Connecting Multiple Speakers
The CFSound-IV can play different audio clips to different speakers, one at a time. This requires
monaural audio clips and one or two Contact I/O 8 modules.
The sound files have the ‘S’ attribute in the filename to activate the associated output contact. One
speaker output is then directed to the desired speaker by connecting it through the output contact. The other
side of all the speakers is wired in common but may not be grounded. Here’s a wiring diagram:
