Alva Duo Moving Coil & Moving Magnet Phono Preamp
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
Overview
“Rarely does Cambridge fire too wide of the mark, but the Duo hits right at the center of the target.”– ‘What Hi-Fi’ – 5 Star review.
Quality headphone amp
If you want to hear every nuance and background detail of your favorite music then listening with headphones takes some beating. Use the dedicated headphone amp built into the Alva Duo and you’ll experience a whole new level of detail. With precise volume control, you’ll get exactly the right level – whatever your choice of headphones.
Perfect for amps without a phono preamp built-in
Many amplifiers no longer come with a built-in phono preamp, which is fine if you don’t use vinyl but not so good if you want to spin some records. The Cambridge Audio Alva Duo is a dedicated phono preamp, meaning you can add a record deck to just about any amp or system with a standard AUX input. This means your choice of stereo amp or a receiver is greatly expanded and, of course, you can retain the Alva Duo phono preamp if you upgrade your main amp.
Perfect for amps with a phono preamp built-in!
Even if your main amplifier already has a phono preamp built-in, the chances are that the one inside the Alva Duo is considerably better. Using a dedicated, switch-mode power supply, the Duo is far quieter than most built-in phono preamps. The revised circuit board layout with surface-mount components further reduces noise and distortion. Factor in the shielded casing and you’ll simply hear more music and less background noise.
MC cartridge compatibility
One of the biggest advances over its little brother, the Solo, is the ability to amplify MC (Moving Coil) cartridges. These have an even lower output than MM (Moving Magnet) cartridges and require dedicated amplification. Once correctly amplified, the sound quality is stunning with a smoother yet more detailed sound. If you’re serious about vinyl then fitting a good quality MC cartridge is an upgrade that you won’t regret.
Subsonic filter
Not all records are pressed the same – due to the poor quality of vinyl used, some sound considerably noisier than others. Wear and tear can play a role in reducing quality, too. With its subsonic filter, the Alva Duo filters out low-frequency rumble; reducing distortion and protecting your speakers’ woofers from excessive wear.
Give your system a double whammy upgrade, with the Cambridge Audio Alva Duo.
Vinyl as it's Supposed to Sound
Whether you’re dusting off your record collection or embracing analogue through the vinyl revival, there’s a unique experience to be had from the moment you drop the needle on your favourite album. To preserve the unique warmth of the vinyl sound, the Duo phono preamplifier has been carefully designed with a state-of-the-art switch mode power supply and a new surface mounted circuit board layout to reduce unwanted noise.
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.
