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
•The following guidelines should be used for selecting Speaker
