Sync, Video and Time Code Connections

In any digital audio system, it is VERY IMPORTANT all interconnected units are locked to the same
sync reference. A digital audio signal itself can sometimes be used as the master sync source, but a
high stability video or wordclock signal is usually preferable.
The Mykerinos board can be configured inside the Pyramix software to act as either a sync master, or to
slave to a variety of incoming signals.
Decide which device in your system will provide the master sync reference, then ensure that all other
digital audio devices in your system take their synchronization from it. This will require routing appropri-
ate cables --whether digital audio, video or wordclock cables-- to the various other devices and may
also involve a separate sync reference generator and or distribution amplifiers.
If Pyramix is configured as the master (Internal sync), other digital audio devices will probably be able to
lock to the digital audio output from Pyramix. However, Pyramix can also be configured to output a
wordclock signal at the Video output BNC connector (Pyramix Synchronization option required).
If Pyramix is configured as a slave to an external device, Various synchronization signals can be
accepted.
• To lock to incoming digital audio, connect an appropriate digital audio signal to a Pyramix digital
audio input.
• To lock to incoming video, connect an appropriate video signal to the Pyramix Video Reference
input (Pyramix Synchronization option required).
• To lock to incoming wordclock, connect an appropriate master wordclock signal to the Pyramix
Video 2 Input (Pyramix Synchronization option required).
• To set the termination jumpers provided on the Mykerinos board, please see the Mykerinos User
Guide.
Pyramix can either output or lock to incoming SMPTE / EBU time code.
• If a master LTC time code output from Pyramix is needed, cable the Pyramix LTC time code out
RCA jack or XLR to any other devices slaving to this output (Pyramix Synchronization option
required). Pyramix always generates time code when playing.
• To lock Pyramix to an incoming LTC time code signal, cable the LTC time code output from the time
code source to the Pyramix LTC input RCA jack or XLR (Pyramix Synchronization option required).
Pyramix can accept and generate VITC in standard PAL/NTSC formats. It can also provide BITC (Burnt
In Time-Code) on its video outputs.

MIDI Connections

To use Pyramix MIDI functionality with external equipment, you will require a MIDI interface. Many cur-
rent motherboards include an on-board MIDI interface. If yours does not, it is a simple matter to add
one. This can be either an internal PCI card or an external unit connected via a USB port or an RS232
serial COM port.
