If you're using a Temple Audio Duo 24 or Duo 34, it makes good sense to position the FM9 very close to the back edge (closest to you) of the Duo board. This will allow the front edge plenty of room for cable bends and feeding the cables through the access holes to the sides, where your modules are.
Although this doesn't protect the sides as much, your audience-facing edge is more protected from mishaps. And to be honest, there may come a time when it might be wise to build a bent metal plate shield that will protect my leading front edge. Although my experience with the FM9 for live venues is still waiting for me to discover, I can safely say that my open-mic gigs won't be the type that might subject my FM9 to potential damage.
Of course, nothing is absolute in this respect, but my open-mics are as heckuva lot tamer than
@Greg Ferguson's. (No offense, Greg.)
My current project involves putting the USB and input jack connections to one side of the Duo 34 with a plate accessory that will house the plugs. That way, any direct connections (USB, input, XLR, power) can occur from the side of the board so as to avoid cable-fouling with onboard pedals or the FM9 itself.
FTR, my Temple Audio XLR > TRS cables were replaced with Monoprice the same length. My onboard tuner connects via Monoprice TS ¼". Likewise my EV-1: Monoprice Gold TRS. They're quality cables, have a lifetime warranty, and don't cost a lot of your hard-earned cash.
