At its heart beats the latest version of the LIFES 1.1 amplification circuit. Derived from the LIFES circuit first introduced in the M-10X in 2021, this latest iteration has been further optimized to reduce distortion even further and improve overall performance.\u003c\/p\u003e\n\u003cp class=\"wp-block-paragraph\" style=\"text-align: left;\"\u003eThe B-100 Centennial adopts a new ‘4×4’ output configuration, consisting of four triple-stage Darlington push-pull modules in a quad-parallel arrangement for each channel. This configuration delivers 25 W in pure Class A at 8 Ω and 125 W in Class AB. At 4 Ω, the power doubles to 250 W and quadruples at 2 Ω to 500 W. Capable of reaching up to 1,000 W peak power at 1 Ω, it aims for total linearity and absolute control over the speakers, reinforced by a damping factor exceeding 1,000.\u003c\/p\u003e\n\u003cp class=\"wp-block-paragraph\" style=\"text-align: left;\"\u003eThe main reason for the doubling of power output each time the impedance is halved is the power supply, which relies on a massive, custom-built, high-efficiency 1,250 VA EI-type transformer, featuring flat copper windings to reduce losses and improve coupling. This is combined with 16 filter capacitors of 10,000 μF each (totaling 160,000 μF), which provide a considerable energy reserve. The ‘peel-coat’ circuits are gold-plated without varnish and combined with specific inductors and numerous relays.\u003c\/p\u003e\n\u003ch2 id=\"key-specifications\" style=\"text-align: left;\"\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable style=\"margin-left: 0px; margin-right: auto;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated output\u003c\/td\u003e\n\u003ctd\u003e125W (8Ω) \/ 250W (4Ω) \/ 1,000W (1Ω, bridged)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e20Hz–20kHz (+0 \/ -0.1dB), 1Hz–180kHz (+0 \/ -3.0dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal harmonic distortion (THD)\u003c\/td\u003e\n\u003ctd\u003e0.0014% (1kHz \/ 8Ω)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eS\/N ratio\u003c\/td\u003e\n\u003ctd\u003e119dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput impedance (unbalanced)\u003c\/td\u003e\n\u003ctd\u003e51kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput impedance (balanced)\u003c\/td\u003e\n\u003ctd\u003e55kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower consumption\u003c\/td\u003e\n\u003ctd\u003e180W (rated) \/ 440W (maximum) \/ 1.0W (standby)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e440W × 243H × 651D mm (including feet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e59.5kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2 id=\"three-stage-power-supply-design\" style=\"text-align: left;\"\u003eThree-Stage Power Supply Design\u003c\/h2\u003e\n\u003cp style=\"text-align: left;\"\u003eThe B-100 CENTENNIAL features a three-stage power supply architecture:\u003c\/p\u003e\n\u003col style=\"text-align: left;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003ePowerVault RAW\u003c\/strong\u003e: Large-capacity capacitor bank for instantaneous current delivery, handling abrupt musical dynamics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStabilized high-voltage rail\u003c\/strong\u003e: Clean, stable power for the input stage with minimal noise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual low-noise control rails\u003c\/strong\u003e: Independent power supply for precision servo circuits and control sections\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp style=\"text-align: left;\"\u003eThis design prevents power supply fluctuations from entering the signal path even during high-output operation.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eThe amplifier is also capable of delivering 1,000W into 1Ω when bridged, making it suitable for driving large loudspeakers or unusual load conditions.\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e","brand":"Dedicated Audio","offers":[{"title":"Default Title","offer_id":51787086332221,"sku":null,"price":29995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0653\/5587\/files\/1_74b6cdc1-0e49-4dc6-911e-f677f6e63d5a.webp?v=1780481233","url":"https:\/\/www.dedicatedaudio.com\/products\/luxman-b-100-centennial-mono-power-amplifier-each","provider":"Dedicated Audio","version":"1.0","type":"link"}
