Mic/Line EQ Section
8. HIGH This control can boost or cut the high frequencies (centre 12kHz)
by ±15dB (12 o’clock position is zero)
9. FREQ This control sweeps the frequency band affected by the MID
control with centre frequency from 100Hz through to 8kHz
10. MID This control can boost or cut the mid frequencies set using the
FREQ control by ±15dB (12 o’clock position is zero)
11. LOW This control can boost or cut the low frequencies (centre 80Hz)
by ±15dB (12 o’clock position is zero)
Stereo Line Input Section
12. LINE L/MONO Connect a balanced or unbalanced line level signal to this 6.3mm
TRS jack input. Wired as follows.
13. LINE R For stereo line inputs, use this connector for Right input and the
above connector for Left input. All following channel controls will
affect both signals but Left & Right signals will remain separate.
14. ST1/PC Switches the channel input between ST1 and the PC interface
Press this switch in to override the ST1 inputs and the channel
will be fed from a PC or Mac connected to the USB B connector.
13. ST2/MPR Switches the channel input between ST2 and the MPR player.
Press this switch in to override the ST2 inputs and the channel
will be fed from playback of USB or SD media via the MPR.
14. GAIN control This control trims the mono or stereo input to the optimum level for the channel strip.
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.
The SIG and CLIP LEDs above the rotary control give an indication of the signal level.
Ideally, the Gain rotary control should be adjusted so that the green SIG LED is lit and
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.
Balanced Tip = Ring = Signal – Sleeve = Ground
