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.
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.
