Its frequency response extends from 5Hz to 45kHz, and signal quality is exceptionally clean with a 100dB signal-to-noise ratio and just 0.005% total harmonic distortion across the full audio band. A standout feature is the built-in spectrum analyzer display, which offers five display modes - bars, peak-hold, dot, hustler, and Aurora - alongside six memory presets for storing and recalling EQ curves. With 22kΩ input impedance and 1V nominal sensitivity, it integrates neatly into a standard line-level hi-fi chain.\u003c\/p\u003e\n\n\u003cp\u003eA great opportunity to own a Technics SH-E51 at this price point.\u003c\/p\u003e","brand":"Technics","offers":[{"title":"Default Title","offer_id":55193406341457,"sku":null,"price":145.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/6913\/0833\/files\/0da08de1-082f-4fa9-8710-6d6a28fd4637.jpg?v=1791284250","url":"https:\/\/www.audiotrader.co.uk\/products\/technics-sh-e51-equaliser-black-very-good-w-original-box-manuals","provider":"Audio Trader","version":"1.0","type":"link"}
