STEREO INPUT CHANNEL
STEREO INPUTS
Each Stereo Input section comprises a pair of similar inputs. The inputs are
electronically balanced and separate 3-pole ‘A’ gauge (TRS) jacks are pro-
vided for the Left and Right source signals. A mono signal may be plugged
into the upper (left) socket only and will be fed equally to both paths.
GAIN
This knob allows you to match the input level to suit a wide variety of pro-
fessional, semi-professional and hi-fi sources.
Start with a low setting, especially for professional equipment, and increase
it if you cannot reach an adequate signal level with the fader at the nominal
`0’ mark. See `Setting Up & Troubleshooting’ on page 10 to learn how to
set GAIN correctly.
EQUALISER
The Equaliser(EQ) comprises three sections.
HF EQ
The upper control provides H.F. (treble) boost and cut of 15dB at 12kHz.
Turning to the right provides boost, adding crispness to drum machines,
synths and electronic instruments. Turning to the left cuts the same fre-
quencies, reducing hiss or excessive brilliance.
MID EQ
The MID control provides cut and boost of 15dB, at a 1kHz.
LF EQ
The lowest knob is an LF (bass) section providing boost and cut of 15dB at
80Hz. Turning to the right provides boost, adding extra punch to synths,
guitars or drums. Turning to the left can be helpful to reduce hum or
boominess or to improve a mushy sound.
Set the controls to the centre-detented position when not required.
AUXILIARY SENDS
These are used to set up separate mono mixes for FOLDBACK, EFFECTS
or recording, and the combination of each Aux Send is mixed to the respec-
tive Aux Output at the rear of the mixer. For Effects it is useful for the sig-
nal 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 1 is always PRE-FADE, POST-EQ, for typical use as a monitor or fold-
back feed. Aux 2 is normally POST-FADE, POST-EQ for use as an effects
send.. By pressing the AUX 2 PRE switch on the Master section the Aux 2
send is set PRE-FADE, POST-EQ. Both knobs should be turned down
when not in use.
8
LEX FX
This control routes the post-fade, post-EQ channel signal to the Lexicon FX
bus, which feeds the internal LEXICON Digital Effects Processor. The knob
should be turned down when not in use. The output of the LEXICON unit
feeds the Stereo Mix directly or may be mixed to the Aux 1output (see
Master section, no. 4).
BALANCE
The BAL (Balance) control determines the position of the signal within the
stereo mix image. Rotation fully anticlockwise feeds the signal solely to the
Left mix bus, while rotation clockwise sweeps the image to the Right bus.
PFL
When the latching PFL switch is pressed, a mono sum of the pre-fade, post-
EQ signal is fed to the headphones and meters, where it replaces the Stereo
Mix as the normal monitor source. The PFL ACTIVE LED on the Master
section illuminates to warn that the headphones and meters are now carry-
ing a PFL signal. This is a useful way of listening to any required input signal
without interrupting the main mix, for making adjustments or tracing prob-
lems. The monitors and meters revert to stereo Mix when the PFL switch
is released.
CHANNEL FADER
The 60mm FADER allows precise balancing of the various source signals
being mixed to the Master Section. You get most control when the input
Sensitivity is set up correctly, giving full travel on the fader. See the `Setting
Up & Troubleshooting’ section on page 10 for help in setting a suitable sig-
nal level.
