The Audison Forza F4IN accessory is an analog input extension board, compatible with the new line of Audison AF bit amplifiers with integrated Dsp.
The card fits the dedicated external slot of the AF bit amplifier and adds four analog high-voltage input channels to the AF bit native eight, thus reaching a total of twelve high-level (SPK IN) inputs.
With respect to the sensitivity range of the AF bit native eight SPK IN inputs (2.2 ÷ 22 VRMS), the F4IN features 3.2 ÷ 32 VRMS to allow a perfect integration in advanced OEM systems with higher voltages.
