Hello All,

As the title says, my PreSonus Eris 3.5 BT right speaker doesn't work in Bluetooth mode, but it does work with AUX and TRS. I have tried other devices and it is the same. I have also tried using other Bluetooth speaker or headset and it works just fine. I am just having the problem only with this speaker. Can anybody help? Thank you very

Maybe a stupid question but ... Did you pair the speakers using the specific switch behind the main one ?

i have the same problem . i hope someone from Presonus to answer cause this problem is annoying .

to solve this problem i try to change the power cable but does work. i suppose the problem come from one on this :


RF interference
Output-current limiting
Turn-on/off transient
Subsonic filter
External mains fuse


 there are moments when i  hear a few minutes music adn after no power stay for a few seconds and the sound come back .

I have the same problems...
My presonus Eris 3.5 BT have the same problem as described...
My Android 10 device can not "re"-connect to the speakers.

Its always necessary to renew the pairing... and even sometimes -my smartphone shows that the speakers are connected- when i start music on the smartphone the local speakers are used!

so i would say the Bluetooth of the speakers do not work at all.
