Independent power supplies and isolated input signal filter technology reduces high power amplifier energy for a cleaner, transparent power. \u003cbr\u003e\u003cbr\u003e\n\n•Max Power Output: 500W 4 ohms, 250W 8 ohms per Channel\u003cbr\u003e\n•Minimum Load: 2 ohms per Channel\u003cbr\u003e\n•Peak Output Current: 35 Amps per Channel\u003cbr\u003e\n•Balanced Input Impedance: 200 Kohms\u003cbr\u003e\u003cbr\u003e\n\nThe Bel Canto Impedance Optimized Input Stage is a balanced high Common Mode Rejection, low output impedance driver that is critical to the amplifier's performance, ensuring that the refined dynamic qualities of the recording are preserved. \u003cbr\u003e\u003cbr\u003e\n\n The WBT NextGen connectors provide the best possible connection from the amplifier to the speaker cables. We choose them because they impart minimal sonic signature to the sound, remaining open and grain-free up throughout the audio frequency band. \u003cbr\u003e\u003cbr\u003e\n\nMaximum Power Output: 500W 4 ohms, 250W 8 ohms per channel \u003cbr\u003e\nPower Output 1% THD: 400W 4 ohms, 200W 8 ohms per channel \u003cbr\u003e\nMinimum Load: 2 ohms per channel \u003cbr\u003e\nPeak Output Current: 35 amperes per channel \u003cbr\u003e\nFrequency Response: +\/-3 dB 1.5Hz-70KHz, all loads \u003cbr\u003e\nTHD+N: 0.003% 1W, 1KHz, 4 ohms\u003cbr\u003e \nIMD (CCIF): 0.0003%, 1W, 14:15KHz, 4 ohms \u003cbr\u003e\nOutput noise: 35uVRMS A-weighted 10Hz-20KHz \u003cbr\u003e\nVoltage gain: 27dB (single ended or balanced input) \u003cbr\u003e\nDamping factor: \u0026gt; 1000 \u003cbr\u003e\nOutput Impedance at 100Hz: \u0026lt; 8 milliohms \u003cbr\u003e\nDynamic Range: 121dB\u003cbr\u003e \nInput Voltage for Max Output: 2Vrms \u003cbr\u003e\nInput connections: Single-ended RCA or balanced XLR \u003cbr\u003e\nRCA input impedance: 100Kohms \u003cbr\u003e\nBalanced input impedance: 200Kohms \u003cbr\u003e\nOutput connections: 2-sets WBT Nextgen 5-way binding posts \u003cbr\u003e\nPower On usage: 19W \u003cbr\u003e\nPower Off usage: 0.0W\u003cbr\u003e\nInternally Set Operating Voltages: 100-120VAC or 230-240VAC 50\/60 Hz \u003cbr\u003e\nSize: 8.5 x 3.5 x 12[inches], 216 x 88 x 305[mm] (WxHx\u003cbr\u003eD) \nWeight: 15 lbs, 7 Kg \n","brand":"bel canto","offers":[{"title":"Silver Faceplate","offer_id":57414798541132,"sku":"BCANTOE.ONEREF500S-SF","price":2083.33,"currency_code":"GBP","in_stock":true},{"title":"Black Faceplate","offer_id":57423798108492,"sku":"BCANTOE.ONEREF500S-SF","price":2083.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/bel-canto-e.One-REF500S-Silver.jpg?v=1777551558","url":"https:\/\/www.stoneaudio.co.uk\/products\/bel-canto-e-one-ref500s-stereo-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
