Owner’s manual
Introduction
Audison has always stood out for the innovations of its products.
Smart ideas, new solutions, unique circuitry functions created for satisfying enthusiasts and
Audison designers’ spirit of perfection.
LRx is a unique project; it derives from THESIS HV venti, a state-of-the-art amplifier, and follows its
main principles, for the best acoustic performance.
LRx is revolutionary, innovative, since various functions are concentrated together in a single
product for the first time.
ECI - Easy Common Interface is an original, universal inputs system sporting interchangeable
modules which can accept low and high level signals. ECI modules reversibility is combined with
HCI - Hidden Cables Installation.
SAF - Smart Air Flow enhances thermal capacity; the heat sink size decreases, cooling increases
and it is possible to get a compact, yet powerful amplifier.
LRx introduces AMP - Amplifier Management Processor, a microprocessor system which handles
and controls the amplifier and which analyses the whole audio system.
MSC - Modular Soundproof Construction, the modular structure and the circuits layout were
designed in order to get the ultimate sound quality.
A covered control panel shows the information it receives by the AMP about the working status;
it has completely independent, bypass crossovers which can be configured in any ways.
The ART - Automatic Remote Turn On-Off function, the Easy Set Up, the ESV - External
Subwoofer Volume and the supplied accessories complete the amplifier.
These unique qualities are completed by digital amplification.
The advantages of great efficiency and low heat production have been achieved solving the
problems of reliability, distortion and inability to drive difficult loads. Audison has developed a D
class amplifier with a 220 kHz clock frequency, more than twice the current standards.
This technique can reproduce the entire sound range, but is strengthened for Subwoofer frequencies.
A performance-enhancing innovative solution with a terrific power impact for endless thrill.
LRx: it is enough to have a look at it, both inside and outside, to install it and listen to it to feel
satisfied with owning something special.
All in one: the LRx Multichannel Theater 3.1MT and 5.1MT meet in a single installation all the
amplification needs for Car Theater multi-channel systems. Three or five high-power channels and
a vigorous Sub section, designed with digital technology, to match an external sound processor.
The interface of the ECI modules, the Auto Turn-ON function and the remote control of the Sub
volume allow to connect the system with original sources, even amplified, and add them the right
dose of watts to live the sound/video event in the front row.
