EURORACK UB1202/UB1002/UB802/UB502 Controls
(EN) Step 2: Controls
This chapter describes the various control
elements of your mixing console. All controls,
switches and connectors will be discussed
indetail.
(1) MIC – Each mono input channel oers a
balanced microphone input via the XLR
connector and also features switchable +48V
phantom power supply (UB802/1002/1202)
for condenser microphones. TheEURORACK
preamps provide undistorted and noise-free
gain as is typically knownonly from costly
outboardpreamps.
(2) LINE IN – Each mono input also features
a balanced line input on a ¼" 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!
(3) 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.
(4) 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.
(5) LOW CUT – In addition, the mono channels
(UB1002and UB1202) are equipped with a
steep LOWCUT lter designed to eliminate
unwanted low-frequency signalcomponents.
(6) FX (UB802/UB1002/UB1202 only) –
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 eects device. The return from
the eects 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.
(7) PAN – 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.
(8) LEVEL – The LEVEL control determines the
level of the channel signal in the main mix.
(9) CLIP – 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.
(10) LINE IN – Each stereo channel has two
balanced line level inputs on ¼" jacks for left
and right channels. If only the jack marked “L”
(left) is used, the channel operates in mono.
The stereo channels are designed to handle
typical line level signals. Bothinputs will also
accept unbalanced jacks.
(11) FX – The FX sends of the stereo channels
function similar to those of the mono
channels. However, since the FX send buses
are both mono, amono sum is rst taken from
the stereo input before it is sent to the FX bus.
The UB502 is not equipped with FXsends.
(12) BAL – The BAL(ANCE) control determines the
levels of left and right input signals relative
to each other before both signals are then
routed to the main stereo mix bus. If a channel
is operated in mono via the left line input,
this control has the same function as the PAN
control used in the mono channels.
(13) +4/-10 – The stereo inputs of the EURORACK
UB1002 and UB1202 have an input sensitivity
switch which selects between +4 dBu and
-10dBV. At-10dBV (home-recording level),
the input is more sensitive (requires less level
to drive it) than at +4dBu (studiolevel).
(14) STEREO AUX RETURN – UB802 only: the
STEREO AUX RETURN connectors are used
to bring the output of the external eects
device (whose input is derived from the
aux sends) back into the console. You can
instead use these connectors as additional
inputs, but any eects device will then have
to be brought back into the console via a
normal stereo channel. This does, however,
give you the ability to use the channel EQ on
the eects return signal if you wish. If only
the left connector is used, the AUX RETURN
automatically operates in mono. Use the
AUXRETURN control to determine how much
of the eects signal is sent to the main mix.
(15) FX SEND – The FX SEND output (does not
apply for UB502) should be connected
to the input of an external eects unit.
Thepost-fader FX signal you created using the
input channel FX controls is sent to the eects
unit via the FX SEND ouput. Use the FXSEND
control of the main section to adjust the
overall send level (UB1002 and UB1202 only).
(16) PHONES/CONTROL ROOM – The stereo
PHONES jack (at the top of the connector
panel) iswhere you connect headphones.
The unbalanced CTRL ROOM OUT jacks
carry the summed eects and main mix
signals, as well as soloed channel signals.
ThePHONES/CONTROL ROOM control adjusts
the level of both headphones and main
monitor outputs. TheUB502 is not equipped
with control roomoutputs.
(17) MAIN MIX – The MAIN OUT connectors are
unbalanced mono jacks. The main mix signal
appears here at a level of 0 dBu. TheMAIN
MIX fader adjusts the volume of these
outputs. TheEURORACK UB802 and UB502
mixing consoles feature a rotary control for
thispurpose.
(18) 2-TRACK INPUT – The 2-TRACK INPUTs
areused to bring an external signal source
(e.g. CD player, tapedeck, etc.) into the
console. They can also be used as a standard
stereo line input, so the output of a second
EURORACK or BEHRINGER ULTRALINK
PROMX882 can be connected.
(19) 2-TRACK OUTPUT – These connectors are
wired in parallel with the MAIN OUT and carry
the main mix signal (unbalanced). Connectthe
2-TRACK OUTPUT to the inputs of your
recording device. Theoutput level is adjusted
via the high-precision MAIN MIX fader or
rotary control (UB502/UB802).
(20) 2-TRACK TO MIX – When the TAPE TO
MIX switch is depressed, the 2-track input
is assigned to the main mix providing
an additional input for tape machines,
MIDIinstruments or other signal sources
thatdo not require any processing.
(21) 2-TRACK TO CTRL ROOM – Press the 2-TRACK
TOCTRL ROOM/PHONES switch if you want to
monitor the 2-track input via the CTRL ROOM
OUT. This provides an easy way to monitor
signals coming back from tape to ensure that
they are recordingcorrectly.
(22) FX TO CTRL ROOM – If you want to monitor
only the FX send signal in your headphones
or monitor speaker(s), press the FX TO CTRL
switch. This mutes the main mix signal while
routing the FXSEND output to the monitor(s).
The EURORACK UB802 andUB502 do not
feature this switch.
(23) +48 V – The +48 V LED lights up when
phantom power is on. The PHANTOM switch
activates the phantom power supply on the
XLR connectors of all mono channels.
(24) POWER – The POWER LED indicates that the
console is powered on.
(25) LEVEL INDICATOR – The high-precision
4-segment display accurately displays the
relevant signal level.
