Frequently asked questions

How do SuperMAC and HyperMAC handle clock distribution and synchronisation?

SuperMAC and HyperMAC both provide accurate phase-aligned clock distribution. SuperMAC uses separate copper pairs in the Cat 5/Cat 5e cable for audio data and clock, and HyperMAC uses timing markers embedded in the data stream. In both cases this allows reliable, low-jitter clocks to be delivered to the end-points of the system. As digital audio systems develop from the current “islands” of digital electronics connected by analogue cables into fully digital systems, this ability to deliver high-quality clock signals with the audio will become increasingly critical.

Clock synchronisation is very simple to configure, units equipped with SuperMAC and/or HyperMAC interfaces are either master (internally clocked) or slave (externally clocked). All that is necessary to create an operational audio network is to connect up the SuperMAC and HyperMAC interfaces and select the clock source.
