Louroe Electronics ASK-4 431 - Manual (Page 7)

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 1K? )
L represents low sensitivity (-6dB output into 1 K? )
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.
