It takes the low level signal from a moving magnet cartridge and brings it up to line level, so records can be played with full detail and warmth.\u003c\/p\u003e\n\u003cp\u003eThe Alva Solo uses a switch mode power supply and a surface mounted circuit board to keep hum and background noise low. This helps music sound clean and clear. For records that are worn or warped, a subsonic filter cuts out low frequency rumbles. An adjustable balance control is included to fix channel imbalances from the cartridge. These features help keep the soundstage balanced in a stereo system.\u003c\/p\u003e\n\u003cp\u003eTechnically, the preamplifier provides thirty nine decibels of gain at one kilohertz, yielding a nominal output of three hundred millivolts from a three point thirty five millivolt input sensitivity rating. It features aThe preamplifier delivers thirty nine decibels of gain at one kilohertz, with a nominal output of three hundred millivolts from a three point thirty five millivolt input. Input impedance is forty seven kilohms and input capacitance is one hundred picofarads. The RIAA equalization curve stays within plus or minus zero point sixty five decibels from thirty Hertz to twenty kilohertz. Signal to noise ratio is over ninety decibels, and total harmonic distortion plus noise is kept below zero point zero zero two five percent. For efficiency, the unit draws less than half a Watt in standby and powers down after twenty minutes without use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Cambridge Audio","offers":[{"title":"Grey","offer_id":47254008627284,"sku":"CAM:SOLO-LG","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0572\/3281\/8260\/files\/1_791645f1-a3b5-44ae-ac14-c16d17ff7fb5.png?v=1782387353","url":"https:\/\/www.audioadvice.com\/products\/cambridge-audio-alva-solo-moving-magnet-phono-preamplifier","provider":"Audio Advice","version":"1.0","type":"link"}
