9 EURORACK UB1222FX-PRO User Manual ◊ When you use the MAIN MIX fader to reduce the overall volume, keep in mind that the subwoofer is still receiving a signal! FX TO MON You can use this control to insert an effects signal from the built-in effects processor to your monitor mix. Of course, to do this, your effects processor must first receive a signal, i.e. the FX controls in the channel strips must be turned up, and the FX SEND fader (see fig. 2.6) hast to be open. 2.3.3 Aux return connectors L 1 R (MONO) AUX RTN L R 2 Fig. 2.8: Aux return connectors MON MUTE If the MON MUTE switch is pressed, the monitor bus is muted, i.e. there is no signal at the MON SEND connector. FX SEND The FX SEND fader determines the overall level of the effects bus. Both external effects processors (via the FX SEND connector) and the built-in processor only receive an input signal if this control is open. FX TO MAIN Use the FX TO MAIN control to feed the effects signal into the main mix. If the control is turned all the way to the left, no effects signal can be heard. FX MUTE If the FX MUTE switch is pressed, the effects channel is muted, i.e. no signal is present at the FX SEND connector and the effects processor no longer receives an input signal. 2.3.2 Monitor send and FX send connector MON AUX RETURN 1 The AUX RETURN 1 connectors generally serve as the return path for the effects mix generated using the FX send. This is where you connect the output signal of the external effects device. If only the left connector is used, the aux return 1 automatically operates in mono. ◊ You can also use these connectors as additional line inputs. AUX RETURN 2 The AUX RETURN 2 connectors are used exactly the same way as the AUX RETURN 1 connectors. If these connectors already function as additional inputs, you can route the effects signal back into the console via a different stereo channel, with the added benefit that the channel EQ can be used to adjust the frequency response of the effects return signal. ◊ In this instance, the FX control of the channel being used as an effects return should be turned fully counter-clockwise, otherwise feedback problems can occur! 2.3.4 2-Track return channel, voice canceller and connection socket SEND Fig. 2.7: Aux send connectors MON and FX MON SEND Connect the input of your monitor power amp or an active monitor system here to make the monitor mix audible to the musicians on the stage. The signal mix is created using the channels' MON controls. 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 the AUX RETURN connectors. ◊ If the connected effects processor receives no input signal, the FX MUTE switch is probably pressed and/or the FX SEND control is 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. Fig. 2.9: 2-Track return channel This channel, intended especially for connecting stereo signal sources (CD players, DAT recorders or even sound cards) features a particularly practical feature: the VOICE CANCELLER. VOICE CANCELLER Here, you have a filter circuitry that lets you almost entirely remove the vocal portion of a recording. The filter is constructed in such a way that voice frequencies are targeted without majorly affecting the rest of the signal. Additionally, the filter seizes only the middle of the stereo image, exactly there where the vocals are typically located.
