RX7

About the RX7

The Lexicon RX-7 is a seven-channel power amplifier introduced around 2006, positioned between the more powerful ZX-7 and the smaller GX-7 in Lexicon's lineup. It delivers 200 Watts RMS per channel into 8 ohms and 300 Watts per channel into 4 ohms, featuring a fully balanced topology similar to the ZX-7 but with a smaller footprint and power requirement. The RX-7 supports both balanced (XLR) and unbalanced (RCA) inputs and has seven pairs of gold-plated binding posts for speaker connections. It measures approximately 8 inches high, 17 inches wide, and 18.5 inches deep, weighing about 105 pounds. Sonically, it offers solid bass, a well-composed midrange, and superior high-frequency performance compared to the ZX-7, with a smoother and grain-free high end. It is suitable for driving most home theater speakers and is praised for its delicate and sensible sound quality.
