It boosts and equalises the low-level signal from a turntable so it can be played through any line-level input, and adds a headphone output for private listening straight from the source.\u003c\/p\u003e\n\u003ch2\u003eWhy This Model Matters\u003c\/h2\u003e\n\u003cp\u003eNot every amplifier includes a phono input, and the ones that do are often limited to moving magnet cartridges. The Alva Duo handles both moving magnet and moving coil, making it a flexible upgrade path for listeners experimenting with higher-end cartridges. A switch-mode power supply operates outside the audible band to reduce hum, while a surface-mount circuit layout and a subsonic filter keep noise and motor rumble out of the signal.\u003c\/p\u003e\n\u003cp\u003eIt reflects Cambridge Audio's \"Great British Sound\" philosophy of adding as little character as possible to the recording, and it was well received on release—What Hi-Fi called it \"a well-specified, full-bodied, dynamic performer.\" The integrated headphone amp makes it a compact, self-contained way to enjoy vinyl without a full amplifier in the chain.\u003c\/p\u003e\n\u003ch2\u003eHighlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePhono preamplifier for moving magnet and moving coil cartridges\u003c\/li\u003e\n\u003cli\u003eBuilt-in headphone amplifier\u003c\/li\u003e\n\u003cli\u003eSwitch-mode power supply to reduce hum\u003c\/li\u003e\n\u003cli\u003eSubsonic filter to eliminate motor rumble\u003c\/li\u003e\n\u003cli\u003eRCA line-level output, auto power-down, and under 0.5 W standby\u003c\/li\u003e\n\u003cli\u003ePart of Cambridge Audio's Alva vinyl range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Alva Duo is aimed at vinyl listeners whose amplifier lacks a phono input or supports only moving magnet cartridges, and at anyone who wants to listen on headphones directly from their turntable. It is a natural match for a growing system where a moving coil cartridge might be on the horizon.\u003c\/p\u003e","brand":"Cambridge Audio","offers":[{"title":"Grey","offer_id":48161218068710,"sku":null,"price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0808\/8407\/2678\/files\/duo_front.jpg?v=1786543042","url":"https:\/\/bringbackanalog.com\/products\/cambridge-audio-alva-duo","provider":"Bring Back Analog","version":"1.0","type":"link"}
