Intended for professional and project studio use, it delivers the kind of clean, detailed, transformer-coupled gain that suits demanding recording applications — from tracking vocals and acoustic instruments to capturing full band sessions with consistent headroom and low noise. Its design philosophy prioritises transparency and musical warmth through analogue signal paths, making it a well-regarded tool in studios where preamp quality is taken seriously.\u003c\/p\u003e\n\n\u003cp\u003eA great opportunity to own a Focusrite ISA428 at this price point.\u003c\/p\u003e","brand":"Focusrite","offers":[{"title":"Default Title","offer_id":53785815515473,"sku":null,"price":525.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/6913\/0833\/files\/db38bc06-9554-4a29-9ce1-7ce666e2c5ed.jpg?v=1778854488","url":"https:\/\/www.audiotrader.co.uk\/products\/focusrite-isa428-pre-amplifier-very-good","provider":"Audio Trader","version":"1.0","type":"link"}
