an advanced ferrofluid in the voice coil gap, where it serves to conduct
heat away from the voice coil with much greater efficiency than air. The
results are smooth, natural frequency response and dynamics as well as
stable performance even under heavy use.

Compact Solutions
for Superior Sound and Convenience
Powered speakers offer many advantages over their
passive counterparts, whether used on the road or
in permanent installations. You don’t need separate
amplifiers or the extra cables and connections
required, so setup is fast and easy while reliability is
significantly improved. The ability to plug directly
into the speaker inputs can eliminate an entire rack
of amplifiers in a modest-size system. But the
benefits go beyond mere convenience. Optimum
matching of amplifiers and speakers involves much
more than simple impedance figures, and can be a
formidable engineering task given the vast number
of choices available. The Yamaha MSR-series power
High-quality Portable Power
All-in-one Sound that’s Powerful, Versatile, and Reliable
The MSR250 delivers the ideal blend of power, performance, features, and portability for an exceptionally wide range of
applications. A newly designed class D amplifier delivers 250 watts of clean, dynamic power via a high-performance
10-inch cone woofer and 1-inch titanium-dome compression driver that match up perfectly for smooth, uncolored
response from 55 Hz to 20 kHz. The woofer has an oversized 2.5-inch aluminum voice coil—a size you’d normally see on
a 15-inch woofer—that contributes to outstanding sound and durability. With all this power and performance the big
surprise is how light and manageable this advanced powered speaker is.
The MSR100 fills a variety of sound reinforcement and stage monitor needs in one lightweight package: mixer, power
amplifier, and speaker system in a single, compact unit that’s perfect for small events and club gigs. Mix the output
from a CD player, rhythm machine and/or keyboard with your voice, for example, without having to use a separate mixer
or power amplifier. Two-band EQ gives you further control over the final sound. The built-in 100-watt power amplifier
delivers plenty of punch so you’ll be heard with full dynamic range and clarity. An 8" custom woofer handles the low
frequencies, while a 1" titanium diaphragm compression driver delivers the highs. For larger events
the MSR100’s link out jack can be used to connect multiple units for higher power and
expanded coverage. A variety of mounting options allow pole mounting, ceiling
suspension, or wall mounting, and you can safely stack multiple units on the stage.
Versatile Dual-channel Input Configuration
For extra input flexibility the MSR250 features dual input channels, each with it’s own low and high equalizer controls
and level control. The signals from the two inputs are mixed and delivered via the MSR250 speakers as well as the
rear-panel line out connector, allowing convenient linking to other speakers or audio devices for easy system expansion
(the MSR250 is a perfect expansion speaker for Yamaha’s STAGEPAS 250M compact sound system).
Input 1 has balanced XLR and phone jack connectors that accept
microphone or line input, and input 2/3 is actually a mixing input in
its own right with phone jack and two pin jack connectors.
Sound You Can Feel
Built for Heavy Duty Use
Although it’s lightweight and easy to handle, the MSR250 is
exceptionally durable and will take the most demanding tours
in stride. It’s also designed to be used in a variety of situations,
including normal upright and wedge-style floor monitor
operation. There’s also a built-in pole-mount receptacle for
convenient stand mounting.

The MSR800W powered subwoofer is a perfect companion for the MSR400, MSR250,
or MSR100 extending the low end and completing the musical spectrum for maximum
punch and impact. The high-quality birch plywood bass-reflex cabinet houses a 15" cast
frame woofer powered by an ultra-efficient 800 watt (max) amplifier, a configuration that
can deliver the elusive 40 Hz through 120 Hz frequency range with precision and
authority. Two balanced XLR connectors are provided for connection to the source,
and that same signal can be directly passed on to the main speakers via a pair of XLR
“THRU” outputs. Alternatively, the main speakers can be fed by the MSR800W’s dual
“HIGH PASS” outputs, high-pass filtered at 80 Hz through 100 Hz, depending on the
setting of the cutoff frequency control, with a steep 18 dB/octave cutoff slope.

delivering reproduction quality that only the most
stringent matching can achieve. There are also a
significant number of Yamaha refinements that put
these extraordinary powered speakers in a class of
their own, including an original cabinet design that
eliminates internal standing waves and ferrofluidcooled voice coils for superior stability and linearity.
The MSR250, MSR400 or MSR100 powered
speakers can be used alone or in combination
with the MSR800W powered subwoofer to create
sound reinforcement systems from modest to
massive that will sound superb while delivering
the power and coverage you need for success in
just about any venue or at any event. They look
great too, and can be used as-is in many
permanent installations without requiring any
cosmetic cover-up. They’re more than rugged
enough for demanding tour applications as well.
Application Examples
Brawn Meets Beauty
The MSR400’s authoritative sound and refined appearance give it both brawn and beauty,
making it a great choice for a wide array of performing and live-sound situations. The
MSR400 employs a two-way bi-amplified system that delivers a total of 400 watts to the
12-inch cone type woofer and the 1.75-inch high-frequency horn driver. In addition to the
green LED that lights when the power is turned on, there’s a peak LED that lights red
when an input overload occurs. This provides a visual indication of excessive input,
allowing you to adjust the input level appropriately.
Mid-size Live Sound
Small PA
This system delivers plenty of power as well as majestic bass with a
pair of MSR400 powered speakers connected via the THRU
outputs of an MSR800W subwoofer. A pair of MSR100 powered
speakers serve as floor monitors for the performers.
This small and extremely portable system can be set up and taken
down in a matter of minutes. It delivers spectacular sound, too.

The MSR400 provides three input connectors; male and female XLR type connectors and

from -36 dB to +4 dB, allowing the MSR400 to accept output from your mixer as well as
other sources such as microphones, synthesizers, or other electronic musical instrument. The
control section includes input level adjustment and a two-band equalizer so you can make fine
