The T10S does not offer the option to disable the standby function.
This is only possible with our alternative products like the SUB7/8/10/12.
We kindly ask you for your understanding that we do not offer remote assistance for modifying our products.
If the subwoofer unintentionally switches off during operation, we would recommend increasing the input level.
For the best signal-to-noise ratio, we generally recommend that you adjust the input volume you use to drive the Sub as loud as possible (without clipping the input of the T10S) and then turn the volume down accordingly.
It is technically possible that the subwoofer switches to standby even if a signal is present.
This happens when the threshold of the sub is not reached for a longer period.
Please bear in mind that this threshold was chosen with care, as the sub should not switch on accidentally or unintentionally in case of slight background noise or voltage peaks.
