Putting control right where it’s most useful – at the artist’s fingertips, the POWERPLAY P1 Personal In-Ear Monitor (IEM) Amplifier from Behringer features a high-power headphone output that ensures when the band gets louder, you’ll still be able to hear every nuance of your performance. Its simple user interface makes it easy to dial-in your ideal mix each and every time. Employing the P1 can also help protect your hearing: thanks to its built-in current limiter, unexpected peaks in signal level won't get to your ears. Its dual XLR inputs allow 2-channel, mono, or stereo operation with a convenient mix function that enables you to run 2 sources into the unit and set up exactly what you want to hear as you perform. Two simple controls, Level and Balance, let you instantly achieve your ideal mix. It runs on a single little 9V battery that can last up to 12 hours, so it'll go pretty much as long as your next show or studio recording session. Or, for the ultimate in dependable power, you can use the optional PSU-SB DC power supply (sold separately). Additionally, its metal chassis is built like a tank to handle even your most-demanding and energetic performances. Small enough to hang on your belt – or mount on a mic or drum stand, the P1 puts complete balance and volume control in your hands.
