7 XENYX 1202/1002/802/502 User Manual 2.1.3 FX sends, panorama and level adjustment LINE IN Each stereo channel has two balanced line level inputs on ¼" jacks for left and right channels. If only the jack 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 jacks. Fig. 2.3: The FX send/panorama/level controls 2.2.2 Equalizer stereo channels (802) The XENYX 802 features a stereo 3-band EQ in each stereo channel. The filter characteristics and cut-off frequencies are the same as those in the mono channels. A stereo EQ is highly preferable to two mono equalizers. When working on a stereo signal, as two separate EQ's will usually produce an unwanted discrepancy between the left and right channels. FX (1202/1002/802 only) FX sends (or AUX sends) enable you to feed signals via a variable control from one or more channels and sum these signals to a bus. The bus appears at the console's FX send output and can be fed from there to an external effects device. The return from the effects unit is then brought back into the console on the aux return connectors (802) or normal channel inputs. Each FX send is mono and features up to +15 dB gain. As the name suggests, the FX sends of the XENYX mixing consoles are intended to drive effects devices (reverb, delay, etc) and are therefore configured post-fader. This means that the mix between dry signal and effect remains at the level determined by the channel's aux send, irrespective of the channel fader setting. If this were not the case, the effects signal of the channel would remain audible even when the fader is lowered to zero.

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. 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 GAIN control to reduce the preamp level until the LED does not light anymore. 2.2 Stereo channels 2.2.1 Stereo line inputs Fig. 2.6: The FX send/balance/level controls FX The FX sends of the stereo channels function similar to those of the mono channels. However, since the FX send buses are both mono, a mono sum is first taken from the stereo input before it is sent to the FX bus. The 502 is not equipped with FXsends. 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.
