Lexicon, Inc., a Harman International company, announces a new series of Power Amplifiers designed to complement the MC series of Digital Controllers. The series consists of 3 models, all of which feature 7 channels. There is the flagship ZX-7, with 300 Watts per channel, the RX-7 with 200 Watts per channel, and the GX-7 with 125 Watts per channel.

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 utilize dual massive torroidal transformers and ample filter capacitance to ensure rock-solid low-frequency reproduction and ample power reserves.

“Our strategy was to offer the market a better, best, ultimate range of 7-channel power amplifiers to address differing system needs and to complement our line of Digital Controllers,” commented Andrew Clark, VP Sales and Marketing for Lexicon. “The GX-7 is intended for smaller rooms or for systems utilizing speakers with high sensitivity and is a great choice to match up with a Lexicon MC-4 or MC-8 Digital Controller. The RX-7 is a significant step up from the GX-7 in terms of sound quality and power and is fully balanced from input to output. It is intended for small or medium sized rooms or driving speakers that have lower than normal sensitivity. The ZX-7 is intended for larger rooms, driving speakers with low sensitivity, or for those who simply demand the best. Both the ZX-7 and the RX-7 are right at home with any of Lexicon’s Digital Controllers,” concluded Clark.

All three of the new power amplifiers feature heavy-duty, chassis-mounted input and output connectors. The rear panel also features a trigger input to power on and off with the preamp/processor, and handles that facilitate easier installation and rear-rail rack mounting if desired.

The GX-7 is targeted to begin shipping in October at $2,999. The RX-7 is targeted to begin shipping in November at $5,999. The ZX-7 is targeted to begin shipping in December at $7,999.

Lexicon MC-12 HD Music And Cinema Digital Controller
The MC-12 HD brings HDMI (High Definition Multimedia Interface) to the world’s leading pre-amp/processor. Featuring six HDMI inputs, one HDMI output with onscreen display, and up-conversion of composite and S-video inputs to component video output, the MC-12 HD can now interface with HDMI equipped sources and displays.

Complementing its HDMI switcher, the MC-12 HD includes a broadcast-quality analog video switcher with up-conversion to component video. The ultra-wide bandwidth component video switcher accepts analog component video signals, including all HDTV signals, while a composite and S-video switcher accepts high-quality NTSC, PAL and SECAM video signals. The MC-12 HD also includes Serial RS-232 communication capabilities to support third party integrated control systems.

Designed to match the innovative industrial design of Lexicon’s award winning home theater products, the MC-12 HD is a reference-quality, 12-channel digital controller with built-in digital audio processing, 12 configurable inputs and 3 zones. It offers an intuitive user interface with advanced audio technologies including automatic room calibration as well as Logic 7 and the most popular surround decoding formats. Available in balanced and unbalanced versions, the MC-12 HD continues to redefine the reference standard for multi-channel systems.

The feature set of the MC-12 HD includes:
• Twelve channels, twelve configurable inputs, and three zones
• Six High Definition Multimedia Interface (HDMI) inputs
• Up-conversion of composite and S-Video inputs to component video output
• Automatic speaker distance and output level calibration
