EURORACK UB502/UB802/UB1002/UB1202
Control elements and connectors6
The equalizer of the stereo input channelsFig. 2.5:
A stereo EQ is highly preferable to two mono equalizers. when
working on a stereo signal, as two separate EQ’s will usually
produce an unwanted discrepancy between the left and right
channels.
FX sends, balance and level adjustment2.2.3
The FX send/balance/level controlsFig. 2.6:
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.
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.
LEVEL
The LEVEL control determines the volume of the channel being
sent to the main mix.
+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).
Connector panel and main section2.3
Send/return effects path2.3.1
FX send/return connectorsFig. 2.7:
FX send/return controlsFig. 2.8:
STEREO AUX RETURN
UB802 only: the STEREO AUX RETURN connectors are used
to bring the output of the external effects device (whose input is
derived from the aux sends) back into the console. You can instead
use these connectors as additional inputs, but any effects 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 effects return signal if you wish.
When using a stereo channel as effects return path, the +
FX control of the relevant channel should generally be
turned fully down to avoid undesirable feedback.
If only the left connector is used, the AUX RETURN automatically
operates in mono. Use the AUX RET(URN) control to determine
how much of the effects signal is sent to the main mix.
FX SEND
The FX SEND output (does not apply for UB502) should be con-
nected to the input of an external effects unit. The post-fader FX
signal you created using the input channel FX controls is sent to
the effects 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).
Monitor and main mix2.3.2

PHONES/CONTROL ROOM
The stereo PHONES jack (at the top of the connector panel) is
where you connect headphones. The unbalanced CONTROL
ROOM OUT jacks carry the summed effects and main mix sig-
nals, 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.
