The resulting four-wire audio plus RS-422 data can then be sent to a Clear-Com Matrix port, ber-optic converter (modem) or connected to another EF-701M over twisted-pair cable such as CAT-5E. When used with a Matrix system, the EF-701M allows a party-line channel to be connected to the frame with up to 5000 feet of cable. With its excellent hybrid null and wide-range level controls the unit may also be used as a best-quality stand-alone two-to-four-wire converter.\u003c\/p\u003e \u003cp\u003eFor travelling systems that require long connecting runs between stations or systems, EF-701M’s can quickly recover their cost in space and weight savings, as ber-optic and UTP cables are lighter and more compact than standard shielded mic cable. Two EF-701M’s can be connected directly to each other over low-cost four-pair, unshielded, twisted-pair cable (UTP). The EF-701M ’s low prole and compact size add to its portability. It can easily be mounted on a utility rack shelf and up to three units will t across in a standard 1-RU rack space. No additional power connection is required, as the EF-701M obtains its DC operating current through the party-line connection on pin-2 of the XLR connector.\u003c\/p\u003e ","brand":"HME Electronics, Inc dba Clear-Com, LLC","offers":[{"title":"Default Title","offer_id":51438898938040,"sku":"31408","price":1120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/31408_Clear-Com-EF-701M-Encore-Audio-Conversion-4-Wire-Interface_ALT03.jpg?v=1782419090","url":"https:\/\/soundpro.com\/products\/clear-com-ef-701m","provider":"SoundPro","version":"1.0","type":"link"}
