Q & A

Q1. Can the speakers stay on while plugged in?
A: Yes. Harmony A0 speakers can stay on while connected to power, even when no audio is playing.

Q2. Can I use a microphone for announcements?
A: Yes. Add a compatible Venucast microphone kit to make announcements through your Harmony A0 system. Explore FreeMic Duo →

Q3. Can I group speakers with different transmitters to play separate audio streams?
A: Yes. Each transmitter can use its own broadcast name and password. Grouping syncs the password to supported Venucast speakers so each group joins the correct broadcast. See how Grouping works →

Q4. Can I add more speakers?
A: Yes. You can add multiple compatible Harmony A Series speakers. Harmony 2 speakers are not compatible.

Q5. What if the sound becomes distorted in Bluetooth mode?
A: Update your Oasis Aura transmitter to the latest firmware to improve Bluetooth audio quality. See the update guide →

Q6. Will the speakers work reliably in different rooms?
A: Yes, in spaces with open doorways or lightweight partitions. For best coverage, place the transmitter centrally. Thick, solid walls can block the signal, so test your intended locations before installation.
