1.3.3 Online registration
Please do remember to register your new BEHRINGER equipment
right after your purchase by visiting www.behringer.com
(alternatively www.behringer.de) and kindly read the terms and
conditions of our warranty carefully.
Should your BEHRINGER product malfunction, our goal is to
have it repaired as quickly as possible. To arrange for warranty
service, please contact the retailer from whom the equipment
was purchased. Should your BEHRINGER dealer not be located
in your vicinity, you may directly contact one of our subsidiaries.
Corresponding contact information is included in the original
equipment packaging (Global Contact Information/European
Contact Information). Should your country not be listed, please
contact the distributor nearest you. A list of distributors can be
found in the support area of our website (www.behringer.com).
Registering your purchase and equipment with us helps us
process your repair claims quicker and more efficiently.
Thank you for your cooperation!
2. CONTROL ELEMENTS AND
CONNECTORS
This chapter describes the various control elements of your
mixing console. All controls, switches and connectors will be
discussed in detail.
2.1 Mono channels
Fig. 2.1: Connectors and controls on the mono channels
MIC
Each mono input channel offers a balanced microphone input
via the XLR connector and also features a switchable +48 V
phantom power supply for condenser microphones.
+
Please mute your playback system before you
activate the phantom power supply to prevent
switch-on thumps being directed to your
loudspeakers. Please also note the instructions
in chapter 2.4 Main section.
LINE IN
Each mono input also features a balanced line input on a 1/4"
connector. Unbalanced devices (mono connectors) can also be
connected to these inputs.
+
Please remember that you can only use either the
microphone or the line input of a channel at any
one time. You can never use both simultaneously!
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.
The scale has 2 different value ranges: the first value range
(
+10
to
+60
dB)
refers to the MIC input and shows the
amplification
for the signals fed in there.
The second value range (
+10
to
-40
dBu)
refers to the line
input and shows its
sensitivity
. The settings for equipment
with standard line-level signals (-10 dBV or +4 dBu) look like this:
While the TRIM control is turned all the way down, connect your
equipment. Set the TRIM control to the external devices standard
output level. If that unit has an output signal level display, it
should show 0 dB during signal peaks. For +4 dBu, turn up TRIM
slightly, for -10 dBV a bit more. Tweaking is done using the CLIP
LED.
EQ
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.
The upper (HIGH) and the lower band (LOW) 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 center frequency of
2.5 kHz. Unlike shelving filters, the peak filter processes a
frequency range that extends upwards and downwards around
its middle frequency.
LOW CUT
In addition, the mono channels are equipped with a steep
LOW
CUT
filter (slope at 18 dB/oct., -3 dB at 75 Hz) designed to
eliminate unwanted low-frequency signal components.
These
can be noises created by hand-held microphones, subsonic
noise or plosive sounds created by highly sensitive microphones.
FX
FX sends enable you to feed signals via a variable control
from one or more channels and sum these signals to a bus. The
bus appears at the consoles FX send output and can be fed
from there to an external effects device. The return from the
effects unit is then brought back into the console on the stereo
channels. Each FX send is mono and features up to +15 dB gain.
As the name suggests, the
FX
sends of the EURORACK mixing
consoles are intended to drive effects devices (reverb, delay,
etc.) and are therefore configured post-fader. This means that
the mix between dry signal and effect remains at the level
determined by the channels aux send, irrespective of the channel
fader setting. If this were not the case, the effects signal of the
channel would remain audible even when the fader is lowered
to zero. With UB mixing consoles, the channel fader is called
LEVEL control.
