Stereo Channel Equalizer; Stereo Channel Aux/Fx Send Buses; Stereo Channel Fader And Other Control Elements; Stereo Channels 21 - 24 (Sx2442Fx) Or 29 - 32 (Sx3242Fx) - Behringer Eurodesk SX3242FX User Manual

(20) All stereo channel strips have a TRIM control for gain adjust-
ment. Its scale ranges from +20 to -20 dB and allows you to
adapt the input level to the line inputs.

Stereo channel equalizer

Fig. 2.6: Stereo channel equalizer
The stereo channels are equipped with a stereo equalizer. The
filter types and cutoff frequencies for HIGH and LOW filters are
the same as on the mono channels. Instead of one semi-paramtric
midrange band, the stereo channels have two separate midrange
bands ((21) HIGH MID and LOW MID) with fixed mid-frequencies
(3 kHz and 400 Hz). Stereo EQs are preferable for processing the
frequency response of stereo signals. With two mono equalizers
you might encounter problems with different settings between the
left and right channels.
2.2.3

Stereo channel aux/FX send buses

Basically, the aux and FX buses on the stereo channels are the
same as on the mono channels. Since aux buses are always mono,
the signal from a stereo channel is first mixed to mono before it
is routed to the aux bus.
2.2.4 Stereo channel fader and
other control elements
Fig. 2.7: Channel fader, balance control, mute switch, etc.
(22) The BAL(ANCE) control has the same function as the PAN
control on the mono channels. It determines the relative
volume of the left and right input signals before they are
routed to the stereo main mix bus (or to two subgroups).
All other control elements of the stereo channels work in the same
ways as their counterparts on the mono channels (faders, MUTE
switches, etc.).
Please note: When you route a stereo channel to the
+
subgroups using the SUB switches, please be sure to
set the BAL control to its mid position, so that the signal
is sent to two subgroups and remains stereo.
EURODESK SX3242FX/SX2442FX
Your EURODESK has two stereo channels with an aux send
section ((23) AUX 1 and AUX 2) and one LEVEL control (24). For
these channels, the aux buses are hard-wired to pre-fader and are
therefore particularly useful for monitoring. They have no routing
switches and are always sent to the main mix. Like the normal
stereo channels they have two line-level inputs on1/4" TRS con-
nectors for the left and right channels, and a SOLO switch.
Similar to the CD/TAPE inputs (see (49)) the auxiliary stereo
channels can be connected to CD players, tape decks, etc., for
example, to feed in playback material.
The EURODESK has 4 subgroups enabling you to create mono or
stereo mixes from multiple input signals. Subgroups are controlled
from one (mono) or two (stereo) subgroup faders. Additionally, it
is possible to connect the subgroup outputs as tape sends to a
multi-track recorder.
(25) The subgroup faders determine the volume of the subgroup

you can monitor the subgroup signal without affecting the

left stereo side (=LEFT pressed), to the right stereo side
(=RIGHT pressed) or to both (=LEFT and RIGHT pressed).
For example, when you have created a stereo submix using
subgroups 1 and 2, be sure to route group 1 to the left and
group 2 to the right side to maintain proper stereo position-
ing. If it is a mono submix with just one subgroup, route it to
the left and right sides of the main mix to make the signal
audible on both sides.
