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.
Bi-Amplification
The MSR400 is a bi-amplified 2-way system, featuring 400 watts maximum burst
power that drives the 12" cone woofer and 1.75" V.C. 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 virtually unavoidable in conventional passive
crossover networks. Another advantage of this type of system is that power can
be optimally assigned to the low-frequency and high-frequency units for optimum
efficiency as well as smooth, natural balance across the entire audio spectrum.
Wide Input Range & EQ Control
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.
Versatile Placement
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 (theres even a
pole-mount hole provided on the companion MSR800W Powered Woofer). And its
flyable so you can benefit from the unrivalled coverage and positioning
precision that only ceiling suspension can provide.
