THANK YOU FOR CHOOSING POLSEN.
The Polsen PMA-2B is a stereo personal monitor amplier that lets you create the balance and level that
are perfect for you, whether you’re performing or monitoring. This durable personal monitor features an all-
metal chassis that can withstand travel as well as demanding onstage use or location shoots.
For studio and live musicians, the dual balanced XLR inputs accept the stereo signal from a mixing board.
The high-power headphone output delivers plenty of volume, so even drummers can hear the cue mix over
their drum kits. Film directors and cinematographers who want to monitor the camera’s audio will love the
PMA-2B, which can connect to the XLR outputs of a eld mixer.
