{"product_id":"stage1-pa421b-e","title":"Shure PA421B-E Antenna Combiner with PSU for PSM IEM","description":"The Shure PA421B-E is a professional 4-to-1 RF antenna combiner with integrated DC power distribution for Shure PSM in-ear monitoring transmitters (not compatible with PSM200). By feeding up to four transmitters into a single, high-quality antenna output, it reduces aerial clutter, minimises intermodulation risk and helps deliver cleaner, more consistent RF coverage across stage and venue spaces. Centralised power simplifies deployment: multiple PSM transmitters can be powered from the unit, cutting down on IECs, mains strips and cabling in the rack.\n\nEngineered for reliability in touring and fixed installations, the PA421B-E offers robust build quality, dependable RF performance and straightforward BNC connectivity for quick, repeatable setups. The European “-E” variant ensures region-appropriate power compliance, making it a practical choice for EU productions, rental fleets and integrators.\n\nIdeal for live sound, broadcast and corporate events, the PA421B-E streamlines IEM infrastructure, helping engineers tidy racks, optimise antenna placement and improve monitoring stability. A smart, space-saving solution whenever multiple PSM transmitters need to operate cleanly from a single antenna.\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePower supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE1.1.100.999\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"SHURE","offers":[{"title":"Used Equipment","offer_id":57367037870457,"sku":null,"price":1999.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/I0002569_2NDHAND-B_a.jpg?v=1780406730","url":"https:\/\/stage-experts.com\/products\/stage1-pa421b-e","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
