Audison Forza AF C4.10 bit is a 4-Channel DSP Amplifier with Audison D-Class (ADT) technology and 600 W RMS total power. The continuous output power is 90 W x 4 at 4 Ω, 150 W x 4 at 2 Ω, and bridged 300 W x 2 at 4 Ω with a minimum of 2 Ω. The integrated DSP operates at 24 Bit/96 kHz, extends the audio band up to 40 kHz, and offers a bandwidth of 10 Hz to 42 kHz at −1.5 dB. Specifications include 0.03% THD @ 1 kHz (4 Ω, 70% rated power), a damping factor of 95, and S/N ratios of 98 dBA (Master input) and 105 dB (optical input). The efficiency at rated power is 81%, and channel pairs are bridgeable. The input section includes 8 high/low-level inputs, Pre-In 0.6–6 VRMS (15 kΩ), speaker inputs 2.2–22 VRMS (5 Ω), as well as an optical S/PDIF input up to 192 kHz/24 Bit and optionally optical/coaxial via F2O card. Outputs include 6 preamplifier outputs, expandable by 4 optional, controlled via the DSP. Features include support for the Audison B-Con Absolute-Volume function, the bit Drive software platform, electrical signal analysis per input channel, acoustic analysis with USB microphone, and RTA.
