The top-notch sound quality you can expect from Audison

The AF C4.10 bit features four high-quality amplified channels 90W x 4 @4Ω*, 150W x 4 @2Ω*, with the ultimate sound quality of the latest generation of Audison D-Class technology. Higher switching frequencies, steeper filtering and higher tolerance components produce sound that exceeds Class D expectations in an amazingly compact package! This, combined with a DSP operating at 24 bit/96 kHz, extends the scale to 40 kHz and has earned the coveted Hi gh- Res olution certification. Combining channel pairs delivers 300 W x 2 @4Ω, ensuring flexible and powerful performance. Support for Audison B-CON's Absolute Volume function ensures maximum bit depth even with wireless connections!

*Output continuous power (RMS) @14.4 VDC, 1% THD, all channels driven.

Next-generation control options and sound management

Audison's all-new bit-PC software can analyze, route and correct your signal in completely new ways - now you can measure, modify and finally tune your sound with one powerful tool! The new graphical user interface simplifies every control and function, integrates acoustic measurement and ensures efficient tuning and excellent sound! Acoustic RTA is integrated with an equalizer graph and is compatible with your USB microphone or sound card. The Final EQ function allows for final equalization without damaging the delicate left/right channel frequency relationships. Six processed preamp outputs in addition to four amplified channels, so the Forza DSP section can easily manage a larger system.

Advanced OEM integration capabilities

Forza's eight analog inputs plus an optical Toslink digital input support full connectivity with even the most complex OEM systems. If more analog inputs are needed, the optional F4IN expansion card adds four additional analog input channels! If 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 combined with de-Time and de-Phase features, allowing the original sound to be restored in almost all OEM systems. Electronic signal analysis ensures proper integration and correction for each input and output channel. Built-in Universal Speaker Simulation (USS) technology provides maximum compatibility with any OEM source without muting or instability.

The AF C4.10 bit includes six high-quality wire harnesses with separate strain relief in front of each Molex connector:

1. 8 RCA Pre-In connectors for connecting aftermarket sources
2. 8 speaker-level connections for connecting the original source
3. Speaker-Out with 4 labeled cables for connecting the amplifier to the speakers
4. DSP-Out with 6 labeled cables for connecting one or more additional amplifiers
5. Forza Control cable with 2 wires for remote start and remote exit signals and 2 wires for functions programmable with bitDrive software.
