Built-in Bi-Amplified Power

Bi-amplified power provides the best possible performance since the amplifier can be designed to work specifically with the speaker to which it is connected. This system also generates less distortion thus delivering cleaner sound than a conventional loudspeaker system. The MS400 utilizes built-in bi-amplified power for optimum sound performance.

In the MS400, a 300-watt low frequency power amplifier is utilized to drive the 12-inch woofer. The system's 2-inch titanium diaphragm compression driver is separately powered with an 100-watt high frequency power amplifier. The system takes advantage of Yamaha's proprietary EEEngine Technology to deliver high quality audio performance with greater efficiency while reducing current draw, heat and weight.

Wide Sound Dispersion

The MS400 delivers uniform coverage of high frequencies through the use of constant directivity horns in conjunction with their 2-inch high requency drivers. The horn delivers a 90ox40o dispersion for optimum audience coverage.

The SW500 Powered Subwoofer for Extended Lows

The SW500 Powered Subwoofer makes adding massive bottom end to your sound system an easy operation. Built into the plywood bass reflex enclosure is a 500-watt power amplifier that drives the single 15-inch woofer. The SW500's power amplifier also utilizes Yamaha's EEEngine Technology for greater performance and efficiency with low current draw, low heat and reduced weight. A pole mount is also built-in to the top of the SW500 to allow mounting of a MS400 on top of the SW500.

Mixer and Connections

The MS400 features a simple but effective mixer that is built into the rear of each unit. The mixer supplies independent MIC and LINE inputs, complete with a separate gain control on each input, plus a two-band EQ (Low, High) and a Master Volume control. Balanced XLR jacks are provided for both the MIC and LINE inputs with a 1/4-inch Phone connector also supplied on the LINE input. A parallel output jack sends the LINE signal to other speakers for convenient daisy chaining of multiple speakers.

Connection of the sound source to the SW500 is via two channel XLR inputs. The same signal can be routed directly to the main speakers via two channel XLR outputs (thru) or via two channel XLR outputs equipped with high pass filters (100Hz). The unit is also equipped with a variable high cut frequency control to optimize integration of the subwoofer into a variety of sound systems.

Easy and Versatile Setting

The MS400 provides the user with a number of ways in which to place the speakers. Both models are flyable so you can suspend them from the ceiling, stackable so you can stack them on the floor, and pole mountable so you can mount them on speaker stands or to a pole attached to the SW500 Powered Subwoofer's built-in pole mount. Optional mounting brackets allow the MS400 to be mounted on the wall or from the ceiling. They'll even lie on their sides for use as floor monitors when needed.

Let Your Ears Decide
