Engineered with an ultra-wide frequency bandwidth (1Hz to 300kHz) and a compact, mechanically rigid chassis, the HQA provides a pure, transparent soundstage free from micro-dynamics veiling or electronic distortion.\u003c\/p\u003e\n\n\u003cp\u003eInside, the amplifier features high-current 16A audio MOSFET power transistors, a massive 300VA low-noise toroidal transformer, and a generous 44,000 µF Vishay capacitive filter array. Built for long-term reliability and ease of serviceability, the chassis incorporates a 6mm PMMA non-conductive rear panel to eliminate electrical crosstalk, machined Delrin decoupling feet, and a clean PCB layout designed to be easily serviced for decades to come.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp; SYSTEM HIGHLIGHTS\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eHigh-Current MOSFET Output Stage:\u003c\/strong\u003e Equipped with special audio-grade MOSFET transistors rated at 16A capacity to deliver dynamic, effortless power into low-impedance speaker loads.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eUltra-Wideband Transparency:\u003c\/strong\u003e Extremely wide frequency bandwidth (1Hz to 300kHz) preserves low-level reverberation details, micro-transients, and precise spatial soundstaging.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eRobust Linear Power Supply:\u003c\/strong\u003e Features a low-noise 300VA toroidal transformer, dedicated driver-stage shunt regulation, and 44,000 µF of 105°C Vishay filtering capacitors.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eResonance \u0026amp; Electrical Isolation:\u003c\/strong\u003e Built on a mechanically welded chassis with a 6mm non-conductive PMMA rear panel and 3 machined Delrin feet to eliminate micro-vibrations and connector crosstalk.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eLoudspeaker \u0026amp; Circuit Protection:\u003c\/strong\u003e Includes integrated short-circuit and thermal overload protection to safeguard both the amplifier and connected speakers.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDesigned for Decades of Serviceability:\u003c\/strong\u003e Features solid aluminum control knobs and a clean, widely spaced printed circuit board layout to ensure straightforward maintenance and repairability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\n\n\u003ctable style=\"width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Category\u003c\/td\u003e\n      \u003ctd\u003eStereo Integrated Power Amplifier\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePower Output\u003c\/td\u003e\n      \u003ctd\u003e2 x 80 Watts RMS\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFrequency Response\u003c\/td\u003e\n      \u003ctd\u003e1 Hz – 300 kHz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOutput Transistors\u003c\/td\u003e\n      \u003ctd\u003eHigh-Current Audio MOSFETs (16A capacity)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePower Transformer\u003c\/td\u003e\n      \u003ctd\u003e300 VA Low-Noise, Low-Loss Toroidal Transformer\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePower Supply Capacitance\u003c\/td\u003e\n      \u003ctd\u003e44,000 µF (105°C Vishay Capacitors)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDriver Stage Regulation\u003c\/td\u003e\n      \u003ctd\u003eIndependent Power Supply Stage with Shunt Regulation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProtection Systems\u003c\/td\u003e\n      \u003ctd\u003eIntegrated Overload \u0026amp; Short-Circuit Protection\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Panel Construction\u003c\/td\u003e\n      \u003ctd\u003e6 mm Non-Conductive PMMA Panel (Reduces Connector Coupling)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIsolation \u0026amp; Feet\u003c\/td\u003e\n      \u003ctd\u003e3 Machined Delrin Decoupling Feet\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eControl Knobs\u003c\/td\u003e\n      \u003ctd\u003eSolid Machined Aluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions \u0026amp; Chassis Type\u003c\/td\u003e\n      \u003ctd\u003eMechanically Welded Rigid Metal Chassis\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNet Weight\u003c\/td\u003e\n      \u003ctd\u003e14.0 kg (30.8 lbs)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Neodio","offers":[{"title":"Default Title","offer_id":53776200990986,"sku":"NEODIO-HQA","price":4490.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/3283\/6618\/files\/neodio-hqa-power-amplifier-43192-p_bcf6261b-1072-4452-a5f6-29d50823acb6.jpg?v=1789921710","url":"https:\/\/audioemotion.co.uk\/products\/neodio-hqa-power-amplifier","provider":"Audio Emotion Limited","version":"1.0","type":"link"}
