SSL Live Installation Information
If the clock source is lost, the console will try other clock sources in this sequence: BLII, MADI, video,
AES, wordclock, internal, until it finds a valid clock. The original but lost source will need to be
manually re-selected and applied once it has been reconnected - it will not switch clocks back and
forth automatically in case of an intermittent clock source.
The status bar at the top of the main screen will show a clock source change to warn the operator.
Clocking via a Blacklight II Concentrator
Two consoles may be connected to a Blacklight II Concentrator for sharing a set of stageboxes. The
'Master' console (designated as such by connecting to the Blacklight Concentrator's A ports) will
distribute its clock to the Blacklight system and any stageboxes and consoles connected to it. The
'Slave' console (designated by connecting to the Blacklight Concentrator's B ports) should therefore
set its clock source to the corresponding BLII port on the rear of the console.
The Master console should distribute either its internal clock over Blacklight II (by selecting the Int
option), or one of the external clock source options listed above, with the exception of any Blacklight
port of which it is the Master. Selecting the BLII clock source button will reveal a subset of buttons.
The Slave console should use the Blacklight II option. However, the Master console may use one of
the MADI options if an external MADI source is connected to the corresponding MADI input on the
Blacklight Concentrator. This could be a MADI feed from a third party device providing clock, or
wordlock via a stagebox set to its external wordclock input.
Clocking over Dante
Before proceeding, ensure that the console’s Dante Expander Module, and BLII/X-Light Bridge if
applicable, and any stageboxes or other Dante devices appear in black text in Dante Controller. If the
devices are not visible or visible in red text please see
livehelp.solidstatelogic.com/Help/DanteSetup.html in the SSL Live Help System.
Dante uses its own “Clock Election” process to determine the most appropriate Clock Master for the
Dante network and a Clock Master will be chosen automatically. For more information on the Dante
Clock Election process please see the Audinate website:
dev.audinate.com/GA/dante-controller/userguide/webhelp/#clock_synchronization.htm
To choose a Clock Master manually, set this device to be the “Preferred Master”. To do this, open
Dante Controller and click on the Clock Status tab. Check the “Preferred Master” checkbox for your
chosen Clock Master. This device will become the Clock Master.
If multiple devices on the network are “Preferred Masters”, the Dante Clock Election process will
automatically choose a Clock Master from the multiple “Preferred Masters”.
If the Clock Master’s status changes, or a more suitable Clock Master comes online, the Dante
network will go through the Clock Election steps again to determine the most suitable Clock Master for
the network.
If you are not using Dante network redundancy, please use the primary connection (rather than the
secondary) to ensure accurate synchronisation.
SSL Recommends: SSL recommends that the console is set to clock from the Dante network to
benefit from the Dante clock election process.
Setting up the Console as a Slave of the Dante Network
In this configuration, a Dante device other than the console is the Clock Master. The console and all
other devices on the network will clock to this master.
In Dante Controller, go to the Clock Status tab. Check the “Preferred Master” checkbox for the Clock
Master device(s) if you wish to set one. Dante has its own clock election process, so it is not
necessary to set a Preferred Master. For this example ensure that “Preferred Master” and “Sync to
External” are unchecked for all devices on the network (including the console’s Dante Expander).
On the console, go to MENU > Setup > Options > SYSTEM tab. In the “SYSTEM CLOCK” section,
select Dante Expander and press and hold Apply. Check that both the “Requested” and “Actual”
fields above list “Dante Expander”.
