The Audison SR 4.500 Amplifier is for the SR Line of Audison, featuring high power amplifiers with a compact design. The amplifier is 2 ohm stable and has the following outputs: 125W x 4, 130W x 4, 220W x 4, 120W x 2 + 480W x 1, 220W x 2 + 440W x 1, 450W x 2. SR 4.500's compact design and extruded aluminium chassis with rounded corners, makes it easy to install in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifier, internal cooling fans are not necessary, which are often cause of noise and dust accumulation. 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.
