Description

AF M1.7 bitDSP 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.

Technologies

Next-generation bit Drive software platform – developed for this family of products – simplifies every control and function.

Native DSP working at 24 bit/96 kHz and an extended audio band up to 40 kHz.

The acoustic analysis integrates the response graph into the equalizer display ensuring efficient tuning and great sound, compatible with any 24-bit USB microphone.

The electrical analysis integrates the response graph into the input equalizer display, ensuring efficient tuning.

Electrical Signal Analysis ensures proper integration and correction for each input channel.

Enjoy the improved audio performance of the latest generation Audison D-Class technology.

Forza amplifiers have two independent power supplies: the audio amplifier power supply is loosely regulated, which allows superior dynamic performance. The DSP power supply is stiffly regulated, which maintains DSP microprocessor operation even during lower-voltage transient states (i.e., start/stop operation).

Quick I/O Configuration speeds up system definition and signal routing.

When connected with Audison B-CON hi-res Bluetooth receiver, this feature manages the Master Volume of the Forza amp thus ensuring full dynamic range signal at the input.
