The Super-Value Cambridge Audio Duo MM/MC Phono Preamplifier Also Includes Headphone Amplifier with Volume Control.
Enjoy every last detail from your vinyl collection with our highest quality moving magnet and moving coil phono stage, the Duo Phono Preamplifier.
The Alva Duo was designed around exceptional components that deliver the warm and detailed sound that’s synonymous with vinyl, all without distorting the signal from the cartridge. 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.
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.
