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.


Maximum versatility thanks to the bridging option for each pair of channels.


According to the definition of Hi-Res audio provided by JAS (Japan Audio Society), this amplifier exceeds the above 40 kHz bandwith analog requirement.


Universal Speaker Simulator technology on high-level inputs for maximum compatibility with any type of Head-Unit OEM Source.
