The 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.
The 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.
Designed 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.
