Description
We are proud to present the renovated SR 4.500 (130 W x 4 @ 4Ω) introduced back in 1988 and constantly updated with the best technologies available. 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 characterize each Audison project. 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 aluminium 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 cause of noise and dust accumulation.
Features -
• ADC (Audison D-Class) Technology 2Ω stable output stage ensuring high audio performance in a compact size.
• Extruded aluminum compact design with fanless convection cooling system.
• Balanced high-noise rejection input speaker-In (for OEM head units) and RCA-In (for Aftermarket head units) inputs.
• ART (Automatic Remote Turn-On/Off) automatically turns on/off the amplifier when the OEM head-unit turns on/off (can be enabled/ disabled, with Speaker-In inputs).
• Pre-outs, also available when using Speaker-In level inputs.
• Mono operation mode (selectable) to create a sub + front three channel system or a powerful two-channel system.
• Optional VCR-S2 Remote Volume Control (Sold Separately)
