Rolls PM55P Personal Monitor Amp+

A personal monitor amp with a built-in optical limiter, the Rolls PM55P blends a performer’s own microphone with the monitor mix in their headphones.

Vocalists use it to hear themselves over the main mix, and drummers use it to mix a click track with a monitor signal. It also works as a quick line tester for troubleshooting audio systems.

The XLR mic input has a hard-wired pass-through jack that sends the mic on to the mixer and passes phantom power with no voltage or signal loss. That jack has a ground lift. The PM55P does not supply phantom power itself. A switch sets the mic input for mic or line level, and the 1/4-inch monitor input switches between stereo and mono.

Separate mic and monitor level controls set the blend, and the limiter switches off for a full bypass. The 1/4-inch and 1/8-inch headphone outputs work at the same time. It runs for 10 to 30 hours on one 9-volt battery, alkaline preferred, or on the included Rolls PS27s power supply with the battery left in.
