So, here’s what I have going on. I’m building some prototype Bluetooth speakers, and I picked up a couple of the TSA6013 Bluetooth boards. I’m having an issue with the auxiliary input though in that I can’t use a panel mount 3.5mm jack because if there’s anything plugged into the board, it overrides the Bluetooth audio.
I checked the schematic online, and the PCB shows you can solder wires directly to the board to facilitate using the aux input. I went ahead and soldered wires from a panel mount 3.5 aux jack to the appropriate locations on the board, but no sound comes through when I plug into the aux jack.
To make sure the jack is good, I attached a male 3.5 plug and wire to the back of the panel mount jack and plugged it into the Bluetooth board, which sent audio through just fine. The problem then is I can’t use Bluetooth.
This board is going to be enclosed in a speaker enclosure, so I need a way to make it work. Any suggestions?
Hi @pgutting05
What are you using the Bluetooth board with?
What do you intend to plug in the Aux Input?
To make sure the sound sources aren’t conflicting with each other, when you do plug an input it bypasses the Bluetooth. This is the correct behavior.
The board is currently outputting to an amplifier. The Bluetooth signal works just fine, and I understand that, when you plug into the aux input on the Bluetooth board, it overrides the Bluetooth signal.
My problem is that this Bluetooth board is going to be inside an enclosure, and I would like to have a panel mounted aux jack so that the user can use either Bluetooth or aux. I can’t just solder up a 3.5mm plug to the panel mounted jack and plug it into the Bluetooth board because then the user won’t be able to use Bluetooth since anything plugged into the Aux jack on the board automatically shuts off the Bluetooth audio. I tried soldering directly to the Bluetooth board based on the diagram on the website, but when I plug in an aux it doesn’t work.
Am I missing something?
You could simply mount the 3.5mm with the bluetooth, but have a switch select either bluetooth or 3.5mm. Basically cutting the 3.5mm signals on and off.

A switch won’t work. If anything is plugged into the aux input, even if it’s an open circuit, it overrides the Bluetooth signal. I have tried plugging a 3.5 cable into the aux and cutting it, and the fact that the plug is still in the jack causes the Bluetooth signal to be overridden. Putting a switch in would be no different than cutting a cable or having a panel mounted aux jack.
I’m really wondering why I can’t get an aux signal when I solder directly to the board. I would desolder the aux jack from the board and give it a try that way but it has 8 pins and I can’t find a diagram for what each pin does.
Hey,
It seems there’s no way to do so. TSA6013 can auto detect the Aux in/Line in Audio input. Bluetooth Audio source has higher priority. When Bluetooth audio paused or bluetooth disconnected. TSA6013 will output the Aux in/Line in audio.
They got another model which has the Line source has higher priority, but it is not available right now in RobotShop’s Product catalog.
