The Monitor Audio IA750-4 is the best option for larger installations that need pure power. This 2U full width high-power amplifier is easy to install and operate, and it has a full DSP matrix configuration. Its strongest suit, however, is power: four 750 W channels produce the best possible home theater sound. It is the ideal companion for Monitor Audio's THX Ultra certified Cinergy home theater system and can extract the maximum performance from any system. Note: Included is a rack installation kit.
