January 15, 2020 -- The Audison design team, headquartered in the Potenza Picena (Italy), spent a long time planning and perfecting the new SR line. 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 entire SR amplifier line. This technology made it possible to reduce the size of the amplifiers while totally preserving the audio performance that characterize each Audison project.
The New SR Line consists of these four models:
- SR 4.300 MAP $ 399.99 85w x 4 @ 4ohms
- SR 4.500 MAP $ 499.99 130w x 4 @ 4ohms
- SR 5.600 MAP $ 549.99 75w x 4 @ 4ohms, and 550w x 1 @ 1 ohm
- SR 1.500 MAP $ 399.99 500w x 1 @ 4ohms, 800w x 1 @ 2ohms, 1000w x 1 @ 1 ohm
- Optional VCR-S1 Remote Volume Control for both models.
Some New Features include:
Built in USS (Universal Speaker Simulator)
When using the high-level inputs, the SR amplifiers can also be appropriately connected to OEM sources featuring the “speaker load detection” function that monitor the presence of a low-impedance load to enable audio outputs.
Complete Controls on Top 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.
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.
Built in Crossovers
Lo-Pass and Hi-Pass 12 dB adjustable (50 Hz to 3200 Hz) filters, providing the ability to build a front + rear system, a multichannel – woofer + tweeter system or a powerful sub + front system.
On the SR 5.600 & SR 1.500 models
24 dB continuous adjustable (50 to 500 Hz) Lo-Pass subwoofer filter. SUBSONIC filter (24 dB - 25 Hz), removes very low subsonic frequencies from music signal to avoid damages to the subwoofer.
