Catchbox Plus System

Catchbox Plus System is a professional-grade wireless microphone system for self-service classrooms, hybrid meetings, and events. It combines a 4-channel Hub receiver with integrated DSP and mixer, supporting Catchbox Cube, Clip, and Stick microphones. The Hub connects via USB, Dante, or analog audio, fitting easily into new or existing setups.

You can mix and route audio directly from the Hub without extra DSP hardware, simplifying installations. Each microphone has its own charger and automatically mutes when docked, making the system ideal for shared spaces. With AES-256 encryption, DECT connectivity, and up to 100 m range, Catchbox Plus provides reliable, high-quality sound and intuitive operation.

Key features:

• Connect up to four Cube, Clip, or Stick microphones per Hub
• Built-in DSP and 12-channel automixer for balanced audio
• Dante, USB-C, and analog outputs for flexible integration
• AES-256 encryption and DECT wireless connectivity up to 100 m
• Dedicated charging docks for always-ready microphones
