Behringer Europack UB1204-Pro Owner's Manual

EURORACK UB1204FX-PRO/UB1204-PRO User Manual

PRE
When the PRE switch is pressed, aux send 1 is sourced pre-fader.

AUX 2 (FX)
The aux send labeled FX is for sending to effects devices and is thus set up 

to be post-fader.
In the UB1204FX-PRO, the FX send is routed directly to the built-in 

effects processor.

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.

MUTE/ALT 3-4
You can use the MUTE/ALT 3-4 switch to divert the channel from the main mix 

bus to the Alt 3-4 bus. This mutes the channel from the main mix.

MUTE LED
The MUTE LED indicates that the relevant channel is diverted to the submix 

(Alt 3-4 bus).

CLIP LED
The CLIP LED lights up when the input signal is driven too high. In this case, 

turn down the GAIN control and, if necessary, check the setting of the channel EQ.

SOLO
The SOLO switch (UB1204FX-PRO only) is used to route the channel signal to the 

solo bus (Solo In Place) or to the PFL bus (Pre Fader Listen). This enables you to 

monitor a channel signal without affecting the main output signal. The signal 

you hear is sourced either before (PFL, mono) or after (solo, stereo) both the pan 

control and the channel fader (see chapter 2.3.6 “Level meters and monitoring”).
The channel fader determines the level of the channel signal in the main mix 

(or submix).

Fig. 2.5: Stereo channel inputs and LEVEL switch

Each stereo channel has two balanced line level inputs on 1/4" connectors for left 

and right channels. If only the connector marked “L” is used, the channel operates 

in mono. Stereo channels are designed to handle typical line level signals.
Both inputs can also be used with unbalanced jacks.

LEVEL
For level matching, the stereo inputs feature a LEVEL switch which selects 

between +4 dBu and -10 dBV. At -10 dBV (home-recording level), the input is 

more sensitive than at +4 dBu (studio level).

2.2.2  Equalizer stereo channels
The equalizer of the stereo channels is, of course, stereo. The filter characteristics 

and crossover frequencies are the same as those of the mono channels. A stereo 

equalizer is always preferable to two mono equalizers if frequency correction of a 

stereo signal is needed. There is often a discrepancy between the settings of the 

left and the right channels when using separate equalizers.

2.2.3  Aux sends stereo channels
In principle, the aux sends of the stereo channels function in just the same way as 

those of the mono channels. As aux send paths are always mono, the signal on a 

stereo channel is first summed to mono before it reaches the aux bus.

BAL
The function of the BAL(ANCE) control corresponds to the PAN control in the 

mono channels.
The balance control determines the relative proportion between the left and 

right input signals before both signals are routed to the main stereo mix bus.
The MUTE/ALT 3-4 switch, the MUTE-LED, the CLIP-LED, the SOLO switch and the 

channel fader function in the same way as the mono channels.
