8 MAKE THE CONNECTIONS: 1. Make sure your amplifiers ar e turned off befor e making any connections. 2. Connect speakers to your amplifier’ s outputs (unless, of course, you have power ed 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 delive[...]

14 P A TCHBA Y This is where everything gets plugged in: microphones, line-level instruments, effects devices, headphones and the ultimate destination(s): P A system, tape r ecorder , etc. 1. MIC The mono channels are equipped with Mackie’s cutting-edge XDR TM microphone preamplifiers; providing up to 60dB of rugged, low-noise, crystal-clear , ph[...]

15 3. INSER T With nothing plugged into this jack, the channel’s signal goes straight through the mic/ line preamp to the channel strip. W ith 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. Use these jacks to send the channel signal th[...]

16 5. T APE OUT Use these stereo jacks to captur e the entire performance to tape. The signal at these jacks is the main mix, post-MAIN INSERTS (13) and post-MAIN MIX F ADER (72). Signals at these jacks will depend on the levels set by the main mix fader . RCA unbalanced wiring: Tip = hot, sleeve = shield 6. T APE IN Patch the outputs of an intermi[...]

17 9. STEREO AUX RETURNS Patch the outputs of external parallel ef- fects devices (reverb, delay , etc.) to these inputs. When connecting a mono device (just one cord), always use the LEFT (MONO) input and plug nothing into the RIGHT input. A trick called “jack normalling” will cause the signal to appear on both sides. Accepts 1/4” TRS balanc[...]

18 18. PHONES The stereo signal from each of these identi- cal outputs is a high-current version of the signal from CONTROL ROOM OUT (11). Con- nect TRS headphones to either or both jacks. The ster eo signal at these jacks is the same as the MAIN OUTS (12) (16), except when SOLO (39) or T APE RETURN TO PHONES/C-R (69) is engaged. Its level is indep[...]

19 CHANNEL STRIP FEA TURES AUX SEND: (26 and 27) 26. AUX These knobs tap a portion of each channel signal and send it out, via the AUX SENDS (10) jacks, to an amp & speakers for stage monitors or to an ef- fects device for parallel effects processing. Each AUX knob’s level ranges from off, through unity (center detent position), on up to 15dB[...]

20 EQ: (28 through 34) The mixer has low shelving, mid peaking and high shelving EQ. “Shelv- 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 . “Peaking” means that only a selected “hill” of frequencies sur - roundi[...]

21 35. THIS OL ’ LED This LED repr esents a bad thing: If a channel’s OL LED lights up, its signal is too hot, and subsequent circuitry may overload (clip). T o correct this, perform the SET THE LEVELS procedure on page 8. 36. -20 LED This LED repr esents a good thing: This LED will flicker in time with a channel’s signal when its level peaks[...]

22 MASTER SECTION FEA TURES In the master section, signals leaving the channel strips are mixed, manipulated and sent to the outputs in the patchbay . Addition- ally , there ar e four more ster eo inputs here, used to add effects to the main mix or other destinations. 45. LAMP This female BNC connector provides 12 volts on its center pin. Connect a[...]

23 STEREO AUX RETURNS: (48 to 52) 48. STEREO AUX RETURNS Having entered through the STEREO AUX RETURNS (9) jacks, effects returns ar e con- trolled by these knobs, and typically continue on to the MAIN MIX F ADER (72). Effect r e- turns are the “wet” signals, to be combined with the channels’ original “dry” signals in the main mix. T urne[...]

24 SUBGROUPS: (56 through 60) 56. AIR AIR is a high frequency peaking EQ cen- ter ed at 16kHz. T urned fully up, these controls provide 10dB of boost and fully down effec- tively bypasses the circuit. Use AIR to provide a crystalline effect to subgroups, helping them stand out in the overall mix. 57. SOLO Engaging this switch isolates the associate[...]

25 60. SUBGROUP F ADERS 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). SOLO: (61 through 65) 61. RUDE SOLO LIGHT Engaging any SOLO switch (39),(47[...]

26 70. PHONES/C-R LEVEL After the MAIN MIX F ADER (72), the main mix is sent to the MAIN OUTS (12) (16) and MONO MAIN OUT (14). It is also sent through this control, and exits at CONTROL ROOM OUT (11) and PHONES (18). This knob allows engineer’s listening levels to be set as desir ed without disturbing the main mix outputs.
