Audison Forza AF C4D

Audison Forza AF C4D - 4-Channel Class-D Amplifier with High-Res Bandwidth and 600 W RMS

The Audison Forza AF C4D is a compact 4-channel amplifier that efficiently provides clean power to your system. Its straight-wire architecture foregoes internal analog preamplifier functions, making it ideal if you already use an external DSP. With an extended bandwidth up to 40 kHz, the AF C4D meets the requirements for High-Resolution Audio. A plug-and-play signal input cable for easy pairing with AF bit processor amplifiers is included, and bridgeable channel pairs give you flexibility in system setup. Available at Carhifi.shop.

Technical Highlights

• 4-channel Class-D amplifier with 84% efficiency

• Power: 90 W x 4 @ 4 Ω, 150 W x 4 @ 2 Ω, bridged 300 W x 2 @ 4 Ω
• High-Resolution capable: bandwidth up to 40 kHz
• Straight-wire design: without internal crossovers, for operation with external processors
• Plug-and-play signal input cable for AF bit processor amplifiers included
• High-level and low-level inputs, switchable ART Auto Turn-On
• Compact design: 200 x 134 x 47 mm

Installation & Compatibility

The AF C4D was designed as a companion amplifier to AF bit processor amplifiers and works equally well with standalone DSPs such as the bit One HD Virtuoso. You can bridge channel pairs if you want to actively drive a front system and additionally power a 4-Ω subwoofer, for example. Thanks to high and low-level inputs, the amplifier can be connected to both factory radios and aftermarket head units. Since there are no internal crossovers, filters and time correction are handled directly by the DSP – ensuring the signal remains clean and controlled.
