To execute a power-up Reset command, hold the channel 1 bypass button down dur-
ing power-up. This sets all parameters to factory default settings and clears label text.
We recommend executing a Reset command (just like “zeroing out” a console) before
starting a new installation.
Linking Multiple Dugans
Up to eight Dugan units can be linked into a single automatic mixing system. One
unit must be set to be the master and the others slaves.
Figure 2-3 Linking multiple Dugans
1. Designate one unit as the master by setting the NORM-SLAVE switch on the rear
panel to NORM (up).
2. Designate any other units as slaves by setting their NORM-SLAVE switches on the
rear panel to SLAVE (down).
3. Use ADAT (Toslink) cables to link units in a ring network (see above).
Note that all LINK IN and OUT connectors are used to create the ring.
NOTE: Due to the Model E-1A’s compact size and close spacing of the ADAT connectors, some large
cables may not fit. The maximum cable width is 0.48 in (12 mm).
NOTE: Linked Model E-1s appear in group a only. Linked Model E-1As can use groups a–c.
Operation
1. Raise your console preamp gains until the Model E-1A’s green level LEDs stay illu-
minated when the room is quiet.
The level LED illuminates green when the input level is within the acceptable
range for automatic mixing and flashes red to indicate clipping. There should be
enough gain ahead of the Model E-1A to maintain the green LED at all times.
