Owner's Manual 28. AUX SEND 1 and 2 (Aux Inputs 1-4) AUX SEND 5 and 6 (Aux Inputs 5-8) ance control on your home stereo (panning left turns down the right channel, and panning right turns down the left channel). These tap a portion of each channel's signal out to either an effects processor or for stage monitoring. These go to the same Aux Send buses as the mono channel Aux Sends. The Aux Input Aux Sends are always pre-fader. Aux Inputs 1-4 send their signals to Aux 1 and Aux 2. Aux Inputs 5-8 send their signals to Aux 5 and 6. 32. MUTE Press this switch to mute the channel. This disconnects the channel's signal from all the Groups, the Main Mix, and Aux Send buses. You can still solo the channel in PFL mode when the MUTE switch is pushed in. FEEDBACK LOOP WARNING: It is common to use an Aux Send to route signals to an external processor, and then return the signal from the processor via the Aux Inputs. Since the Aux Inputs on the Onyx 80 Series have Aux Sends of their own, you could accidentally route the Aux Input to an Aux Send that is being returned via that same Aux Input. This will cause a feedback loop, characterized by a LOUD howl or screech through the sound system, followed by howls of discontent from the audience. Be careful with the Aux Sends on the Aux Inputs! 29. AUX 3-4 Switch (Aux Inputs 1-4) AUX 7-8 Switch (Aux Inputs 5-8) For Aux Inputs 1-4: Press this switch to send the Aux Input signal to the Aux 3 and 4 buses instead of the Aux 1 and 2 buses. The Aux 1 and 2 knobs for that channel strip suddenly become Aux 3 and 4 knobs! For Aux Inputs 5-8: 33. Stereo Aux Input Fader The fader controls the stereo channel's level, from off to unity gain at the "U" marking, on up to 10 dB of additional gain. 34. Signal Level LEDs These LEDs indicate the channel's signal level after the GAIN and EQ controls, but just prior to the channel's fader. So even if the fader is turned down, you can see if a signal is present. If you've followed the "Set the Levels" procedure, the -20 and 0 LEDs should light frequently, the +10 LED should light occasionally, and the OL (Overload) LED should not light at all. If the OL LED is blinking frequently, the signal is probably distorted from overdriving the input. Either turn down the GAIN control or turn down the signal at its source. 35. GROUP and MAIN MIX ASSIGN Switches Press this switch to send the Aux Input signal to the Aux 7 and 8 buses instead of the Aux 5 and 6 buses. The Aux 5 and 6 knobs for that channel strip suddenly become Aux 7 and 8 knobs! Alongside each channel fader are two buttons referred to as channel assignment switches. Used in conjunction with the channel's BALANCE knob, they are used to determine the destination of the channel's signal. 30. STEREO Switch When this switch is up, both Aux Sends are fed a mono sum of the stereo channel's signal (L+R). The Aux Inputs are assignable to GROUPS 7-8 and the MAIN MIX. With the BALANCE knob [31] at the center detent, the left and right stereo signal is equally balanced. To feed only one side or the other, turn the BALANCE knob accordingly. When this switch is pushed in, the two Aux sends become a stereo send, with Aux 1 sending the right 36. PFL Solo Switch signal and Aux 2 sending the left signal. The same thing applies when Aux 3-4 is selected for Aux Inputs 1-4, and Like the PFL switch on the mono channels, this for Aux 5 and 6 (and Aux 7-8) for Aux Inputs 5-8. switch allows you to hear signals through your head- This is useful for providing a stereo mix for IEM (inear monitor) systems. phones or monitor outputs without having to route them to the MAIN or GROUP mixes. Since this is Pre-Fader Listen, you can listen to the stereo Aux Input even when the Aux Input fader is turned down. Unlike the mono 31. BALANCE channel PFL, the Aux Input PFL is a stereo signal (post- balance control). BALANCE adjusts the amount of channel signal sent to the left versus the right outputs. On the stereo Aux Input channels, the BALANCE knob works like the bal- PFL solo mode always overides AFL solo mode. The Rude Solo LEDS below the SOLO meters indicate which solo mode is active.
