[. . . ] "U" LIKE UNITY GAIN Mackie mixers have a "U" symbol on almost every level control. 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 every control at "U" and your signals will travel through the mixer at optimal levels. What's more, all 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. MUTE U EQ HI 12k -15 +15 U MID -15 +15 600 1. 5k FREQ 8k U LOW 80Hz 150 100 When you engage a channel's mute switch, its signal disappears from these outputs: MAIN , MAIN INSERT , SUB OUT 1-4 , OUT AUX SEND 1 & 2 , EFX SEND 1 & 2 (including the send to the EMAC EFFECTS ). The only thing it doesn't PROCESSOR switch, so mute is the channel's SOLO PFL you can audition channels, via headphones, without sending them to the main mix. SOLO PFL Engaging a channel's SOLO switch causes this dramatic turn of events: The PHONES and Meters , which ordinarily receive the main mix signals, instead receive the SOLO PFL signal. PFL, being a mono signal, is sent to both sides of the PHONES outputs and to the LEFT meter. Additionally, the RUDE SOLO LED flashes obnoxiously to remind you that "you're in solo. " The SOLO PFL signal is tapped before the channel's MUTE and Fader controls. It , LOW CUT , does, however, follow TRIM settings, making it the perfect tool and EQ for quick inspections of individual or multiple , MUTE channels. The channel's PAN and Fader settings have no effect on the SOLO signal. signal before the fader If you have a channel's fader set well below "U" (unity gain), SOLO won't know that and will send a unity gain signal to the PHONES output. That may result in a startling level boost in your headphones. ASSIGN PAN -15 +15 L R 1 ASSIGN MUTE dB 10 5 1-2 3-4 U 5 10 20 30 40 50 60 O O SOLO PFL Used in conjunction with the PAN knob, ASSIGN determines the final destination of a channel's signal. Engaging ASSIGN 1-2, for instance, sends that channel's signal to the SUB 1 and 2 Faders and, via their SUB ASSIGN switches, the MAIN MIX Fader . Typically, ASSIGN 1-2 will be engaged on all channels destined for the main mix. By configuring SUB 1 and 2 to feed the main mix, the channel ASSIGN 1-2 switches become the equivalent of being "Main Mix" switches. Some channels can use ASSIGN 3-4 instead; creating a submix for a set of channels (all the drum channels, for instance). Then, by configuring SUB 3 and 4 to also feed the main mix, you can "ride" the SUB 3 and 4 Faders independently of the rest of the mix. SUB Faders , SUB ASSIGN , and MAIN MIX Fader will explain this further. FADER Although the most self-explanatory item on a mixer, we'll explain it anyway: The fader is the master level control for the channel's sig14 MASTER SECTION FEATURES We hope you've understood, if not memorized, the CHANNEL STRIP FEATURES you just read. If you're still confused, please look them over again before you tackle this section. Don't worry, it's easy to swallow as long as you take it a bite at a time. A "+4" mixer, with a +4 dBu signal pouring out the back, will actually display 0 dB on its meters. A "­10" mixer, with a ­10 dBV signal trickling out, will also display 0 dB. At the risk of creating another standard, Mackie's compact mixers address the need of both crowds by calling things as they are: 0 dBu (0. 775V) at the output shows as 0 dB VU on the meters.
