Introduction
Thank you for choosing a Mackie HMX-56 Matrix
Headphone Mixer/Amplifier. This six-channel
headphone mixer features left and right TRS main
inputs, four TRS “source” inputs, as well as an effects
send and stereo effects return.
The HMX-56 provides six separate headphone mixes,
each of which can be comprised of the main stereo mix
and a combination of the four source inputs, which
could be aux sends or sub groups from your mixer, or
even individual channel direct outputs.
The effects send can be comprised of a combination
of the main stereo mix, the four source inputs, and the
stereo effects return, individually mixed to taste in each
of the headphone mixes. In addition, each channel has
its own headphone output level control.
The HMX-56 also makes a great stage monitor
mixer, allowing each musician to tweak his or her
individual monitor mix exactly how they want it. Just
use the phones outputs as inputs to your stage monitor
amplifiers or in-ear monitor system.
The rugged construction of the HMX-56 makes it a
roadworthy companion to your arsenal of gear either
inside or outside of a rack.
HOW TO USE THIS MANUAL
We know that many of you can’t wait to get your
new headphone amp hooked up, and you’re probably
not going to read the manual first (sigh!). So the first
section after this introduction is a Quick-Start Guide
called “Getting Started” to help you get the HMX-56 set
up fast so you can start using it right away. Right after
that are the ever popular hook-up diagrams that show
typical setups for live sound and recording.
Then, when you have time, read the Features
Description section. This describes every knob, switch,
and connection point on the HMX-56.
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
illustration, notice the number attached to it, and find
that number in the nearby paragraphs.
This icon marks information that is
critically important or unique to the
HMX-56. For your own good, read
them and remember them. They will
be on the final test.
This icon leads you to in-depth
explanations of features and practical
tips. While not mandatory, they
usually have some valuable nugget of
information.
A PLUG FOR THE CONNECTOR SECTION
Appendix B is a section on connectors: balanced
connectors, unbalanced connectors, and the phones
connectors used on the HMX-56.

THE GLOSSARY: A Haven of Non-Techiness for
the Neophyte
The “Glossary of Terms” is a fairly comprehensive
dictionary of pro-audio terms. If terms like “clipping,”
“noise floor,” or “unbalanced” leave you blank, refer to
this glossary for a quick explanation.
ARCANE MYSTERIES ILLUMINATED
“Arcane Mysteries” discusses some of the down ‘n’ dirty
practical realities of microphones, fixed installations,
grounding, and balanced versus unbalanced lines. It’s a
goldmine for the neophyte, and even the seasoned pro
might learn a thing or two.
