Broadcast Audio Processors
The Audessence AM PRO-1 is a complete air-chain audio processing system for AM radio stations.
Adjustable input pre-filtering (lowpass 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).
The downloadable brochure was updated in November 2014.
ProCoder-2 is now building an impressive repeat customer list including BBC World Service.
A great value FM processor and stereo encoder that can save money whether your station is a big network keen to solve the dilemma of where to locate your favourite multiband audio processor – or a smaller broadcaster looking to broadcast a loud signal without losing clarity and quality.
Multiband processors can be located at the studio for convenience whilst obtaining better peak control (and therefore more loudness) at one or many FM transmitter sites using ProCoder’s ‘transparent mode’ with LF- and HF- overshoot inhibiting algorithms. All the usual limiting and clipping functions for peak control that you’d expect to find are there too, including fully overshoot compensated 15kHz lowpass filters.
The broadcast audio processor section also has a full range of tools for ‘stand-alone’ use including our world-renowned leveller, plus effective presence and brightness enhancers to make sure your signal stands out. ProCoder delivers typical Audessence clarity and fidelity on voices and music, but this box has the capability to go loud as well!
Top-of-the range ProCoder-3 with integral fully-featured RDS encoder now makes building a high quality, reliable FM system more cost-effective than ever before.
