Yamaha MSR400 Active PA Speaker

The Yamaha MSR400 Active PA Speaker is the largest speaker MSR range but still remains very light for easy portability. The Yamaha MSR400 is a compact, bi-amplified system delivering 400 watts of built-in power. A 300-watt low frequency power amplifier drives the 12 inch woofer, while a 2 inch titanium compression driver is separately powered with a 100-watt high frequency power amplifier and coupled to a 90 degree x 40 degree constant-directivity horn

Using Yamaha’s proprietary EEEngine Technology, the internal amplifiers maintain efficiency, with reduced weight, low current draw and low heat. The MSR400 provides a wide (50 Hz - 20 kHz) frequency response, uniform coverage and intelligible audio, thanks in part to Yamaha’s Bass Reflex bi-amplified design. A 2-band EQ and master level provide basic, effective tone control and output volume. Connectors include a balanced XLR MIC input, plus balanced TRS phone and XLR LINE inputs. All connections are paralleled, allowing multiple speakers to be daisy-chained. Constructed of high impact polypropylene, the MSR400 weighs 51 pounds, and can be flown, stacked, wall or pole-mounted, or used as a floor monitor. The MSR400 can also be paired with the Yamaha MSR800W Subwoofer for additional low frequency support.
