Proel U24B 2.4GHz USB Wireless Bodypack Microphone System

The Proel U24B is a professional wireless microphone system designed for high-definition, interference-free transmission over the 2.4GHz band. Its ultra-compact USB receiver draws power through the USB interface and incorporates a dual-mode audio interface that automatically detects connections to analogue and digital devices.

Plug-and-play operation requires no driver installation. The receiver can connect directly to a PC or Mac for recording into a preferred DAW application. A suitable USB Type-A adapter can also be used to connect the system to iOS or Android devices for standalone digital applications.

The receiver is also compatible with Proel equipment featuring a USB WIRELESS input. Intelligent Frequency Hopping helps maintain a stable connection while avoiding interference from television stations and other broadcast equipment, and the transmitter pairs with the receiver automatically.

The system includes a bodypack transmitter and a double-ear headset microphone.
