Cambridge Audio Duo 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 the Duo has been designed 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.

Enjoy the warmth of vinyl privately thanks to Duo’s integrated headphone output.
With a 6.35mm headphone jack integrated directly into the phono stage, 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.
