Asymmetrical Cabinet Design

Sound bouncing around inside a speaker cabinet can have a significant

effect on the sound that comes out. The biggest problem is standing

waves that commonly occur between parallel surfaces. Standing waves

can interfere with and color the speaker’s output, thus degrading sound

quality. The standard solution is acoustic insulation material inside the

cabinet, which does help, but it doesn’t address the underlying problem

of cabinet geometry. Yamaha has gone the extra mile in designing the

MSR250 and MSR400 cabinets, employing a unique configuration that

eliminates parallel interior surfaces and therefore the root cause of

standing waves. Acoustic insulation is also applied to effectively deaden

the space inside the enclosure. Elimination of unwanted sound inside the

cabinet means that optimum sound can be delivered to where it counts

the most: your audience.

Ferrofluid Cooling

Any technology that involves power also involves heat, and this can result

in compromised performance if heat generation is not effectively

controlled. The current driving a speaker generates heat in the voice coil

that, in extreme cases, can cause the speaker to burn out. But even if the

speaker doesn’t actually burn out, that heat still results in inefficiency and

non-linearity that degrade overall performance. As the power and heat

increase, the resistance of the voice coil increases as well, causing power

compression, a loss in acoustic output that reduces the system’s dynamic

range. This problem is overcome in the MSR100 and MSR250 by placing

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.

Mid-size Live Sound

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.

Small PA

This small and extremely portable system can be set up and taken down in a matter of minutes. It delivers spectacular sound, too.

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

amplifiers have been ideally mated to their

respective speakers in every way possible,

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 ferrofluid-

cooled 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.

High-quality Portable Power

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.

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.

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.

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.

Inputs for a Variety of Sources

The MSR400 provides three input connectors; male and female XLR type connectors and a phone jack. All inputs are balanced and connected in parallel. The input level range is 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 adjustments for optimum matching with your input source.

A Range of Mounting Options

The MSR400 can be mounted and positioned in a number of ways to meet the needs of venues or events. It can be placed vertically on the floor, used as a stage monitor, or even mounted on a speaker stand for improved projection. The top surface of the cabinet provides 8-mm threaded holes that facilitate wall or ceiling mounting.

All-in-one Sound that’s Powerful, Versatile, and Reliable

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.

Sound You Can Feel

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.
