Balanced 4-pin XLR, dual 3-pin XLR and a quarter inch single ended output are all on the front panel, and rear XLR outputs let it double as a line preamplifier. This is a component built to the same standard as Bryston's amplifiers, not a desktop accessory.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eWhy You'll Love It\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eGenuinely balanced, not just balanced sockets.\u003c\/b\u003e A dual mono topology from input to output keeps the left and right channels separate all the way through, which is what balanced headphone cables were designed to take advantage of.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePower for difficult headphones.\u003c\/b\u003e Up to 2W per channel into 32Ω and 20V into 600Ω means planar magnetics and high impedance dynamics both get driven properly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWorks as a preamplifier too.\u003c\/b\u003e Rear XLR outputs and three inputs, including a 3.5mm jack, let the BHA-1 sit at the centre of a desktop or second system rather than hanging off one.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eUnder the Hood\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSix fully discrete Class A Bryston operational amplifiers in a balanced dual mono layout, with a laser trimmed Noble stereo volume potentiometer.\u003c\/li\u003e\n\u003cli\u003eSwitchable 14dB low or 20dB high gain, input impedance 10kΩ unbalanced, with balanced XLR, unbalanced RCA and 3.5mm inputs.\u003c\/li\u003e\n\u003cli\u003eTHD plus noise below 0.005% from 20Hz to 20kHz, signal to noise better than 103dBv, frequency response 20Hz to 20kHz ±0.1dB.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eCHT Insider Verdict\u003c\/h3\u003e\n\u003cp\u003eThe BHA-1 does not flatter headphones when not deserved , it drives them and gets out of the way, so it rewards revealing models and will expose a thin sounding source. The low gain setting matters more than most people expect, and sensitive in-ear monitors are better served elsewhere. If you own a serious pair of full size headphones and a good DAC, this is the amplifier that stops being the limiting factor.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePro Tip:\u003c\/b\u003e Run the low gain setting unless your headphones genuinely need more. You will use more of the volume control's range, which is where a good analogue potentiometer tracks best between channels, and the noise floor stays further down.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003e\u003cb\u003eDesign\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTopology\u003c\/td\u003e\n\u003ctd\u003eFully balanced dual mono\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain stage\u003c\/td\u003e\n\u003ctd\u003e6 discrete Class A Bryston operational amplifiers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolume control\u003c\/td\u003e\n\u003ctd\u003eLaser trimmed Noble stereo potentiometer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003e\u003cb\u003eOutput Power\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInto 32Ω\u003c\/td\u003e\n\u003ctd\u003eUp to 2W per channel at 1% THD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated output\u003c\/td\u003e\n\u003ctd\u003e500mW per channel into 32Ω at 0.005% THD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInto 600Ω\u003c\/td\u003e\n\u003ctd\u003e20V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003e\u003cb\u003ePerformance\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD plus noise\u003c\/td\u003e\n\u003ctd\u003eLess than 0.005%, 20Hz to 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIMD\u003c\/td\u003e\n\u003ctd\u003eLess than 0.001%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal to noise\u003c\/td\u003e\n\u003ctd\u003eBetter than 103dBv\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e20Hz to 20kHz, ±0.1dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003eSwitchable 14dB or 20dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput impedance\u003c\/td\u003e\n\u003ctd\u003e10kΩ unbalanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003e\u003cb\u003eConnectivity\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003eBalanced XLR, unbalanced RCA, 3.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeadphone outputs\u003c\/td\u003e\n\u003ctd\u003e4-pin XLR balanced, dual 3-pin XLR balanced, quarter inch single ended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLine outputs\u003c\/td\u003e\n\u003ctd\u003eRear XLR pair for preamplifier use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003e\u003cb\u003ePhysical\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (17 inch faceplate)\u003c\/td\u003e\n\u003ctd\u003e432 x 69 x 282 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 69 x 282 mm (W x H x D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e5.3 kg\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\n\u003ctd colspan=\"2\"\u003e\u003cb\u003eWarranty\u003c\/b\u003e\u003c\/td\u003e\n\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\n\u003c\/table\u003e","brand":"Bryston","offers":[{"title":"Black \/ 17 inches","offer_id":48258567471362,"sku":"BRY-BH1-BL-17","price":4299.0,"currency_code":"AUD","in_stock":true},{"title":"Black \/ 19 inches","offer_id":48258567733506,"sku":"BRY-BH1-BL-19","price":4299.0,"currency_code":"AUD","in_stock":true},{"title":"Silver \/ 17 inches","offer_id":48258567766274,"sku":"BRY-BH1-SI-17","price":4299.0,"currency_code":"AUD","in_stock":true},{"title":"Silver \/ 19 inches","offer_id":48258567799042,"sku":"BRY-BH1-SI-19","price":4299.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/4376\/1716\/files\/bryston-headphone-amplifiers-1253159224.jpg?v=1785990309","url":"https:\/\/www.customht.com.au\/products\/bryston-bha-1-headphone-amplifier","provider":"CHT Solutions","version":"1.0","type":"link"}
