AF M6D Amplifier | 1320 W total power | 6 x 220 W @ 2ohm | D-class Fully Bridgeable

AF companion amplifiers are designed to add powerful amplifier channels to AF bit processor amplifiers. A plug-and-play signal input harness is included to make connection to AF bit amplifiers straightforward. AF companion amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso. AF companions have a “straight wire” architecture, without analog preamp functions such as crossover filtering, and are intended for use with external processors. AF M6D boasts six high-fidelity amplified channels 135W x 6 @4Ω*, 220W x 6 @2Ω*, with the audiophile sound of the latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering, and higher-tolerance components deliver sound above and beyond the expectation of Class D – in an amazingly compact package! The audio band is extended up to 40 kHz earning the coveted High-Resolution certification. Bridging channel pairs results in 440W x 3 @4Ω*, guaranteeing flexible and powerful performance.
*Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.

Features

  • Improved audio performance and power thanks to the latest generation of ADT (Audison D-Class) technology
  • Unbeatable power/volume ratio up to 0.68 W RMS/cm³ reaching 81% of efficiency
  • Hi-Res compatibility performance, with an extended audio band up to 40 kHz
  • Maximum versatility thanks to the possibility of using the bridging option for each pair of power outputs

Technologies

AF LINK CABLE
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.

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

AF LINK CABLE

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