Orban/CRL says an upgraded DSP board for the Optimod-FM 8500 is available that produces up to 16.4 seconds of diversity delay in HD Radio installations, making the 8500 compatible with Exgine-based exciters.

The original 8500 hardware produced up to 8.2 seconds of delay, which the company says was adequate for earlier generations of HD Radio transmission hardware.

The upgrade only benefits stations using new-generation HD Radio hardware that prevents them from matching their analog and digital channel delays. Other stations do not need the upgrade, which does not affect other 8500 features.

Additionally, any 8500 can be retrofitted with a new DSP board. Suggested retail price of the upgraded board is $950.

Orban/CRL also says the Orban Optimod 6300-DAB multi-purpose stereo audio processor for digital broadcast is shipping. The unit also is suitable for digital satellite, STL protection, netcasts, audio production and digital mastering.

Highlights include PreCode technology, which pre-processes audio to minimize audible artifacts in low bit rate codecs, and soft knee and compression ratio controls for each of the bands in the multiband compressor/limiter, which Orban says allows engineers to apply subtle multi-band compression while retaining as much of the original source's dynamics as needed.
