It features a fully symmetrical and discrete gain stage, balanced 5-pin mini XLR input, and balanced XLR outputs. Adjust settings easily from the front panel, and enjoy clean, interference-free performance thanks to its robust aluminium chassis. Available in silver or black and made in Europe, the Tube Box S3 B is a compact yet powerful upgrade for any serious vinyl setup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\"B\" stands for balanced\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe symmetrical design is the real standout feature! Connect your turntable with the 5-pin mini XLR cable \u0026amp; profit of the balanced signal path. Symmetrical, or also called balanced, transmissions consist of a hot and a cold (also called + and -) signal. Both signal chains effectively carry the same musical information. A true balanced gain stage can now extract the final musical information out of the +\/- signals and subtract, remove, all noise that could potentially be added along the transmission. As there are two separate signal chains, we also needed two individual amplifier sections. Definitely unseen in this price range \u0026amp; the best and cleanest amplifier for your phono signal!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e5-pin mini XLR balanced input\u003c\/li\u003e\n\u003cli\u003eBalanced XLR outputs\u003c\/li\u003e\n\u003cli\u003eFully symmetrical \u0026amp; discrete gain stage\u003c\/li\u003e\n\u003cli\u003eEasy settings adjustment on the faceplate\u003c\/li\u003e\n\u003cli\u003e2x ECC83 tubes (replaceable)\u003c\/li\u003e\n\u003cli\u003eMM \u0026amp; MC capable\u003c\/li\u003e\n\u003cli\u003eDual mono design\u003c\/li\u003e\n\u003cli\u003eSemi-passive RIAA equalisation\u003c\/li\u003e\n\u003cli\u003eSuperior low noise \/ low distortion\u003c\/li\u003e\n\u003cli\u003eAluminium casing protects against interference\u003c\/li\u003e\n\u003cli\u003eAvailable in silver or black\u003c\/li\u003e\n\u003cli\u003eMade in Europe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTube assembly: 2x ECC83 (12AX7)\u003c\/li\u003e\n\u003cli\u003eInput impedance: 10, 50, 100, 1k, 47k ohms\u003c\/li\u003e\n\u003cli\u003eInput capacitance: 50, 150, 300, 400 pF\u003c\/li\u003e\n\u003cli\u003eGain (+ 6dB using XLR Out sockets): 40, 45, 60, 65 dB\u003c\/li\u003e\n\u003cli\u003eSignal \/ Noise ratio MM (40dB): 97dBV, 105dBV - 'A' weighted\u003c\/li\u003e\n\u003cli\u003eSignal \/ Noise ratio MC (60dB): 83dBV, 88dBV - 'A' weighted\u003c\/li\u003e\n\u003cli\u003eTHD at 1 kHz: \u0026lt;0,005% MM, \u0026lt; 0,01% MC\u003c\/li\u003e\n\u003cli\u003eTHD (20Hz-20kHz): \u0026lt;0,1% MM, \u0026lt; 0,03% MC\u003c\/li\u003e\n\u003cli\u003eRIAA-equalization curve accuracy: \u0026lt;0,4dB \/ 20Hz - 20kHz\u003c\/li\u003e\n\u003cli\u003eSubsonic filter: at 20Hz with 18dB\/octave\u003c\/li\u003e\n\u003cli\u003eInput: 1x 5-pin mini XLR \/ 1x pair RCA phono sockets\u003c\/li\u003e\n\u003cli\u003eLine-level output: 1x pair RCA, 1x pair XLR\u003c\/li\u003e\n\u003cli\u003ePower supply DC: 18V\/1000mA\u003c\/li\u003e\n\u003cli\u003ePower consumption: 18V\/800mA DC, \u0026lt;0.5 W in standby\u003c\/li\u003e\n\u003cli\u003eDimensions: 206 x 81 x 153 (164 with sockets) mm (W x H x D)\u003c\/li\u003e\n\u003cli\u003eWeight: 1010g without power supply\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Beatniks Records","offers":[{"title":"Black","offer_id":45369976193103,"sku":null,"price":1149.0,"currency_code":"AUD","in_stock":false},{"title":"Silver","offer_id":45369976225871,"sku":null,"price":1149.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/7530\/8623\/files\/pro-ject-tube-box-s3-b-elektronkovy-phono-predzesilovac-se-symetrickym-vstupem-cerny.jpg?v=1780114479","url":"https:\/\/beatniksrecords.com.au\/products\/pro-ject-tube-box-s3-b-phono-pre-amplifier","provider":"Beatniks Records","version":"1.0","type":"link"}
