This MIPRO MA-100SB Portable PA is a single-channel 50W personal PA system that can be slung over your shoulder, thanks to the included strap and handle. This system includes an ACT-32HC handheld microphone transmitter, which gives you a condenser capsule for a silky-smooth sound.

The speaker houses a wireless mic receiver with 16 auto-scanning frequencies with a frequency range of 542 to 566 MHz. It provides a rechargeable lithium battery that lasts up to 10 hours of standby time on a four-hour charge. In addition to receiving wireless audio from the handheld microphone, the receiver sports a 1/4" input for microphones as well as a 3.5mm auxiliary input for compatible media players. You can also stream audio to the speaker over Bluetooth and play audio through the USB 2.0 port. If you want to record whatever you're amplifying, you can also do that through the USB port. 

The rechargeable, handheld microphone syncs easily with the receiver and gives you selectable settings for RF power between 10 and 30 mW. You can power the microphone from two AA batteries. A remote control is included for use with the PA.
