For\ninstallations where the audio and video are separated\nbefore video processing, the Meridian 251 has adjustable\n80ms audio delay to realign the audio with the video.\u003cbr\u003e\u003cbr\u003e\nFIFO RECLOCKING\u003cbr\u003e\nClock variations, known as jitter, are one the main causes\nof unpleasant “glare” in digital audio systems. The\nMeridian 251 solves this problem with our proprietary\njitter reduction technique using a FIFO (first-in firstout)\nbuffer that allows an independent output clock to\ndeliver clock performance that does not rely upon on the\nincoming signal quality.\u003cbr\u003e\u003cbr\u003e\nDSP UPSAMPLING AND APODISING FILTERS\u003cbr\u003e\nAlmost all audio has been digitally processed, even if it\narrives at the Meridian 251 in analogue form. Upsampling\nallows the Meridian 251’s DACs to run at a higher sample\nrate and achieve their full potential. Upsampling also\nprovides the opportunity to apply apodising correction to\nameliorate time-domain errors that have been introduced\nto the signal by the ADCs or other upstream processing.\u003cbr\u003e\u003cbr\u003e\nMQA\u003cbr\u003e\nMaster Quality Authenticated (MQA) is a revolutionary\nend-to-end technology that delivers master quality audio\nin a file that’s small enough to stream or download.\u003cbr\u003e\u003cbr\u003e\n\nTECHNICAL SPECIFICATION:-\u003cbr\u003e\nAUDIO OUTPUTS\u003cbr\u003e \n• Speaker outputs on Phoenix connectors \u003cbr\u003e\n• 24-12 AWG Compatible\u003cbr\u003e\n• 2 x 100w into 4Ω nominal load (2 x 65w into 8Ω) • 40kHz Bandwidth\u003cbr\u003e\n• 2-channel line-level analogue output on RCA phono connectors\u003cbr\u003e\n• Twin 192kHz 24-bit DACs\u003cbr\u003e\u003cbr\u003e\nAUDIO INPUTS \u003cbr\u003e\n• One 2-channel digital coaxial S\/PDIF input. 44.1kHz to 192kHz sampling and up to 24-bit\u003cbr\u003e\n• One 2-channel Meridian SpeakerLink input. 44.1kHz to 192kHz sampling and up to 24-bit\u003cbr\u003e\n• One 2-channel digital optical TOSLINK input. 44.1kHz to 96kHz sampling and up to 24-bit\u003cbr\u003e\n• One 2-channel analogue input on RCA phono connectors\u003cbr\u003e\n• One network input (Ethernet) for connection to Meridian Sooloos or third party control interface\u003cbr\u003e\u003cbr\u003e\nCONTROL SIGNALS \u003cbr\u003e\n• IP Control\u003cbr\u003e\n• IR on 3.5mm jack\u003cbr\u003e\n• Meridian Comms\u003cbr\u003e\u003cbr\u003e\nDISPLAY\u003cbr\u003e \n• LEDs to indicate source selection and MQA status\u003cbr\u003e\u003cbr\u003e\nPOWER\u003cbr\u003e \n• Advanced linear power supply: 110–120V ac 50–60Hz | 220-240V ac 50-60Hz\u003cbr\u003e\u003cbr\u003e\nDIMENSIONS\u003cbr\u003e \n• HEIGHT: 42mm (without feet) \u003cbr\u003e\n• WIDTH: 203mm\u003cbr\u003e\n• DEPTH: 221mm (226mm inc. connectors)\u003cbr\u003e \n• WEIGHT: 2.5kg\u003cbr\u003e\u003cbr\u003e\nRACK-MOUNTING \u003cbr\u003e\n• 1U tall rack kit available with space for two units\u003cbr\u003e\n• Optional VESA mount brackets","brand":"Meridian","offers":[{"title":"Default Title","offer_id":57413518983500,"sku":"MERIDIAN251","price":2083.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Meridian-251.jpg?v=1777544321","url":"https:\/\/www.stoneaudio.co.uk\/products\/meridian-251-powered-zone-controller","provider":"Stone Audio","version":"1.0","type":"link"}
