Yamaha, distributed by Radio Parts, has released the XDA-AMP5400RK multi room, 4 zone, 8 channel amplifier.

The amplifier has been designed for custom integration of whole home audio systems. It also serves as a companion amplifier for the Yamaha XDA-QS5400RK to expand speaker coverage and/or increase power output. It can also be used to expand secondary zone speaker coverage for Yamaha AV receivers that have Zone pre outs.

It features eight channels of audiophile-grade Class D amplification, bridgeable and 4-ohm capable, with a ground loop/hum-free circuit design. It also has four audio buses and included jumpers to allow for a wide variety of speaker configurations. The amplifier is also integrator-friendly with its inclusion of audio sensing inputs and IR I/O.

Lastly, it has a lot of flexibility with removable rack ears and a faceplate. The four audio I/O buses can be patched together to handle a wide range of speaker/zone configurations. The amplifier also comes with a set of jumper plugs and cables while the audio outs can be used to connect powered subwoofers or subwoofer amps.
