Rega Aos MC Phono Preamp

The Rega Aos MC Phono Preamp is a dedicated moving coil phono stage engineered with rear-panel RCA inputs and adjustable impedance architecture to integrate directly with a wide variety of cartridges. Drawing its core electronic layout from reference-tier engineering, the unit amplifies low-level cartridge signals with exceptional accuracy, letting listeners experience the full dynamic range and rhythmic drive pressed into their vinyl records.

Reference-Grade Circuit Architecture:

At the core of the Rega Aos MC is an all-analogue, two-stage Class A circuit design that operates without digital processing. The input stage uses parallel-connected, low-noise field-effect transistors configured to prevent bias current from entering the delicate cartridge coil. This protects the magnetic balance of the pickup while driving the passive high-frequency equalization stage with absolute clarity and lifelike detail.

Tailored Cartridge Versatility:

Because every moving coil cartridge demands specific electrical matching, the Rega Aos MC features rear-panel dip switches for quick fine-tuning. Listeners can adjust resistive loading across four settings, select between two capacitive load options, and apply a 6 dB gain boost for extra-low-output pickups. This adaptability ensures tonal balance, crisp high frequencies, and optimal volume matching across diverse audio collections.

Interference-Free Aluminum Enclosure:

Housed in a custom half-width shielded aluminum casework, the Rega Aos MC effectively blocks external electromagnetic noise and radio frequency interference from contaminating fragile musical signals. Internal self-adjusting servo circuitry continuously compensates for temperature fluctuations during extended listening, while an automatic standby function reduces power draw when the system rests between album sides.
