{"product_id":"atlasied-tsd-hf11","title":"AtlasIED TSD-HF11 Paging Horn Crossover and Limiter Module","description":"\u003cp\u003eThe AtlasIED TSD-HF11 is purpose-built for installed paging applications where signal conditioning between a source and paging horn is critical. System integrators and AV installers working on commercial, campus, or industrial paging deployments will find this unit addresses the common need for band-pass filtering and power limiting in a compact, rackmountable form factor. Its 1-in\/1-out architecture keeps signal routing straightforward while the onboard controls provide meaningful flexibility for tailoring the unit to specific horn and amplifier pairings.\u003c\/p\u003e\u003cp\u003eThe TSD-HF11 supports both balanced and unbalanced inputs, making it compatible with a wide range of signal sources without additional adapters. Independent input and output trim controls allow precise level matching across a system, while the variable limiter prevents excess signal from reaching the amplifier — extending equipment life and maintaining intelligibility in high-SPL paging environments. Selectable low-cut filter frequencies (200Hz, 300Hz, or 400Hz) via dip switch give technicians the ability to tune horn response on-site without additional external components.\u003c\/p\u003e\u003cp\u003eDesigned to work within the broader TSD ecosystem, the TSD-HF11 supports multi-unit installations powered from a single supply using the TSD Power Calculator for current planning. Security covers on all front panel controls protect settings from tampering in public or semi-public installations. Optional rack mount kits are available for clean panel integration in equipment rooms or head-end racks.\u003c\/p\u003e","brand":"Atlas Sound, L.P. - Mitek","offers":[{"title":"Default Title","offer_id":52445850271928,"sku":"20008","price":353.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/20008_ATLAS-TSD-HF11_ALT01sqr_72e787a8-a740-46f9-a87f-c1c2ab553999.jpg?v=1783457406","url":"https:\/\/soundpro.com\/products\/atlasied-tsd-hf11","provider":"SoundPro","version":"1.0","type":"link"}
