Audison Forza AF M1D Mono Amplifier

Amplifier | 1000 W total power | 1 x 1200 W @ 1ohm | D-class: AF D companion amplifiers are designed to add powerful amplifier channels to AF bit amplifiers. A plug-and-play Input harness is included to make the connection to AF bit amplifiers straightforward. AF D amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso. AF M1D boasts one high-fidelity amplified channel 600W @4Ω*, 1000W @2Ω*, and 1200W @1Ω* 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! AF M1D is the only one in the AF D family that can be used also in standalone mode, thanks to a set of manual controls: 

• Adjustable (and defeatable) low-pass 4th-order crossover filter
• 0-180° polarity/phase switch 
• 45 Hz Bass Boost adjustment 

Combine these functions with the ART DC turn-on from high-level Inputs, the USS speaker-input loading, and the optional VCR-S2 level knob, and this amp can be used to add subwoofers even in systems which lack an Audison AF bit amplifier!

•  Output Continuous Power (RMS) @14.4 VDC, 1% THD, All channels driven.

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.
