CXM User manual 5
1.07 Equalisation
The three equalisation (or EQ) controls will alter the tone of the audio passing through
the channel. It is not normal to assume that all three controls need to be rotated off
their centre detented position at the same time. More so, if all three controls are
rotated clockwise, then a previously optimised gain setting, could still produce overload
and distortion at the boosted high, middle and low frequencies. Excessive EQ
adjustment for any pre-recorded material should be avoided, what is more, if large
amounts of EQ are needed to produce normal listen quality then the user should check
the condition of ancillary equipment (eg. damaged turntable cartridge, dirty tape
machine playback heads) or even faulty audio wiring.
1.07a HF - High Frequency
This control can be used to make adjustment to the treble content of the music signals,
a centre detent is provided, with clockwise movement to boost treble, and anti-
clockwise to reduce treble.
1.07b MID - Middle
Use this control to adjust the middle frequency content of the music, operation is
identical to the HF control. Rotating this control towards the left will have the effect of
reducing the harshness of the audio input signal.
1.07c LF - Low Frequency
This adjusts the bass content of the music signals, again with centre detent and similar
operation to the HF control.
1.08 PFL - Select (Pre-Fade Listen)
This switch routes the pre-fade signal (not controlled by the fader), to the PFL display
on the master module and to the headphone amplifier. The switch will automatically
cancel previous selections and two or more can be selected simultaneously.
1.09 Start Switch
When connected to suitable equipment, this switch can be used to start turntables, CD
players and tape decks etc.
1.10 Peak LED
This red LED is used to indicate that the channel has reached or is very close to the
threshold of distortion. The gain control must be reduced and set in accordance with
1.02.
1.11 AUX 1 and AUX 2 - Auxiliary Sends
The auxiliary send controls provide a useful, flexible output facility that can be used to
interface a variety of units for signal processing, such as sampling or digital delay
effects.
They can also be used as a flexible extra output facility. Unless configured differently
by the installation engineer, the factory settings for the Aux outputs are:-
AUX 1 is normally configured to operate with pre-fade signals (i.e. signals not
controlled by the fader).
AUX 2 is normally operated in the post fade mode (i.e. signals are controlled by the
fader.
