Channel Functions
1. MIC / Line input Connect a balanced microphone or line input to this XLRF input.
An unbalanced microphone or line signal can be connected by XLR
provided that +48V phantom power is not used. Wired as follows.
The Mic/Line input can also accept a 6.3mm balanced TRS or
unbalanced TS plug (jack plug). Phantom power does not affect
this connection. Wired as follows.
2.
Clip LED
The CLIP LED lights when the channel is being overloaded.
Ideally, the Gain rotary control (described below) should be adjusted so that the loudest
passages of the input signal (e.g. bass drum beats) will just momentarily trigger the
CLIP LED. Anything longer than a momentary flicker of the CLIP LED means that the
Gain should be reduced. Using the PFL button further down the channel strip gives a
more detailed view of the channel level on the main VU LEDs.
3. GAIN control This control trims the input signal to the optimum level for the channel strip circuitry.
Too low a signal level can result in a weak signal-to-noise ratio and too high can result
in overload and distortion in the signal output.
4. Stereo inputs The two right-most input channels on the console are stereo with
Left and Right 6.3mm jack inputs. Alternatively, a mono signal can be
connected to the Left input jack and the channel will effectively operate
as a mono channel.
EQ Section
5. HIGH This control can boost or cut the high frequencies (centre 12kHz)
by ±15dB (12 o’clock positi on is zero)
6. MID This control can boost or cut the mid frequencies (centre 2.5kHz)
b y ±15dB (12 o’clock posit ion is zero)
7. LOW This control can boost or cut the low frequencies (centre 80Hz)
by ±15dB (12 o’clock position is zero)
