Audison Forza AF C4.10 bit - 4-Channel DSP Amplifier with 24 Bit/96 kHz and up to 4x150 W
The Audison Forza AF C4.10 bit is a compact 4-channel DSP amplifier that combines clean power with modern D-Class technology. You get 4 x 90 W at 4 Ω or 4 x 150 W at 2 Ω, optionally bridged to 2 x 300 W at 4 Ω. The native DSP operates at 24 Bit/96 kHz, extends the audio band up to 40 kHz, and thus meets Hi-Res requirements. Thanks to high switching frequencies, steep filters, and precise component tolerances, the system can be finely tuned. In addition, the amplifier supports the Audison B-Con Absolute-Volume function, ensuring maximum bit depth is maintained during wireless playback.

Installation & Compatibility
The AF C4.10 bit fits into many vehicles due to its compact dimensions and integrates cleanly into OEM systems thanks to 8 high/low-level inputs and optical S/PDIF. The automatic turn-on function (ART/AST) simplifies retrofitting. For setups requiring more power, you can bridge channel pairs; note 4 Ω in bridged mode and a minimum of 2 Ω in stereo mode. The six preamplifier outputs and the expansion slot offer room for future upgrades.
