Yamaha XM 4220 Amplifier

Although stereo is the standard configuration for audio power amplifiers, many applications require more than two channels. The result is that you'll have to purchase multiple amplifiers, and supply the necessary installation space. The Yamaha XM-series Multi-channel Power Amplifiers are the perfect solution. The XM4220 provides four channels, delivering clean power to standard speaker systems or 70.7-volt distributed multi-speaker systems - or any combination. This model features Yamaha's exclusive EEEngine technology for exceptionally high power efficiency, and superior sound quality that is in keeping with Yamaha's high standards. Top-quality professional connectors are used throughout for maximum reliability, and features like rear-panel attenuators and high-pass filter switches afford maximum flexibility.
