The PS602 is a 2-channel installed amplifier that allows its total 600 watts to be shared across both outputs. Independently control the output level, EQ, and low-impedance/high-impedance (Low-Z/Hi-Z) settings for each output. Onboard configurable loudspeaker processing and direct access to zone controllers eliminate the need for an additional signal processor in many installations, while outstanding audio performance and reliability are assured with patented technologies inherited from the field-proven PowerMatch® line. This unique set of features and technologies makes PowerShare one of the most versatile high-performance amplifiers available.
