The INPUT B switch disconnects the
main XLR input from the channel and
replaces it with the second (B) input.
The B input is also an XLR but it is
normalled through a ¼ inch jack
socket which provides a input for
signals which require protection
against accidental 48 volt connection.
All inputs can be used for Mic or Line
level signals and the input B switching
facility provides an easy way to
activate a back up source for critical
The PHASE switch activates a 180
degrees phase change within the input
amplifier.
The TREBLE (dual concentric top)
control gives continuous adjustment of
boost and cut from + 15dB to - 15dB
with a 0dB centre detent.
The treble FREQ. (dual concentric
bottom) control gives continuous
adjustment of the frequency range that
the treble equaliser acts on from 2K to
20K. The treble equaliser has a
shelving response.
The hi mid WIDTH control gives
continuous adjustment of bandwidth
from 0.1 to 2 octaves with a 0.4 octave
centre point.
The lo mid WIDTH control gives
continuous adjustment of bandwidth
from 0.1 to 2 octaves with a 0.4 octave
centre point.
The BASS (dual concentric top)
control gives continuous adjustment of
boost and cut from + 15dB to - 15dB
with a 0dB centre detent.
The bass FREQ. (dual concentric
bottom) control gives continuous
adjustment of the frequency range that
the bass equaliser acts on from 20Hz
to 200Hz. The bass equaliser has a
shelving response.
The insert PRE switch arranges the
input channel signal to pass through
the equaliser before the insert point
when activated and after the insert
point when not activated.

The 48V switch connects 48 volt
phantom power to both of the XLR
input connectors. This is suitable for a
condenser microphone or DI box.
The GAIN control gives continuous
adjustment of the input amplifier gain
from + 15dB to + 60dB.
The PAD switch gives 30dB of
attenuation to the input signal which
will allow the connection of high
output microphones or line level
signals. If the input amplifier is
transformer coupled (option) the pad
greatly reduces the risk of saturation at
very low frequencies.
The hi mid FREQ. (dual concentric
bottom) control gives continuous
adjustment of the frequency range that
the hi mid equaliser acts on from
400Hz to 8K.
The HI MID (dual concentric top)
control gives continuous adjustment of
boost and cut from + 15dB to - 15dB
with a 0dB centre detent.
The LO MID (dual concentric top)
control gives continuous adjustment of
boost and cut from + 15dB to - 15dB
with a 0dB centre detent.
The lo mid FREQ. (dual concentric
bottom) control gives continuous
adjustment of the frequency range that
the lo mid equaliser acts on from
100Hz to 2K.
The EQ switch connects the equaliser
in the input channel signal path.
The HI PASS filter control is
continuously adjustable from 20Hz to
400Hz.
The HI PASS switch connects the filter
in the input channel signal path before
the insert point and equaliser.
