Audison Afm4d Forza Line Amplifier

Description    
Amplifier | 1040 W | 4 x 260 W at 2 ohm | 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 harness is included to make connection to AF bit amplifiers straightforward. AF companion amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso. AF companions have a straight wire architecture, without analogue preamp functions such as crossover filtering, and are intended for use with external processors. AF M4D boasts four high-fidelity amplified channels 160Wx4 at 4 Ohm*, 260Wx4 at 2 Ohm* 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. The audio band is extended up to 40 kHz earning the coveted High-Resolution certification. Bridging channel pairs results in 520Wx2 at 4 Ohm*, guaranteeing flexible and powerful performance.
