POSSIBILITY OF BRIDGING

AF Series complementary amplifiers are designed to add additional powerful gain channels to amplifiers with a signal processor (“AF bit” type). The set includes a plug-and-play signal beam, which makes it much easier to connect to AF bit amplifiers. These amplifiers are also perfect for systems controlled by a standalone signal processor, such as the One HD Virtuoso bit. AF models are distinguished by a “straight wire” architecture (without analog preamplifier functions such as crossovers) and are designed to work with external sound processors. The AF M4D offers four high-fidelity amplification channels (160 W x 4 at 4 Ω* and 260 W x 4 at 2 Ω*),providing audiophile sound quality characteristic of the latest generation of Audison class D technology. Higher switching frequencies,steeper filter slopes and components with higher precision allow you to achieve sound that exceeds typical expectations for Class D amplifiers – all in an extremely compact housing! The frequency response has been extended to 40 kHz, which allowed to obtain the prestigious High-Resolution Audio certificate. Bridged channel pairs achieve 520W x 2 power at 4Ω*, guaranteeing flexibility and impressive performance. *Continuous power output (RMS) at 14,4V DC, 1% THD, all channels driven.
