Audison Accessories F4IN ANALOG INPUT EXTENSION CARD

F4IN Accessories | Forza Analog Input Extension Board | For Audison AF Bit Amplifiers with Integrated DSP

The Audison F4IN is a dedicated analog input extension module designed to expand the input capabilities of the Audison AF bit amplifier series. Installed via the amplifier’s external input slot, the F4IN board adds four additional high-voltage analog input channels to the amplifier’s existing eight, bringing the total to twelve high-level speaker inputs (SPK IN).

Unlike the native AF bit inputs, which support 2.2–22 VRMS, the F4IN is engineered for 3.2–32 VRMS compatibility, making it the ideal solution for integrating into advanced OEM audio systems with higher signal voltage. This allows perfect signal management when tapping into factory systems from premium vehicle brands.

F4IN is particularly useful for upgrading vehicles equipped with OEM subwoofer outputs in systems like:

• Audi A5/S5 2015 with Bang & Olufsen
• Audi Q5 and A6 4G with B&O or Bose
• BMW models with Harman/Kardon
• Porsche Cayenne 2018 with Bose
• Skoda Octavia 2022 with Canton
• Volvo FH12 with DVC OEM subwoofer (8+8 Ohm)

With plug-and-play installation, the F4IN provides seamless integration, extended input capacity, and uncompromised signal quality for high-end factory system upgrades.
