Introduction

Thank you for choosing the Quad-Comp/Gate proces-

sor from Mackie. It is part of a family of digital outboard 
gear based on our TT24 digital mixer engineering devel-
opments. 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 gate/expander and compressor/

limiter has a friendly front panel and a host of features 
that go beyond its simple appearance. Built-in indepen-
dent key filters for both the gate and compressor allow 
for frequency-dependent gating and compression. 

The simplicity of the interface makes the unit practi-

cal for entry level users, and fast enough for profession-
al live sound engineers in any environment and studio 
application. The sound quality of the processing  makes 
the unit lovely for the high end user as well.

The Quad-Comp/Gate is stuffed full of compression 

and gating, just waiting to be unleashed! 

FEATURES

•  4 channels of digital compression/limiting and 

gate/expansion

•  Algorithms developed, tuned, pruned and  

watered by Acuma Labs digital engineering 
group

•  Unique, easy to use front panel designed for 

intuitive live use

•  Individual gain reduction meters and output 

meters for each channel

•  Individual key filtering per gate and compressor
•  99 snapshots for instant store and recall of set-

tings

•  Stereo Linking of channels A and B, C and D
•  XLR and TRS I/O connections

•  TRS Sidechain send and return connections
•  Convenient 2RU rackmounted, rugged and 

reliable design

•  “Planet Earth” power-supply operates on volt-

ages between 100 and 240 VAC

•  Standard IEC power receptacle and power cord
•  Printed manual from finest genuine grown-in-

the-ground, gently cut down, tree-wood

HOW TO USE THIS MANUAL

We know that many of you can’t wait to get your new 

Quad Comp/Gate hooked up, and you’re probably not 
going to read this manual at all. Or you might not admit 
to it anyway.

If your conscience does get the better of you, read the 

safety instructions and the Getting Started guide. These 
will help you get things set up fast, so you can start us-
ing it right away. After that are the ever popular hook-up 
diagrams that show some typical setups.

Then, when you have time, read the Features De-

scription section. This describes in detail every meter, 
button, and connection point on the Quad-Comp/Gate. 
Throughout this section you’ll find illustrations with 
each feature numbered. If you want to know more about 
a feature, simply locate it on the appropriate illustra-
tion, notice the number attached to it, and find that 
number in the nearby paragraphs.

This icon marks information that is criti-

cally important or unique to the Quad Comp/
Gate. For your own good, read them and 
remember them. They will be on the final test.

This icon leads you to in-depth explana-

tions of features and practical tips. While not 
mandatory, they usually have some valuable 
nuggets of information.

Appendix A is a section on troubleshooting and repair 

information.

Appendix B is a section on connectors: XLR connec-

tors, TRS balanced connectors, TS unbalanced connec-
tors, and Insert connectors.

Appendix C shows the technical specifications, and a 

block diagram showing the internal signal path and gen-
eral goings-on within the Quad Comp/Gate. On a scale of 
one to ten, you will find the block diagram very useful.

Please write your serial number here for future 

reference (i.e., insurance claims, tech support, 

return authorization, etc.)
