Frequently Asked Questions

Infrared pairing is generally faster and more secure, but requires a direct line of sight between the transmitter and receiver – a potential issue on crowded stages.
Yes, the capsule is replaceable, but options are limited to other Nexadyne capsules designed for the QLXD2 system to maintain compatibility and performance.
You'll generally get a reliable 60-80 feet with the lower power setting, but obstructions and interference can significantly reduce that – higher power increases range but also the chance of interference.
