CONTROLS & CONNECTIONS
MONO INPUTS
Direct Out (switchable)
For connection to external multitrack
recorders or effects units.
Mic Input
A balanced female XLR connector accepts
balanced or unbalanced mic signals. At
-128dbu EIN the mic amp is extremely quiet
and transparent.
Line Input
A balanced 1/4" jack for connecting balanced
or unbalanced electronic instruments, such as
keyboards.
Insert
For patching in compressors or additional EQ
or for other signal processors. It can also be
used for recording.
Gain
A rotary gain control on each input alters the
gain of the input signal, from +5 to +60dB.
Linear circuitry within the preamp delivers
smooth gain control over the entire gain
range.
Filter Section
A high pass filter with an 18dB per octave
slope can be used to reduce frequencies
below 100Hz. Ideal for reducing unwanted
stage rumble or popping from microphones.
EQ Section
Equalisation is split into three bands. The HF
control provides 15dB of cut or boost (gain
adjustment) for frequencies above 12kHz. Two
swept mid frequency controls enable
frequencies from 240Hz to 6kHz to be
adjusted, offering 15dB of cut or boost at the
selected frequency. Signals below 60Hz can be
adjusted with the LF control, which features
±15dB of gain adjustment (cut or boost).
Auxiliary Section
For sending separate monitor mixes in live
applications, four aux busses, with two pre-
fade and two post-fade aux sends on each
input channel cater for all requirements.
Pan, Muting, PFL & Direct Pre
The pan control positions each channel’s signal
across the stereo image, with a mute button
to cut the signal completely. A PFL (Pre Fade
Listen) button solos the signal for monitoring.
The Direct Pre button selects the direct
outputs to be pre-fader.
Faders and Metering
Each mono channel features a smooth
100mm fader, a signal LED to show whether
a signal is present and a peak level LED
indicating signal levels in excess of +17dBu.
STEREO INPUTS
Input Connectors
The stereo inputs are connected via balanced
1/4" jack inputs delivering optimum
performance with other professional audio
equipment.
Stereo Returns
Stereo returns for effects processors are via
RCA phono inputs – these returns can also be
used with CD players and other hi-fi
equipment.
EQ Section
Equalisation on the stereo channel strip is
simpler than the EQ featured on the mono
channels. There are two controls, adjusting
HF signals at 12kHz and LF signals at 60Hz
by ±15dB.
Auxiliary Section
With 4 aux sends on the stereo input channels,
the signal can be sent pre-fade for use in a
monitor mix (using aux sends 1 & 2) or sent
post-fade (via aux sends 3 & 4) for effects
processing.
Bal, Muting, PFL & Direct Pre
The balance control adjusts the amount of
the signal sent to the left and right busses.
Mute and PFL buttons operate as on the
mono input channels, cutting or soloing the
stereo channel. With PFL pressed, the pre-
fade signal is fed to the headphones, control room output and
meters, with levels displayed on the left and right meters in
mono to enable levels to be monitored without interruption to
the main mix.
Faders and Metering
Each stereo channel features a smooth 100mm fader, a signal
LED to show whether a signal is present and a peak level LED
indicating signal levels in excess of +17dBu.
RETURNS CONTROLS
Gain Control
Positioned at the top of each stereo channel strip, adjusts
the gain
for each stereo return, with a peak signal LED indicating
when the signal exceeds +17dBu.
Return Master
Adjusts the overall level of the stereo returns in the main mix.
Mute Button
When stereo returns are used to return a signal from an
effects unit, the mute button offers a fast method of
comparing your mix with or without FX.
CONNECTOR PANEL
MASTER SECTION
Phantom Power
Global control over phantom power is
offered via a push button. When active, an
LED will illuminate.
2-Track Inputs
2-track recorder playback inputs are on
unbalanced RCA phonos.
Monitor Output and Mix Insert
Available on balanced 1/4" jacks.
Mix Outputs and Mono Sum
The main left and right mix outputs are
provided on balanced XLR connectors with a
mono sum signal available on a balanced 1/4"
jack.
Playback Level
The playback gain control adjusts the level
from the 2-track playback inputs. This
playback signal can be monitored separately
by pressing the PFL button, which routes it
to your monitoring system or to the
headphones, replacing any existing
monitoring signals. The ‘P/B Replace Mix’
button routes the playback signal directly to
the main mix, replacing any signal that may
be present.
Mono Sum, Monitor & Phones Level
Levels sent to the mono sum output,
monitor output and headphones can be
adjusted using these three rotary controls.
And when a pair of headphones are plugged
into the phones socket at the bottom right
of the mixer, the monitor outputs are cut for
easier headphone listening.
Auxiliary Masters
The aux output contains a mix of the aux
send signals sent from each input channel,
which can then be sent as a monitor mix to
stage loudspeakers or to send to an
external effects unit.
Each aux bus features a master level control,
with an AFL (After Fade Listen) button
enabling monitoring of each aux output.
When pressed, the AFL button routes the
aux output to the monitor ouputs or to the
headphones, where it can be monitored on
the master stereo meters.
Faders and Metering
Controlling the overall stereo mix level are
two 100mm faders, with two 12-segment 3-
colour LED peak-reading bargraph meters
monitoring the mix right and mix left
outputs. These meters normally follow the
current monitor selection, so if any PFL or
AFL is pressed, the meters will switch to
monitor this and the Solo AFL/PFL LED will
light.
