The Gator GTSA-Mix 12PU is a rack system and a rugged ATA flight case in one. You can mount a mixer up to 12U in size, throw it in a van or check it on a plane, and set up at the venue in seconds. The rack rails ratchet upward to put knobs and faders where you need them. Alternatively, if you have a mixer that's smaller than 12U, Gator gives you leftover space to mount a headphone amp, outboard FX, recording interface, or power conditioner and leave everything routed for a turnkey live and recording setup. Best of all, the GTSA-Mix 12PU is built tough to keep your gear safe wherever you go.
