INTRODUCTION
Introducing DB2
Consistency in loudness levels plus sync of audio to picture: These are the two most important
issues you need to get right in today’s broadcast. They are also two of the reasons why TC Elec-
tronic’sDBrangeofhighdefinitionaudioprocessorshassetthestandardamongstbroadcasters
the world over.
DB2putsallofthetoolsnecessaryfortrouble-freebroadcastingintoonerack-mountableunit,
andaddstoascalablefamilyofprocessorscoveringeveryapplication–fromregionalstationsto
network centers, from podcast to HDTV, from AC3 to linear, and from mono to 5.1.
DB2isthenewsmallerbrotherofDB4andDB8.Itistheperfectchoicefordualmonoorstereo
operation in MPEG, AAC, AC3 or linear audio transmission and linking. Performance is similar to its
biggersiblings,andisalsopresetcompatibleacrosstherange.LiketherestoftheDBfamily,DB2
offers high-quality loudness correction without metadata dependence and is compatible with the
latestITUandEBUaudiostandards.
DB2iscompliantwithITU-RBS.1770-2,EBUR128,ATSCA/85,TR-B32andOP59andenables
one-pass trickle-down from any of those standards to optimum mobile broadcast.
DTV Step by Step
WiththelaunchofDB2,TCElectronicalsointroducesanewcommitmenttobuyersofanyDB
processor:Withintwoyearsoftheoriginalpurchase,usersmayupgradeDB2toDB4orDB8,and
DB4toDB8,atonlythepricedifferenceplusamodesthandlingcost.
For let’s face it: Nobody knows if your audience will prefer stereo, multiple stereo, multichannel, or
somethingelse–sowewanttoensurethatyoucanstayasflexibleandasautomatedaspossible
at a minimum entry cost, yet retain a valuable option to upgrade.
The Transparent Loop
TC Electronic is the world’s premier supplier of automatic loudness correction equipment. It
has developed a high quality loudness range trickle-down concept that works independently of
metadata,butisneverthelessfullycompliantwithmetadatain,forinstance,theAC3codec.DB
processorsnotonlyautomateloudnesscontrolinaproperway–theyalsohelptaketheextra
workload and unpredictable behavior out of the codec.
Appliediningestand/ortransmission,DBprocessorsarepartofatransparentloop,basedonopen
EBUandITUstandards,spanningfromproductionovertransmissiontodeliveryatthehome.Pro-
duction can use metering of any brand compliant with these standards, including TC Electronic’s
LM5D radar meter, and obtain predictable results across broadcast platforms. News, soap, com-
mercial, film, music, promo: All genres are covered.
