FAQs & How-Tos
-
Using Quantum DUO with our QuantumENGINE software
Unfortunately, our JBL Quantum DUO speakers are not supported by our QuantumENGINE PC software.
All configuration is done on the speakers itself, and there is no need or required software to change the RGB lights.Was this helpful? Thank you for your feedback!

USB connection with Quantum Duo and headphones
Please avoid the use of USB splitters and extenders built into screens etc. Dropouts in sound and lack of signal from the microphone in headsets may be the result. If possible, always connect directly to the computer, or use a single extension cord.
