3 5.1 to Binaural Engage
This preset prepares a 5.1 signal for headphone reproduction through the use of the Engage
algorithm. The algorithm is tuned for AKG240DF headphones, so this selection should be
used as default, and unless another specific model is specified.
Note: Advanced versions of Engage are used for headphone mix optimization and In Flight
Entertainment, and carry License protection. Contact TC Support for a trial version of the
basic algorithm, if you are prevented from recalling this preset.

Engine Bank F11, decade 3: Format Up Conversion for Production Audio
0 UnWrap Dry UnWrap
UnWrap up-converts a stereo or LtRt (matrixed surround) input to a high resolution, 5.1
output. Numerous parameters enables the engineer to get a good result out of most source
material. However, there will be times, where the freedom of a new 5.1 mix based on the
original multi-track material is the best way forward. UnWrap license is required to recall a
preset in this decade.
This preset can be used as a starting point for upconverting material where intimacy needs
preservation, and where the original mix is available using standard downmix coefficients on
the 5.1 signal.
Frontal image width: Solo LCR channels on the Output page when setting Level, Center
channel and L/R processing parameters. Compare against Bypass if you wish to achieve the
same overall image width as the two channel input.
Tip: If you place a Monitor Matrix (preset 11-0-0) downstream of UnWrap, it’s easy to judge
how the processing works, should an end-listener or broadcaster be downconverting the
result using standard downmix principles.
