Many hi-fi amplifiers have no turntable input: the Alva Solo sits between the turntable and a line input and raises the very low-level cartridge signal to the right level, with a clean, rich and balanced sound.\u003c\/p\u003e\u003cp\u003eGain is 39 dB at 1 kHz, with a nominal output of 300 mV for a 3.35 mV input. Input impedance is 47 kohms with 100 pF capacitance, values suited to MM cartridges.\u003c\/p\u003e\u003ch2\u003eLow-noise circuit\u003c\/h2\u003e\u003cp\u003eThe switch-mode power supply reduces hum and the surface-mount circuit is laid out to keep noise down and preserve every detail on the record. The RIAA curve is followed within +\/- 0.65 dB from 30 Hz to 20 kHz.\u003c\/p\u003e\u003cp\u003eSignal-to-noise ratio exceeds 90 dB and total harmonic distortion (THD+N) at 1 kHz is below 0.0025%. Overload margin is greater than 30 dB and channel separation exceeds 85 dB at 10 kHz.\u003c\/p\u003e\u003ch2\u003eSubsonic filter and balance control\u003c\/h2\u003e\u003cp\u003eThe subsonic filter removes the very low frequencies produced by worn records, which are not part of the music. A rear-panel knob adjusts channel balance and compensates for level differences in the cartridge, for a centred soundstage.\u003c\/p\u003e\u003cp\u003eAlso on the rear are the MM input and the output on RCA sockets and the ground terminal for the turntable. The front panel carries only the power button.\u003c\/p\u003e\u003ch2\u003ePower consumption, dimensions and accessories\u003c\/h2\u003e\u003cp\u003eThe Alva Solo switches itself off after 20 minutes of inactivity and uses less than half a watt in standby; maximum consumption is 10 W and the power supply accepts mains voltages worldwide. It measures 176 x 48 x 132 mm (width, height, depth) and weighs 0.68 kg; the finish is grey.\u003c\/p\u003e\u003cp\u003eThe box contains the preamplifier, the mains lead, the user manual and the safety guide.\u003c\/p\u003e","brand":"Cambridge Audio","offers":[{"title":"Default Title","offer_id":42408986378429,"sku":"CAM-C10934","price":229.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5278\/7645\/products\/AlvaSolo-su-videosell-02.webp?v=1665657207","url":"https:\/\/videosell.it\/en\/products\/cambridge-audio-alva-solo","provider":"Videosell store","version":"1.0","type":"link"}
