Rega AOS MC Phono Stage Launches as a More Affordable, Aura-Derived Moving Coil Design
Rega AOS MC phono stage borrows heavily from reference Aura MC, delivering a two-stage, pure-analogue moving-coil design without any digital control circuitry.
Circuit uses parallel low-noise FET compound pairs drawing zero cartridge bias current, preserving MC magnetic geometry, with a self-adjusting servo compensating ambient and temperature drift.
Rear-panel DIP switches enable resistance loading from 70Ω–400Ω, capacitance 1000–4300pF, plus a 6dB gain toggle for low-output MC cartridges.
