Six line-level analog and phono inputs travel through the Mark Levinson proprietary Pure Path discrete, direct-coupled, fully balanced, dual-monaural signal path for breathtaking purity and performance. With precision control including a discrete, balanced R-2R Ladder volume control, class-A Pure Phono stage, and class-A Main Drive Headphone output, the № 523 preamplifier delivers an uncompromising performance regardless of analog source. Housed in a 6000-series aluminum chassis, like all Mark Levinson equipment, the № 523 is designed and handcrafted in the USA.\u003cbr\u003e\u003cbr\u003e\n\nThe № 523 offers five line-level analog inputs: two balanced (XLR), three single-ended (RCA), in addition to the Pure Phono (RCA with grounding pin) input. The preamplifier delivers its signal to balanced (XLR) and single-ended (RCA) stereo outputs, as well as a 1\/4-inch (6.3mm) Main Drive Headphone output integrated into the front panel metalwork – a first for Mark Levinson.\u003cbr\u003e\u003cbr\u003e\n\nThe Main Drive Headphone amplifier circuit drives up to 32-ohm headphones in class A by employing the main output circuit rather than a secondary signal path: a perfect example of reducing clutter in the circuit design.\u003cbr\u003e\u003cbr\u003e\n\nA selectable fourth-order, 80 Hz high-pass filter enables seamless integration of a single or dual subwoofers for full-range performance with a wide range of loudspeaker setups.\u003cbr\u003e\u003cbr\u003e\n\nSystem-integration connectivity includes Ethernet\/IP control, RS-232, USB for monitoring and configuration via web page, plus 12V triggers and an IR input. An included machined metal remote delivers the robust feel and precise control befitting of a component of the preamplifier’s caliber.\u003cbr\u003e\u003cbr\u003e\n\nDesigned and Handcrafted in the USA\u003cbr\u003e\u003cbr\u003e\n\nLike all Mark Levinson equipment, the № 523 is proudly designed and handcrafted in the USA. A dedicated Engineering Center of Excellence in Shelton, CT houses Mark Levinson engineering and product development, just a state away from small-batch production at Mack Technologies in Westford, MA by a team of craftsmen who bring all Mark Levinson equipment to life.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:-\u003cbr\u003e\u003cbr\u003e\n\nPower consumption:\n0.4W Green Standby, 5W Power Save, 67W Normal Standby, 70W On, idle\u003cbr\u003e\n\nDimensions:\u003cbr\u003e\nHeight (with feet): 3.75” (10.2cm)\u003cbr\u003e\nHeight (without feet): 3.25” (8.9cm)\u003cbr\u003e\nWidth: 17.25” (43.8cm)\u003cbr\u003e\nDepth: 18” (45.7cm)\u003cbr\u003e\u003cbr\u003e\n\nWeight:\u003cbr\u003e\nNet weight: 39 lbs (17.7kg)\u003cbr\u003e\nShipping weight: 58 lbs (26.3kg)\n\n\n\n\n\n\n","brand":"Mark Levinson","offers":[{"title":"Default Title","offer_id":57413108629836,"sku":"MARKLEVINSONNO523","price":13333.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Mark-Levinson-523.jpg?v=1777539467","url":"https:\/\/www.stoneaudio.co.uk\/products\/mark-levinson-no-523-dual-monaural-pre-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
