Lots of heavy metal in the box; transformers, tubes...add some weight to your tone! \u003cbr\u003e\u003cbr\u003e\"The \u003cstrong\u003eGates SA-39B Limiter\u003c\/strong\u003e may be used for all modes of broadcasting, AM, FM or TV nd is designed for very low distortion, wide audio response and as an aid to fine programming.\u003cbr\u003e\u003cbr\u003eThree audio stages stages, all push-pull, employ highly shielded transformers and carefully selected components to assure good balance and low distortion. Limiting action is derived by application of a portion of the output voltage through full wave rectification to the main and second control grids of the first audio stage. As output increases, the grid becomes more negative, lowering the gain of the amplifier.\u003cbr\u003e\u003cbr\u003eTo further assure constant performance under varying line voltages, and electronically regulated power supply maintains constant voltage to the first two audio stages.\u003cbr\u003e\u003cbr\u003eThe recovery time of the limiter is set by a switch on the rear of the chassis. A dial is calibrated for six positions: Position #1 gives a time recovery of .2 seconds, and each succeeding position increases this by .2 seconds.\"\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eInput impedance: 500\/600 ohms\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 500\/600 ohms\u003c\/li\u003e\n\u003cli\u003eInput audio level: -20 to +20 dBm\u003c\/li\u003e\n\u003cli\u003eOutput level: up to +19 dBm\u003c\/li\u003e\n\u003cli\u003eMaximum gain: 50 dB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Gates","offers":[{"title":"Default Title","offer_id":44449891352679,"sku":"55361","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/gates-m3529b-limiting-amplifier-3529003-vintage-5956335_1b39cfae-576b-45ba-a94b-14c3aed98589.jpg?v=1787090837","url":"https:\/\/vintageking.mom\/products\/gates-m3529b-limiting-amplifier-3529003-vintage","provider":"Vintage King","version":"1.0","type":"link"}
