Audison SR 5.600, 5-channel car sound amplifier

Audison's design team, based in Potenza Picena, Italy, spent a long time planning and developing the new SR line, making the most of the latest amplifiers available today.

• Power: 75W x 4 + 330W x 1 (4Ω).
• Damping factor @ 1 kHz, 4Ω, 2 VRMS, front and rear 100.
• ADT - Audison D-Class technology.

We are proud to present the renovated SR 5.600 (75 W x 4 + 330 W x 1 @ 4Ω) introduced back in 1988 and constantly updated with the best technologies available.

The Audison design team, headquartered in the Potenza Picena (Italy), spent a long time planning and perfecting the new SR line, taking full advantage of the features that the most recent amplification devices available today are equipped with. After numerous listening tests in a double-blind configuration on a significant sample of professionals and enthusiasts, the R&D team decided to adopt a new D-class technology called ADT (Audison D-Class Technology) for the whole range, which made it possible to reduce the size of the amplifiers considerably, totally preserving the audio performance that characterizes each Audison project.

EDGELESS DESIGN

As for the electronics design, the Audison style center has taken care of every aesthetic and functional detail, obtaining a compact amplifier made of extruded aluminum with rounded corners that ease the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, internal cooling fans are not necessary, which are often the cause of noise and dust accumulation.

COMPLETE CONTROLS ON UPPER PANEL

As per tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any type of audio system configuration. The controls, protected by a satin-finish aluminum panel, are located on the amplifier upper panel, to be easily reached from above even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.

Thanks to the integration of Audison USS technology (Universal Speakers Simulator) in the high-level inputs, the SR amplifiers can also be appropriately connected to OEM sources featuring the "speaker load detection" function that monitors the presence of a low-impedance load to enable audio outputs.

LIMITLESS CONNECTIVITY

All models are equipped with high-level balanced inputs for connection to the OEM Head Unit speakers output and low RCA level for the after-market ones. When the high level input is used, the ART function (Automatic Remote Turn-On / Off) can be enabled to control the switching on of the amplifiers with the head unit switch-on button.

In addition, there is a remote IN / OUT socket to allow the control of multiple cascaded amplifiers switch on when required.

The SR 1.500, SR 4.300 and 4.500 models recreate the PRE-OUT signal by using the Speaker-IN input to interface it with OEM sources only equipped with amplified outputs, allowing the system expansion.
