It raises the cartridge's tiny signal to line level, 300 mV nominal, with a gain of 39 dB for MM and 60 dB for MC.\u003c\/p\u003e\u003cp\u003eInput impedance is 47 kohms for MM and 100 ohms for MC, with an input capacitance of 100 pF; the RIAA curve is followed within ±0.3 dB from 30 Hz to 20 kHz.\u003c\/p\u003e\u003ch2\u003eBuilt-in headphone amplifier\u003c\/h2\u003e\u003cp\u003eThe Alva Duo has a headphone amplifier with a 6.35 mm output on the front panel: it allows records to be enjoyed privately, even late at night, without switching on the rest of the system. Just connect the turntable and the headphones.\u003c\/p\u003e\u003cp\u003eThe subsonic filter removes the very low frequencies produced by worn records, for a cleaner sound.\u003c\/p\u003e\u003ch2\u003eA low-noise design\u003c\/h2\u003e\u003cp\u003eThe switch-mode power supply operates outside the audible frequencies, so it introduces neither hum nor interference, and the surface-mounted circuit keeps the signal as clean as possible. The stated signal-to-noise ratio exceeds 90 dB with MM and 70 dB with MC; THD+N at 1 kHz is below 0.0025% (MM) and 0.20% (MC), with an overload margin above 30 dB.\u003c\/p\u003e\u003cp\u003eAfter 20 minutes of inactivity the unit switches itself off; in standby it draws less than 0.5 W, at most 10 W in use, and it accepts mains voltages worldwide.\u003c\/p\u003e\u003ch2\u003eDimensions and accessories\u003c\/h2\u003e\u003cp\u003eThe Alva Duo is grey, measures 48 x 215 x 159 mm (height, width, depth) and weighs 0.95 kg: at 215 mm wide it takes up half the space of a traditional hi-fi component.\u003c\/p\u003e\u003cp\u003eThe box contains the mains lead, the user manual and the safety guide.\u003c\/p\u003e","brand":"Cambridge Audio","offers":[{"title":"Default Title","offer_id":42408982806717,"sku":"CAM-C10935","price":373.43,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5278\/7645\/files\/cambridge-audio-alva-duo-igbjg.jpg?v=1791448781","url":"https:\/\/videosell.eu\/products\/cambridge-audio-alva-duo","provider":"Videosell store","version":"1.0","type":"link"}
