Graphic equalizer (model LMC-2022FX)
LMC-2022FX
Fig. 4.19 Graphic 9-band equalizer
The graphic stereo equalizer allows you to tailor the
sound to the room acoustics.
EQ IN switch
Use this switch to activate the graphic equalizer.
MAIN MIX/MONITOR switch
This toggles the graphic equalizer between the main mix
and the monitor mix. With the switch up (not depressed),
the equalizer is active in stereo on the main mix, and
inactive on the monitor mix. When the switch is
depressed the equalizer is active in mono on the monitor
mix, and inactive on the main mix.
FEEDBACK DETECTION switch
The switch turns on the Feedback Detection System. lt
uses the LEDs in the frequency band faders to indicate
the critical frequencies. On a per-need basis, lower the
frequency range in question somewhat in order to avoid
feedback. The graphic stereo equalizer has to be turned
on in order to use this function.
At least one or several microphone channels have to be
open for feedback to occur at all. Feedback is
particularly
common
when
stage
monitors
are
concerned, because monitors project sound in the
direction of microphones. Therefore, you can also use
the Feedback Detection for monitors by placing the
equalizer in the monitor bus ( MAIN MIX/MONITOR
switch).
Digital effects processor
All models
Fig. 4.20 Multi-effect processor
Here you can find a list of all presets stored in the multi-
effects processor. This built-in effects module produces
high-grade standard effects such as reverb, chorus,
flanger, delay and various combination effects. Use the
Aux Send FX on the channels and the Aux Send FX
master control to determine the input signal of the effects
processor.
The built-in stereo effects processor has the advantage
that it does not need to be wired up. This excludes the
danger of humming or level mismatch right from the start
and thus considerably facilitates use.
These effect presets are classical "mixing effects". If you
move the STEREO AUX RETURN FX control, you mix
the channel signal (dry) and the effect signal. You can
control the balance between the two signals with the
channel fader and the STEREO AUX RETURN FX
control.
FX OUT (model LMC-2022FX)
Mixing console LMC-2642FX has a separate output for
the effects device, which is unbalanced and stereo (tip=
left signal; ring= right signal; sleeve= ground/shielding).
Thus, you can record, for example, a vocal track
enhanced with reverb in parallel to a "dry" vocal track;
when doing the mix-down later on, you can freely
determine the amount of reverb added.
FOOT SW
Connect a standard foot switch to the foot switch jack
and use this to switch the effects processor on and off. A
light at the bottom of the display indicates whether the
effects processor has been muted by the foot switch. In
Chapter 5 you will find an illustration showing how to
connect your foot switch correctly.
LEVEL
The LED level meter on the effects module should
display a sufficiently high level. Take care to ensure that
the clip LED only lights up at peak levels. If it is lit
constantly, you are overloading the effects processor
and this could cause unpleasant distortion.
PROGRAM
You can select the effect preset by turning the
PROGRAM control. The display flashes with the number
of the current preset. To recall the selected preset, press
on the button; the flashing stops. You can also recall the
selected preset with the foot switch.
