Solved! Blue tooth power output - jack to amp.

[rayskene]

Does any one know if Bluetooth adaptors output at differing voltages. I have a new base bin with amp. It drives it but very quietly even on max input gain. But my radio mic drives it to max. Perhaps there’s good and bad Bluetooth dongles ???

Yes, and am afraid many BT adapters have the same malady. I blame that everybody want to run these things at 5v because USB power are everywhere. Find an adapter that runs on traditional 12v and I wager u will have better luck with it.
