Audison AF M4D 4-Channel High-Resolution Amplifier Forza Line with Maximum Power of 1040 Watts

AF amplifiers are designed to add powerful amplification channels to processors in the same series (the package includes a plug-and-play signal input wiring for simplified connection). Complementary AF amplifiers are also perfect for use with systems controlled and managed by an autonomous bit processor, such as a bit One HD Virtuoso. They have a "straight wire" architecture, without analog preamplification functions such as crossover filter, and are intended for use with external processors.

Audison AF M4D boasts four high-fidelity amplified channels 160W x 4 @4Ω*, 260W x 4 @2Ω* with the audiophile sound of latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering and higher tolerance components deliver sound above and beyond Class D expectations, in incredibly compact dimensions! The audio band is extended up to 40 kHz gaining the coveted high-resolution certification. Bridging of channel pairs produces 520 W x 2 @4Ω*, ensuring flexible and powerful performance.

*Continuous output power (RMS) at 14.4 V DC, 1% THD, all channels driven.

AF M4D Features

  • Improved audio performance and power thanks to latest generation ADT (Audison D-Class) technology
  • Unbeatable power/volume ratio up to 0.68 W RMS/cm³, with 83% efficiency.
  • Hi-Res compatibility performance, with audio band extended up to 40 kHz
  • Maximum versatility thanks to the possibility of using the bridging option for each pair of power outputs
