Dugan Model E-2A User Guide
Linking
Up to eight Dugan units can be linked into a single automatic mixing system. All
digital Dugan models can be linked in any combination. The audio I/O for each must
be configured and connected individually. Linking passes only control information
between Dugans, not audio.
To configure each Dugan for linking:
1. In the Master Pane of the Dugan Control Panel for each unit, click the #ch button
and select the desired number of channels 8–12, or a maximum of 20.
You can also do this from the front panel's MENU > Channels Setup screen.
Do not choose 28 channels because you must leave the LINK IN and LINK OUT
connectors for linking.
2. Power down the Dugan(s).
3. Designate one unit as the master by setting the NORM ↔ SLAVE switch on the back
panel to NORM (up).
4. Designate any other units as slaves by setting their NORM ↔ SLAVE switches on the
back panel to SLAVE (down).
5. Use ADAT (TOSLINK) cables to link units in a ring network.
In the figure below note that all LINK IN and LINK OUT connectors are used to create
the ring.
6. When the connections are complete and the switches are set, power on the Dugans.

can accept power supplies within the range 12–24 VDC, 2 A (minimum), center pin
positive.
Mix Matrix Outputs
An internal mix matrix can route processed or unprocessed inputs to six mix buses
that can be assigned to any audio outputs.
For more information on using mix buses, see Mix Buses on page 49.
