Audison SR 4.300 

SR 4.300Amplifier | 520 W total power | 4 x 130 W @ 2ohm | D-class

Audison SR 4.300 4-channel amplifier with crossover and great power packed into ultra-compact dimensions (85 W x 4 4Ω)SR line, perfected by taking full advantage of the capabilities of the latest amplification devices. After numerous listening tests with professionals and enthusiasts, Audison's R&D 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 4.300 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.

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.

Maximum versatility thanks to the bridging option for each pair of channels. Universal Speaker Simulator technology on high-level inputs for maximum compatibility with any type of Head-Unit OEM Source.
