A32pro Series Manual: Cascade Operation / Troubleshooting
Cascade operation via Dante
Cascading of Dante units is done in star topology due to the network structure of Dante. A series connection via the PRI/SEC sockets is
technically possible, but Audinate does not recommend it. A DANTE-compatible network switch is usually used as the star point. In this case,
a series connection is not necessary, although most Dante units have a double network socket. However, this should only be used for
redundant operation. In this case, two separate identical Dante networks are connected to both network sockets (PRI and SEC). If one of the
Dante networks fails, the system automatically switches to the second network. This switching takes place directly in the Brooklyn module
and cannot be influenced externally.
Troubleshooting
Various problem scenarios with approaches to solutions.
Scenario #1:
The unit cannot be switched on
In this case, check the power supply and also connect it to the second PSU input of the A32pro (Dante) as a test.
Also check the output voltage of the power supply under load and replace it if necessary.
Scenario #2:
The signal seems to arrive in the unit, but it does not come out at the intended channel.
First, go to the menu of the headphone listening matrix and select the interface and channel number on which you expect the incoming
signal. If you do not hear the signal there, please check the cabling to the unit and the signal source from which the signal should come as
well as the clock settings of the A32pro Dante. If you can hear the signal in the headphone monitoring matrix, check the ROUTING, GAINS
and LEVELS settings. If this does not help, please perform a factory reset.
Scenario #3:
My signal has periodically constant dropouts (on-off-on-off...)
Periodically regular dropouts often indicate an attempt to link two units in INTERNAL/MASTER/LEADER mode. Since there can only be one
unit in a digital network of several units that sets the clock (INTERNAL/MASTER/LEADER unit), all other connected units must be set to
SLAVE/FOLLOWER. Please note that the A32pro Dante does not come with sample rate converters (SRC) by default that would allow
operation with multiple units set to wordclock master.
Scenario #4:
The signal on the headphones is relatively quiet/weak even in the "full" position.
Make sure that the gain level in the Headphone Setup Menu is set to 0dB. This is the loudest possible level of the headphone preamplifier.
When changing to another system (e.g. IEM) or one with lower impedance and / or higher sensitivity, make sure to set it to a lower value
beforehand!
When daisy-chaining two A32pro (Dante) units via the MADI interface at single sample rates, the MADI channels 33-64 must be routed
„passthru“ to the second A32pro (Dante) in the routing menu of the first device. The settings would be:
MADI Routing Unit #1
MADI Routing Unit #2
In this configuration, MADI I/O channels 1-32 of unit #1
in the chain are routed to the analog I/Os.
At the same time, the MADI input channels 33-64 of unit #1
are routed through to the MIDI output channels 33-64
so that they can be used on unit #2.
On unit #2, the MADI I/O channels 33-64 are routed to the
analog I/Os 1-32. Thus, all 64x64 analog audio
channels of both A32pro units are available.
