Stereo channels | Behringer UB1202FX, UB1002FX instruction

EURORACK UB1002FX/UB1202FX

In the UB1002FX/UB1202FX, the FX send is routed directly to the built-in effects processor. To make sure that the effects processor receives an input signal, you shouldn’t turn this control all the way to the left (-oo).

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.

LEVEL

The LEVEL control determines the level of the channel signal in the main mix.

+Attention: Since the FX path for the effect processor is connected post-fader, the LEVEL control has to be turned up in order to get this channel’s signal to the effects processor!

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 TRIM control to reduce the preamp level until the LED does not light anymore.

2.2 Stereo channels

LINE IN

Each stereo channel has two balanced line level inputs on 1/4" connectors for left and right channels. If only the connector 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 connectors.

The FX send of the stereo channels functions similar to that of the mono channels. However, since the FX send bus is mono, a mono sum is first taken from the stereo input before it is sent to the FX bus.

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 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).

FX SEND

The FX SEND connector outputs the signal you picked up from the individual channels using the FX controls. You can connect this to the input of an external effects device in order to process the FX bus’ master signal. Once an effects mix is created, the processed signal can then be routed from the effects device outputs back into a stereo input.

+If the connected effects processor receives no input signal, the FX SEND control is probably too low. This also goes for the built-in effects processor.

+Adjust your external effects processor to 100% wet (effects signal only), because the effects signal is added to the main mix along with the “dry” channel signals.

+In this instance, the FX control of the channel being used as an effects return should be turned fully counterclockwise, otherwise feedback problems can occur!

PHONES/CONTROL ROOM OUT

The stereo PHONES connector (at the top of the connector panel) is where headphones are connected. The unbalanced CONTROL ROOM OUT connectors carry the summed effects and main mix signals as well as soloed channel signals. The PHONES/CONTROL ROOM control in the main section adjusts the level of both headphones and main monitor outputs.

MAIN OUT

The MAIN OUT connectors are unbalanced mono connectors. The main mix signal appears here at a level of 0 dBu. The MAIN MIX fader adjusts the volume of these outputs. Depending on how you wish to use your mixer and which gear you own, you can connect the following equipment:

Live PA systems:

A stereo dynamics processor (optional), stereo equalizer (optional) and the stereo power amplifier for full-range loudspeakers with passive crossovers.
