EURORACK UB1222FX-PRO 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. + 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! 2.3.2 Monitor send and FX send connector 2.3.4 CD/tape return channel, voice canceller and connection socket 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. 2.3.3 Aux return connectors Fig. 2.8: Aux return connectors 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. Fig. 2.9: CD/tape 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. Possible applications for the Voice Canceller are obvious: you can very simply stage background music for Karaoke events. Of course, you can also do this at home or at your rehearsal room before you hit the stage. Singers with their own band can practice singing difficult parts using a complete playback from a tape player or a CD, thus minimizing rehearsal time. STANDBY If the STANDBY switch is pressed, all input channels with a mic connector (XLR connector) are muted. During breaks or stage conversion, you can prevent noise from entering the sound system via the microphones. Such noise can in the worst-case scenario even irreparably damage loudspeaker membranes. The cool thing about this is that the main mix faders can remain open, so that you can play music from a CD at the same time. Similarly, the faders for the muted channels can also remain in their position. To bring in other sound sources, you can use the CD/tape inputs, stereo input channels 9 to 12 and the aux return inputs. CD/TAPE MUTE Using this switch, the input signal from the CD/tape inputs is muted. CD/TAPE RET(URN) This stereo fader assigns the input signal from the CD/tape inputs into the main mix. 2.
