Each mono input channel offers a balanced microphone
input via the XLR connector and also features switchable
+48 V phantom power supply for condenser microphones.
The MX preamps provide undistorted and noised-free gain
as is typically known only from costly outboard preamps.
Each mono input also features a balanced line input on a
1/4
"
connector . Unbalanced devices (mono jacks) can also
be connected to these inputs.

to check recorded signals via monitor speakers or headphones.
Similarly, the ALT 3-4 switch routes the signal from the
Alt 3-4 bus to the same path for monitoring purposes.
The MAIN MIX switch sends the main mix signal to the above-
mentioned outputs and to the level metre.

please remember that you can only use either the

one time. You can never use both simultaneously!
The mono channels of the mixing consoles have a high-slope
LOW CUT filter for eliminat ing unwanted, low-frequenty signal
components (75 Hz, 18 dB/octave).
LOW CUT
TRIM
Use the TRIM control to adjust the input gain. This control
should always be turned fully counterclockwise whenever you
connect or disconnect a signal source to one of the inputs.
All mono input channels include a 3-band equalizer. All bands
provide boost or cut of up to 15 dB. In the central position, the
equalizer is inactive.
2.1.3 Aux sends
The circuitry of the British EQs is based on the technology
used in the bast-known top-of-the-line consoles and providing
a warm sound without any unwanted side effects. The result are
extremely musical equalizes which, unlike simple equalizers,
cause no side effects such as phase shifting or bandwidth
_
limitation, even with extreme gain settings of +15 dB.
The upper (HI) and the lower band (LO) are shelving filters
that increase or decrease all frequencies above or below their
cut-off frequency. The cut-off frequencies of the upper and
lower band are 12 kHz and 80 Hz respectively. The mid band is
configured as a peak filter with a centre frequency of 2.5kHz
Aux sends take signals via a control from one or more channels
and sum these signals to a so-called bus. This bus signal is sent
to an aux send connector and then routed, for example, to an active
monitor speaker or an external effects device. The return from an
external effect device can then be brought back into the console
via the aux return connectors.
For situations which require effects processing, the aux sends are
usually switched post-fader so that the effects volume in a channel
corresponds to the position of the channel fader. if this were not the
channel would remain audible even when the fader is turned to zero.
When setting up a monitor mix, the aux sends are generally switched
to pre-fader, i.e. they operate independently of the position of the
channel fader.
Both aux sends are mono, are sourced after the equalizer and
offer up to +15dB gain.
PFL
SOLO
Also a rule, solo signals are monitored via the control room
output and headphones connector and are displayed by the
level meters. If a also switch is pressed, the signals from the
tape input, Alt 3-4 and main mix are blocked from the control
room outputs, the headphone connector and the level meter.

The high-procision level meter accurately displays the

When recording to a digital device, the recorder

system stabilization.
Please do not connect microphones to the mixer
(or the stagebox/wellbox) while the phantom power
supply is switched on. Connect microphones before
you switch on the power supply. In addition, the
monitor/PA loudspeakers, should be muted before
you activate the phantom power supply. After
switching on, wait approx. One minute to allow for
When recording to an analog device, the VU meters of the
recording machine should reach approx. +3 dB with low-
frequency signals (e.g. Kick drum). Due to their inertia VU
meters tend to display too low a signals level at frequencies
above 1 kHz. This is why ,for example, a Hi-Hat should only
be driven as far as -10dB. Snare drums should be driven to
approx. 0 dB.
To activate the PFL function, depress the MODE switch. The
PFL function should, as a rule, be used for gain setting purposes.
The signal is sourced pre-fader and assigned to the mono PFL
bus. In the
“
PFL
”
setting, only the left side of the peak meter
operates. Drive the individual channels to the 0 dB mark of the
VU meter.
When the MODE switch is not depressed, the stereo solo bus
is activate. Solo is short for
“
Solo In Place
”
. This is the customary
method for listening to an individual signal or to a group of signals.
As soon as a solo switch is pressed, all channels in the control
room (and headphones) that have not been selected are muted
thereby retaining stereo panning. The solo bus can carry the
output signals of the channel pan controls, the aux sends and
the stereo line inputs. The solo bus is, as a rule, switched post-
fader.
MODE
The MODE switch determines whether the channels

switch operates as PFL (Pre Fader Listen) or as solo (Solo In
Place).
The PAN control in the channel strip offers a constant
power characteristic. This means that the signal is
always at a constant level, irrespective of its position
in the stereo panorama. If the PAN control is moved
fully left or right from center, the level increases by 4
dB in that channel. This signal is not louder. For this
reason, with the solo function activated (Solo In Place),
audio signals from the channels with PAN controls that
have not be moved fully to the left or right are displayed
at a lower volume that in the PFL function.

If you press the MUTE/ALT 3-4 switch, aux send 1
is muted, provided that it is switched post-fader.
However, this does not affect the aux send 2
Aux send 1 can be switched pre-fader and is thus particularly
suitable for setting up monitor mixes.

When the PRE switch is pressed, aux send 1 is sourced
pre-fader.
The aux send labeled FX is for sending to effects devices and
is thus set up to be post-fader.

If you wish to use the internal effects processor, the
STEREO AUX RETURN 2 connectors should not be is

You can also connect an external effects processor to
