The standing temperature is lower than that encountered in Class A series designs because it's a Class AB design.\u003cbr\u003e\u003cbr\u003e\n\nIt occupies a niche in audio systems for the person that really loves big dynamic sound like movies, orchestral pieces and of course playing music loud!\u003cbr\u003e\u003cbr\u003e\n\nThe physical construction of the SB-301 is based on the SA series designs so it has the same distinctive aesthetic as the Class A products and indeed much of the electronics topology is derived from that Class A history\u003cbr\u003e\u003cbr\u003e\n\nThis amplifier delivers all the dynamics, finesse and transparency that Plinius is renowned for. Like all Plinius products it is very reliable and will rise to the challenge of difficult operating conditions time and time again.\u003cbr\u003e\u003cbr\u003e\n\nFeatures:- \u003cbr\u003e\u003cbr\u003e\nAmplifier Configuration Selector (ACS) switch\u003cbr\u003e\n The rear panel ACS switch allows for the amplifier to be configured for Stereo RCA or XLR modes.\u003cbr\u003e\u003cbr\u003e\n \nRemote Trigger Input\u003cbr\u003e\n When connected to a preamplifier trigger output, the amplifier will switch out of Standby and be ready for use when the preamplifier is taken out of standby.\u003cbr\u003e\u003cbr\u003e\n \nGround Lift Switch\u003cbr\u003e\n This allows for the signal ground to be isolated from the main chassis earth. This can assist in resolving unwanted ground loops or hum due to duplicate ground paths in some systems.\u003cbr\u003e\u003cbr\u003e\n \nWBT and Neutrik Connectors\u003cbr\u003e\n High quality WBT RCA and Neutrik XLR input connectors are fitted along with WBT output speaker terminals to ensure a low distortion interface between your cables and the amplifier.\u003cbr\u003e\u003cbr\u003e\n \nAuricap Capacitors\u003cbr\u003e\n Audience AV supply the Auricap XO capacitors used in several key areas of the circuit.\u003cbr\u003e\u003cbr\u003e\n \nSiltech Wiring\u003cbr\u003e\n Siltech premium 'G7' silver\/gold wire provides a perfect connection between components to give clear, fast and detailed presentation of the music signal.\u003cbr\u003e\u003cbr\u003e\n \nAluminium Construction\u003cbr\u003e\n The aluminium construction provides a rigid non-magnetic housing to eliminate unwanted magnetic fields that can interfere with the sensitive audio signals.\u003cbr\u003e\u003cbr\u003e\n \nTechnical Specifications:-\u003cbr\u003e\u003cbr\u003e \n\nPOWER\u003cbr\u003e\n310 watts RMS per channel into 8 ohms.\u003cbr\u003e \n470 watts RMS per channel into 4 ohms.\u003cbr\u003e\nBoth channels driven from 20Hz to 20kHz at less than 0.2% total harmonic distortion\u003cbr\u003e\u003cbr\u003e\n\nFREQUENCY RESPONSE\u003cbr\u003e\n20Hz to 20kHz ±0.2dB \u003cbr\u003e\n-3dB at 70kHz\u003cbr\u003e\u003cbr\u003e\n\nDISTORTION\u003cbr\u003e\nTypically \u0026lt; 0.05% THD at rated power\u003cbr\u003e \n0.1% THD and IM worst case prior to clipping\u003cbr\u003e\u003cbr\u003e\n\nCURRENT OUTPUT\u003cbr\u003e\n100A short duration peak per channel \u003cbr\u003e\nFuse protected\u003cbr\u003e\u003cbr\u003e\n\nRISE TIME\u003cbr\u003e\nTypically 5µs\u003cbr\u003e\u003cbr\u003e\n\nPHASE RESPONSE\u003cbr\u003e\n+0° at 20Hz and -14° 20kHz\u003cbr\u003e\u003cbr\u003e\n\nHUM \u0026amp; NOISE\u003cbr\u003e\n100dB below rated output 20Hz to 20kHz, A-weighted\u003cbr\u003e\u003cbr\u003e\n\nINPUT IMPEDENCE\u003cbr\u003e\n47k ohms\u003cbr\u003e\u003cbr\u003e\n\nGAIN\u003cbr\u003e\nRCA Inputs: 32dB \u003cbr\u003e\nBalanced Inputs: 38dB\u003cbr\u003e\u003cbr\u003e\n\nPOWER\/CURRENT CONSUMPTION\u003cbr\u003e\n900W \u003cbr\u003e\n1.6A (370W) Class AB Idle\u003cbr\u003e \n0.2A (46W) Standby\u003cbr\u003e\u003cbr\u003e\n\nDIMENSIONS\u003cbr\u003e\nHeight: 220mm (8 3\/4 \")\u003cbr\u003e\nWidth: 500mm (19 3\/4\")\u003cbr\u003e\nDepth: 455mm (18\")\u003cbr\u003e\nWeight: 38kg (83lb)","brand":"Plinius","offers":[{"title":"Black","offer_id":57415097614668,"sku":"PLINIUSSB301-B","price":8250.0,"currency_code":"GBP","in_stock":true},{"title":"Silver","offer_id":57423838183756,"sku":"PLINIUSSB301-S","price":8250.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Plinius-SB301-B.jpg?v=1777553821","url":"https:\/\/www.stoneaudio.co.uk\/products\/plinius-sb-301-sb301-power-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
