It is in good condition, with a few minor blemishes and will come supplied in original factory packaging with mains cable, manual and our usual three month warranty.\u003cbr\u003e\nBryston Say….\u003cbr\u003e\nAdvancing our tradition of unmatched audio performance and functionality, the BHA1 is Bryston’s reference amplifier solution for the finest listening experience from your headphones. The BHA 1 is compatible with both traditional (single-ended) and balanced headphones.\u003cbr\u003e\nThe advantage of powering each headphone driver (right and left) with two amplifiers configured in balanced or series mode is a doubling of the signal voltage to each speaker. This design configuration has been the foundation of Bryston’s legendary 7B, 14B and 28B amplifiers and now headphone users can experience the same dramatic resolution from the BHA-1. The Bryston BHA-1 employs the vast benefits of balanced amplifier designs that are inherently clean and stable especially when there is a demand for higher power and\/or a difficult load to drive.\u003cbr\u003e\nBecause most headphones are not balanced devices, Bryston provides a traditional (unbalanced) ¼-inch input on the BHA-1 as well as inputs for balanced headphones. Bryston will also provide modifications to some headphone models to make them compatible with a balanced output configuration, along with an adapter cable assuring backwards compatibility to all traditional (unbalanced) headphone outputs.\u003cbr\u003e\nFeatures:\u003cbr\u003e\nBalanced Dual mono circuitry\u003cbr\u003e\nHigh Quality Noble Stereo Volume control - laser trimmed\u003cbr\u003e\nLeft\/Right Balance Control\u003cbr\u003e\n6 Fully discrete Class A Bryston operational amplifiers\u003cbr\u003e\nBalanced outputs – 4 pin stereo and dual left\/right 3 pin outputs\u003cbr\u003e\nStereo ¼ inch single ended outputs\u003cbr\u003e\n14dB or 20dB of selectable gain available\u003cbr\u003e\nAll input and output connectors are Gold plated\u003cbr\u003e\n10k input impedance\u003cbr\u003e\nMultiple headphone drive capability\u003cbr\u003e\nSpecifications:\u003cbr\u003e\nPower Output (continuous): Maximum: 2 Watts per channel into 32 Ohms at 1% THD; Rated: 500 milliwatts per channel into 32 Ohms at .005% THD\u003cbr\u003e\nInput Impedance: 10 kOhms single ended (unbalanced); + 15\/- 5 kOhms double ended (balanced)\u003cbr\u003e\nSensitivity: HI (approx. 20 dB) setting: 70 mV in = 100 mW out into 50 ohms (500 mV in = 5 V out); LO (approx. 14 dB) setting: 140 mV in = 100 mW out into 50 ohms (500 mV in = 2.5 V out)\u003cbr\u003e\nDistortion: THD+N: \u0026lt; 0.005% 20 Hz to 20 kHz; IMD: \u0026lt; 0.001% 60 Hz + 7 kHz mixed 4:1\u003cbr\u003e\nNoise: Measured with input shorted (20 Hz to 20 kHz) \u0026gt; 103 dB v (with 20 Hz to 22 kHz band pass filter)\u003cbr\u003e\nFrequency Response: 20 Hz to 20 kHz @ ± 0.1 dB\u003cbr\u003e\nPower Bandwidth: \u0026lt; 1 Hz to over 100 kHz\u003cbr\u003e\nPower Consumption: 50 Watts\u003cbr\u003e\nDimensions: 432 (W) x 282 (D) x 69 (H) mm\u003cbr\u003e\nWeight: 5.3 kg\u003c\/p\u003e","brand":"2ndhandhifi","offers":[{"title":"Default Title","offer_id":50986442719573,"sku":"1886","price":835.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/1094\/5365\/files\/IMG_1419-scaled.jpg?v=1750870407","url":"https:\/\/2ndhandhifi.co.uk\/products\/bryston-bha-1-headphone-amplifier-silver","provider":"2ndhandhifi.co.uk","version":"1.0","type":"link"}
