The PS16 supplies power and distributes a single Monitor signal to up to eight Rolls PM50se, PM50s, PM55, or PM351’s with only one cable ran to each item. This dramatically increases efficiency and eliminates the need for multiple adapters and cables. The power AND monitor signal are carried from each PS16 output using an ordinary TRS 1/4” stereo cable to the Monitor input of the PM50s, PM50se, PM55, and PM351. Using stereo “Y” adapters, up to eight of the Personal Monitor Amplifiers may be connected.
