I’m wondering if there us option to use the Coax out port on the Khadas Tone 2 Pro as LFE out for subwoofer?
I am currently using the T2P as. Preamp to my 2.0 amp for my bookshelf speakers. I have a active subwoofer without low level input/output. If i can send signal to it with the coax on the T2P that would be better than buying some splitters. Anyone try with success?
Coax out Port is the yellow balanced RCA,it can be used as a S/PDIF output by special firmware.If your subwoofer has RCA as S/PDIF input,you can have a try.And you must use our balanced RCA plug,the signal is defined as the following picture.
I am not sure that your subwoofer has 3.5mm Aux-in or 4.4mm Aux-in,if it has one of them,I suggest you can connect it to Tone2 Pro by 3.5mm to 3.5mm cable or 4.4mm to 4.4mm cable.
You should make a BAL RCA to unBAL RCA cable by yourself.
Buy BAL RCA plug from this website.Notice,you should choose the plug of BAL RCA,not the jack.
Buy an unBAL RCA,we have not recommended about it.
Buy a single core wire with ground shield.
Connect the 2nd pin of BAL RCA to the 1st pin of unBAL by the center wire,and connect the 3rd pin of BAL RCA to the 2nd pin of unBAL RCA by the ground shield.
Then you should upgrade the XMOS firmware which it has S/PDIF output by Khadas Tone DFU tools.
But the firmware is for test,not official version,it may have some problems,the S/PDIF out is OK,you can have a try.
Hi
No,mono RCA cable is unuseful,because the mono RCA cannot connect S/PDIF Out to your subwoofer. But you can modify it to an useful cable,you should cut down one side RCA plug and change it to BAL RCA.
i understand, i’ll get an order for one. I tried installing the firmware, however it seemed to have bricked the device. I am getting solid light blue light and no detection. I tried other computer but it still is not be detected.
Hi
Oh,that is because the MCU firmware of your tone2 Pro is too old,you should update the MCU firmware by ST-Link.The method you can learn from this video.The MCU firmware you can download from here as the following picture shown.
