Description
Cambridge Audio Alva Duo : Phono Preamp
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.
