Cambridge Audio ALVA Duo Moving Coil & Moving Magnet Phono Preamp & Headphone Amplifier
Enjoy how vinyl should sound!
Enjoy the finest details of your LP collection using Cambridge Audio's latest and greatest MM/MC phono preamplifier the DUO.
The DUO is not just a successor to the CP2, the DUO also has volume control and a headphone amplifier on board and there are few phono stages with a built-in headphone amplifier.
The specifications of the mm input include a noise floor of –90 dB and the frequency range is from 30 Hz to 20 kHz. The harmonic distortion is less than 0.0025 percent.
The MC input has a noise floor of –70 dB and a distortion of approximately 0.02 percent maximum. The frequency range is also from 30 Hz to 20 kHz.
Today's amps aren't always designed with record players as a priority.
A preamp specially designed for vinyl ensures that modern amps will play your LPs in the very best quality.
The DUO phono preamplifier offers an essential improvement in sound quality over low-priced phono preamplifiers and the models sometimes fitted as standard in current equipment.
Squeeze every inch of detail from your record collection with our highest quality moving magnet and moving coil phono stage, with integrated headphone amp; the Duo Phono Preamplifier.
Why Choose a Dedicated Phono Preamplifier?
Due to the low-level signals created by a turntable, not all hi-fi amplifiers will let you connect directly to a record player. The phono preamplifier boosts this signal to something a power amplifier can work with. The challenge at this stage though is that noise can easily be added.
This is why we’ve designed the Duo around exceptional components that deliver the warm and detailed sound that’s synonymous with vinyl, all without distorting the signal from your moving magnet cartridge turntable. The switch mode power supply improves performance by switching outside of audible frequency to drastically reduce hum and new circuit board layout uses surface-mount components to reduce noise.
Vinyl. Just for You
Enjoy the warmth of vinyl privately thanks to Duo’s integrated headphone output. Uniquely, we integrated a 6.35mm headphone jack directly into the phono stage, so you can still enjoy your records when there’s no option to play out loud.
The integrated headphone output also means no need to turn on your amplifier just to power your headphones, resulting in a more eco-friendly listening experience.
Attention to Detail
If some records in your collection are a little worse for wear, the subsonic filter will help to eliminate low frequency rumbles that can be caused by imperfections within your vinyl. Combine this with the balance control for handling potential cartridge imbalances in your record player (that can cause a difference between the left and right channels) and the result is a detailed experience with accurate soundstage.
Eco Friendly
The Duo phono preamplifier is green at heart with less than half a watt standby power consumption and auto power down feature if the unit isn’t used after a 20 minute period. This in turn gives the unit the same worldwide voltage for compatibility wherever you are in the world.
