high end amplifier For SQ - 100% Made in Italy
Hi members here,
I am willing to let go my Audison LRX2.9 2 channel amplifier which purchased from local distributor last year, I bought RM3250 and willing to let go 50% discount due to need money to change car. Condition still very good, can test in my car for serious buyer only. below is the spect. Thanks! Any one interest please PM me. this is a link

Audison LRX29 Description
LRx 2.9 are powerful stereo amplifiers. Their power supply section and final stages, designed to work also in mono and trimode, insure very high output current, with powers up to 900 W (RMS). AMP constantly check the operating status system and ART function allow automatic turn-on/off when a remote signal isn’t available from the source.
Like in all LRx models, you can use VCRA volume remote control by connecting it to the special SUB VOL socket when you drive the subwoofer in mono. There are endless handling possibilities, for every type of installation.
Tonal accuracy is the best, with clear, detailed trebles and solid, bursting bass, for ultimate performance.

ECI - Easy Common Interface - Connection versatility
Two modules to meet any demands of connection to any source.
The modules, equal for all amplifiers, act as input or output, according to the model, bypass or filtered preout signals.
Besides being interchangeable, these modules are reversible and allow both the standard connection or the one with the contacts facing the amplifier inside.
ECI-H automatically activates ART - Automatic Remote Turn On-Off, which turns on and off the amplifier according to the source, without the need of a remote signal and without troublesome bumps or delays, typical of traditional systems switching off.
It can also generate a preamplified signal on the RCA outputs from the input high level one.
ECI permits to widen every factory system without limits.
Easy Set Up - Easy configuration
Practical examples guide the creation of a system. Choose a system, a simple two channel front or a multiamplified, multichannel one, driven by a single stereo signal or by complex external processors; you will be able to build it through the use of pre-drilled cards and the help of detailed owner’s manuals. Installation is guided step by step, for achieving maximum performance and results. Everybody can configure the most difficult system without mistakes thanks to these diagrams.
SAF - Smart Air Flow - Beyond thermal limits
The cooling system concerns the heat sink exterior and its interior. A fan is in the heart of the circuit; its rotation speed, electronically controlled by AMP, changes according to the amplifier working temperature.
The higher the demanded power is, the more heat will be generated, the faster the fan speed will be. Forced air flow improves cooling; it takes air from the outside and pushes it where it is more needed, until it comes out again through the proper ducts and carries excessive heat with it.
SAF insures maximum thermal capacity and, thus, power. HCI - Hidden Cables Installation
The mistery of disappearing
The installation of an amplifier with protected, hidden
cables is no longer a dream because LRx was
designed for this, too. The amplifier fixing holes are
inside its outline and covered when installation is over.
Power supply terminal blocks can accept cables up to
2 A.W.G. (33 mm2);
their shape has the cable and its jacket bend
of almost 90°. ECI reversibility locates the signal
connectors in an invisible place.
Two special hollows in the bottom
allow the signal cables routing;
cables can be fixed through clips.
AMP - Amplifier Management Processor - Controlling the elements
LRx electronics controls a powerful heart. A microprocessor constantly analyses voltage and current, signal and temperature, to supply the maximum and the best power in every condition and moment. Music best, possible reproduction: this is the goal to achieve. AMP is much more than the amplifier handling system; it activates several
functions which monitor and protect the installation: power supply system, speakers, wiring and source.
The working temperature affects the components functioning; AMP reads its value, electronically carrying out its thermal stabilisation and indicating the achievement of thermal limits while the amplifier can safely go on supplying power. In case of speakers systems which tend to overload the output stage, AMP acts by limiting power supply voltage.
The audio signal dynamics and original quality are never affected, while the amplifier supplies as much power as possible.
MSC - Modular Soundproof Construction - The separation of contents
The amplifier is designed in a modular way. Its motherboard has oversized paths, which are routed not to interfere with the audio signal, and only houses passive power components and service circuits. The connections between output stages and speakers terminal blocks run along the printed circuit board side ends, passing behind the modules where BJT output transistors are assembled. This way the right and left channels of every section are one as far as possible from the others, to the advantage of stereo separation. All the drivers, from power supply to final stages ones, are on SMD modules. The preamplifier/controls/crossover section is built on a special printed circuit board. The separation of signal control circuits from power supply and power ones prevents every possible interference. Power supply stage is PWM stabilised.
Thanks to its high ability of supplying current and to the use of MOSFET’s of 70 A each, it is possible to easily drive even the most difficult loads, with valued tonal accuracy and first-grade acoustics.
Services - The importance of knowing limits Expansion potentialities are endless. ECI modules efficiency is completed by the sockets functionality. When you connect the cables of a factory speaker to SPK ON socket, you activate ART function even if ECI-H input module is not used.
The amplifier will automatically turn on and it will repeat the turn-on signal, which will be supplied to other electronic devices in the system.
When they are configured for driving a subwoofer, all the LRx’s can be adjusted thanks to ESV - External Subwoofer Volume, by connecting VCRA, a volume remote control, to the special SUB VOL socket.
