integration into the speaker enclosure (I-PAM bulk).

I-PAM system diagramThe I-PAM receives power and 8 different audio signals
in addition to bi-directional control data from the Digital Speaker System (DSS) bus. It selects and amplifies two
audio channels from the bus for play-out via the connected speakers.
In addition, trigger inputs and outputs, and control interfaces on the I-PAM, allow building a complete
