1.3 Before you get started
1.3.1 Shipment
Your mixing console was carefully packed in the factory to
guarantee safe transport. Nevertheless, we recommend that
you carefully examine the packaging and its contents for any
signs of physical damage, which may have occurred during
transit.
+ If the unit is damaged, please do NOT return it to us,
but notify your dealer and the shipping company
immediately, otherwise claims for damage or
replacement may not be granted.
1.3.2 Initial operation
Be sure that there is enough space around the unit for cooling
purposes and to avoid over-heating please do not place your
mixing console on high-temperature devices such as radiators
or power amps. The console is connected to the mains via the
supplied cable. The console meets the required safety standards.
Blown fuses must only be replaced by fuses of the same type
and rating.
+ Never connect the EURORACK to the power supply
unit when the latter is connected to the mains!
First connect the power supply unit to the console,
then connect the power supply unit to the mains.
+ Please note that all units must be properly
grounded. For your own safety, you should never
remove any ground connectors from electrical
devices or power cables, or render them in-
operative.
+ Please ensure that only qualified people install and
operate the mixing console. During installation and
operation, the user must have sufficient electrical
contact to earth, otherwise electrostatic discharges
might affect the operation of the unit.
1.3.3 Warranty
Please take time to fill out and return the warranty card within
14 days after the date of purchase, so as to be entitled to benefit
from our extended warranty. Alternatively, you can use our
online registration option available on the world wide web
(www.behringer.com). You will find the serial number on the
rear of your mixing console.
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 connector and also features a switchable +48V
phantom power supply for condenser microphones. Please note:
the EURORACK UB502 does not supply phantom power.
+ 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. 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, 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.
Fig. 2.2: The equalizer of the mono input channels
EQ
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 80Hz respectively. The mid band
(UB802/UB1002/UB1202) is configured as a peak filter with a
center frequency of 2.5 kHz.
LO CUT
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.
