Lexicon RX-7 Seven Channel Amplifier

From the manual: RX-7 is a 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 RX-7 utilizes two massive toroidal transformers and lots of filter capacitance to ensure rock-solid low frequency reproduction and ample power reserves. 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 RX-7 amplifier includes advanced optically coupled protection for each channel.
