Superb, Featuring 300 Watts per channel into 8 Ohms (450 Watts per channel into 4 Ohms).

The ZX-7 is a fully balanced power amplifier 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 and immunity from stray electronic fields and anomalies in the input signal from outside interference. Internally, the ZX-7 utilizes dual massive toroidal transformers and ample filter capacitance.

The ZX-7 also employs heavy-duty, chassis-mounted input and output connectors including balanced audio inputs via RCA or XLR connectors. A trigger input connector (to power on and off with the preamp/processor) allows the amplifiers to be controlled with associated components such as the Lexicon series of preamp/processors.

Equipped with advanced thermal, current, DC and speaker protection, the ZX-7 power amplifier can be matched with most loudspeakers. The ZX-7 also features embedded protection against short circuits, component failures, mis-wiring and internal faults.
