AF M5.11 bit boasts five high-fidelity amplified channels 100W x 4 + 400W @4Ω*, 150WP x 4 + 600W @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 200W x 2 + 400W @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.

Audison’s completely-new bit Drive PC software can analyze, route, and correct the signal in completely new ways – now you can measure, mix, and finally tune the sound with one powerful tool! The new Graphical User Interface simplifies every control and function, integrating acoustic measurement, and ensuring efficient tuning and great sound! The Acoustic RTA is integrated into the equalizer graph, and is compatible with your USB microphone or sound card. The Final EQ function allows final equalization without damaging the delicate left/right frequency relationships. The six processed preamp outputs are in addition to the eight amplified channels, allowing Forza’s DSP section to manage a larger system easily.

Forza’s eight analog inputs, plus an optical Toslink digital input, support total connectivity even with the most complex OEM systems. If more analog inputs are required, the optional F4IN expansion card adds four additional analog input channels! If a Coaxial SPDIF or a second Toslink SPDIF input is needed, the optional F2O expansion card can be used. Audison’s classic de-EQ process is joined by de-Time and de-Phase capabilities, enabling sound restoration in nearly every OEM system., The electrical signal analysis ensures proper integration and correction for each input and output channel. The built-in universal speaker simulation technology (USS) yields maximum compatibility with any OEM Source, without muting or instability.
AF M5.11 bit includes a set of six high-quality cables supplied with a protective printed strip placed upstream of the Molex connectors to increase the resistance to torsion:

Pre-In with 8 stereo RCAs interconnection for after-market sources with PRE-OUT outputs
Speaker-In with 8 pairs of labeled cables for OEM sources with high-level outputs
Speaker-Out with 4 labeled cables to connect the amplifier to the speakers
Sub-Out with 2 labeled cables to connect the amplifier to one or two subwoofers
Dsp-Out with 6 labeled cables to connect the amplifier to one or more companion amplifiers
Forza Control cable with 2 wires for remote power-on and remote out signal, plus 2 wires for functions programmable on bitDrive software.
