Yamaha MSR-400 powered loudspeaker

The Yamaha MSR400 is a compact and lightweight mains-powered loudspeaker with a surprisingly punchy sound. The Yamaha MSR400 is ideal for use as a stand-alone PA system with either a mic or line input, as a stage monitor or as a club system for DJs or iPod playback. It can be combined with the Yamaha MSR800W powered subwoofer to form a bigger system and individual cabinets can be linked for public address or monitoring from a single source.

Features

400 Watts of Bi-amped Power
The Yamaha MSR400 employs a two-way bi-amplified system in which the low-frequency and high-frequency drivers have their own dedicated amplifiers. The 12-inch cone type woofer and the 1.75-inch high-frequency horn driver deliver total output power of up to 400 watts (LF: 300 watts, HF: 100 watts burst; 300 watts continuous total).

Inputs for a Variety of Sources
The Yamaha MSR400 provides three input connectors; XLR-3-31, XLR-3-32, and phone jacks. All inputs are balanced and connected in parallel. The input level range is from -36 dB to +4 dB, allowing the Yamaha MSR400 to accept output from your mixer as well as other sources such as microphones, synthesizers, or other electronic musical instrument. The control section includes input level adjustment and a two-band equalizer so you can make fine adjustments for optimum matching with your input source.

A Range of Mounting Options
The Yamaha MSR400 can be mounted and positioned in a number of ways to meet the needs of venues or events. It can be placed vertically on the floor, used as a stage monitor, or even mounted on a speaker stand for improved projection. The top surface of the cabinet provides 8-mm threaded holes that facilitate wall or ceiling mounting.

Peak LED for Visual Level Monitoring
In addition to the green LED that lights when the power is turned on, there’s a peak LED that lights red when an input overload occurs. This provides a visual indication of excessive input, allowing you to adjust the input level appropriately.
