Yamaha MSR400 Powered PA Cabinet (12 Inch, 300 Watts)
The Yamaha MSR400 Powered Speaker is a bi-amped two-way
speaker cabinet with the power amps built right in! It uses a 225W amp to power
the 12” woofer and a 75W amp to power the 1.75” compression driver.
Traditionally, much of the work in putting together a high-performance sound
system involved getting the proper components and getting them to work together
optimally, especially matching the proper power amplifier with your speakers.
Yamaha has taken a lot of the guesswork out of the process with the introduction
of their MSR400 powered speakers. With a frequency range of 50Hz to 20kHz and a
max. SPL of 121dB, the MSR400 can really fill a room! I/Os include XLR and 1/4”
TRS connections. It is also equipped with a 2-band EQ. The matching 500W MSR800W
powered subwoofer has a built in high pass filter so that you don’t have to use
an external crossover when you use the MSR 400 and the MSR800W together.
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 mixer’s 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.
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 (there’s even a
pole-mount hole provided on the companion MSR800W Powered Woofer). And it’s
flyable so you can benefit from the unrivalled coverage and positioning
precision that only ceiling suspension can provide.
