Input gain (sensitivity) control
(1)
This important control allows to adjust the transmitter’s audio input gain to various micro-
phones or instruments.
Setting input gain for microphones / instruments
A proper adaptation of the transmitter’s input gain to the output level of the sound sour-
ce is very important for obtaining the best signal-to-noise-ratio. Whenever a new setting
has to be done, it should be done
before
the wireless system is connected to an amplifier
to avoid annoying feedback surprises:
- turn both transmitter and receiver on
- set the gain control screw (1) on the transmitter in a position, where
the green ‘o.k.’ LED (12) on the transmitter is continuously lit when an
average audio signal level is applied to the transmitter, either by
speaking into the microphone or by playing a connected instrument at
normal output level. At loud passages, the red ‘clip’ LED (13) should
just
not
become lit.
- the ‘mute’ noise suppression control (9) on the receiver has been pre-
adjusted in the factory for best noise performance. Only if problems
should occur, such as noise bursts or drop-outs, the ‘mute’ control
should be readjusted following the instructions given on page 23.
