FR SERIES AMPLIFIERS
FR SERIES AMPLIFIERS
Introduction
Congratulations on the purchase of your new Mackie
power amplifier. Please read these instructions to get
the maximum performance from your amplifier, and to
keep the owner’s manual writer from getting sad. He’s
been a bit down recently, after his sweetheart in ac-
counting started going out with that amplifier designer,
just because he can whisper sweet nothings in Klingon
®
.
The FR series amplifiers are designed for continu-
ous duty in speech, music, and sound reinforcement
applications in churches, schools, offices, arenas, hotel
meeting rooms, convention centers, recreation facilities
and other venues demanding high performance, flexible
features, and rugged dependability.
A rear panel low-cut switch allows you to remove low
frequencies, and a clip-eliminator allows extra protec-
tion for your speakers by preventing the amplifier from
being overloaded.
The amplifier can operate in stereo, dual-mono, or
bridged mono. The output connections are Speakons
®
and binding posts for left, right and bridged mono.
The inputs are capable of accepting balanced XLR,
1/4" TRS, or unbalanced 1/4" TS connections from
line-level sources. Two front panel level controls allow
adjustment of the input signals.
The front panel has a rocker power switch with a
power LED, and each channel has a signal-present LED
and an overload LED.
The amplifier output stage is fully protected against
permanent damage caused by overloading, shorts, silky
boxers, and extreme temperatures.
The front panel incorporates holes for rack mount-
ing, where it will take up two rather lovely rack spaces.
There are two handles fitted on the front panel for easy
transporting.

This icon leads you to in-depth explanations
of features and practical tips. 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-
