The power tubes are heated with direct current (DC) with a special circuit designed to separate the tubes heating from audio path powering. Power supply for anode voltages is designed on semiconductor and based on MOFSET transistors and low-noise current sources.\u003cbr\u003eOn the XLR balanced inputs, symmetrical audio-grade Lundahl transformers have been\u003cbr\u003eused. Audio source selection is made using high end relays (low signal relays), which are placed directly behind the input connectors, in order to limit interference and noise.\u003c\/p\u003e\n\u003ch2\u003eIN THE BOX\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMatched pair of driver tubes CV-181(6SN7)\u003c\/li\u003e\n\u003cli\u003eMatched pair of power tubes 300B\u003c\/li\u003e\n\u003cli\u003eAC cord\u003c\/li\u003e\n\u003cli\u003eUser Manual\u003c\/li\u003e\n\u003cli\u003eWarranty Card\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSPECIFICATIONS\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eClass A Single-ended transformer coupled amplifier\u003c\/strong\u003e\u003c\/p\u003e\n\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower tubes:\u003c\/strong\u003e 300B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver tubes:\u003c\/strong\u003e PsVane CV-181 mk2 (6SN7)\u003c\/li\u003e\n\u003cli\u003e2x unbalanced RCA inputs (IN1, IN2)\u003c\/li\u003e\n\u003cli\u003e1x balanced XLR input (IN3)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput sensitivity:\u003c\/strong\u003e 1V RMS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput impedance:\u003c\/strong\u003e\u003cbr\u003e– For IN1 i IN2 (RCA) 100kΩ\u003cbr\u003e– For IN3 (XLR) 10kΩ\u003c\/li\u003e\n\u003cli\u003e1x pair of pre-amplifier output as RCA\u003c\/li\u003e\n\u003cli\u003e1x pair of pre-amplifier output as XLR\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMaximum voltage on the above outputs is 5V (RMS) at output impedance of 600Ω and THD\u0026lt;0,5%\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance selector guidance:\u003c\/strong\u003e\u003cbr\u003e– LO – up to 60Ω\u003cbr\u003e– MID – up to 300Ω\u003cbr\u003e– HI – up to 600Ω–mnh\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier’s impedance:\u003c\/strong\u003e\u003cbr\u003e– LO at 32Ω load is 3,8Ω\u003cbr\u003e– MID at 100Ω load is 8,8Ω\u003cbr\u003e– HI at 600Ω is 20Ω\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOutput powered measured at MID impedance setting at load of 16Ω is 5W with THD ⩽1% (maximum 8W at THD \u0026gt;5%)\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e\u003cbr\u003e– 8Hz÷100kHz ±3dB\u003cbr\u003e– 18Hz÷40kHz ±1dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone outputs:\u003c\/strong\u003e 6.3mm and XLR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC voltage 50\/60Hz:\u003c\/strong\u003e\u003cbr\u003e– 230V version (±5%)\u003cbr\u003e– 115V version (±5%)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption:\u003c\/strong\u003e 110VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 15,1kg (without packaging)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003cbr\u003e– 35x33x18,5cm (LxWxH) – without tubes\u003cbr\u003e– 35x33x24,5cm (LxWxH) – with tubes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Feliks Audio","offers":[{"title":"American Walnut","offer_id":47478680649961,"sku":"Envy Performance-American Walnut (USA, 120V) (OB)","price":8999.1,"currency_code":"USD","in_stock":false},{"title":"Oak","offer_id":47478680584425,"sku":"Envy Performance-Oak (USA, 120V) (OB)","price":8819.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/5_f2cf56a7-eded-4bac-8a39-e1d1d434c66a.png?v=1762466573"}],"url":"https:\/\/audio46.mom\/collections\/feliks-audio.oembed","provider":"Audio46 Headphone Store","version":"1.0","type":"link"}
