1. MONITOR OUTPUT - Connect headphones to listen
to the audio that is supplied to the transmitter. The
monitored level will vary with the level of the incoming
audio, the setting of the INPUT LEVEL control, and the
setting of the MONITOR OUTPUT level control.
2. MONITOR OUTPUT LEVEL Control - With the INPUT
LEVEL control set properly, adjust this control for a
comfortable listening level in the connected monitor
headphones.
3. INPUT LEVEL Control - This control is used to adjust
the input sensitivity. For a monaural audio input signal,
set this control at or just below the point where the
(OVER) MODULATION LED indicators light on audio
peaks. For a stereo input signal, set this control at or
just below the point where either of the (OVER)
MODULATION LED indicators light on audio peaks.
4. (OVER) MODULATION Indicators - These indicators
light to aid in the setting of the INPUT LEVEL control for
proper modulation. They light to indicate that full
modulation is being reached when the rear panel
LIMITING/COMPRESSION switch (see rear panel Item
4) is set to "OFF". With the switch set for either the "L"
or "C+L" position, these indicators will light on audio
signal peaks as the limiter is activated at full modula-
tion. Also see rear panel Item 4 for additional hints for
proper setting of the LIMITING/COMPRESSION switch
for a given type of audio source. Set the INPUT LEVEL
control at or just below the point where the (OVER)
MODULATION indicators light on audio peaks.
