Two years ago, when we presented the latest innovations in 5.1-capable digital broadcast consoles, we noted that DTV had yet to set the world on fire. Two years later, U.S. broadcasters are still gearing-up for 5.1 broadcast and HDTV systems are still found in only a small percentage of households. But the quality and features of digital mixing systems have made them indispensable to broadcasters, regardless of the audio format being produced. The following information updates that previous guide to include only the equipment and upgrades that have since become available.
