AF M1D 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.

Box Content
Provided cable for AF M5.11 bit and AF M1D with two pairs of labeled cables to connect a single voice coil or dual voice coil subwoofer, or two subwoofers.
Provided in pair. Two stereo RCAs interconnection to connect Forza bit amplifier with after-market sources with PRE-OUT outputs provided with Forza amplifiers.
Accessories
The Audison AFM CLK accessory is specifically engineered for the Audison Forza Max amplifier line. This accessory kit comprises a metal bracket equipped with air flow slots and a cooling fan, which can be securely mounted onto the Audison Forza Max amplifiers.
Key Features:
• Durable Metal Bracket: The sturdy metal bracket ensures reliable support and optimal airflow through strategically placed slots.
• Efficient Cooling Fan: The cooling fan is equipped with a temperature sensor, allowing it to activate only when the amplifier requires additional cooling. This ensures efficient operation and prolongs the lifespan of the amplifier by preventing overheating.
• Temperature Sensor: The intelligent temperature sensor continuously monitors the amplifier’s temperature, activating the cooling fan only when necessary, providing efficient and effective cooling precisely when needed.
The Audison AFM CLK accessory is highly recommended when the amplifier is installed in very tight spaces with limited air circulation, ensuring optimal performance and longevity under challenging conditions.
The Audison AF Link is an accessory cable to connect the DSP OUT outputs of the Audison AF bit amplifiers (amplifiers with integrated DSP) to the PRE IN inputs of the Audison AF D amplifiers.

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