MS1202-VLZ PATCHBAY DESCRIPTION At the risk of stating the obvious, this is where you plug everything in: microphones, line-level instruments and effects, head- phones, and the ultimate destination for your sound: a tape recorder, PA system, etc. MIC INPUTS (Channels 1–4) We use phantom-powered, balanced microphone inputs just like the big studio mega-consoles, for exactly the same reason:...

MUTE/ALT 3-4 The dual-purpose MUTE/ALT 3-4 bus is a Mackie signature. When Greg was designing our first product, he had to include a MUTE switch for each channel. MUTE switches do just what they sound like they do. They turn off the signal by “routing”...

else useful… like a separate stereo bus?” So MUTE/ALT 3-4 really serves two functions — muting (often used during a mixdown or live show), and signal routing (for multitrack and live work) where it acts as an extra stereo bus. To use this as a MUTE switch, all you have to do is not use the ALT 3-4 outputs.
Page 20: Aux Send
LOW EQ This control gives you up to 15dB boost or cut at 80Hz. The circuit is flat (no boost or cut) at the center detent position. This fre- quency represents the punch in bass drums, bass guitar, fat synth patches, and some really serious male singers.
Page 21: Output Section Description
That’ s why those “wall wart” mixers are of- ten noisy–they can’t power a VLZ circuit. At Mackie, audio quality is much more important than the price of wall warts. All of our mixers employ VLZ and built-in power supplies that deliver more...
Page 22: Control Room/Phones
Now you know how to select the signals you want to send to the engineer’s control room or phones. From there, these signals all pass through the same level control, aptly named: CONTROL ROOM/PHONES As you might expect, this knob controls the levels of both the stereo CONTROL ROOM and PHONES outputs outputs...

— to remind you that at least one channel is in SOLO, and to let you know that you’re mixing on a Mackie. No other company is so concerned about your level of SOLO aware- ness. If you work on a mixer that has a solo function with no indicator lights, and you happen to forget you’re in solo, you can easily be...

As with some other level controls, you may never need the additional gain, but if you ever do, you’ll be glad you bought a Mackie. This is usually the knob you turn up when the lead singer glares at you, points at his stage monitor, and sticks his thumb up in the air.

AUX RETURNS These two controls set the overall level of effects received from STEREO AUX RETURN in- puts 1 and 2 . These controls are designed to handle a wide range of signal levels, from off, to unity gain at the detent, with 20dB gain fully clockwise, to compensate for low-level effects.

Page 27 2. PRE-MUTE MOD This modification changes AUX SEND 1 (in post mode) and AUX SEND 2 to receive signal regardless of the channel’s MUTE/ALT 3-4 switch position, but still be post-fader (GAIN knob). In order to convert the entire mixer, it must be done on each channel.
Page 28 3. MAIN MIX SOURCE MOD This modification changes the SOURCE matrix’s MAIN MIX selection to tap the stereo signal before the MAIN MIX level control (pre) instead of after (post). This could be especially handy for live work where the engi- neer wants to be able to control the MAIN MIX level (sent to the house system) without changing the level in his headphones.

120VAC, 50/60Hz, 25 watts Weight Dimensions 11.8" x 11.2" x 2.6" (300mm x 284mm 66mm) Mackie Designs is always striving to improve our mixers by incorporating new and improved materi- als, components and manufacturing methods. Because we’re always trying to make things better, we reserve the right to change these specifications at any time, without notice.
Page 32: Service Info
Doing so might save you from the deprivation of your mixer and the associated suffering. Of all Mackie products returned for service (which is hardly any at all), roughly 50% are coded “CND” — Could Not Duplicate, which usually means the problem lay somewhere other than the mixer.
Page 33 The Audio Dictionary, by Glenn White; Tech Terms, by Peterson & Oppenheimer; Handbook for Sound Engineers, by Glen Ballou, Mackie Mixer Book by Rudy Trubitt and Sound Reinforcement Handbook, by Gary Davis. An acronym for After Fade Listen, which is another way of saying post-fader solo function.
Page 34 It does not go out on the air or to the main mixing buses. This “cueing” circuit is the same as pre-fader (PFL) solo on a Mackie mixer, and often the terms are interchangeable. See decibel.
Page 35 dynamic In sound work, dynamic refers to the class of microphones that generate electrical signals by the movement of a coil in a magnetic field. Dynamic microphones are rugged, relatively inexpensive, capable of very good performance and do not require external power. dynamic range The range between the maximum and mini- mum sound levels that a sound system can...
Page 36 filter A simple equalizer designed to remove cer- tain ranges of frequencies. A low-cut filter (also called a high-pass filter) reduces or eliminates frequencies below its cutoff fre- quency. There are also high-cut (low-pass) filters, bandpass filters, which cut both high and low frequencies but leave a band of fre- quencies in the middle untouched, and notch filters, which remove a narrow band but leave...

Page 39 Generally, phantom power is safe to use with non-condenser microphones as well, especially dynamic microphones. However, unbalanced microphones, some electronic equipment (such as some wireless microphone receivers) and some ribbon microphones can short out the phantom power and be severely damaged. Check the manufacturer’s recommendations and be careful! phasing...
Page 40 A term used to describe a secondary mix and output of the input signals, typically used for foldback monitors, headphone monitors, or effects devices. Mackie mixers call it an Aux Send. shelving A term used to describe the shape of an equalizer’s frequency response.
Page 41 Another common TRS application is for insert jacks, used for insert- ing an external processor into the signal path. In Mackie mixers, the tip is send, ring is re- turn, and sleeve is ground. Acronym for Tip-Sleeve, a scheme for con- necting two conductors through a single plug or jack.
Page 42: Appendix: Connections
APPENDIX B: CONNECTIONS “XLR” CONNECTORS Mackie mixers use 3-pin female “XLR” con- nectors on all microphone inputs, with pin 1 wired to the grounded (earthed) shield, pin 2 wired to the “high” (”hot” or positive polarity) side of the audio signal and pin 3 wired to the “low”...

Page 44 MACKIE STEREO INPUTS AND RETURNS: Mono, Stereo, Whatever Stereo line inputs and stereo AUX returns are a fine example of the Mackie philosophy (which we just made up) of Maximum Flex- ibility with Minimum Headache. The inputs and returns will automatically be mono or stereo, depending upon how you use the jacks.
Page 45: Appendix: Balanced Lines, Phantom Powering
APPENDIX C: Balanced Lines, Phantom Powering, Grounding and Other Arcane Mysteries Balanced Lines Balanced lines offer increased immunity to external noise (specifically, hum and buzz). Because a balanced system is able to minimize noise, it is the preferred interconnect method, especially in cases where very long lengths of cable are being used.

Page 47 Do’s and Don’ts of Fixed Installations If you install sound systems into fixed in- stallations, there are a number of things that you can do to make your life easier and that increase the likelihood of the sound system operating in a predictable manner. Even if you don’t do fixed installations, these are good practices for any sound system, installed.
