Signal Levels
Analog
The Model E-1A requires line level signals in the range -20 to +4 dBm; 0 dBm is optimal.
The
level LEDs light green for normal operation and red for overload.
If there is insufficient gain to keep the
level LEDs lit green when no one is talking, set
the rear panel
LEVEL switch to -10.
Digital
Set the console input gain trimmers so program levels at the insert sends cause the
level LEDs to remain green whether someone is talking or not.
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 3-6 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 below).
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.
