Great PA Sound Has Never Been Easier — Or Better Looking!

If you've ever put together a high-performance sound system you know that it involves careful amplifier and speaker matching and configuration. Yamaha has taken care of that so you can get directly to great sound without the usual complications. The MSR400 powered speaker can be used alone or in combination with the MSR800W powered subwoofer to build any sound reinforcement system from modest to massive. They look great, too! In fact, they are so attractive that they can be placed as-is in many permanent installations without requiring any cosmetic cover-up. And, of course, they’re more than rugged enough for demanding tour applications as well.

Yamaha MSR400 powered speaker at a Glance:

• Powered loudspeakers give you matched components without the hassle
  
• Clear, clean highs and mids plus full bass
  
• Bi-amped system with phase-accurate crossover design
  
• Connect almost any source without fear!
  
• Easy to set up alone or with sub

Powered loudspeakers for matched components without the hassle
Whether for use on the road or in permanent installations, MSR400 powered speakers offer numerous advantages over separate components. The most obvious is that you don’t need separate external amplifiers or the extra connections they require – you can plug your mixer’s outputs directly into the speaker inputs. In a modest-size system this alone can eliminate an entire rack of amps. But there are sonic advantages as well. 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.

Clear, clean highs and mids plus full bass
The MSR400s feature punchy bass and exceptionally clear midrange that delivers vocals with outstanding quality. Add as many pairs of MSR400s as you need used for a scalable main system or stage monitors.

Bi-amped system with phase-accurate crossover design
The MSR400 is a bi-amplified 2-way system, featuring 400 watts maximum burst power that drives the 12" cone woofer and 1.75" compression driver. Frequency division is accomplished prior to the power amplifiers via a line-level electronic crossover. This eliminates the problems with loss, distortion, and phase that are normally unavoidable in conventional passive crossover networks. Another advantage of the MSR400 system is that power can be optimally assigned to the low-frequency and high-frequency drivers for optimum efficiency as well as smooth, natural balance across the entire audio spectrum.

Connect almost any source without fear!
The MSR400 accepts nominal input levels ranging from –36 dB to +4 dB, meaning that you can directly connect any source from microphones to professional line-level gear. Three parallel-connected connectors are provided – two balanced XLR-type connectors and one balanced phone jack – that can be used as either inputs or parallel outputs. The MSR400 also features an input level control for matching with the source signal. Low and high EQ controls can be used to adjust the respective bands over a plus-or-minus 3dB range.

Easy to set up alone or with sub
Speaker placement is as much a performance issue as it is a convenience and aesthetic issue. Proper placement will give you optimum sound as well as coverage while being as unobtrusive as possible. Of course, the more options you have the better. The MSR400 can be stacked or pole-mounted on a sub. And the MSR400 is flyable so you can benefit from the unrivalled coverage and positioning precision that only ceiling suspension can provide.
