ABOUT THE ZX-7 AND RX-7
Congratulations and thank you for purchasing your new Lexicon Power Amplifier. This is a reference-quality amplifier designed to meet the highest standards of power and performance under the most extreme operating conditions. Equipped with advanced thermal, current, DC, and speaker protection, your new amplifier delivers reliable and exceptional performance with most loudspeakers, including mismatched, reactive, and unusual loads. With embedded protection against short circuits, component failures, mis-wiring, and internal faults, the incredible power and wide-ranging flexibility of the ZX-7 and RX-7 amplifiers confirm that they are at home in the most sophisticated and demanding home theaters.
Both the ZX-7 and RX-7 are fully balanced power amplifiers from input to output with completely symmetrical circuit design. In other words, each channel consists of two complete amplifier circuits; one driving the positive input signal and the other driving the negative input signal. With 7 channels, this translates into 14 separate amplifier circuits per chassis. The advantage of this topology over single-ended designs is that it exhibits lower noise, lower distortion, immunity from stray electronic fields and anomalies in the input signal from outside interference. This results in significant audible benefits including increased overall clarity and more pronounced differences between soft and loud passages. Internally, the ZX-7 and RX-7 both utilize two massive toroidal transformers and lots of filter capacitance to ensure rock-solid low- frequency reproduction and ample power reserves.
The ZX-7 delivers 300 Watts per channel into 8 Ohms, while the RX-7 delivers 200 Watts per channel into 8 Ohms.
Equipped with gold-plated speaker output connectors, the rear panel includes balanced or unbalanced audio input via RCA and XLR connectors. A trigger input connector allows the amplifiers to
be controlled with associated components such as the MC-12HD or MC-8 Digital Controllers. The ZX-7 and RX-7 amplifiers include advanced optically coupled protection for each channel.
In order to receive the maximum peak performance from your Lexicon amplifier, please take a few minutes and completely read this manual. This important information will help you make certain that these Lexicon amplifiers are properly configured for operation with the rest of the equipment within your system.
