Audessence AM PRO-1
The Audessence AM PRO-1 is a complete air-chain audio processing system for AM radio stations.
Adjustable input pre-filtering (low-pass and high-pass) pre-conditions audio to prepare for aggressive ‘brick-wall’ low-pass filtering later and avoids wasting modulation percentage on inaudible sub-bass components.
Unsurpassed Audessence AGC developed for the professional Audessence levellers keeps programme level as consistent as desired.
Programme compression, limiting, pre-emphasis and clipping for optimum loudness and coverage increase.
All this plus enhancement features for brightening and clarifying your programme. Adjustable Low-Pass filtering meets all international and national broadcasting specifications, including ITU and NRSC (4kHz to 15kHz nominal).
BENEFITS
• Loud, clean audio for AM broadcasting
• Handles speech just as well as music (not all digital audio processors manage this!)
• Improves audibility and clarity of programme
• Meets all national and international spectral occupancy and other specifications
• Automatically adjusts programme levels if output from studio is too low
APPLICATIONS
• Audio processing for all AM broadcast applications:
• LW
• MW (AM)
• SW/HF
