Audison AF C4.10 bit 4-Channel DSP Amplifier

The Audison AF C4.10 bit is a compact four-channel car amplifier with an integrated 10-channel DSP platform. It is designed for systems that need both clean amplification and detailed signal tuning from one chassis. Four amplified channels power speakers directly, while six DSP-controlled preamp outputs support expansion with external amplifiers.

Rated at 90 watts RMS per channel at 4 ohms, the AF C4.10 bit is suited to actively powered front stages, upgraded door speakers, and multi-speaker OEM integration projects. It can also deliver 150 watts RMS per channel at 2 ohms. For higher-output applications, channel pairs may be bridged for 300 watts RMS x 2 at 4 ohms.

The built-in DSP operates at 24-bit/96 kHz and supports an extended audio band reaching 40 kHz. Its processing tools include crossover filtering, equalization, time alignment, phase control, and real-time audio monitoring. This gives an installer the flexibility to tailor the system for vehicle acoustics and speaker placement.

Audison D-Class amplification combines compact packaging with a rated 81% efficiency at rated power. The amplifier has a 10 Hz to 42 kHz bandwidth and a 0.03% THD figure at 1 kHz, 4 ohms, and 70% rated power. Its 600-watt total RMS capability provides useful headroom for a carefully matched speaker system.

Integration options include eight high-level inputs, eight low-level inputs, a TOSLINK optical S/PDIF input, and six DSP preamp outputs. The high-level inputs support installation with many factory audio systems, while the optical input accepts stereo PCM signals up to 192 kHz/24-bit. Optional expansion modules can add four high-level inputs or a second optical/coaxial digital input.

Key Features

• Four-Channel D-Class Amplifier: Delivers 90 watts RMS x 4 at 4 ohms or 150 watts RMS x 4 at 2 ohms.
• 10-Channel DSP Platform: Combines four amplified outputs with six DSP-controlled preamp outputs for system expansion.
• Bridgeable Channel Pairs: Pairs channels 1/2 and 3/4 for 300 watts RMS x 2 at 4 ohms.
• 24-Bit/96 kHz Processing: Provides high-resolution DSP processing with an audio band extending to 40 kHz.
• Flexible Signal Integration: Accepts speaker-level, RCA preamp-level, and optical S/PDIF source signals.
• Advanced Tuning Controls: Includes EQ, crossover, time alignment, phase adjustment, and RTA monitoring tools.

Design & Installation

The AF C4.10 bit uses a compact D-Class platform measuring 200 x 134 x 47 mm and weighing 1.38 kg. Its integrated DSP and amplifier architecture helps reduce the number of separate components required in a tuned audio system. A built-in status logo indicates operating and protection conditions.

Professional installation is recommended because the amplifier requires correct power, ground, speaker, and source wiring as well as DSP configuration through Audison bit Drive software. Use it as a four-channel active amplifier, bridge it for a two-channel higher-power setup, or add external amplification through the six-channel DSP output. It includes cables for USB connection, control, DSP output, speaker output, preamp input, and speaker-level input.
