The figure above displays a wiring example of multiple PT2009-A1 being connected to one cabinet. This wiring can be utilized in standard use case only.
All the connected PT2009-A1 share one analog audio input channel. Therefore, only one PT2009-A1 can be active at the same time.
An open circuit outside the cabinet affects all connected PT2009-A1 and a short circuit outside of the cabinet will affect all connected PT2009-A1.
