RX-7 x 300w Endstufe



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 & Disc Transports, providing both power and refinement for today's most advanced listening systems.
