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
2.1.1 Microphone and line inputs
Fig. 2.1: Connectors and controls of mic/line inputs
MIC
Each mono input channel offers a balanced microphone input via the XLR
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 2.3.5
“Phantom power and LED displays”.

LINE IN
Each mono input also features a balanced line input on a 1/4" connector.
Each mono input also features a balanced line input on a 1/4" connector.
Unbalanced devices (mono jacks) 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!

GAIN

Use the GAIN 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.
2.1.2 Equalizer
All mono input channels include a 3-band equalizer, except for the UB502,
All mono input channels include a 3-band equalizer, except for the UB502,
which is equipped with a 2-band EQ. All bands provide boost or cut of up to 15 dB.
In the central position, the equalizer is inactive.

EQ
The upper (HI) and the lower band (LO) are shelving filters that increase or
The upper (HI) and the lower band (LO) 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 (UB802/UB1002/ UB1202) is configured as a peak filter with a
center frequency of 2.5 kHz.
LOW CUT
In addition, the mono channels (UB1002 and UB1202) are equipped with a steep
In addition, the mono channels (UB1002 and UB1202) are equipped with a steep
LO CUT filter (slope at 18 dB/oct., -3 dB at 75 Hz) designed to eliminate unwanted
low-frequency signal components.
2.1.3 FX sends, panorama and level adjustment
Fig. 2.3: The FX send/panorama/level controls
FX (UB802/UB1002/UB1202 only)
FX sends (or AUX sends) enable you to feed signals via a variable control from
FX sends (or AUX 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
console’s 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 aux
return connectors (UB802) or normal channel inputs. 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
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 channel’s 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.
PAN
The PAN control determines the position of the channel signal within the stereo
The PAN control determines the position of the channel signal within the stereo
image. This control features a constant-power characteristic, which means the
signal is always maintained at a constant level, irrespective of position in the
stereo panorama.
LEVEL
The LEVEL control determines the level of the channel signal in the main mix.
The LEVEL control determines the level of the channel signal in the main mix.
CLIP
The CLIP LED’s of the mono channels illuminate when the input signal is driven
The CLIP LED’s of the mono channels illuminate when the input signal is driven
too high, which could cause distortion. If this happens, use the GAIN control to
reduce the preamp level until the LED does not light anymore.
