Audison SR 1.500 - 1-Kanal Verstärker

SR 1.500 - MONO AMPLIFIER WITH CROSSOVER

HIGH PERFORMANCE IN A COMPACT SIZE
We are proud to present the refurbished SR 1.500 (1000 W 1 Ohm), introduced in 1988 and constantly updated with the best available technologies.

Audison_ADT

The Audison design team, headquartered in Potenza Picena (Italy), planned and perfected the new SR line for a long time, making use of the functions with which the latest amplification devices available today are equipped. After numerous hearing tests in a double-blind configuration with a large number of experts and enthusiasts, the research and development team decided to introduce a new D-class technology called ADT (Audison D-Class Technology) for the entire product range this allowed you to significantly reduce the size of the amplifiers while maintaining the audio performance that characterizes every Audison project.

EDGELESS DESIGN

W hen electronic design has taken the Audison Style Center to any aesthetic and functional detail and obtain a compact amplifier made from extruded aluminum with rounded corners, which facilitates the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifier, no internal cooling fans are required, which often lead to noise and dust deposits.

COMPLETE CHECKS ON THE TOP

As is traditional in the tradition, SR amplifiers confirm their vocation to be versatile by including a complete filter section in all models that is suitable for any type of audio system configuration. The controls, which are protected by a satin aluminum plate, are located on the top plate of the amplifier and are easy to reach from above even after installing the product. If the system includes an Audison bit processor, the filter section can be completely excluded.

Audison_USS

Thanks to the integration of Audison USS technology (Universal Speakers Simulator) in the high-level inputs, the SR amplifiers can also be connected to OEM sources with the "Speaker Load Detection" function, which monitors the presence of a low-impedance load activate.

UNLIMITED CONNECTION

All models are equipped with high-level balanced inputs for connection to the output of the OEM head unit speakers and with a low RCA level for the after-market speakers. When using the high-level input, the ART function (Automatic Remote Turn-On / Off) can be activated in order to control the switching on of the amplifiers with the power button of the main unit.

There is also a remote IN / OUT socket that can be used to switch on the control of several cascaded amplifiers if required.

The SR 1,500, SR 4,300 and 4,500 models restore the PRE-OUT signal by using the Speaker-IN input to connect it to OEM sources that are only equipped with amplified outputs, which enables system expansion.
