2. Connect speakers to your amplifier’s outputs (unless, of course, you have powered speakers, such as the Mackie SRM 450 active monitors). 3. Plug all the sound system components into suitable AC outlets; properly grounded and capable of delivering adequate current.
WITH THE SAME TYPE FUSE AND RATING 1. MIC The mono channels are equipped with Mackie’s cutting-edge XDR preamplifiers; providing up to 60dB of rugged, low-noise, crystal-clear, phantom-powered am- plification. Their balanced circuitry rejects all manner of extraneous interference. Profes- sional condenser, dynamic and ribbon mics will all sound excellent through these XLR inputs.
3. INSERT With nothing plugged into this jack, the channel’s signal goes straight through the mic/ line preamp to the channel strip. With an ex- ternal effects device plugged into this jack, the channel’s signal leaves the mixer, goes through the effects device and back into the channel strip.

CHANNEL STRIP FEATURES The channel strip is where you dress up each channel’s audio: setting the gain, adding EQ, riding the fader, tapping signal off to stage monitors and effects devices. After a signal leaves the channel strip it goes through a mix stage and on to the master section (page 22).
Mono Stereo channels channels EQ: (28 through 34) TRIM TRIM The mixer has low shelving, mid peaking and high shelving EQ. “Shelv- +15dB 45dB ing” means that the circuitry boosts or cuts all frequencies past the specified frequency. For example, boosting the LOW EQ knob boosts bass frequencies at 80Hz and below.
35. THIS OL’ LED This LED represents a bad thing: If a channel’s OL LED lights up, its signal is too hot, and subsequent circuitry may overload (clip). To correct this, perform the SET THE LEVELS procedure on page 8. 36.

+4dBu output signal, will actually dis- play 0dB on its meters. A “-10” mixer, with a -10dBV output signal, will also display 0dB. To eliminate that confusion, Mackie’s com- pact mixers use a simpler method, where zero equals zero: 0dBu (0.775V) at the output shows as 0dB VU on the meters.

60. SUBGROUP FADERS These faders provide 10dB of gain fully up, unity gain at the “U” label and are effectively muted fully down. Each fader is the master level control for a subgroup’s signal, affecting both the SUB OUTS (8) and the main mix, via L/R ASSIGN (59).
