Introduction
Thank you for choosing the Quad EQ processor from
Mackie. It is part of a family of digital outboard gear
based on our TT24 digital mixer engineering develop-
ments. We thought it would be good to share the love,
not to mention the design and engineering expertise
developed during the TT24 program.
The four-channel, 30-band graphic, Adaptive-Q
equalizer has a user-friendly front panel, and a host of
features that go beyond it’s simple appearance.
The Quad EQ comes with its own measurement micro-
phone, and has a built-in Sound Pressure Level (SPL)
meter, and Real Time Analyzer (RTA) functions. These
allow for simple viewing of lter settings vs. actual
measurement.
The simplicity of the interface makes the unit easy to
use for beginners, and fast enough for professional live
sound engineers. The sound quality makes the Quad EQ
lovely for the high-end user as well.
The clever Adaptive-Q design allows the equaliza-
tion to follow the settings of the 30 EQ lters, without
the ripple and boosting effects of common EQ units. In
other words, what you see in the display is what you get.
People are really attracted to sound engineers who
know how to operate equipment with lots of ashing
lights, so the Quad EQ was especially designed with
plenty of lights in operation.

HOW TO USE THIS MANUAL
We know that many of you can’t wait to get your new
Quad EQ hooked up, and you’re probably going to use
this manual to line your cat’s litter box. Anyway...the
rst section after this Introduction is a Getting Started
guide to help you get things set up fast so you can start
using it right away. Right after that are the ever popular
hook-up diagrams that show you some typical setups.
When you have time, read the Features Description
section. This describes in detail every meter, button,
and connection point on the Quad EQ. Throughout
this section you’ll nd illustrations with each feature
numbered. If you want to know more about a feature,
simply locate it on the appropriate illustration, notice
the number attached to it, and nd that number in the
nearby paragraphs. These complimentary numbers can
also be used as lottery or telephone numbers!
