SENSITIVITY SWITCH OF MICROPHONE
For special installations that require less microphone sensitivity, a sensitivity switch has been added
to the microphone pre-amp (PC board) and has two positions - N and L:
N represents normal sensitivity (0dB output into 600W)
L represents low sensitivity (-6dB output into 600W)
NOTE: Louroe™ Verifact microphones are always shipped with the sensitivity switch in
normal (N) position. Do not change unless required.
To make an adjustment, use a small screwdriver and move slide switch from N to L. Sensitivity
switch is located on the backside of Verifact™ A Microphone.
OPERATION
With the addition of the MS-1 (Mute Switch), the microphone audio can be muted if not needed. Turn On the
rocker switch on the MS-1 to activated the audio of the microphone. The built-in red light on the switch will light
indicating that the microphone is live and audio is present at the IF-1. If the output of the IF-1 is connected to a
receiver such as a DVR, Video Encoder or IP Camera, audio is present on the input of these receivers.
Turning OFF the MS-1, will turn OFF the audio from the microphone and the built-in light on the switch is not
lighted.
