Citation7.1 THX Certified Multichannel Power Amplifier harman/kardon Power for the digital revolution Harman International SNC - Harman Consumer International 2, route de Tours 72500 Chteau du Loir FRANCE RadioFans.CN Features User-Configurable Outputs: The Citation 7.1 may be used as a four, three or two-channel amplifier, with audiophile quality in all configurations. This flexibility permits you to configure power levels to meet specific system requirements upon initial installation and in later system modifications. High Current Design: Delivers full power to speakers even when matched with complex impedance loads from various speaker configurations. Low Negative Feedback: Improved sonic quality with almost total freedom from TIM (transient intermodulation distortion), THD (total harmonic distortion) and IMD (intermodulation distortion). Quad Power Supply: Four (4) separate power supplies, one for each output channel, eliminate crosstalk among channels and provide the highest possible performance in bridged modes. Power-up Sequencing: When controlled by the remote turn-on system in the 5.0 AV Controller, 7.1 Multi-channel Power Amplifiers in multiple amplifier systems turn on sequentially, each at a slightly different time, reducing power surges in a homes electrical system. Ultrawide Bandwidth Design: Delivers all the subtleties of the source material, even inaudible harmonics that contribute to sonic performance. A Citation design and engineering hallmark. Oversize Heat Sinks: Fan-free convection cooling assures high system reliability and quiet operation. THX Certified: The Citation 7.1 Multichannel Power Amplifier meets or exceeds THX TM standards for sonic performance and is compatible with other THX certified components.
