Conditions That Trigger a Source Change in Redundancy Mode
If using Dante, then obviously if the audio network cable is disconnected, the unit will switch
to the backup source, and indicate this by flashing the Primary or Backup selector button for
the appropriate set A/B/C like this:
All four Dante inputs in a set MUST have a subscription for the unit to
consider this as valid signal conditions. If any channel of the set has
its subscription removed (it can be changed but not removed) then all
four are considered as lost and the unit will switch the set to the
backup source (if one is selected).
In AES mode, the same holds true but for pairs of AES inputs — BOTH
AES streams (forming the four inputs) must have a valid AES streams
— loss of clock, or total disconnection of EITHER stream will be seen as
source lost and the unit will switch the set to the backup source. It will
indicate the loss of signal by flashing the Primary or Backup selector
button beneath the AES selection on the appropriate set.
So, in the case of losing both Dante and AES (and so automatically
selecting Analogue), both the Primary and Backup source selector
buttons will be flashing like this:
If the source is restored, the unit will automatically switch back to
the higher priority source and return to normal operation.
Working without Redundancy
If alternate signal formats are not available for your sources, the
unit can be run entirely without redundancy or of course it can be mixed - some sets with or
without as explained the previous example on page 24.
If redundancy is not being used, the other inputs can be used to operate the unit in a different
way, and to simply switch between more sets of four channels, allowing connection of up to 9
x 4 channel sources (assuming 3 of each in analogue/AES/ Dante).
Backup sources are disabled (via the front panel — Backup = Off) and the Primary source
switching is used to cycle between the three signal types to select one of three consoles.
