Analog8 solderpads and hacks
The Analog8 buffer module has some solderpads that you can use to change some functions on it.
Disable the 1K output resistor
On the top side of the PCB there are 8 solder-switches near the jacks.
By soldering a short for any of these solder pads, you can eliminate the 1K output resistor for that jack.
The OP’s used for this module are TL074, that has built in short-circuit protection on the outputs.
Therefore, it is possible to do this hack if you need, but it is still better to leave the 1K resistors in place for extra protection.
