2.3.2 Monitor send and FX send connector
Fig. 2.7: Aux send connectors MON and FX
MON SEND
Connect the input of your monitor power amp or an active
monitor system here to make the monitor mix audible to the
musicians on the stage. The signal mix is created using the
channels MON controls.
FX SEND
The
FX SEND
connector outputs the signal you picked up
from the individual channels using the FX controls. You can
connect this to the input of an external effects device in order to
process the FX bus master signal. Once an effects mix is created,
the processed signal can then be routed from the effects device
outputs back into the AUX RETURN connectors.
+
If the connected effects processor receives no
input signal, the FX MUTE switch is probably pressed
and/or the FX SEND control is too low. This also goes
for the built-in effects processor.
+
Adjust your external effects processor to 100% wet
(effects signal only), because the effects signal is
added to the main mix along with the dry channel
signals.
2.3.3 Aux return connectors
Fig. 2.8: Aux return connectors
AUX RETURN 1
The
AUX RETURN 1
connectors generally serve as the return
path for the effects mix generated using the FX send. This is
where you connect the output signal of the external effects
device. If only the left connector is used, the aux return 1
automatically operates in mono.
+
You can also use these connectors as additional
line inputs.
AUX RETURN 2
The AUX RETURN 2 connectors are used exactly the same
way as the AUX RETURN 1 connectors. If these connectors
already function as additional inputs, you can route the effects
signal back into the console via a different stereo channel, with
the added benefit that the channel EQ can be used to adjust the
frequency response of the effects return signal.
+
In this instance, the FX control of the channel being
used as an effects return should be turned fully
counter-clockwise, otherwise feedback problems
can occur!
2.3.4 CD/tape return channel, voice canceller and
connection socket
Fig. 2.9: CD/tape return channel
This channel, intended especially for connecting stereo signal
sources (CD players, DAT recorders or even sound cards)
features a particularly practical feature:
the
VOICE CANCELLER
.
VOICE CANCELLER
Here, you have a filter circuitry that lets you almost entirely
remove the vocal portion of a recording. The filter is constructed
in such a way that voice frequencies are targeted without majorly
affecting the rest of the signal. Additionally, the filter seizes only
the middle of the stereo image, exactly there where the vocals
are typically located.
Possible applications for the Voice Canceller are obvious: you
can very simply stage background music for Karaoke events. Of
course, you can also do this at home or at your rehearsal room
before you hit the stage. Singers with their own band can practice
singing difficult parts using a complete playback from a tape
player or a CD, thus minimizing rehearsal time.
STANDBY
If the
STANDBY
switch is pressed, all input channels with a
mic connector (XLR connector) are muted. During breaks or
stage conversion, you can prevent noise from entering the sound
system via the microphones. Such noise can in the worst-case
scenario even irreparably damage loudspeaker membranes. The
cool thing about this is that the main mix faders can remain open,
so that you can play music from a CD at the same time. Similarly,
the faders for the muted channels can also remain in their position.
To bring in other sound sources, you can use the CD/tape
inputs, stereo input channels 9 to 12 and the aux return inputs.
CD/TAPE MUTE
Using this switch, the input signal from the CD/tape inputs is
muted.
CD/TAPE RET(URN)
This stereo fader assigns the input signal from the CD/tape
inputs into the main mix.
