The Miranda Technologies 2-Channel On-Board ALC (Automatic Loudness Control) is designed for use with the HCO-1822 2 x 1 HD / SD / ASI Change-Over Densité card. When used with the HCO-1822 Densité card, it smoothes out irritating loudness level differences between program segments and between different channels. This ALC option is for the Miranda wideband audio processing algorithms. It can be used effectively to address loudness problems across multiple applications, such as broadcast playout, server ingest, production, and post-production.
The on-board ALC option offers versatile, easily configured loudness processing, which does not adversely affect the program content. It uses a firmware upgrade to the hosting HCO-1822 Densité card. Up to 4 different programs of up to 2 channels can be processed simultaneously, with independent controls and loudness meters on each program. This ALC option leaves the daughter module sockets on the HCO-1822 Densité card free for other advanced processing functions.
