Frequently Asked Questions

While it supports multiple frequencies, Band D’s limited channel availability means coordination is crucial to avoid interference in a crowded RF environment.
Yes, the balanced XLR output makes it suitable for a variety of instruments, but the TQG connector is specifically designed for guitar/bass-style cables.
Higher-end models offer wider frequency bands, more channels, potentially better range, and often include rechargeable battery packs—at a significantly higher price point.
