The NEW! OPTIMOD-DAB 6300 is a high-quality, multipurpose stereo audio processor for digital radio, digital television,netcasts, STL protection, audio production, and digital mastering. With 20 kHz audio bandwidth and 48 kHz internal sample rate, the 6300 is Orban’s next generation to the popular OPTIMOD-DAB 6200 audio processor, while offering improved processing algorithms and more flexibility. The 6300 contains a stereo enhancer, AGC, equalizer, phase-linear multiband compressor/limiter with either two or five bands, and two independent stereo look-ahead peak limiters. Peak limiting can be “flat” or preemphasis-aware at either 50 or 75 microseconds, allowing
the 6300 to protect preemphasized analog STLs. For video applications, broadcasters can activate the 6300’s included CBS Loudness Controller to prevent audience irritation and tune-outs caused by loud commercials. The 6300 incorporates Orban’s new PreCode technology, which pre-processes audio to minimize audible artifacts in low bitrate codecs such as the iBiquity HDC codec used in HD Radio. Several of the 6300’s presets exploit this technology to provide “plug and play” processing at low bit rates.
