As the company name suggests all their products are of a fully balanced design as, according to Victor Khomenko, BAT co-founder and Chief Engineer - “That’s the only right way to build a circuit”. Our example is in very good condition with a couple of minor blemishes - please see photographs. It is supplied in original factory packaging along with optional remote control unit, manual, allen key, screws, batteries and our standard three month warranty.\u003cbr\u003e\nBalanced Audio Technology Say….\u003cbr\u003e\nBalanced Audio Technology has a 25-year legacy of manufacturing fully balanced tube and solid-state power amplifiers, preamplifiers, and phono preamps. Every BAT product is meticulously engineered to maintain the purity and natural beauty of the original signal and hand-built in our own factory in the US by a small team of dedicated craftsmen and technicians.\u003cbr\u003e\nWhether you choose one of tube or solid-state designs, our goal is achieved using these core principles: fully balanced design is best, dual-mono construction maximizes performance, zero global feedback achieves natural sound, and evaluate for real life performance. All you need to do is listen.\u003cbr\u003e\nThe BAT VK-51SE is a balanced, single gain-stage, tubed line preamplifier, employing no global feedback, providing five inputs, three outputs (2 pre-amplifier and one tape monitor). All inputs and outputs are balanced. There is an \"optional\" remote control.\u003cbr\u003e\nAs with other BAT amplification, the VK-51SE sports the Bat-Pack™ capacitor pack, and a surfeit of power storage (over 300 joules, more than most power amplifiers) AND the VK-51SE offers another Six-Pack™ of by-pass capacitors in the power supply chain.\u003cbr\u003e\nThe 51SE is a full function preamplifier, giving the user significant control over the unit's primary functions from the remote, including programming inputs and setting relative volume for the various inputs.\u003cbr\u003e\nSpecifications:\u003cbr\u003e\nInputs: 5 XLR\u003cbr\u003e\nMain Outputs: 2 XLR\u003cbr\u003e\nTape Output: 1 XLR\u003cbr\u003e\nMaximum Gain: 17 dB\u003cbr\u003e\nVolume Control Resolution: 0.5 dB\u003cbr\u003e\nVolume Control Number of Steps: 140\u003cbr\u003e\nFrequency Response -3 dB: 2 Hz to 300 kHz\u003cbr\u003e\nInput Impedance - minimum each phase: 100 kΩ\u003cbr\u003e\nOutput Impedance: 200 Ω\u003cbr\u003e\nMinimum power amplifier input impedance (with SIX-PAK™): 3 kΩ\u003cbr\u003e\nNoise-unweighted: -110 dB\u003cbr\u003e\nDistortion @ 2 Vrms output: 0.005%\u003cbr\u003e\nChannel to channel crosstalk @ 10 kHz: -95 dB\u003cbr\u003e\nMaximum output signal - RMS: 50 V\u003cbr\u003e\nAbsolute polarity: Switchable\u003cbr\u003e\nTube complement: 8 - 6H30\u003cbr\u003e\nPower consumption: 180 VA\u003cbr\u003e\nDimensions: (W x H x D): 480 (W) x 400 (D) x 150 (H) mm\u003cbr\u003e\nWeight: 18.0 kg\u003c\/p\u003e","brand":"2ndhandhifi","offers":[{"title":"Default Title","offer_id":50986291331413,"sku":"510200038","price":2200.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/1094\/5365\/files\/IMG_7282-scaled.jpg?v=1750866553","url":"https:\/\/2ndhandhifi.co.uk\/products\/balanced-audio-technology-vk-51se-pre-amplifier","provider":"2ndhandhifi.co.uk","version":"1.0","type":"link"}
