{"product_id":"arcam-arcam-rhead-headphone-amplifier","title":"Arcam rHead Headphone Amplifier","description":"The Arcam rHead is a discrete true linear Class A design analogue headphone amplifier. The rHead is a small, solid and beautifully built headphone amp designed to complement the audio system of any headphone lover.\u003cbr\u003e\u003cbr\u003e\r\n\r\nA pure Class A design delivers absolutely no crossover distortion for the purest sound. Extensive care has been taken by the ARCAM design team to optimise the PCB layout. Multiple, ultra-low noise power supplies as well as a fully direct coupled signal path make for the highest possible performance. The Arcam rHead Headphone Amplifier volume control is an ultra-linear analogue resistive ladder device, as used in the flagship A49 Class G integrated amplifier.\u003cbr\u003e\u003cbr\u003e\r\n\r\nTechnical Specification:-\u003cbr\u003e\u003cbr\u003e\r\n\r\n Frequency response: 10Hz - 20kHz\u003cbr\u003e\r\n\r\n\r\n Total Harmonic Distortion + Noise: 0.001% at 2V output, 32Ω load\u003cbr\u003e\r\n\r\n\r\n Signal-to-noise ratio (A-weighted): 109dB at 2V output, 32Ω load\u003cbr\u003e\r\n\r\n\r\n Power requirements: 12V DC, 1.5A\u003cbr\u003e\r\n\r\n\r\n Headphone output power: 2.0W, 16Ω load\/1.1W, 32Ω load\/0.13W, 300Ω load\u003cbr\u003e\r\n\r\n\r\n Headphone recommended impedance: 16Ω - 600Ω, 3.5 or 6.35mm plug\u003cbr\u003e\r\n\r\n\r\n Output impedance: \u0026lt; 0.5Ω\u003cbr\u003e\r\n\r\n\r\nInput levels: 0-4V (RCA), 0-8V (XLR)\u003cbr\u003e\r\n\r\n\r\n Dimensions: W194 x H44 x D135mm\u003cbr\u003e\r\n\r\n\r\n Weight: 0.71kg\r\n","brand":"Arcam","offers":[{"title":"Arcam rHead Headphone Amplifier","offer_id":57879134437708,"sku":"ARCAMRHEAD","price":165.83,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/s-l225_99f63d47-284a-49da-9aa1-19c851917482.jpg?v=1782310334","url":"https:\/\/www.stoneaudio.co.uk\/products\/arcam-arcam-rhead-headphone-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
