Audison AF C4D 4-Channel Class D Amplifier Fully Bridgeable

The AF companion amplifiers are designed to add powerful amplification channels to AF bit processors amplifiers. Plug-and-play signal input wiring is included that makes connection to AF bit amplifiers simple. AF companion amplifiers are also perfect for use with systems controlled and managed by an independent bit processor, such as a bit One HD. AF companion amplifiers have a "straight wire" architecture, without analog preamplification functions such as crossover filtering, and are intended for use with external processors.

AF M4D boasts four high-fidelity amplified channels 90W x 4 @4Ω*, 150W x 4 @2Ω* with the audiophile sound of the latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering and higher tolerance components deliver sound that goes beyond Class D expectations, in an incredibly compact package! The audio band is extended to 40 kHz, achieving the coveted High-Resolution certification. Bridging pairs of channels produces 300W x 2 @4Ω*, ensuring flexible and powerful performance.

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