Frequently Asked Questions

It's exceptionally clean for a wireless system; the digital transmission minimizes noise and artifacts, getting very close to a wired signal, especially with good quality cables.
The 56 MHz bandwidth provides good channel options, but in exceptionally dense RF environments, you might need to scan for clear frequencies using the app.
The base unit requires a standard power supply, but it doesn't provide power to pedals. You'll need a separate power supply for your pedalboard.
