jack, an RCA to 3.5mm adapter (not supplied) must 

be attached to the plug that connects to DVR’s 

Audio Input

.  Check with DVR’s specifications to determine if 

the audio input requires a 

stereo

 or
