The PM50s is a small footprint device that provides a mix of a stereo line-level signal with a microphone level signal, and outputs the mix to two sets of headphone outputs. The unit features a monitor level control, microphone level control and pass through XLR jack, two headphone output jacks, and a stereo 1/4" TRS monitor input jack. The external power adapter is included.
The PM50s is designed for performers who need to monitor their own signal, such as a singer who needs to hear their vocal over a main mix. Other uses include drummers who might need to mix a click track with a monitor signal, or church choir singers who need to monitor their voices over other musicians.

Comments about Rolls PM50s - Personal Monitor Amplifier:
I'm a keyboard player using the PM50s for my live stage monitor mix. I bring a stereo feed of my keyboards from my stage mixer into the "monitor in". The other instruments in my monitor mix are fed into the balanced "mic in" from the house mixer aux channel. The balance between my keyboards and the vocals can be quickly adjusted via two separate knobs.

I Purchased this product to provide in-ear monitors to the other musicians in my church's worship band. They are solidly built and sound incredible. They provide both 1/4 and 1/8 headphone inputs and can also be used to monitor your voice or anything mic'ed. Love everything about them. Ohh...I almost forgot..they are incredibly cheap for what they give.

Wow, this works really well. I bought it for the band at our church. Makes it very easy for someone who plays an instrument or sings to have a decent in-ear monitor without spending a fortune.
Very solid all-metal construction. Setup and use are very simple; the diagrams & labels silk-screened onto the top make it easy to see what should plug in where.
I highly recommend the optional MSC106 mic stand adapter if you're using this on stage.
Only drawback is that you need a long cable or an extension for your ear monitor / headphones. If you mount this on a mic or music stand, you don't have a lot of room to move.
We'll be buying a mix of these and the 2-channel PM351 to move our whole band to in-ear monitors.

Comments about Rolls PM50s - Personal Monitor Amplifier:
We use these headphone amps / personal monitors for our keyboards and guitar instrumentalists at our House of Worship. They are a high quality inexpensive alternative to wireless IEM that work well for stationary performers. Being able to control their own volume independently of the separate monitor mix ensures they can always hear themselves as loud as they want. This also allows us to reduce the overall volume of the stage monitor speakers.
Great product at a great price.
