Depending on the integrated transmission system, some broadcasters may prefer to pass their entire SDI signal through a loudness management system, while others prefer to route only the audio signal through an insert point in their system. TC Electronic, based in Risskov, Denmark, states that its DB6 with unbalanced AES I/O now provides this choice to all broadcasters.

DB6 AES comes fully loaded with 16 physical channels of unbalanced AES I/O, and by default the first 8 channels are active. Should the station need to use additional channels, a license for activating channels 9-16 can be purchased separately.

DB6 AES is an addition to the existing SDI-based DB6 Single and DB6 Multi processors. TC Electronic states that it is not possible to combine SDI and AES I/O within the same unit.

DB6 is a TV and mobile TV transmission processor that handles loudness metering at the input stage, up- and or down conversion at any stage, loudness processing, online lip-sync delay, loudness metering at the output stage and logging of all relevant loudness statistics. The company describes it as an intelligent one-step loudness management solution.

The LoudnessWizard algorithm will take care of loudness correction, up conversion from stereo to surround formats and downmix from surround to stereo. Users apply the LoudnessWizard algorithm and let it combine and properly chain together multiple processes on the fly and without latency. Once configured, it can be left alone to do its work, although the user also may let it know if a program has already been normalized or processed.

Further, the LoudnessWizard algorithm is able to automatically detect the nature of any incoming signal and act accordingly as defined by the engineer. It also integrates multichannel TC Delay, which may be adjusted live without artifacts and used for lip-sync, profanity prevention and loudness processing look-ahead.

TC Electronic’s Radar Loudness Meter handles loudness metering at the input and output stages. It is able to capture the essence of any loudness landscape at a glance for a complete and instant overview that includes Loudness History (S), Momentary Loudness (M), True-Peak Level plus two user-definable parameters such as Program Loudness (I) and Loudness Range (LRA). Both Radar Meters include a Statistics page showing all numbers and details at once.

TC Electronic says that DB6 is compliant with all major broadcast standards, including ITU BS.1770-3, ATSC A/85, EBU R128, ARIB TR-B32, OP-59 and more. It comes fully loaded with presets tailored specifically with each of these standards in mind.
