About Anchor Audio LIB-7500MU1

The Liberty LIB-7500MU1 from Anchor Audio is a powerful portable PA system that operates on an internal rechargeable battery, or on AC power. It features a single built-in wireless microphone receiver that enables you to easily add an Anchor Audio wireless handheld or clip-on microphone. With multiple inputs for wired microphones and the ability to add the separately available LIB-7501 external companion speaker, the Liberty is the ultimate easy to transport PA system.

The Liberty system was designed to be a great sounding PA system that sets up quickly and can be used without training. Its internally rechargeable battery allows you to use the Liberty for several hours away from a power source. There are a lot of useful features built into the Liberty, like the speech projection button that improves the voice intelligibility, a built-in limiter that reduces distortion and battery status LEDs.

The built-in MP3 player features an SD Card slot, a USB port and a mini-plug input. You can save some MP3 files on an SD Card, load it into the slot and play them from the Liberty and even set songs to play on repeat.
