There is an independant amplifier for each of the 12 channels which feature latest digital amplifier technology for superb sound along with cooler running and reliability. Each channel gives 30 watts of power to an 8 ohm speaker, and for more output, channel pairs can be bridged, providing 120 watts output (8 ohms), ideal for options such as driving in-wall subwoofers. The front panel controls simplifies configuration, level setting and other adjustments while the rear panel's Ethernet IP port provides web-enables setup and configuration with an RS-232C serial port for additional control options.
