Introduction - Mackie MR5mk2 Owner's Manual

Introduction

The MR5mk2 Mackie Reference Monitor is the perfect
solution for those ready to step up to a truly professional
monitoring system. The completely re-voiced MR5mk2
features all-new high-end drivers and provides
unmatched frequency response performance in its
category. The MR5mk2's precision Class A/B
amplification (55W LF / 30W HF) offers class-leading
power, tons of connection options and simple acoustic
controls for room correction. Plus, an optimally sized
custom waveguide and minimum-diffraction molded
baffle work in concert to provide superior stereo
imaging and depth. With unbelievable power,
performance and clarity, the MR5mk2 stands alone
in its class.
Investments in Excellence...
The MR5mk2s were designed by our expert
loudspeaker and transducer engineering teams at
Mackie and EAW. These compact studio monitors can be
used in a variety of applications, including small project
studios, surround sound editing, home theater playback,
and desktop audio workstations (DAWs).
High-frequency and low-frequency switches are
provided on the rear panel to adjust the sound of the
monitors to the characteristics of the room. Three types
of input connectors are provided (XLR, 1/4-inch, and
RCA), to interface with virtually any application you
may have.
The result? The MR5mk2 Studio Monitors are extremely
accurate and versatile, with unique controls that allow
you to fine-tune the sound to match your individual
environment precisely. You're gonna love these!
What are they? The Advantages...
The MR5mk2 Studio Monitors are two-way,
bi-amplified, active monitors employing a bass reflex
(ported) design for an extended low-frequency
response. There are many benefits to integrating an
active crossover, power amplifiers, and drivers into a
single cabinet, and we've taken full advantage of these
benefits in the design of the MR5mk2.
• The crossover point is designed so that the high- and
low-frequency drivers are fed only the frequencies
they are best able to reproduce.
• The amplifiers are designed to provide maximum
acoustic output from the speakers, yet minimize
the danger of speaker damage due to overdriving.

• In addition, the amplifiers' gain and frequency
responses are individually hand-trimmed to
compensate for typical manufacturing tolerances
between the drivers and produce a smooth
frequency response from 50 Hz to 20 kHz.
• The connecting wires between the amplifier outputs
and the drivers are kept to an absolute minimum,
so the damping factor of the amplifier isn't
compromised by the resistance of long speaker
cables.
• The acoustic sum of the outputs from the two
drivers are optimized electronically, as well as
physically, so the amplitude response is unity and
the phase difference is minimal.
In short, all the complex interconnected components
in the system are designed to work in harmony with
each other to produce the best possible sound.
All-New Transducers...
The MR5mk2s feature a 5.25-inch high-precision,
low-distortion woofer and a 1-inch neodymium silk
dome tweeter.
The high-frequency driver is mounted on a molded
baffle/waveguide, which reduces diffraction and results
in wide, controlled dispersion of high-frequency sounds.
This widens the "sweet spot" and improves the time
domain characteristics of the system.
Precision Power Amplifiers...
The low-frequency amplifier produces up to 55 watts
continuous before clipping, while the high-frequency
amplifier produces up to 30 watts continuous. Both
amplifiers are Class A/B with power MOSFET outputs
and active protection circuits.
Cabinet Design...
The cabinet is made of MDF with a textured matte-
black finish. Internal bracing increases the strength and
rigidity of the box. An open-cell adiabatic foam material
fills the inside of the box to absorb internal reflections
and dampen standing waves.
