This wireless PA system is perfect for events where you need to move around with your microphone and retain the same quality sound you expect from a wired amp. It comes with a wireless mic that operates at a distance up to 100 feet. The amp is compact and lightweight for easy portability. It runs on a rechargeable battery, so you don't need to keep buying new batteries - simply plug in with the included AC adaptor and charge. Adjust the sound to your liking with the treble and bass controls. This amp even includes an echo knob for a wicked sounding voice effect. There's also a ¼" jack input to plug in a wired mic. The wireless mic required one 9V battery (not included). In addition we have added an additional PDMIK4 Dynamic Microphone with Carry Case that makes your voice sound great on the stage or in the studio. It offers a clear, transparent sound and has a neodymium magnet designed for high output - everything you need for crystal clarity. The durable metal construction means this mic is perfect for everyday use. Includes a 15' XLR to ¼" cable. It all fits in the included rugged carrying case. We have also added the PMKS3 Tripod Microphone Stand W/ Extending Boom and PPMCL50 XLR Female to Male Microphone Cable.
