Mosconi FSA - Front Stage Adjuster

The Mosconi FSA (Front Stage Adjuster) is a plug-in accessory card for compatible Mosconi amplifiers that uses phase adjustment at defined frequencies to electronically correct soundstage positioning and imaging — without requiring physical speaker relocation or complex DSP tuning.

In most car audio installations, the listening position is asymmetric relative to the speakers: the driver is closer to the left speaker than the right, and tweeters are often mounted low in the doors rather than at ear level. The FSA addresses this by applying carefully calculated phase shifts to the drive-side channel, effectively shifting the perceived soundstage to centre without time alignment delays. It's built entirely from high-performance analogue components to preserve signal quality.

Specifications

• Dimensions: 41 x 30 x 17 mm

Ideal For

Any Mosconi amplifier-equipped installation where soundstage centralisation is needed without a DSP. A cost-effective solution for improving imaging in installations where the driver sits closer to one speaker than the other.
