Frequently Asked Questions

Will Harmony A3 work with my existing speakers?

It works with powered (active) speakers and amplified audio systems that have a 3.5 mm AUX or RCA input. It cannot power passive speakers directly; passive speakers need a separate amplifier.

Can I add more speakers later?

Yes. The kit includes three AuraLink receivers, and you can add more compatible receivers for additional powered speakers. Actual coverage depends on walls, floors, interference, and transmitter placement.

What can I use as the audio source?

Oasis Aura accepts Optical / TOSLINK, 3.5 mm AUX, and Bluetooth audio. That lets you use sources such as TVs, mixers, computers, media players, phones, and tablets when the corresponding output is available.
