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.

iDatalink Maestro AR native support for a total integration with OEM infotainment.

Equipped with eight analog inputs, to support total connectivity even with the most complex OEM systems.

Automatically sums and reverses OEM equalization.

Input delay compensation of time-delayed factory outputs prior to signal summing.

Allows left and right inputs to match in phase before tuning, even if OEM phase processing has been used.

Universal Speaker Simulator technology on high-level inputs for maximum compatibility with any type of Head-Unit OEM Source.
