It is sold as a single unit, so a stereo system needs two of them, one behind each speaker. Handbuilt in Canada and convection cooled, with no fans to add noise to a quiet room.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eWhy You'll Love It\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003ePower that does not run out.\u003c\/b\u003e 600W into 8Ω and 900W into 4Ω means demanding speakers and big rooms stop being a problem, and the amplifier stays comfortably inside its limits at normal listening levels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOne amplifier per speaker.\u003c\/b\u003e Running monoblocks gives each channel its own power supply and output stage, which keeps the left and right channels from competing for current on heavy passages.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBuilt to fit your rack.\u003c\/b\u003e Choose a 17 inch or 19 inch faceplate in black or silver, with the 19 inch version adding rack handles for professional installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eUnder the Hood\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePatented Cubed input stage using Bryston's Salomie circuit, with 12 active devices providing the first 6dB of gain and cancelling distortion before it reaches the output section.\u003c\/li\u003e\n\u003cli\u003eBalanced XLR and single ended RCA inputs, switchable 23dB or 29dB gain, input impedance 7.5kΩ unbalanced and 5kΩ per leg balanced, plus a DC trigger input with passthrough.\u003c\/li\u003e\n\u003cli\u003eFrequency response below 1Hz to 100kHz at -3dB, THD below 0.005% across 20Hz to 20kHz at rated power, and microprocessor controlled SoftStart to limit turn-on current.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eCHT Insider Verdict\u003c\/h3\u003e\n\u003cp\u003eThis is the amplifier you buy when the speakers are already sorted and you want to hear what they can actually do. The 7B³ is not a subtle upgrade over a good stereo amp, it changes how a system handles dynamics and bass control. Bear in mind you are buying one channel, so budget for a pair, and leave room for the heat these put out even without fans.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePro Tip:\u003c\/b\u003e Because each monoblock sits beside its own speaker, you can run long balanced interconnects from the preamplifier and keep the speaker cables very short. That is the better way around, and it is one of the real practical advantages of going mono.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\"\u003e\u003cb\u003eConfiguration\u003c\/b\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e1 (monoblock)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold as\u003c\/td\u003e\n\u003ctd\u003eSingle unit (a stereo pair requires two)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\"\u003e\u003cb\u003ePower Output\u003c\/b\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInto 8Ω\u003c\/td\u003e\n\u003ctd\u003e600W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInto 4Ω\u003c\/td\u003e\n\u003ctd\u003e900W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\"\u003e\u003cb\u003ePerformance\u003c\/b\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003eLess than 0.005%, 20Hz to 20kHz at rated power\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal to noise\u003c\/td\u003e\n\u003ctd\u003e-117dB unbalanced, -119dB balanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003eBelow 1Hz to 100kHz, -3dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\"\u003e\u003cb\u003eInputs and Control\u003c\/b\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003eBalanced XLR and unbalanced RCA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput impedance\u003c\/td\u003e\n\u003ctd\u003e7.5kΩ unbalanced, 5kΩ per leg balanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003eSwitchable 23dB or 29dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTrigger\u003c\/td\u003e\n\u003ctd\u003eDC trigger input with passthrough\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\"\u003e\u003cb\u003ePhysical\u003c\/b\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (17 inch faceplate)\u003c\/td\u003e\n\u003ctd\u003e432 x 147 x 394 mm (W x H x D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (19 inch faceplate)\u003c\/td\u003e\n\u003ctd\u003e483 x 147 x 452 mm (W x H x D, with handles)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e24 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCooling\u003c\/td\u003e\n\u003ctd\u003eConvection, no fans\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinishes\u003c\/td\u003e\n\u003ctd\u003eBlack, Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\"\u003e\u003cb\u003eWarranty\u003c\/b\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e10 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Bryston","offers":[{"title":"Black \/ 17 inches","offer_id":48258536407298,"sku":"BRY-7B-BL-17","price":11499.0,"currency_code":"AUD","in_stock":true},{"title":"Black \/ 19 inches","offer_id":48258537816322,"sku":"BRY-7B-BL-19","price":11499.0,"currency_code":"AUD","in_stock":true},{"title":"Silver \/ 17 inches","offer_id":48258537849090,"sku":"BRY-7B-SI-17","price":11499.0,"currency_code":"AUD","in_stock":true},{"title":"Silver \/ 19 inches","offer_id":48258537881858,"sku":"BRY-7B-SI-19","price":11499.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/4376\/1716\/files\/bryston-power-amplifiers-1253159261.jpg?v=1785991451","url":"https:\/\/www.customht.com.au\/products\/bryston-7b-cubed-mono-amplifier","provider":"CHT Solutions","version":"1.0","type":"link"}
