The Behringer P2 In-Ear Monitor Amplifier is the powered successor to Behringer’s PM1 personal in-ear monitor amp. The P2 delivers clear audio right to your in-ear monitors with the signal boost of an active amplifier, and it can run up to 12 hours on two AAA batteries (not included). Musicians and performers who require stationary play can benefit from this specially designed belt- or strap-worn in-ear amp, known as the P2. Every part of the P2 has been meticulously engineered to withstand the challenges of the road, ensuring durability and longevity. The overbuilt metal enclosure, smooth rotary volume control, and convenient belt clip are all testament to its durability. The P2 In-Ear Monitor Amplifier uses a standard 3.5mm output jack to drive in-ears, headphones, or earbuds, and it even features an internal switch for selecting mono or stereo use.
