Orban Optimod DAB 6300 Audio Processor

Orban's new PreCode™ technology manipulates several aspects of the audio to minimize artifacts caused by low bitrate codecs, ensuring consistent loudness and texture from one source to the next. There are several factory presets tuned specifically for low bitrate codecs.

In sound-for-picture applications, the 6300's built-in CBS Loudness Controller™ tames source-to-source loudness variations, ensuring consistency and maximizing audience satisfaction.

Because of its versatile signal routing, the 6300 can be used as a combined studio AGC, digital radio/digital television/netcast processor, and low-delay talent headphone processor. Any of its three outputs (stereo analog x1; AES2 digital x2) can emit any of the following signals:

• Stereo enhancement, equalization, and AGC without look-ahead peak limiting
• Stereo enhancement, equalization, and AGC with peak limiting
• Stereo enhancement, equalization, and multiband processing (2-band or 5-band, including AGC) without peak limiting
• Stereo enhancement, equalization, and multiband processing (2-band or 5-band, including AGC) with peak limiting

In a typical application:

• The 6300 substitutes for the AGC in an Optimod at the transmitter and provides protection limiting for the STL. Digital output #1 emits the peak-limited output of the AGC to drive the STL. The AGC is turned off in the transmitter-side Optimod
