The PS16 supplies the DC power
and distributes the Monitor signal to up to ten of the PM50s, PM50sOB, PM55, PM55P, and PM351
units by connecting them with ordinary stereo
phone cords. Although the PS16 has only 4 output jacks they can be multiplied with "Y" adapters for many more outputs. This makes a much "cleaner" installation and eliminates the need for multiple
wall-warts and adapter cables etc.
