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 1KW)
L represents low sensitivity (-6dB output into 1 KW)
NOTE: Louroe Verifact microphones are always shipped with the sensitivity switch in
normal (N) position. Do not change unless required.
Should an adjustment be necessary, locate the small red switch on the PC board mounted behind
the back side of the stainless face plate. Using a small tool, move the slide switch from N to L
