Product Description


Yamaha MSR400

The MSR400 is a 400-watt powered loudspeaker built to produce clean, powerful sound in a compact package. Using separate amplifiers for high and low frequencies allows precise control and extended low frequency punch.

The sturdy, lightweight enclosure can be used as both a main speaker or on the floor as a wedge-type monitor.

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 (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.
