device will be the clock source to all synchronized systems. All other devices
need to be set as External, and use the clock signal of the Internal.
Through the Web UI, synchronization mode can be set on the System
Configuration page. In the table on the bottom left of that page are two
dropdown menus. The first is for the synchronization mode, and the second
for setting the system as Internal (Primary on the Executive HD) or External
(Secondary Mode on HD) clock mode.
Synchronization Bus
The synchronization bus allows connecting several Executive Elite Base DSP
units together to manage the clock between the systems.
The Synchronization bus also allows synchronizing Executive Elite Base DSP
units with Executive HD™ receivers in the same vicinity. While the
synchronization bus in Executive HD installations also managed group mute
control, this capability is handled differently in Executive Elite. When installed
together with Executive HD systems the bus will therefore only provide
synchronization data, not mute data between Executive Elite and Executive HD
systems. However, mute groups managed between Executive HD systems can
still be managed using the bus.
The synchronization bus cable is connected to the grey Euroblock BUS
connector on the Executive Elite Base DSP unit using a standard 3.5mm
Euroblock connector. The wire used should be 26AWG or better, shielded
cable. The distance between the furthest External and the Internal must not
exceed 300’ (90 meters).
The terminals of the BUS connector should be wired in parallel via either a
daisy chain connection or terminal block split. The three contacts of the
Euroblock connectors are as follows from left to right.

G. Ground
If the synchronization bus is used to synchronize Executive Elite
systems with Executive HD systems, one of the Executive HD systems needs to
be set as the Internal, making that system the clock master. All Executive Elite
Base DSP units will have to be set to use the external clock.
AVB Synchronization
If all Executive Elite Base DSP units are connected to the same AVB network,
the AVB network can be used to synchronize the systems with each other.
This simplifies installation of Executive Elite systems as no additional
