The AM10-HD offers a five band AGC followed by a specialized ten band limiter and high performance asymmetrical modulation peak controller algorithm that has been specially designed for the requirements of competitive AM broadcasting. This new peak controller maximizes AM coverage by providing the highest possible average modulation accompanied by consistent positive peak capability of up to 200%. Selectable low-pass filters are available to tailor the output for the requirements of various regulatory needs. The HD signal path includes its own specialized multiband peak controller which has been tailored for the codec that is utilized in AM HD broadcasting.

Vorsis Bass Management System

The Vorsis Bass Management System (VBMS) circumvents bass-related distortion plaguing other broadcast audio processors. It works by monitoring program energy in different parts of the audio spectrum while manipulating the behavior of the final peak limiter. The result is increased bass impact and detail without affecting the clarity of mid and high frequency program — in fact bass detail and the clarity of higher frequency audio are enhanced by the VBMS algorithm.

Smart Stereo Enhancement

Stereo Enhancement is a common feature in audio processors t
oday. However our approach is a new technology we call Smart Stereo Enhancement. It operates in the sum and difference domain and under the management of specialized automatic level and spectral management algorithms. The result is an extremely stable ‘on-air’ stereo image that is wide, alive, exciting to listen to, and yet still natural sounding. End users have reported hearing artistically important nuances in music that were simply inaudible after being processed by competing products.

Spectral Limiter with Adaptive Filter Bank

The AM10-HD’s ten band final limiter reconfigures its crossover frequencies as the AM output low pass filter bandwidth setting is changed, resulting in a very powerful AM audio processor that always has ten bands of final limiting regardless of how narrow the output low pass filter is adjusted. This results in maximum loudness and perceived quality on typical consumer AM receivers. Likewise the five band AGC’s crossovers have been optimized so that all five bands of AGC are available, even down to a 4.5kHz output bandwidth.
