DSP Amplifier | 1200 W | 7 CH DSP + 1 x 1200 W @ 1 ohm | D-class

The Audison Forza AF M1.7 bit combines a powerful Class-D amplifier with cutting-edge DSP technology. This amplifier delivers 600W RMS at 4Ω, 1000W at 2Ω, and 1200W at 1Ω—matching the proven Forza AF M1D—but adds a powerful 24-bit, 96kHz DSP. The bit Drive software for the AF M1.7 bit includes specific algorithms for optimizing in-car subwoofer performance. The DSP provides equalization, crossover, time delay management, level adjustments, and dynamic loudness. The AF M1.7 bit also features the exclusive “Bass-Magnifier” function, which maximizes low-frequency output in the cabin for an immersive listening experience and realistic dynamic response. It supports 8 input channels and up to 12 using the optional F4IN card with flexible routing and mixing capabilities via the bit Drive software. It includes the Universal Speaker Simulator (USS) circuit for perfect integration with OEM audio systems. The AF M1.7 bit is compatible with the high-resolution Bluetooth receiver B-CON and its B-CON go app for remote control from a smartphone. Compatibility extends to the new DRC MP CAN and DRC AC remote controllers. The AF M1.7 bit is ideal for car audio enthusiasts seeking exceptional sound quality and advanced control features.
