Rolls PM50se Personal Monitor Amp

Bring your own signal forward in your headphone mix.

The Rolls PM50se Personal Monitor Amp blends a stereo or mono line-level monitor feed with a microphone or line-level XLR source. Separate Monitor and Mic/XLR level controls let you balance the backing mix against your own signal without changing the main mix at the console.

Two sources, a personal listening balance

Connect a suitable line-level monitor feed to the 1/4-inch input and a compatible microphone or line-level source to the XLR input. A singer can bring their voice forward against the band mix, while a drummer can balance a click source against a monitor feed. The PM50se mixes the sources already connected to it; it does not generate a click track or record audio.

Keep the XLR signal connected to the main system

The XLR pass-through routes the connected XLR source onward to a mixer or other suitable receiving input. It is a pass-through for that source, not an output of the complete headphone mix. Use the local Mic/XLR control to set your listening balance rather than treating it as the main system's channel control.

A ground lift on the XLR through connection can help troubleshoot certain ground-loop problems, but is not a guarantee of hum-free operation. Follow the manufacturer's instructions and do not remove protective AC safety earth connections.

Match the monitor input to your wiring

The 1/4-inch monitor input supports mono or stereo operation with appropriate TS or TRS connections. Follow the manufacturer's mono/stereo configuration instructions: a TRS stereo signal and a balanced mono signal use the connector differently. This input is for line-level audio, not a power amplifier's speaker output.

Headphone connections in two sizes

Both 1/4-inch and 3.5 mm headphone outputs are provided for suitable headphones rated at 8 ohms or greater. These jacks provide the local monitor mix rather than two independently adjustable mixes. Begin with the controls low and increase the level gradually for comfortable listening.

An external power adapter is included. If your microphone requires phantom power, verify the power source and pass-through arrangement with the manufacturer's instructions and connected equipment; do not assume the PM50se supplies it.
