I bought this to use in a dedicated monitoring rack to have outputs to FOH from two microphone splitters used as input, but assumed turning it backwards would be no problem (the inputs are in front, I needed them in the back with the outputs in front). Luckily it was possible by dismantling it and turning the internal PCB with the connectors around and putting it back together, although the screws that secure the PCB to the chassis would no longer fit as they are not in the middle but offset towards the back. Fortunately that shouldn't matter much since the 64 screws in total that secures the connectors to the chassis should be enough. Still though, I'd like to see it be slightly more flexible, perhaps by having the ears on separate brackets that can be turned around (like the ART P16 patchbay has).
Regardless, this unit is way cheaper than the ART P16, so I guess I can't complain, and it does suit my purpose after doing my own modification.
