Lexicon NT Series Amplifiers

Congratulations on your purchase of a Lexicon amplifier. Your amplifier has Introduction been designed and manufactured for absolute linearity and stability. Utilizing

a unique Quad-Complementary output stage, the NT Series amplifers produce less distortion than even Class A designs, with higher efficiency and better long term reliability. A wide variety of input and output connections and configu- rations are accommodated, as well as unique features specific to complex multi- channel audio systems.

The amplifiers are not “voiced” to “sound” a certain way. We believe an amplifier’s goal is simple; to amplify the signal, accurately and cleanly, into any load, without imparting any coloration or distortion. Indeed, the distortion components of our amplifiers are near the limits of sophisticated test instru- ments. The amplifier’s sound can best be described as utterly neutral.

While the amplifier’s goal is simple, its job is not. Over 20 years of amplifier research and design have resulted in products that perform flawlessly, year after year after year. Sophisticated engineering, manufacturing, and testing are combined with meticulous craftsmanship and pride. We believe that you will come to pay our amplifer the highest compliment; you will forget about it! The amplifier will quietly, cleanly and reliably perform its job. Enjoy the music, enjoy the movies, forget about the equipment. Thank you for choosing Lexicon.

This manual is designed for installation of any of the five amplifiers models in the Lexicon series: 212, 312, 412, 225 and 501. Whichever model you have selected, we are sure that you will be pleased with its quality and performance.

The 17" model is standard for all models in the NT Series. A 19" rack mount version is available in 120V configurations.

We have designed this manual to provide a brief overview of each amplifier, as well as to provide the information necessary for safe installation and operation. We trust that the time you invest in reviewing these brief instructions will be rewarded by the best possible performance and longevity of your equipment.
