Speaker Wiring - Whelen Engineering Company IPS 400 Product Manual

5.6 Speaker Wiring

All of the speakers
connections are made through the
System Driver Board, located on the
left side of the back wall of the IPS
cabinet.
The upper most terminal block is
TB1. It is the connection point for
the audio signals to the speakers (for
direct connect speakers) or to the
speakervisors (for
speakers). Refer to the drawing.
Starting at the top, notice that the
terminals are in pairs, 1 through 8.
Also notice that each pair has a (+)
terminal and a (-) terminal. Each
terminal pair can drive up to 100
watts, therefore, speaker
greater than 100 watts must be
distributed through more than one
terminal pair.
TB2 is not used.
TB3 is not used.
Remember to keep track of the audio
cables and cable polarity. The audio
cable must be connected to the
proper polarity at each speaker.
