ONYX 4•Bus down to the lowest note you ever heard. "Peaking" means that the frequencies around the center frequency are less affected by the EQ the further away they are. 12. AUX Sends These tap a portion of each channel's signal (pre or post-fader) out to either an effects processor (post-fader) or for stage monitoring (pre-fader). The AUX Send levels are controlled by the channel's AUX 1-6 knobs, and by the AUX SEND MASTERS knobs [55]. These are more than just effects and monitor sends. They can be used to create stereo in-ear monitor mixes, generate separate mixes for recording, for another zone, or "mix-minuses" for broadcast. 13. PAN PAN adjusts the amount of channel signal sent to the left versus the right outputs. With the PAN knob hard left, the signal feeds the MAIN LEFT (and GROUP 1 and 3, depending on the setting of the GROUP ASSIGN switches). With the knob hard right, the signal feeds the MAIN RIGHT (and GROUP 2 and 4). Constant Loudness 15. Channel Fader The fader controls the channel's level...from off to unity gain at the "U" marking, on up to 10 dB of additional gain. "U" Like Unity Gain Mackie mixers have a "U" symbol on many of the level controls. This "U" stands for "unity gain," meaning no change in signal level. Once you have adjusted the input signal to line-level, you can set the controls at "U" and your signals will travel through the mixer at optimal levels. What's more, many of the labels on our level controls are measured in decibels (dB), so you'll know what you're doing level-wise if you choose to change a control's settings. 16. Signal Level LEDs The Onyx 4•Bus PAN control employs a design called "Constant Loudness." If you have a channel panned hard left (or right) and then pan to the center, the signal is attenuated 3 dB to maintain the same apparent loudness. Otherwise, it would make the sound appear much louder when panned center. 14. MUTE Press this switch to mute the individual channel. This disconnects the channel's signal from all the Groups, the Main Mix, and Aux Send buses (pre* and postfader). You can still solo the channel (PFL) when the MUTE switch is pushed in. 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. * If the pre-fader Aux Send's internal jumper is wired for pre-Mute [56], the MUTE switch will not affect the PRE Aux Send. %1 )./54 -54% &!$%2 0!. !33)'. ).054 '!). ,/7#54 ).3%24 %1 $)2%#4 /54 02% %1 0/34 %1 ).4%2.!, *5-0%2 0/34 %1 02% %1 02% -54% ).4%2.!,*5-0%2 0/34 -54% 0/34 3)'.!, !583%.$ +./" 4/!583%.$ "530/34 &!$%2 !UX0REVS0OST 3IGNAL&LOW$IAGRAM 02%3)'.!, 4/!583%.$ "5302% &!$%2 4/!583%.$3  12 ONYX 4•Bus O O O O O O O O O O O O O O 80Hz -15 +15 EQ OUT IN AUX 1 MAX 2 MAX 3 MAX 4 MAX 5 MAX 6 MAX PAN L R MUTE 1 dB 10 5 OL U + 10 0 5 -20 10 ASSIGN 20 1 - 2 30 3 - 4 40 50 MAIN MIX 60 PFL
