Speaker Installation Guidelines
•
Each speaker must have its own 70V transformer
•
Connect the speaker’s transformer to the distribution line using
the 70V setting and the appropriate wattage to set the
speaker’s
relative volume
•
Do not mix Speakers tapped for 25V with a 70V distribution line
•
Make sure to maintain the same wiring polarity between each
speaker
•
All Speakers must be wired in parallel (see diagram below)
•
When using transformers, the total wattage available from the
IP7-SS40 must be reduced to account for transformer loss. The
IP7-SS40 has 30 watts available
•
When the wattage settings from each speaker on the 70v
distribution line are added together, the total cannot exceed 30
watts
•
