25/70V Speaker(s) with optional 25/70V transformer
The ESS can drive one or more 25/70V Speakers or Horns when
equipped with an optional 25/70V transformer. When using 25/70V
transformers, all speakers must be wired in parallel.
Please note the following guidelines:
•
Each speaker must have its own 25/70V transformer
•
Speakers should be installed within 1500 feet (450 meters) of
the ESS using 18 gauge wire
•
The total wattage available from the ESS must be reduced by
20% to account for line loss
•
The total wattage of the selected speaker taps cannot exceed the
wattage available from the ESS (7.5 watts for PoE, 20 watts for
external power)
•
Maintain the same wiring polarity between speakers
