For commercial environments, 70V multi-channel amps can provide power to 12 zones or 24 speakers mono (70V) or six stereo zones (8/4 ohm) and are a great choice for retail stores, malls, restaurants, museums, and outdoor sound systems. A 12-channel multi-channel audio amplifier is a popular choice for whole house audio systems and can control up to six zones or 12 speakers for superior sound playing room to room. For example, a 5-channel multi-zone amplifier is a great choice for 5.1 surround sound systems because it delivers power to left, right, center, and rear surrounds, so you’ll experience action thrillers with sound quality that rivals commercial movie theaters. The pinnacle of performance in Rotels superb multichannel power amplifier range, the RMB-1585 features 5 x 200 Watts to drive even the largest home theater. Power output varies but decreases as channels increase.

Ideal for whole house audio and home theater systems, these versatile amps typically start at five channels and can go as high as 12 channels. These channels allow you to distribute power to multiple places and adjust volume and control settings from one centralized location. The power supply unit is the heart of the amplifier. On the front panel there was only the power switch and on the rear panel were the Neutrik XLR balanced input connectors and the Elecaudio speaker connectors. In this case I used a 17 and 2U high chassis.

Multi-zone amps, however, include discrete power sources or “channels” with separate input and output connectors. TOA Digital Amplifier technology redefines the very concept of amplifiers. By the other hand, there is the 9-channel power amplifier. The job of a multi-channel amplifier, like all amps, is to provide clean, reliable power to speakers and other passive components.
