Selecting Synchronization Method
Choosing a Synchronization method may be done through either the Web UI, or
the Front Panel LCD.
From the Front Panel the synchronization mode may be selected from the
System Clock submenu, under System Settings. If sync bus is selected, the
interface will prompt the user with a choice of Internal or External clock mode.
Through the Web UI, synchronization mode can be set on the System
Configuration page. In the table on the bottom right of that page are two
dropdown menus. The first is for the synchronization mode, the second will
only be shown when the synchronization bus is selected and allows to select
the 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.
When selecting the synchronization bus, the interface will prompt the user with
a choice of Internal or External clock modes. Only one Internal can be set for
the sync mode; this 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.
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.
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. Shield should be connected to ground, the signal wire should be
connected to "Sync". The wire connection between the furthest "External"
system and the "Internal" system must not exceed 300' (90 meters).
