It does not perform any RIAA functions, it’s a straight gain only.\u003c\/p\u003e\n\u003cp\u003eSUTZ stands for Step-Up Trans Impedance (Z being the symbol of impedance), and is based on the first gain stage of the flagship Sutherland Dos Locos transimpedance phonostage and shares the same chassis as the Little Loco Mk2. \u003c\/p\u003e\n\u003ch4\u003eWho Should Use a SUTZ?\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou have an MM phonostage that you know and love,\u003c\/strong\u003e but want to move up to an MC cartridge. Put the SUTZ in between your table and phonostage, and you can get all the benefits of a low-output MC cartridge (making sure it's also low-Z), but keep your MM phonostage.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou have a low-output MC cartridge that you know and love,\u003c\/strong\u003e a vacuum tube MM\/MC phonostage, and want to reduce tube noise. By putting a SUTZ between your table and the phonostage, you can now switch from the phonostage’s MC input to the MM input, taking advantage of the vastly lower gain that’s needed for moving magnets. This reduces tube noise and lets you use circuits that offer greater tube life.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch4\u003eWhy Not Use a Step-Up Transformer?\u003c\/h4\u003e\n\u003cp\u003eThe SUTZ offers step-up transformer (SUT) functionality but with the benefits of an active transimpedance gain stage. Ron Sutherland has great respect for people who use SUTs, but recognizes that it’s extremely expensive and time-consuming to find the perfect match that's needed between cartridge and SUT. Once you find that perfect combo, there’s more experimentation with load settings and step-up ratios. Add to this the fact that SUTs have a long break-in period during which their characteristics can change.\u003c\/p\u003e\n\u003cp\u003eThe transimpedance nature of the Sutherland SUTZ means you don’t have to worry about cartridge matching. You just need to have a low-output moving coil cartridge with a low (\u0026lt;20 Ohm) impedance. Most MC cartridges are well below this number.\u003c\/p\u003e\n\u003cp\u003eNot only does the SUTZ drastically reduce background noise while giving you all the benefits of an MC cartridge, it also reduces groove noise, creating a very pure, direct sound that is immediately engaging.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (WHD):\u003c\/strong\u003e 17\" x 2\" x 13\"\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 15 lb.\u003c\/p\u003e","brand":"Sutherland","offers":[{"title":"Default Title","offer_id":48545949614264,"sku":"SUTZ","price":4300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/files\/Sutherland__LittleLOCO-Mk2-View2_jpg.webp?v=1741629624","url":"https:\/\/upscaleaudio.pro\/products\/sutherland-tz-active-step-up-transformer","provider":"Upscale Audio","version":"1.0","type":"link"}
