Talkback to a given zone is accomplished by plugging the provided handheld
microphone into the AUX Mic Jack[30] on the DG-MA front panel and holding down
the respective Zone Selector Switch[1]. To talk to all zones at once, press the All
Call Pushbutton Switch[33]. The volume of the talkback audio heard at the zone is
set by the Talkback Level Control [31] on the front of the DG-MA.
INSTALLATION-Mechanical:
The DG-25III and DG-MA units mount to a 19” wide equipment rack. They should be
located away from extreme dampness or heat to ensure long life and reduce
maintenance requirements. Adequate space should be provided around the units
when placed inside the rack to prevent heat build-up due to poor air circulation. The
air must be vented out of the cabinet. The fan's filter filament should be taken out of
the guard and cleaned with warm water after 3 months and replaced every six
months. The filter filament should be cleaned more often when subjected to dust or
dirt. Additional filter filaments can be obtained from Louroe Electronics (part #28-
0074-1.)
