Rolls PM50S Overview

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. An 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.

I want to run this unit from a battery. Where can I find the male power plug? What size/model am I looking for?
Asked by: Tom
To adapt to a D-tap style battery for example, an adapter such as the LanParte D-Tap to Barrel 12V Regulated Constant Power Cable (17.7"), BH #LADTAP12V can be used. But I would recommend the Rolls PM55P Stereo Personal Monitor Amplifier with Optical Limiter, BH #ROPM55P, which is powered by a 9 volt battery.

question

Is this device is compatible with Pyle Pro Small-Diaphragm Electret Condenser Microphone with 20' XLR to 1/4 cable (B&H # PYPDMIC45 Mfr # PDMIC45)? Thanks.
Asked by: Anonymous
The Rolls PM50s is compatible with the Pyle PDMIC45. You will need to use the mic with a AA battery, as well as an XLR to XLR cable such as the Kopul 3000 series cables. <a href= http://bhpho.to/1ucZjjC target= _blank >http://bhpho.to/1ucZjjC</a>
