SR 5.600 Amplifier 1010 W total power 4 x 115 W + 1 x 550 W @ 2ohm D-class Audison SR 5.600 series 5-channel amplifier with crossover and great power packed into ultra-compact dimensions ( 75 W x 4 + 330 W x 1 4Ω)SR line, perfected by taking full advantage of the latest amplification devices. After numerous listening tests with professionals and enthusiasts, the Audison research and development team decided to adopt a new class D technology called ADT (Audison D-Class Technology) for this line of amplifiers, which has made it possible to considerably reduce their size, totally preserving the audio performance that characterises every Audison design.As far as the electronic design is concerned, every aesthetic and functional detail of the Audison SR 5.600 has been taken care of, resulting in a compact amplifier made of extruded aluminium 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 amplifiers, there is no need for internal cooling fans, which often cause noise and dust accumulation.In keeping with tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any kind of audio system configuration. The controls, protected by a satin-finished aluminium panel, are located on the top panel of the amplifier, so that they can 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.Optional remote control VCR-S1 offers the possibility to adjust the subwoofer level (-20 / + 6 dB) to your musical preference.Audison USSThanks to the integration of Audison USS (Universal Speakers Simulator) technology in the high level inputs, the SR amplifiers can also be conveniently connected to OEM sources equipped with the 'speaker load detection' function, which monitors the presence of a low impedance load enabling the audio outputs.Audison SR 5.600 allows multiple connectivityAll models have balanced high-level inputs for connecting to the OEM headunit speaker output and a low-level RCA for after-market speakers. When using the high-level input, the ART (Automatic Remote On/Off) function can be enabled to control the amplifiers' power-up with the headunit's power button. In addition, there is a remote IN / OUT socket to allow control of multiple amplifiers in cascade that turn on when needed.Through the PRE-OUT signal using the Speaker-IN socket it is possible to interface the amplifier with OEM sources that only have amplified outputs, allowing for system expansion.

TECHNOLOGIES Audison D-Class technology ADT uses a switching frequency twice as fast as many other modern Class D amplifiers using very high-tolerance component parts to keep the timing correct even during temperature extremes. The higher switching frequency of Audison Class D moves noise much farther away from the audible band. Audison Class D amplifiers also use a steeper 4th-order analog lowpass filter, rather than the simpler 2nd-order lowpass filters usually used in competing designs. The steeper filter will keep noise much lower in amplitude – which is good for controlling EMI and preventing infrasonic noise from getting to the tweeters. It also keeps phase shift outside the audible range. The cost is higher – twice as many components are needed for a 4th-order filter compared to the usual 2nd-order filter, and each output channel needs its own filter – but Audison determined through exhaustive listening testing that this design was the best-sounding approach. The “All Channels Driven” design philosophy guarantees that the Audison amplifier delivers the rated power on all channels simultaneously. To reach that target, Audison designed the amplifier power supply to handle the cumulative power demand.
