rolls A-B Box, Black (PS16)

These are reliable work week to week.. cleans up the stage, and we use it to power 4 of the Rolls headphone amplifiers.. When I first bought these I hooked them up using a TS cable.. I am stupid.. when you use a TS cable, it doesn't transmit any power so all fhte Rolls headphone in-ears amps don't work.. so just make sure you use a TRS cable, the one with two stripes! Other than that it comes with a power supply, just xlr into it from the stagebox trs it to the amps, and there you go you have in-ears for your musicians.

Yes the PS16 Pm is a great product, working as it should with the Personal Monitors! Finding the product affordable, well made, no interference, getting the job done! Would recommend it to anyone using a small to a medium size band! Rolls...thanks for making a great product! Jim and Rob

Good and very useful. Few things to take note. 1. Do not plug any earphones or headphones directly to this unit as it will burn out. 2. Use a stereo Phono cable if you want to power up your Rolls personal monitors from this (You can save the additional adaptors as well as voltage flexibility issues)

Product worked great the one thing I did notice in setup is you must have TRS (tip, ring, sleeve) cables (1/4 inch) if not this will not work it shuts itself off. My church system is Mono so, What I have done with my wired I ear system is split as many cables as I've needed from my aux send and connected to my Rolls PM351s and Behringer Micromons which I highly suggest they are cheap and work really well now if you are mono you will need to adjust to mono but does the same job as the rolls pm50s for half the price.

The power center has been a great addition. I know can send the same mix to multiple in ear user without the lost of power or clear sound. It also build like a tank
