S tereo Input Module
Input Stage
Two switched stereo inputs are provided to the module, one on 1/4" stereo jacks
and one on RCA phono plugs. The inputs would typically be used for CD players,
DAT machines or VTRs, and Line 1 input may also be reconfigured by changing
internal jumpers to provide RIAA equalisation for turntables. A remote start facility
is included for controlling turntables, CD players or other equipment.

The LINE 2 switch selects Line 2 input when pressed and Line 1 input when
released. An LED in the switch illuminates when the Line 2 input is selected.
2
The GAIN control trims the level of the selected input by +/-10dB to
compensate for different sources.
Equalisation
3
The Equaliser (EQ) allows correction of the sound, to enhance poor recordings
or compensate for different room acoustics. Since the sources which would
typically be connected to the stereo inputs will generally be of reasonable sound
quality, the EQ controls on these inputs have less range than the similar section on
the Mono input modules, giving more subtle control.
Three EQ bands are provided, giving 6dB 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
A mono 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 BAL (Balance) control pr/-6dB level adjustment for the signal
feeding the Stereo Mix output, either directly or via the A/B Crossfader (see Channel
Output below), allowing compensation for imbalance in the source signal.
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. Pressing the ON switch also provides an isolated contact
closure on the remote START phono socket to control external equipment.
8
The PEAK LED warns the DJ of excessive signal level in the channel before
distortion occurs. The signal is sampled just after the EQ section, and illumination
of the LED will indicate that the input gain is set too high, or that the EQ settings
are too extreme.
