Great PA Sound Has Never Been Easier Or Better Looking
Much of the work in putting together a high-performance sound system involves amplifier and speaker selection and setup. Here are a pair of solutions that can take you 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 assemble sound reinforcement systems from modest to massive. They look great, too. So good, in fact, that they can be used as-is in many permanent installations without requiring any cosmetic cover-up. And, of course, theyre more than rugged enough for demanding tour applications as well.
The Case For Built-in Power
Whether for use on the road or in permanent installations, powered speakers offer numerous advantages over their separate counterparts. The most obvious is that you dont need separate external amplifiers or the extra connections required you can plug your mixers outputs directly into the speaker inputs. In a modest-size system this alone can eliminate an entire rack of amplifiers. 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. In the Yamaha MSR400 and MSR800W the internal amplifiers have been ideally mated to their respective speakers in every way possible, delivering reproduction quality that only such stringent matching can achieve.
In this system, the main house speakers are a pair of MSR400s with speaker stands and MSR800W subwoofer, driven directly from the mixers main stereo and mono outputs. The MSR400s feature punchy bass and exceptionally clear midrange that delivers vocals with outstanding quality. The MSR800W subwoofer takes care of the ultra-lows so the audience hears – and feels – the full impact of the music. A second pair of MSR400s is used for stage monitoring, connected via a graphic equalizer for feedback control.

For Sound You Can Feel
The MSR800W powered subwoofer is the perfect companion for the MSR400, 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 cone woofer powered by an ultra-efficient burst 800 watts 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 MSR800Ws dual HIGH PASS outputs, high-pass filtered at 80 Hz through100 Hz, depending on the setting of the cutoff frequency control, with a steep 18 dB/octave cutoff slope.
Visual Clip Indication
Both the MSR400 and MSR800W feature LED power indicators as well as clip indicators that warn of impending clipping. This allows the engineer to make appropriate adjustments to the source level.
