Stereo Input Channels

1 - INPUT JACKS
Stereo 1 input accepts 3-pole 'A' gauge (TRS) jacks and Stereo 2 input accepts RCA jacks.
Use these inputs for sources such as keyboards, drum machines, synths, tape machines
or returns from processing units. Stereo 1's TRS is BALANCED for low noise and top quality
from professional equipment, but you can use UNBALANCED sources by wiring up the jacks
as shown in 'Connecting Leads' section, although you should then keep cable lengths as
short as possible to prevent 'hum' being induced into the sound system. Mono sources may
be used by plugging into the left jack only. Stereo 2's RCA connectors are for UNBALANCED
sources.
2 - GAIN
The GAIN control sets the input level to the channel, allowing matching to a wide range of
line level sources.
3 - EQUALISER
HF EQ
Turn clockwise to boost high (treble) frequencies, adding crispness to percussion from
drum machines, synths and electronic instruments. Turn anticlockwise to cut these frequen-
cies, reducing hiss or excessive brilliance. Set the knob in the centre-detented position
when not required. The control has a shelving response giving 15 dB of boost or cut at 12
kHz and above.
LF EQ
Turn clockwise to boost low (bass) frequencies, adding extra punch to synths, guitars and
drums. Turn anticlockwise to reduce hum, boominess or improve a mushy sound. Set the
knob to the centre-detented position when not required. The control has a shelving re-
sponse giving 15dB of boost or cut at 60Hz and below.
4 - AUX SENDS
These are used to set up separate mixes for FOLDBACK, EFFECTS or recording, and the
combination of each Aux Send is mixed to the respective Aux Output at the rear of the
mixer. The sends are always PRE-FADE which is most appropriate for Foldback or Monitor
feeds, but note that the Line Inputs on pairs of Mono channels may be used as alternative
stereo inputs if post-fade sends are essential for effects.
5 - LEVEL
The rotary level control adjusts the overall level of the signal which is fed to the Mix or
selected pair of Groups.
6 - ROUTING
The Stereo channel signal is fed either to a pair of Subgroups (switch UP) or the stereo Mix
(switch DOWN), at a level set by the LEVEL control. Stereo 1 feeds to Subgroups 1 & 2,
Stereo 2 feeds to Subgroups 3 & 4.
7 - PFL
When the latching PFL switch is pressed, the pre-fade, post-EQ signal is fed in mono to
the headphones, control room output and meters, where it replaces the selected monitor
source. The PFL/AFL LED on the Master section illuminates to warn that a PFL is active.The
Left and Right meters display the PFL signal in mono.
