Audison Force AF M12.14 bit

Audison AF M12.14 bit - 12-Channel DSP Amplifier with Hi-Res Audio

The Audison AF M12.14 bit is a compact 12-channel amplifier with integrated DSP, providing precise system control and high output power in one device. 60 W x 12 at 4 Ω, 90 W x 12 at 2 Ω, and 180 W x 6 bridged at 4 Ω offer flexible configurations from fully active setups to powerful OEM upgrades. The DSP operates at 24 bit/96 kHz, extends the audio band up to 40 kHz, and meets Hi-Res requirements. The support for the Absolute Volume function of the Audison B-CON ensures maximum resolution, even wirelessly.
