Onkyo today announced its top-of-the-line PA-MC5500 nine-channel THX-Ultra2 Plus certified analog power amplifier that is 8-ohm rated at 150 Watts per channel, and up to 400 Watts dynamic power into 3 ohms. It utilizes Onkyo's exclusive WRAT (Wide Range Amplifier Technology) design philosophy, which proscribes low negative feedback, low distortion, extended frequency response, and a power supply with high instantaneous-current capability. To achieve all this, the PA-MC5500 uses large, custom output transistors in push-pull configuration and massive power supply consisting of a large toroidal power transformer and two 22,000 µF storage capacitors. Despite all this power, the PA-MC5500 preserves the subtle details of the sound with a three-stage inverted Darlington circuit to remove distortion and the use of professional balanced line-level XLR inputs for the optimal interface with its ideal companion, the Onkyo PR-SC5508 9.2-channel Preamplifier/Processor. The 51-lb PA-MC5500 has a rigid, anti-resonant chassis, gold-plated inputs and outputs, plus multi-zone and bi-amp capability to allow full utilization of all channels no mater what the system configuration.
