The PM55P is a unique device for monitoring one’s self and
program material at the same time. It has a monitor level control
and a mic level control, a mic pass-through XLR jack, headphone
output jacks and a switchable stereo/mono 1/4" monitor input
jack.
The PM55P is designed for performers who need to monitor
their own signal, such as their vocals, with the main mix. It is
very popular with drummers who need to mix a click track with
a monitor signal. Church choir singers use the PM55P to moni-
tor their voices over the musicians. Many sound technicians
also use the PM55P as a quick line tester to troubleshoot audio
systems.
The PM55P features all these benets in a convenient, battery-
powered, package.
