Owner's Manual the engineer is listening either to the control room [10] 3-4. This is a must for effects sends, since you want the outputs or the phones [11] outputs. The only difference levels of your "wet" s ignals to follow the level of the is that while the listening levels are controlled by the "dry," keeping them at the same ratio. For example, you control room / submix [32] knob, the meters read the do not want a returned echo to stay at one level, when source mix before that control, giving you the real facts you turn a channel down; you want it to go down as well. at all times, even if you're not listening at all. Post mute/alt 3-4 means that when a channel is muted, its aux send to an external processor is also muted. Thanks to the 802-VLZ3's wide dynamic range, you can get a good mix with peaks flashing anywhere between -20 and +10 dB on the meters. Most amplifiers clip at 37. AUX MASTER SEND about +10 dB, and some recorders aren't so forgiving This knob provides overall level control of aux send, either. For best real-world results, try to keep your just before it's delivered to the aux send [15] output. peaks between "0" and "+6". This knob goes from off (turned fully down), to unity Remember, audio meters are just tools to help assure you that your levels are "in the ballpark." You don't have to stare at them (unless you want to). gain at the center, with 10 dB of extra gain (turned fully up). You may never need the additional gain, but here it is anyway. This is the knob to turn up when the lead singer A word about Aux Sends are outputs, and returns are inputs. The channel aux [28] knobs taps the signal off each glares at you, points at his stage monitor, and sticks his thumb up in the air. (If he stuck his thumb down, you'd turn the knob down, but that never happens.) channel. The sum of the aux signals is sent to the aux master [37] knob before going to the aux send [15] 38. STEREO RETURN output. This control sets the overall level of effects received This output can be fed to the inputs of a reverb or other device. From there, the outputs of this external device are fed back to the mixer's stereo return [8] jacks, through the stereo return [38] level control, and finally delivered to the main mix. from the stereo return [8] inputs. This could be the affected (wet) processed signal returning from an effects processor, or the stereo signals from another synth or source. This control is designed to handle a wide range of signal levels, from off, to unity gain at the center, with 20 dB gain fully clockwise, to compensate So, the original "dry" signals go from the channels for low-level effects or sources. to the main mix, and the affected "wet" signals go from the stereo return [8] to the main mix. Once mixed together, the dry and wet signals combine to create a glorious sound. So, armed with this knowledge, let's visit the auxiliary world: Normally, set this knob at the center, and set the effects device or source's output control to whatever they call unity gain (check their manual). If that turns out to be too loud or too quiet, adjust the effects device or source's outputs, not the mixer. That way, the mixer's 36. PRE or POST (AUX) Besides being used to work effects into your mix, aux sends serve another critical role - that of delivering cue mixes to stage monitors, so musicians can hear what they're doing. On the 802-VLZ3, aux send can play either role, depending on the position of this switch. knobs are easy to relocate at the center. Signals passing through this control proceed directly to main mix. The stereo returns do not have mute/alt 3-4 switches, so if you want these signals to get to the alt 3-4 mix, you'll have to patch the effects device's outputs into one of the stereo channels instead of the stereo return, and mute/alt those channels. With this switch out (disengaged), aux send will tap a channel pre-fader and pre-mute/alt 3-4, meaning that no 39. POWER LED matter how you manipulate those controls as they feed the main mix, the aux send will continue to belt out that channel's signal. This is the preferred method for setting up stage monitor feeds, as its level is not affected by changes to the channel's level controls.
