The AF M12.14 bit features twelve reinforced high-fidelity channels 60 x 12 @4Ω*, 90W x 12 @2Ω* with the audiophile sound of the latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering, and higher tolerance components deliver a sound that exceeds expectations for Class D – all in an amazingly compact package! This is combined with a native DSP operating at 24 Bit/96 kHz, extending the audio band up to 40 kHz and having received the coveted High-Resolution certification. Bridging channel pairs results in 180 x 6 @4Ω*, guaranteeing flexible and powerful performance. Support for the Absolute Volume function of the Audison B-CON ensures maximum bit depth, even with wireless connections! *Output continuous power (RMS) @14.4 VDC, 1% THD, all channels driven.
