The RX-7 is ideally suited to drive high-quality home theater and multi-channel music systems. With low distortion and quiet operation, it achieves exceptional refinement of fine details and resolution of low-level sonic nuances.


With a rated output of 200 watts into seven channels, the RX-7 has more than enough power to drive almost any system to reference levels with ease.
Equipped with gold-plated speaker output connectors, the rear panel includes selectable balanced XLR and RCA input connectors. A trigger input connector allows the RX-7 amplifiers to be controlled by a preamp/processor such as the Lexicon MC-12HD or MC-8. The RX-7 employs the same advanced optically coupled protection circuitry found in the ZX-7, keeping it and associated equipment safe during adverse operating conditions.
Designed for the enthusiast, The RX-7 is the perfect complement to our award-winning Digital Controllers and Disc Transports, providing both power and refinement for today's most advanced listening systems.
