Please note the following guidelines:
• Each speaker must have its own 25/70V transformer
• Do not mix Speakers tapped for 25V with a 70V distribution line
or speakers tapped for 70V with a 25V distribution line
• All speakers must be wired in parallel.
• Speakers should be installed within 500 feet (150 meters) of the
IP7-FX using 18-gauge wire. For longer runs, increase the wire
gauge
• Each speaker may be tapped differently
• The total wattage of the selected speaker taps cannot exceed the
five watts (12VDC or PoE) or thirty watts (24VDC) available from
the IP7
• Maintain the same wiring polarity between speakers
To use the optional transformer:
• Mount the transformer next to the IP Amplifier
• Connect the J2-6 (SPK R 8Ω+) and J2 - 7 (SPKR 8Ω -) (polarity
independent) from the IP Amplifier to the 8 Ohm side of the
transformer
• Connect the 10 watt tap and common from the other side of the
transformer to the wires leading to the speaker(s)
• Refer to the instructions included with the transformer for
