{"product_id":"copland-cta-305","title":"Copland CTA 305","description":"For low level voltage amplification, valves are in a league of their own with respect to linearity and musicality.\u003cbr\u003eFor nearly a decade, COPLAND has contributed to the refinement of amplification using these classic devices. The CTA 305 employs reliable E83CC valves selected after ageing to assure optimal compability.\u003cbr\u003e\u003cbr\u003eEach class A line level amplifier circuit is divided into two separated non inverting units. This allows us to use a much less complex circuit, with increased stability, and no requirement for internal compensating networks.\u003cbr\u003eDiscrete DC power supply regulates designed for nearly zero output impedance isolate individual gain stages from each other.\u003cbr\u003e\u003cbr\u003eIn addition to the five sets of line-level inputs, the CTA 305 offers a high quality phono level amplifier. For the listener with a large investment in LP's, this amplifier provides an opportunity to recover musical pleasures and more nuances from irreplaceable recordings.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSPECIFICATIONS\u003c\/b\u003e\u003cbr\u003eVacuum tubes\u003cbr\u003e12AX7 \/ ECC83 (4)\u003cbr\u003e\u003cbr\u003eOutput voltage\u003cbr\u003eRated 2V. max 40V\u003cbr\u003e\u003cbr\u003eT.H.D.\u003cbr\u003ePhono - less than 0,1% (output 1V)\u003cbr\u003eCD. line - less than 0,02% (output 1V)\u003cbr\u003e\u003cbr\u003eInput sensitivity\u003cbr\u003ePhono - 2,0mV (output 1V)\u003cbr\u003eCD. line - 300mV (output 1V)\u003cbr\u003e\u003cbr\u003eInput impedance\u003cbr\u003ePhono - 47 K ohms\u003cbr\u003eCD. line - 50 K ohms\u003cbr\u003e\u003cbr\u003eOut impedance\u003cbr\u003eLess than 600 ohms\u003cbr\u003e\u003cbr\u003eS\/N ratio ( IHF-A curve )\u003cbr\u003ePhono - more than 80 dB\u003cbr\u003eCD. line - more than 95 dB\u003cbr\u003e\u003cbr\u003ePower consumption\u003cbr\u003e40W\u003cbr\u003e\u003cbr\u003eNominal mains voltage\u003cbr\u003e115V or 230V factory set for destination country only\u003cbr\u003e\u003cbr\u003eMains voltage range\u003cbr\u003e+\/- 12%\u003cbr\u003e\u003cbr\u003eDimensions\u003cbr\u003e430 (W) 86 (H) 390 (D) mm.\u003cbr\u003e\u003cbr\u003eWeight\u003cbr\u003e7 kg.","brand":"Copland","offers":[{"title":"Default Title","offer_id":57406097260876,"sku":"COPCTA305","price":2415.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/cta305.gif?v=1777452813","url":"https:\/\/www.stoneaudio.co.uk\/products\/copland-cta-305","provider":"Stone Audio","version":"1.0","type":"link"}
