Lexicon LX-Series Power Amplifier LX-5 & LX-7

LX amplifiers are designed to meet the highest standards of performance and sound quality. In addition, THX Ultra® certification ensures that the amplifiers meet the highest standards set forth by LucasFilm's Home THX division.


The LX amplifiers include many unique technologies that allow them to deliver exceptional performance, even under extreme operating conditions. The amplifiers feature Junction Temperature Simulation (JTS) advanced thermal protection. An internal JTS computer predicts internal temperatures and protects output transistors from overheating, allowing the amplifiers to achieve maximum performance with a minimum number of output transistors. This design enhances performance and reliability.

In addition to JTS, the LX amplifiers feature thermal protection for each channel and the main power transformer. The amplifiers also provide DC protection for each channel, preventing DC and frequencies below 10Hz from reaching the loudspeakers.

The LX amplifiers offer high power output that can be configured for almost any home theater installation. The LX-7 has seven 200 watt channels and the LX-5 has five 200 watt channels. Channel pairs can be bridged to provide 400 watts in addition to the remaining 200 watt channels. Heavy-duty loudspeaker outputs and selectable balanced or unbalanced audio inputs are
also available.

A rear panel trigger input allows the LX amplifiers to be powered on and off by external devices. A ground lift switch helps eliminate audible hum caused by multiple grounding paths in the system.

Built to Lexicon standards, LX Series Power Amplifiers establish a new benchmark for home theater amplifiers. An unbeatable combination of sound quality, power, flexibility and reliability make the LX Series amplifiers at home in virtually any system.
