from the “Preferred Leader” on the Dante network. All other devices on the network are clocking from
the “Preferred Leader” on the Dante network.
Note that if selecting Dante as a clock source on the console, the console clock backup scheme will
not drop back to another clock source if the Dante network clock is lost. The Dante Expander module
incorporates an internal clock which will become the Clock Master of the Dante network as determined
by Dante's clock election process until another device on the network is identified as a more suitable
Clock Master.
Important:
It is not recommended to clock from Dante if the Dante
SRC In
is engaged.
Consoles clocked from stageboxes via MADI or Wordclock are not recommended to be used as Dante
network Clock Master sources.
Setting up the Console as a Master of the Dante Network
By setting the console’s clock source to internal (or a non-Dante external source) and the Dante
Expander module to “Preferred Leader” and “Sync to External” in Dante Controller, the console can be
made master of the Dante network.
However, due to Dante's clock election process, any device subsequently connecting to the network
which is also set to Preferred Leader and has a lower MAC address than the console will be elevated
to network Leader Clock. In this scenario the console and Dante network clocks will no longer be in
sync and could cause loss of audio.
SSL therefore recommends that this configuration is not used as it does not offer network
clock redundancy.
Clocking over a BLII/X-Light Bridge
As detailed in the previous section, SSL recommends that the console is set to clock from the Dante
network (follower mode) to benefit from the Dante clock election process. This should be done using
the local Dante Expander port as described above, even if using a BLII/X-Light Bridge. Provided both
the console and BLII/X-Light Bridge remain clocked to the Dante network they will remain
synchronous.
If configured correctly the following LEDs will be seen on the BLII/X-Light Bridge:

Setting the Sample Rate
The Live system can run at 96 kHz (recommended) or 48 kHz sample rates. Use the
96 kHz
and
48 kHz
buttons in the System page (
MENU
>
Setup
>
SYSTEM
) to change the console's sample
rate. The stageboxes must also be changed to match the console's sample rate; see below.
Aside from the FX Loop and optional Dante module interfaces, decreasing the sample rate to 48 kHz
does not increase the total input/output count; each MADI port carries 64 channels at 48 kHz but
odd-even MADI port pairs are always redundant (even-numbered ports on twin card Blacklight
Concentrator are disabled).
Important:
Changing the console's sample rate will interrupt audio and cause routes to be dropped
as stagebox configurations will need to be changed. Muting all outputs to switch sample rate and for a
further 30 seconds is recommended.
