The Cambridge Audio Alva Duo is a premium moving-magnet and moving-coil phono preamplifier designed to reveal greater warmth, clarity, and detail from your vinyl collection. Its low-noise switch-mode power supply and surface-mounted circuit design minimize unwanted hum and preserve the delicate signal produced by your turntable. An integrated headphone amplifier with a full-size 6.35mm output enables private vinyl listening without switching on your main amplifier. A subsonic filter helps reduce low-frequency rumble from imperfect records, while the balance control compensates for cartridge channel imbalance. Automatic power-down and low standby consumption make the Alva Duo an efficient, versatile upgrade for MM and MC turntable systems.
