Timecode sync
Feed a source of external linear timecode (LTC) into the LTC input, or a
source of MIDI timecode (MTC) into the MIDI input. The LTC input is on the
Tip of a TRS ¼” (6.35mm) jack plug with the Sleeve acting as the ground
return.
The BlackBox will indicate on screen how long it is before the next song is to
be loaded and played.
A few seconds before the start time is reached (determined by the Preroll
time setting), the BlackBox will load the audio files for the next song into
memory and will then commence replay exactly as the timecode is reached.
By default, the BlackBox will replay files with respect to the timecode
embedded into the Broadcast WAV file, but is it possible to override this
setting as seen in the example playlist file above – playlist example2.txt (see
page 15). Adding a timecode override allows very subtle adjustment of
replay timings with respect to video for lip sync, etc.
It is also possible to trim the start of a set of audio files by adding a timecode
trim. This feature will commence playback from the trimmed time thereby
editing the start of the cue non-destructively. Trim values can be entered as
an absolute or relative time.
Timed replay
Using the same format of time codes above, it is also possible to trigger
playback from the internal real-time clock such that specific multi-channel
songs are triggered for replay at specific times of day.
This could for example be used to replay different messages at different
times of day throughout a theme park, or to provide messages in multiple
languages at the top of every hour for different radio stations within a large
broadcaster. Use MENU > SETUP and set T
