Louroe Electronics ASK-4 101DV - Manual (Page 3)

SENSITIVITY SWITCH OF VERIFACT D-V 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 1kW )
L represents low sensitivity (-6dB output into 1kW )
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 #101-DV WITH A DVR OR PC SOUNDCARD
The APR-1 Audio Base Station of ASK-4 101-DV is compatible with all commercial DVR’s and PC
Soundcards that accept line level input (0dB@600W
). An RCA cable is included with the kit for connecting
Audio Out to Audio In 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 mono 3.5mm plug.
PC soundcards contain a standard 3.5mm stereo Audio Input or Line Input. Do not use Mic Input of
soundcard. Louroe microphones are line level (0dB@600W
) and will overdrive the Mic Input. Use “Audio
Input” or Line Input” of the soundcard.
