Mic /L ine Input Module
Input Stage
Two inputs are provided to the module, one microphone level input on an XLR
connector, and one line level on a 1/4" stereo jack. The MIC input has +48V
Phantom Power available for condenser microphones which may be activated by
setting an internal jumper on the circuit board.
A pre-EQ Insert Point is also provided for the addition of a limiter or other signal
processor to the input channel.

The
LINE switch selects the Line input when pressed and the Mic input when
released. An LED in the switch illuminates when the Line input is selected.
2
The
SENS (Sensitivity) control adjusts the level of the selected input, and
should be set up carefully to ensure a good signal to the rest of the mixer. If it is
set too high the signal will distort as it overloads the channel and causes clipping.
If it is set too low the level of any background hiss will be more noticeable and you
may not be able to get enough signal level to the output of the mixer.
Equalisation
3
The Equaliser (EQ) allows precise manipulation of the sound, particularly to
improve the sound of microphone sources where the original sound is often far from
ideal.
Three EQ bands are provided, giving 10dB of boost or cut at frequencies of 100Hz
(LF), 3.5kHz (MF) and 8kHz (HF).
4
The EQ may be switched in and out of circuit by the EQ switch. An integral
LED illuminates when the EQ is in circuit (switch pressed). Toggling this switch
on and off allows an instant comparison between the equalised signal and the
untreated signal.
5
An AUX feed is provided for use with an effects unit, reverb or as an additional
output from the mixer. The AUX control sets the send level from the channel, and
this is mixed with the signal from any other channels required before being sent to
the Aux Send output jack at an overall level set by the Master module AUX SND
control. The send from the channel may be selected as pre- or post fader by changing
the position of internal jumpers.
6
The
PAN control sets the amount of the channel signal feeding the Stereo Mix
output, either directly or via the A/B Crossfader (see Channel Output below),
allowing you to move the source smoothly across the stereo image. Turning the
control clockwise moves the source progressively to the right in the stereo image,
and turning the control anticlockwise moves the source to the left.
7
The large illuminated ON switch activates the channel when pressed, and mutes
the channel when released. If the Aux Send is selected as pre-fade, the ON switch
will not affect the Aux signal, but will mute it with the main channel output if
selected as post-fade.
