DB2 PRESETS
The following Factory Presets are available with software version 1.25. All presets feature ultra-low
latency loudness correction and true-peak limiting.
Factory presets assume that the AES3-id input is used. If you require analog or SPDIF input, recall
a preset, go to the Engine / I/O page and select the appropriate input. For analog I/O, remember to
adjustthe“Levelat0dBFS”parametertocomplywithyourrequirements.
IfDB2isprocessingforawidedynamicrangeplatform(suchasDTVorinternalstationlinking),the
LimitThresholdontheLimitpagemayberaisedto-3dBFSorevenhigher.ForAC3transmission,
however,theLimitThresholdshouldnotgomuchabove-6dBFStoavoiddistortioninconsumer
devices.
IfDB2isprocessingforalowdynamicrangeplatform(suchasIPTVorMobileTV),theLimit
ThresholdontheLimitpagemaybelowered2-3dB,andtheRatioontheLoudnesspageraised
to 1:4.0 or higher. More pronounced 5-band processing may also be added by bringing down the
“All Threshold” parameter on the 5-band page. With a lower threshold, you may need to prevent the
level from dropping by adding Gain to some or all bands of the multiband processor.
Finally, consider activating the Lo Cut and Hi Cut filters on the Main page.
When you have finished editing parameters, be sure to store the revised settings in one of the User
Banks(U1toU8)ontheLibrarypage.
