{"title":"Lundahl Step Up MC","description":"\u003cp\u003eMoving coil cartridges are low voltage devices. Typical output levels are below\u003cbr\u003e1 mV, and often as low as 0.1 mV. In order to generate 12.5W on an 8 ohm loudspeaker, a 0.1V signal must be amplifier 100000 times (or 100 dB). In particular for tube amplifier devices, such a high amplification is very hard to achieve without significant noise additions and signal degradation.\u003c\/p\u003e\n\u003cp\u003eThe purpose of using Moving Coil Step-Up Transformers (MC SUTs) is to step up\/increase the low output signal voltage from moving coil cartridges before the signal enters the phono stage. As MC cartridges are very low impedance devices, transformers can successfully be used to raise the signal level 20 – 30 dB without any noticeable degradation. This reduces the required remaining amplification significantly.\u003c\/p\u003e\n\u003cp\u003eWhen you choose between different MC SUTs, we normally suggest that you choose a step-up ratio based on the cartridge output impedance as follows:\u003c\/p\u003e\n\u003cp\u003eLow impedance (1 – 10 ohms)                     step-up ratio 32 – 24\u003cbr\u003eMedium impedance (10 – 40 ohms)           step-up ratio 24 – 8\u003cbr\u003eHigh impedance (\u0026gt; 40 ohms)                       step-up ratio \u0026lt; 8\u003c\/p\u003e\n\u003cp\u003eLow turns ratio MC SUTs (turns ratio around 1:5) are sometimes used also with low impedance cartridges when combined with solid state phono stages.\u003c\/p\u003e\n\u003cp\u003eLundahl Transformers make MC SUTs with two different types of core; mu metal (nickel) lamination core and uncut amorphous cobalt strip core.  The laminated mu metal core is the most classic and commonly used core material. It provides high permeability also at small signal levels, low distortion and a transparent sound. Our uncut amorphous strip cores are sometimes said to be more musical, but due to a lower initial permeability they are slightly less linear.\u003c\/p\u003e\n\u003cp\u003eOur more prestigious range of SUTs are wound with Oxygen Free Copper (OFC), and some are also available with silver wire.\u003c\/p\u003e\n\u003cp\u003eFor more information on MC SUTs, and how to apply proper loading to cartridges, we suggest you visit this page at our US distributor K\u0026amp;K Audio: \u003ca href=\"http:\/\/www.kandkaudio.com\/applications-guide\/\" target=\"_blank\"\u003ehttp:\/\/www.kandkaudio.com\/applications-guide\/\u003c\/a\u003e\u003c\/p\u003e","products":[{"product_id":"ll1678-lundahl-mc-input-transformer","title":"LL1678 Lundahl MC input Transformer 1+1:16+16 - nucleo amorfo","description":"\u003cp\u003eLL1678 Lundahl Trasformatore ingresso Moving coil (MC) nucleo in AMORFO, 10Hz - 90KHz +- 1db, Rapporto 1:8, 1:16 o 1:32 . per Testine a bassa e media impedenza, ingresso 10-25-150 ohm uscita 10K ohm Rapporto Spire 1+1+1+1 : 16+16 LxPxH mm 30x22,5x14,5 peso 28 gr, (per gli schemi di configurazione\/combinazioni ed altre info vedere il data sheet)\u003c\/p\u003e\n\u003cp\u003eLL1678 is an input audio transformer for moving coil pickups.

The LL1963 transformer combines our dual coil structure with Cardas high purity copper wire in an oversized design. The objective with LL1963 is to provide an alternative suitable for solid state systems, where the classical high turns ratio transformers are not required. The mu metal laminations results in low distortion and a linear magnetization curve. The purpose of the Faraday shield is to make galvanic isolation between cartridge and phono-stage possible.
