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, they're
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 don't 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.
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.
