Audison AF M4D - 4-channel amplifier

Amplifier | 1040W | 4 x 260W @ 2 ohms | 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 cable is included to simplify connection to the AF bit amplifiers. AF Companion amplifiers are also perfect for use with systems powered by a standalone bit processor, such as: B. a bit One HD Virtuoso, can be controlled and managed. AF companion amplifiers have a "straight-wire" architecture without analog preamp functions such as crossover filtering and are intended for use with external processors. The AF M4D has four high quality amplified channels with 160W x 4 @4Ω*, 260W x 4 @2Ω* with the audiophile sound of the latest generation of Audison D-Class technology. Higher switching frequencies, steeper filtering and higher tolerance components deliver sound that exceeds Class D expectations - in an amazingly compact package! The audio band has been expanded up to 40 kHz, earning the coveted high-resolution certification. Bridging channel pairs results in 520W x 2 @4Ω*, guaranteeing flexible and powerful performance. *Continuous Output Power (RMS) @14.4 VDC, 1% THD, all channels powered.
