Cambridge Audio Alva Duo Phono Pre-amp - Cambridge Audio

British attention to detail shines throughout this Cambridge Audio Alva Duo MM/MC phono pre-amp
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.

Key Features

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 favorite album. To preserve the unique warmth of the vinyl sound, the Alva 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 output of a turntable, not all amplifiers will let you connect directly to a record player. The phono pre-amp boosts this signal so a power amplifier can work with it. 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.

Vinyl, for Your Ears Only
Enjoy the warmth of vinyl privately thanks to Duo’s integrated headphone output. Uniquely, we integrated a 1/4" 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.

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.

Headphone amplifier
The Cambridge Duo has a built-in headphone amplifier with a full-size 1/4" jack so you can crank up your favorite tunes without waking up the whole house.

The Cambridge Duo is a perfect solution for private record listening. You can plug your headphones into the jack on the front, and the built-in headphone amp does a fantastic job of revealing the warm analog sound that vinyl is so rightly known for. It's compatible with moving magnet and moving coil cartridges, so you can upgrade your turntable or cartridge and keep using this same pre-amp. And of course, if you ever need to listen out loud, you can connect a pair of powered speakers and go for it. The versatility of the Cambridge Duo makes it a go-to component in just about any scenario.
