Cambridge Audio ALVA Duo Moving Coil & Moving Magnet Phono Preamplifier
Enhance your vinyl listening experience with the Cambridge Audio ALVA Duo Phono Preamplifier. Designed for both moving magnet and moving coil cartridges, this high-quality phono stage features an integrated headphone amp, allowing you to squeeze every inch of detail from your record collection. Whether you're rediscovering old favorites or exploring new records, the ALVA Duo ensures that you hear your vinyl as it’s supposed to sound.
Vinyl as it's Supposed to Sound
The ALVA Duo Phono Preamplifier is meticulously engineered to preserve the unique warmth and depth of vinyl sound. Featuring a state-of-the-art switch mode power supply and a new surface-mounted circuit board layout, the Duo reduces unwanted noise and interference. From the moment you drop the needle on your favorite album, you'll experience music with unparalleled clarity and detail.
Why Choose a Dedicated Phono Preamplifier?
Turntables produce low-level signals that many hi-fi amplifiers cannot handle directly. A dedicated phono preamplifier like the ALVA Duo boosts this signal to a level that power amplifiers can work with, without introducing noise. The Duo is designed around exceptional components to deliver the warm, detailed sound synonymous with vinyl, without distorting the signal from your moving magnet or moving coil cartridge turntable.
Vinyl. Just for You
With the ALVA Duo’s integrated headphone output, you can enjoy the warmth of vinyl privately. This unique feature includes a 6.35mm headphone jack directly in the phono stage, so you can listen to your records even when you can't play them out loud. This design also means you don't need to turn on your amplifier just to power your headphones, making for a more eco-friendly listening experience.
Attention to Detail
The ALVA Duo includes a subsonic filter to eliminate low-frequency rumbles caused by vinyl imperfections. The balance control handles potential cartridge imbalances in your record player, ensuring a detailed listening experience with accurate soundstage. These features combine to deliver pristine audio quality, even from worn records in your collection.
Eco Friendly
The ALVA Duo Phono Preamplifier is designed with sustainability in mind. It consumes less than half a watt in standby mode and features an auto power down function after 20 minutes of inactivity. This eco-friendly design is complemented by worldwide voltage compatibility, ensuring the Duo can be used anywhere in the world with minimal environmental impact.
