Mosconi G-FSA - Front Stage Adjuster
Taxes & Shipping Included
The Mosconi G-FSA is the G-card format version of Mosconi's Front Stage Adjuster — a compact plug-in card that uses analogue phase adjustment to electronically improve soundstage positioning and imaging in car audio installations equipped with compatible Mosconi amplifiers.
The G-card slot system, found across Mosconi's D2, AS, ZERO, A CLASS, and ONE amplifier lines, allows accessories like the G-FSA to be installed directly inside the amplifier for a clean, integrated result. No external wiring, no additional boxes — just insert the card and the FSA functionality is built in. Like the standard FSA, it uses only high-quality analogue components to maintain signal integrity throughout.

When To Choose G-FSA vs FSA
If your Mosconi amplifier has a G-card slot (most current models do), choose the G-FSA for a cleaner, fully integrated installation. The standard FSA is for older Mosconi amplifiers without the G-card slot system.
