Behringer P1 Powerplay The Behringer P1 Powerplay is a personal In-Ear-Monitor (IEM) Amplifier. Giving you all the control where it’s most useful, right at your fingertips. So whether you’re on stage or in the studio, the P1 Powerplay offers a dependable and affordable personal monitoring system. Furthermore, using the P1 Powerplay also helps to protect your hearing in two ways. Firstly, the built-in current limiter is “drummer proof”, preventing unexpected peaks in the signal from getting to your ears. While the simple act of wearing In-Ear-Monitors can help isolate your ears from the loud stage volume of your instrument amps. Using the P1, you can clearly hear your own performance while blending in the ideal amount of volume for the rest of the band. Additionally, dual XLR inputs allow for 2-channel mono or stereo operation. Overall, the Behringer P1 is the perfect amplifier for monitoring your IEM’s.
