Monitor and effects busses (Aux sends)

Fig. 4.3 Aux Send control
Monitor and effects busses (AUX sends) source their
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 (for monitoring applications:
MON OUT) and then routed, for example, to an active
monitor speaker or external effects device. In the latter
case, the effects return can then be brought back into
the console via the aux return connectors.
All monitor and effects busses are mono, are tapped into
post EQ and offer amplification of up to +15 dB. Use the
AUX controls to add the channel signals to the send
way.
Pre-fader/post-fader
When using effects on a channel signal, it is usual to
have the aux send post fader so that the balance
between effect and dry signal stays constant even when
the channel fader is altered. lf this were not the case, the
effects signal of the channel would remain audible even
when the channel fader is turned all the way down. For
monitoring, the aux sends are generally pre-fader, i.e.
they operate independently of the position of the channel
fader.
When the PRE switch is pressed down, the associated
aux send is taken pre-fader.
The MON monitor way (model LMC-2022FX) is preset to
pre-fader.
DSP control
The aux send marked DSP offers a direct route to the
built-in effects processor and is therefore post-fader and
post-mute. Please refer to page 36 for detailed
information on the effects processor.
Notes
Models LMC-2642FX and LMC-3242FX: If you
are using the built-in effects processor, make sure that
STEREO AUX RETURN 3 has nothing plugged into it,
otherwise the internal effects return will be muted. This is
not relevant if you use the FX OUT jack to drive an
external effects device.
Model LMC-1422FX and LMC-2022FX: On these
consoles, the above note refers to the STEREO AUX
RETURN 2 jacks as these models do not have a
dedicated effect output.
Channel fader, PAN, MUTE and SOLO

Panorama control
The PAN control determines the position of the channel
signal within the stereo image. When working with
subgroups, you can use the PAN control to assign the
signal to just one output, which gives you additional
flexibility in recording situations.
MUTE switch
The MUTE switch breaks the signal path pre-channel
fader, hence muting that channel in the main mix. The
aux sends which are set to post-fader are likewise muted
for that channel, while the pre-fader monitor paths
remain active irrespective of whether the channel is
muted or not. The adjacent LED will light when mute is
engaged.
Clip LED
This LED lights up when the input signal is driven too
high. If this happens, back off the GAIN control and, if
necessary, check the setting of the channel EQ.
SOLO
switch
The SOLO switch is used to route the channel signal to
the solo bus (Solo In Place) or to the PFL bus (Pre
Fader Listen). This enables you to listen to a channel
signal without affecting the main output signal. The
signal you hear is taken either before the pan control
(PFL, mono) or after the pan and channel fader (Solo,
stereo).
SUB (1-2, 3-4) routing switch
The SUB switch routes the signal to the corresponding
subgroups. The LMC-2642FX and LMC-3242FX have 4
subgroups (1-2 and 3-4) each.
MAIN routing switch
The MAIN switch routes the signal to the main mix bus.
Channel fader
The channel fader determines the channel's volume in
the main mix (or submix).
