The Cambridge Audio Alva Duo MC Phono Amplifier delivers a true and uncolored sound reproduction from your vinyl, ensuring an authentic listening experience. Designed for both moving magnet and moving coil cartridges, it optimally preserves the details that vinyl records capture.
At the core of the Cambridge Audio Alva Duo MC Phono Amplifier is its precision circuit design, which focuses on pure analog signal transmission to enhance sound fidelity. The unit features a switch-mode power supply that operates outside of audible frequencies, effectively suppressing hum and noise that could interfere with playback. By implementing a dedicated gain structure for both moving magnet (MM) and moving coil (MC) cartridges, the Alva Duo achieves maximum signal integrity and dynamic range, allowing it to faithfully reproduce the subtle nuances found in vinyl records. The inclusion of a subsonic filter helps eliminate low-frequency artifacts that can arise from worn records, further refining the listening experience. Complementing these features is a built-in headphone amplifier, providing a direct and personal listening solution without the need to engage a larger hi-fi system, while the unit’s eco-friendly design minimizes power consumption, emphasizing efficiency and sustainability in acoustic playback.
Key Features
- Dedicated MM & MC phono preamp: Utilizes separate signal paths for moving magnet and moving coil cartridges to optimize gain and response.
- Switch-mode power supply: Functions at frequencies beyond human hearing to minimize interference and audio hum.
- Surface-mounted circuit board: Reduces the signal path length and enhances clarity by maintaining pure signal integrity.
- 6.35mm headphone output: Allows for personal listening with full fidelity, eliminating the need for an external amplifier.
- Auto power-down: Conserves energy by switching off the unit after 20 minutes of inactivity.
- Subsonic filter: Targets and removes unwanted low-frequency noise from records, providing clearer audio playback.
- Eco-friendly listening: Designed for low standby power consumption and universal voltage compatibility, minimizing environmental impact.
