Description

The ZX-7 features a true balanced topology. Each of its seven channels consists of two amplifier stages, one for each side — both positive and negative — of the wave form. The positive input signal is amplified by the positive amplifier and the negative input signal is amplified by the negative amplifier when a balanced signal is applied to the input. This approach lowers noise, lowers distortion, and eliminates interference from external stray electronic fields. Music reproduction benefits from a cleaner soundstage and increased dynamics, while the presentation of subtle detail is improved appreciably due to the significantly lower noise floor.

Along with its exceptional sonic performance, the ZX-7 is equipped with sophisticated protection capabilities. Advanced optically coupled protection circuitry safeguards the ZX-7 from damage caused by excessive heat, short-circuits, device failures, miswiring, internal faults and reactive loads, plus it protects loudspeakers from DC and frequencies below 10Hz. Because the protection circuitry is optically coupled for each channel, it is completely isolated from the audio signal path — eliminating any potential degradation of the audio signal inherent in traditional protection schemes.

A formidable combination of power and finesse, the ZX-7 is the obvious choice for audio enthusiasts looking for maximum performance from their listening systems.
