[. . . ] (Even though sends 2 and 4 are mono, all the AUX returns are ready for stereo signals generated within your effects boxes. ) Each input is a line level, unbalanced 1/4" TS standard phone jack, which routes the signal directly to the AUX Return amplifiers and front panel controls, and on to the main L/R mix bus. Just like the channel inputs, using the (Mono) Left input jack only will apply the return signal equally to both the left and right AUX inputs for a mono return.

EXPANDER IN ALT 3/4 OUTPUTS The Alt 3/4 Outputs are straightforward: Left and Right line level unbalanced 1/4" TS jacks, each connected to the Alt 3/4 buses. For instance, you could use them to send selected channels to your multitrack deck for bouncing or overdubbing (see the hook-up diagrams farther on for more possibilities). AUX SENDS Remember that on the front panel, AUX Sends 1 and 3 were stereo sends and AUX Sends 2 and 4 were mono?Well, it's true back here too, where they finally come out of the mixer. 14 CONTROL ROOM OUTPUTS This is where you plug in your monitor power amplifier. The Left and Right Control Room Outputs are line level unbalanced 1/4" TS jacks, controlled by the Control Room fader on the front panel.

Pin 2 is wired high, pin 3 is low and pin 1 is grounded, per AES standards. Phantom mic powering can be applied to both inputs with a flick of the Phantom Power switch . The mic sigMIC PREAMP GAIN nals won't go 1 2 anywhere unless you patch them. Each preamp has a line level unbalanced 1/4" TS MIC IN Mic Out jack. You can patch the mic out signal into any channel input or even into other pieces of line level equipment in your rack. GAIN R USE ONLY WITH LM-3204E EXPANDERS. EXPANDER IN PHONES OUT The Phones jack is located on the front panel to the right of the meters and below the Phones Level knob. The jack is a standard 1/4" TRS stereo headphone jack with the left channel on the tip, the right channel on the ring, and the common ground connection on the sleeve. It is an IC, and it will not drive a speaker and it will toast a power amp (if turned up). WARNING: Turn down the Phones level control before you plug in the headphones. Then inch the control up until you feel groovy.

Beginners: face the blackboard, please. Many of you reading this manual have a lot of experience in using mixers and mixing consoles. For you battle-scarred pros, Section 2 and the Block Diagram will probably be all that you need to look at. For those of you who are either new to using mixers or just like to read even larger quantities of our glib prose, we've provided this short section. It discusses the basic concepts and procedures used in recording, mixing and sound reinforcement work. If you can make some sense of it, you can check out your application and patching in Section 4 and start plugging things in. Somewhere between the noise and the clipping is an optimum level for your signal: high enough above the noise floor to render the hiss inaudible, and far enough below the distortion point to allow range for loud peaks of music to pass without clipping. [. . . ] Make sure that you encase the mixer in its plastic wrapper and insert all the foam blocks to properly protect the mixer. If we cannot duplicate the problem at the Mackie factory or establish the starting date of your Limited Warranty, we may, at our option, charge for service time. boxes or route numbers, please!) and DAYTIME phone number. TROUBLESHOOTING It benefits everyone if you do a bit of basic troubleshooting in advance of panicking and sending the unit back. Some low-key detective work will determine whether or not your mixer is really malfunctioning. [. . . ]
