{"product_id":"shure-pa821b","title":"Shure PA821B Eight-Channel Wideband PSM Antenna Combiner","description":"\u003cp\u003eThe Shure PA821B antenna combiner enables monitor engineers and RF coordinators to consolidate up to eight PSM transmitters onto a single antenna set, reducing rack clutter and improving RF distribution efficiency in touring and installed environments. Wideband operation from 470 to 865 MHz supports all P3T, P9T, and P10T transmitter models across multiple frequency bands without retuning.\u003c\/p\u003e\u003cp\u003eA temperature-sensitive fan reduces both acoustic noise and heat output during normal operation, making the PA821B well-suited for installation work where ambient noise control is critical. Eight front-panel LEDs provide per-channel signal presence and overload indication, allowing rapid diagnosis of RF distribution issues during setup and show conditions.\u003c\/p\u003e\u003cp\u003eThis combiner is the logical choice for production teams running multiple PSM transmitters in a single rack, offering measurable improvements in antenna efficiency and system scalability compared to individual antenna deployment.\u003c\/p\u003e","brand":"SoundPro","offers":[{"title":"Default Title","offer_id":52227136520376,"sku":"200188","price":5180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/200188_Shure-PA821B-Eight-Channel-Wideband-PSM-Antenna-Combiner_ALT01sqr.jpg?v=1781296870","url":"https:\/\/soundpro.com\/products\/shure-pa821b","provider":"SoundPro","version":"1.0","type":"link"}
