Former Dolby and Orban engineers have designed the Linear Acoustic OctiMax 5.1 digital television audio processor. The system combines the Octiv Octimax multichannel, multiband range-processing engine with audio metadata functionality and local audio insertion capability.
It provides a clean, consistent and appropriately dynamic audio signal for Dolby Digital (AC-3), MPEG or Windows Media 9 Series encoding and transmission to all consumers.
Local audio features include analog and digital inputs and outputs; UpMax, an upmixer that selectively creates a 5.1 channel version of stereo local programming; and AutoVoiceover, which allows control-free insertion of voice-overs by applying local audio to the unit.
The processing structures support eight mono programs, a 5.1 + 2 channel program, and any format in between. The two-channel structure combines a two-band AGC with five bands of compression, look ahead and peak limiting. Advanced multiband source noise reduction is also selectable. The proprietary 5.1 channel structure combines a two band AGC with four bands of compression, look ahead and peak limiting.
The 3RU system contains a color TFT display for detailed metering of the audio channels and processing activity for all programs. A large rotary encoder and four control keys allow for straightforward menu navigation and processing adjustment.
