STEREO INPUT CHANNELS
Each stereo input channel comprises two pairs of inputs per channel strip:
1
INPUTS STE-1/2/3/4
These inputs accept 3-pole `A’ gauge (TRS) jacks. Use these inputs for sources such as
keyboards, drum machines, synths, tape machines or processing units. The inputs are
BALANCED for low noise and top quality from professional equipment, but you can use
UNBALANCED sources by wiring up the jacks as shown in the “Wiring it Up” section
earlier in this manual, although you should then keep cable lengths as short as
possible. Mono sources may be used by plugging into the left jack only.
2
GAIN
The GAIN control sets the level of the channel signal.
3
RETURNS RET-1/2/3/4
These inputs are unbalanced on RCA phono connectors, and are intended for use with
CD players, DAT machines or Hi-Fi equipment. Alternatively they may be used as simple
effects returns or stereo instrument inputs.
4
GAIN
The GAIN control sets the input level to the channel, allowing matching to a wide
range of line level sources.
5
EQUALISER
HF EQ
Turn to the right to boost high (treble) frequencies, adding crispness to percussion
from drum machines, synths and electronic instruments. Turn to the left to cut these
frequencies, reducing hiss or excessive brilliance. Set the knob in the centre-detented
position when not required. The control has a shelving response giving 15dB of boost
or cut at 12kHz.
LF EQ
Turn to the right to boost low (bass) frequencies, adding extra punch to synths, guitars
and drums. Turn to the left to reduce hum, boominess or improve a mushy sound. Set
the knob to the centre-detented position when not required. The control has a shelv-
ing response giving 15dB of boost or cut at 60Hz.
6
AUX SENDS
These are used to set up a separate mixes for FOLDBACK, EFFECTS or recording, and the
combination of each the Aux Send is mixed to the respective Aux Output at the rear of
the mixer. For Effects it is useful for the signal to fade up and down with the fader
(this is called POST-FADE), but for Foldback or Monitor feeds it is important for the
send to be independent of the fader (this is called PRE-FADE).
AUX SENDS 1 AND 2
These are always PRE-FADE and therefore most appropriate for foldback or monitor
mixes or external submix.
AUX SEND 3 AND 4
These are always POST-FADE for effects sends, external submix (or for centre Voice
cluster or mono Tape mix.
7
BALANCE
This control sets the amount of the channel signal feeding the Left and Right MIX or
SUB buses, allowing you to balance the source in the stereo image. When the control
is turned fully right or left you feed only that side of the signal to the mix. Unity gain
is provided by the control in the centre-detented position.
8
MUTE
All outputs from the channel are enabled when the MUTE switch is released and muted
when the switch is down.
