Timecode and Video Reference Signals
To accurately synchronize the MMP-16 to film or video, or with other audio playback equipment, some
method of providing a stable timing reference must be used. Because the MMP-16 is very flexible, there
are numerous methods one could use to connect film and video equipment. The best method depends
upon the chosen method of sync, the other equipment that is being controlled, and whether the MMP-16
will be the master or a slave to the other equipment. This section covers the various reference signals
available on the MMP-16 system and their applications.
Video In/Out
Most video post houses have a common house sync signal to lock all the audio and video equipment in
the facility to a standard video reference signal. This insures that all devices receiving the house sync
signal will lock together to the edge of the video frame. The house sync signal can be black burst,
composite sync, or color bars in NTSC or PAL format. The house sync video reference signal should be
connected to the VIDEO IN connector on the back of the MMP-16. To loop the connection through the
MMP, connect the MMP VIDEO OUT to the next device that will use the house sync signal. If there is
not a loop through connection then the VIDEO OUT may need to be terminated, depending upon the
facility signal design. To set the MMP frame reference to use this video input, choose setup menu 001,
Frame Reference, and set the value of this parameter to be Video Reference.
SMPTE/EBU Time Code In/Out
The MMP has two stereo phone jack connections using ¼” Tip/Ring/Sleeve connectors (with the tip
being + and the ring being - on a balanced signal) for synchronizing the operation of the MMP to other
devices using SMPTE/EBU Longitudinal Time Code (LTC). To synchronize the MMP to an external
device which outputs SMPTE/EBU LTC, connect the time code audio output of the master device to the
MMP TIME CODE IN jack. The MMP-16 can also generate a stable SMPTE/EBU time code output
(equivalent to a time code track signal) that can be used to synchronize external equipment or to stripe
time code onto tape. The TIME CODE OUT jack will always output SMPTE/EBU LTC when the MMP
is playing.
