Audia Flight FLS MM/MC Phono Board

The Audia Flight FLS MM/MC Phono Board is a dedicated phono stage designed for clean integration into the rear bay of an FLS series component. It adds two phono inputs, one Moving Magnet (40 dB gain) and one Moving Coil (60 dB gain), with dip-switch impedance loading on both channels. The MC stage offers loading from 20 Ω to 1500 Ω across the front-panel switch banks, and custom resistor sockets allow values outside the table.

Installation Slot (A Bay / B Bay)

Every FLS series component (FLS 1, FLS 9, FLS 10) has two removable rear-panel bays where optional boards install: A bay (top) and B bay (bottom). Each FLS optional board has a fixed bay assignment based on its panel layout, and up to two boards can be installed at once, one per bay.

FLS optional board bay assignments:

• FLS DAC Board: A bay only
• FLS XLR Expansion Board: A bay only
• FLS MM/MC Phono Board: B bay only
• FLS RCA Expansion Board: B bay only

Boards that share a bay are mutually exclusive: DAC and XLR cannot both be installed (both A bay), and Phono and RCA cannot both be installed (both B bay). Any A-bay board pairs cleanly with any B-bay board.

This phono board installs in B bay. Common pairings: Phono + DAC (A+B) and Phono + XLR (A+B). Phono and RCA cannot coexist because both occupy B bay.
