Mic Gain Adjustment

Adjusting the microphone gain

According to JTSO approval C58a, the microphone output voltage is factory- preset to 400 mV. If the microphone output voltage is too high or too low for your intercom system, it can be re-adjusted on the microphone. To do so, use a small slotted screwdriver and

turn the ‘Mic Gain Adjustment’ screw (see illustration on the left) until you have reached the desired setting.
