{"product_id":"ps-audio-bhk-pre-amplifier","title":"PS Audio BHK Pre Amplifier","description":"Introducing one of the most remarkable musical instruments in the world, the BHK Signature Preamplifier. This exceptionally built vacuum tube preamplifier opens up the music and reveals nuances, life and space not previously heard on your system. It is the perfect interface between your sources and power amplifier. Designed by Bascom H. King, the BHK Signature distills Bascom’s 50 plus years of high-end audio design experience into a single masterpiece of audio amplification. “This is the best sounding preamplifier I have ever designed or heard,” and that’s saying a lot for a man of Bascom’s experience. Preamplifiers play a critical role in any separates audio system, strategically positioned between sources of music: CD players, phono preamps, DACs, tape recorders and tuners – and your power amplifier – the preamp serves essential roles of control and isolation. Control is simple in concept, but extraordinarily difficult to design in an acoustically transparent manner. Control duties such as input switching, volume, balance, and amplification can place unwanted acoustic thumbprints on the music if not designed with extraordinary care. The challenge in any design is to do as little damage to music’s purity as possible.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:-\u003cbr\u003e\u003cbr\u003e\n\n\nPhysical\u003cbr\u003e \n \nUnit Weight 22 lbs [13.5 kg]\u003cbr\u003e \nUnit Dimensions 14” x 17” x 4” [ 36cm x 43cm x 10cm] \u003cbr\u003e\nShipping Weight 31 lbs [19 kg] \u003cbr\u003e\nShipping Dimensions 20.5”x 24” x 10” [52cm x 61cm x 25cm] \u003cbr\u003e\u003cbr\u003e\n\nPower requirements\u003cbr\u003e \n \nInput Power Model specific 100VAC, 120VAC, or 230VAC 50 or 60Hz \u003cbr\u003e\nPower Consumption 60W\u003cbr\u003e\u003cbr\u003e \n\nAudio inputs \u003cbr\u003e\nCoaxial RCA single ended (5), XLR Balanced (5) \u003cbr\u003e\u003cbr\u003e\n\nAudio Outputs \u003cbr\u003e\nCoaxial RCA single ended (2), XLR Balanced (2) \u003cbr\u003e\u003cbr\u003e\n\nAnalog Audio Output\u003cbr\u003e \n \nConnector  RCA\/XLR Unbalanced \/Balanced (X2)\u003cbr\u003e \nOutput level 4.0 Vrms \u003cbr\u003e\nOutput Impedance \u0026lt; 100Ω\u003cbr\u003e \nFrequency Response 20-20KHz +\/- 0.1dB\u003cbr\u003e\u003cbr\u003e\n \nTHD+N @ 1KHz (full scale) \u0026lt; 0.03% \u003cbr\u003e\nBandwidth -3dB 0.1Hz - 200kHz \u003cbr\u003e\u003cbr\u003e\n\nDC Triggers \u003cbr\u003e\n \n+12V 2 \n","brand":"PS Audio","offers":[{"title":"Default Title","offer_id":57413226037580,"sku":"PSAUDIOBHKPREAMP","price":5000.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/PS-Audio-BHK-Pre-Amp.jpg?v=1777540218","url":"https:\/\/www.stoneaudio.co.uk\/products\/ps-audio-bhk-pre-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
