BT chip QCC3008 supports APTX and has low latency. Wireless connection is available within 10 meters.\u003cbr\u003e3.5mm headphone amplifier interface is compatible with ordinary 3.5mm headset. Components uses JRC4556 high power output chip and buffer headphone amp circuit. Headphone Power Output: 30mW@16R, 50mW@32R, 70mW@68R, 70mW@150R.\u003cbr\u003eBuilt-in ESS9023 decoding chip, supports 24Bit sample rate, which integrates a 2Vrms output driver op amp, and has low power consumption.\u003cbr\u003e6K4 tubes can be replaced by 6J1, 6J4, 6AK5 tubes for different listening experience. OP amp 0PA1656IDR can also be replaced by AD827 or MUSE02.\u003cbr\u003eLow Noise: Power supply circuit is separated from other components. With shielded function, interference and noise will be minimized and sound quality will greatly improved\u003cbr\u003eThe LED indicator in front panel show the input. Red LED for RCA input, and blue for BT input. Short press SELECT button can change the signal input. Signal switching uses relay switch which is better than analog power switch.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecification:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eChipset: QCC3008+ESS9023+GE5654+OPA1656IDR +JRC4556\u003cbr\u003eFrequency Response: (±3dB)20Hz-22KHz\u003cbr\u003eInput: BT 5.0, APTX, RCA\u003cbr\u003eOutput: RCA, 3.5mm Headphone Amplifier\u003cbr\u003eLine Output Impedance: Up to 600R\u003cbr\u003eHeadphone Output Impedance: 16-150R\u003cbr\u003eLine Input Impedance: 600R-20K\u003cbr\u003eHeadphone Power Output: 30mW@16R, 50mW@32R, 70mW@68R, 70mW@150R\u003cbr\u003eSensitivity: 0.775Vrms\u003cbr\u003eRCA RMS Level: 2Vrms\u003cbr\u003eBass\/Treble Gain: ±8dB\u003cbr\u003ePower Supply: 12V 1A\u003cbr\u003eUnit Weight: 0.4kg\u003cbr\u003eUnit Size: 98x148x33mm\/3.85 x 5.82 x 1.3 in\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e1 * Preamplifier\u003cbr\u003e1 * Power Cable\u003cbr\u003e1 * Amplifier Antenna\u003cbr\u003e2 * Bulb\u003cbr\u003e1 * User Manual\u003c\/p\u003e\u003cp\u003e\u003cb\u003eNote:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eColor might be slightly different due to the color calibration of each individual monitor.\u003cbr\u003ePlease allow slightly measuring deviation due to manual measurement.\u003c\/p\u003e","brand":"General","offers":[{"title":"Default Title","offer_id":47104417890613,"sku":"77025293","price":7562.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0802\/4188\/5493\/products\/77025293_10_image.jpg?v=1696840297","url":"https:\/\/www.uniqkart.in\/products\/bluetooth-tube-headphone-amplifier-treble-bass-tone-control-silver","provider":"UNIQKART","version":"1.0","type":"link"}
