Dugan Model E User Guide Quickstart

Step 3 Linking Multiple Units

All linked units must be in analog audio I/O mode and use analog connections to the

board because linking requires the digital I/O connectors. Up to eight Model Es (64

channels) can be linked into a single system that maintains the gain of one mic from the

room no matter how many mics are connected. One unit must be the master and the oth-

ers slaves.

Set the NORM-SLAVE switch on the rear panel to NORM (up) to designate that Model

E as the Master. Set the NORM-SLAVE switch on the rear panel to SLAVE (down) to

designate that Model E as Slave.

Link units in a ring configuration as shown below. Note that all LINK IN and OUT con-

nectors are used to create the ring.

Step 4 Operation

Raise your console preamp gains until the Model E’s green level LEDs stay illuminated

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 to maintain the green LED at all times.

NOTE: When the green light goes out, the channel is in a downward expansion mode

to avoid feedback. This condition should be avoided because the smooth am-

bience characteristic of Dugan automatic mic mixing is lost.
