Audison 12-Channel Amplifier with DSP - AF M12.14 bit



Online Only

AF M12.14 bit boasts twelve high-fidelity amplified 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 sound above and beyond the expectation of Class D – in an amazingly compact package! This is combined with native DSP working at 24 bit/96 kHz, extending the audio band up to 40 kHz and earning the coveted High-Resolution certification. Bridging channel pairs results in 180 x 6 @4Ω*, guaranteeing flexible and powerful performance. Support for the Audison B-CON’s Absolute Volume function guarantees maximum bit depth, even with wireless connections! *Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.

FEATURES

  • Improved audio performance and power thanks to the latest generation of ADT (Audison D-Class) technology
  • Unbeatable power/volume ratio up to 0.68 W RMS/cm³ reaching 82% of efficiency
  • Next-generation bit Drive software platform
  • Hi-Res compatibility performance, with an extended audio band up to 40 kHz, made possible by and DSP working operation at 24 bit/96 kHz
  • Maximum versatility thanks to the possibility of using the bridging option for each pair of power outputs
  • Up to 14 output channels (12 amplified, 2 native pre-outs) controlled by the DSP to expand the system with other amplifiers
  • 8 high/low-level inputs (and an optical Toslink digital input) support total connectivity even with the most complex OEM systems
  • Extension card slot (additional 4 analog or 1 digital inputs)
  • Electrical signal analysis for each input channel ensures proper integration and correction
  • Acoustic analysis (with your USB microphone) integrates the response graph into the equalizer display. This ensures efficient tuning and great sound!
  • Advanced signal routing options allow the technician to go beyond the predefined system definitions in the Configuration Wizard
