SENSITIVITY SWITCH OF VERIFACT   D 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

W

)

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

W

)

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® #102-RM WITH A DVR OR PC SOUNDCARD 

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

W

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

Audio Out

 to

 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
