The M175DC transmitter features a wide range input
limiter to guard against overload distortion and allow
maximum signal to noise ratio. The following procedure
will adjust the wireless system to take full advantage
of the limiter action to prevent excessive output level
from the receiver from overloading the recorder. This
will also maximize the signal to noise ratio of the audio
being recorded.
Note: This procedure assumes the receiver is
connected to an antenna and output connector
in the same configuration and under the same
load conditions that will be experienced in real
operating conditions.
1. Install battery in transmitter and attach microphone
and set transmitter MIC LEVEL Adjustment to near
maximum clockwise position.
2. Turn on transmitter and place microphone near a
sound source, such as a portable radio.
3. Ensure the receiver’s Power and Code LED indica­
tors are glowing.
4. With the sound source (your portable radio) set
between stations, adjust its volume so that the 0 dB
Modulation LED on the receiver flickers slighty.
5. Leave the portable radio running and adjust the
receiver’s Audio Output Level Control so that the
audio input to the recorder is just below the maxi­
mum that the recorder can handle.
