Main mix fader

MAIN MIX
Use the high-precision quality faders to control the output
level of the main mix.
Main out connectors
Fig. 2.12:
MAIN OUT
The
MAIN
outputs carry the MAIN MIX signal and are on
balanced XLR connectors with a nominal level of +4 dBu.
Depending on how you wish to use your mixer and which
gear you own, you can connect the following equipment:
Live PA systems:
A stereo dynamics processor (optional), stereo equalizer
(optional) and the stereo power amplifier for full-range
loud-speakers with passive crossovers.
If you wish to use multi-way loudspeaker systems without
an integrated crossover, you have to use an active crossover
and several power amplifiers. Often, limiters are already
built into active crossovers (e.g. BEHRINGER SUPER-X PRO
CX2310 and ULTRADRIVE PRO DCX2496). Active crossovers
are implemented directly before the power amplifier, and
they divide the frequency range into several segments that
are first amplified in the amplifiers and then passed onto the
corresponding loudspeakers.
Recording:
For mastering, using a stereo compressor such as the
COMPOSER PRO-XL MDX2600 can be recommended.
Use it to custom-tailor the dynamic characteristics of your
signal to the dynamic range of the recording equipment
you are using. The signal is in this case passed on from the
compressor into the recorder.
PHONES
The
PHONES
control adjusts the volume of the headphones
connected to the PHONS/CTRL connector. If you connect
active monitors or an amplifier, use this connector to adjust
the output signal level.
CAUTION!
!
We would like to draw your attention to the fact that
◊
extreme volumes may damage your hearing and/or
your headphones or loudspeakers. Turn the MAIN MIX
faders and the PHONES control in the main section
fully down before you switch on the unit. Always be
careful to set the appropriate volume.
PHONS/CTRL connector
Fig. 2.13:
PHONS/CTRL connector
You can connect headphones to this ¼
"
TRS connector.
The connector can also be used for feeding active monitor
loudspeakers (or an amplifier) in your control room. For this
purpose, the signal is taken directly before it is passed on to
the main mix faders.

The red “

” LED lights up when the phantom power
supply is switched on. The phantom power supply is
necessary for condenser microphones and is activated using
the corresponding switch on the rear of the device.
Connect microphones
◊
before you switch on the
phantom power supply. Please do not connect
microphones to the mixer (or the stagebox/wallbox)
while the phantom power supply is switched on. 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 system stabilization.
LEVEL METER/CLIP
The high-precision level meter accurately displays the
appropriate signal level.
LEVEL SETTING:
When recording to a digital device, the recorder’s peak
meter should not exceed 0 dB. This is because, unlike analog
recordings, slightly excessive levels can create unpleasant
digital distortion.
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 signal level at
frequencies above 1 kHz. This is why, for example, a Hi-Hat
should only be driven as far as -10 dB. Snare drums should
be driven to approx. 0 dB.
The peak meters of your XENYX display the level
◊
virtually independent of frequency. A recording level
of 0 dB is recommended for all signal types.
Graphic 7-band equalizer
2.4
The graphic stereo equalizer
Fig. 2.15:
The graphic stereo equalizer allows you to tailor the sound
to the room acoustics.
FBQ FEEDBACK DETECTION
The switch turns on the FBQ Feedback Detection System. It
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.
Logically, at least one (ideally several) microphone
◊
channels have to be open for feedback to occur at all!
Feedback is particularly common when stage monitors
(“wedges”) are concerned, because monitors project sound
in the direction of microphones. Therefore, you can also use
the FBQ Feedback Detection for monitors by placing the
equalizer in the monitor bus (see MAIN MIX/MONITOR).
EQ IN
Use this switch to activate the graphic equalizer. When
activated, the fader LEDs will illuminate.
MAIN MIX/MONITOR
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.

Voltage supply and fuse
Fig. 2.16:
FUSE HOLDER/IEC MAINS RECEPTACLE
The console is connected to the mains via the cable
supplied, which meets the required safety standards. Blown
fuses must only be replaced by fuses of the same type and
rating. The mains connection is made via a cable with IEC
mains connector. An appropriate mains cable is supplied
with the equipment.
POWER
Use the
POWER
switch to power up the mixing console. The
POWER switch should always be in the “Off” position when
you are about to connect your unit to the mains.
To disconnect the unit from the mains, pull out the main
cord plug. When installing the product, ensure that the plug
is easily accessible. If mounting in a rack, ensure that the
mains can be easily disconnected by a plug pull or by an
all-pole disconnect switch on or near the rack.
Attention: The POWER switch does not fully disconnect
◊
the unit from the mains. Unplug the power cord
completely when the unit is not used for prolonged
periods of time.
