It features a digital frequency display, seven station presets, and automatic AFC and muting for stable, low-effort listening. Bar graph indicators show both signal strength and centre tuning, while a stereo indicator confirms stereo reception. Under the hood it uses traditional analogue tuner circuitry — RF transformer, balanced mixer, ceramic IF filter, and a phase-locked stereo decoder — with a microprocessor handling only the display and preset functions. Signal-to-noise ratio is rated at 76dB mono and 70dB stereo, with distortion of just 0.15% at 1kHz. Output is via DIN line-level connection, upgradeable to phono\/RCA. Mains voltage is switchable between 100–127V and 200–250V.\u003c\/p\u003e\n\n\u003cp\u003eA great opportunity to own a Quad FM4 at this price point.\u003c\/p\u003e","brand":"Quad","offers":[{"title":"Default Title","offer_id":53961588736337,"sku":null,"price":99.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/6913\/0833\/files\/78565f79-3fdc-4f67-b49c-ed137e610076.jpg?v=1780656523","url":"https:\/\/www.audiotrader.co.uk\/products\/quad-fm4-hi-fi-tuner-excellent-w-original-box","provider":"Audio Trader","version":"1.0","type":"link"}
