25/70V Speaker(s) with optional 25/70V transformer

The SS40 can drive one or more 25/70V Speakers or Horns when

equipped with an optional 25/70V transformer. This is the

recommended installation method when driving multiple speakers.

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 3000 feet (900 meters) of

the SS40 using 14 gauge wire

 The total wattage available from the SS40 must be reduced by

30% to account for transformer and line loss

 The total wattage of the selected speaker taps cannot exceed the

wattage 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 (SPKR 8Ω+) and J2-7 (SPKR 8Ω-) from the IP

Amplifier to the 8 Ohm side of the transformer

 Connect the 40 watt taps from the other side of the transformer

to the wires leading to the speaker(s)

 Refer to the instructions included with the transformer for

additional information

 25/70 volt systems should be installed within 3000 feet (900

meters) of the SS40 using 12-18 AWG depending on the length

of the wiring run
