About the Seismic Audio SA-RMSS-32

Thirty-two channels of transformer-isolated splitting in a 5U chassis. The "no compromises" rig pick — every drum mic, every backline DI, every vocal mic has its own direct + iso trunk to FOH and a recording rig, with margin left over. Heavy enough that you only carry it when the rig calls for it.

The SA-RMSS-32 is the answer to a specific and serious question: how do you feed 32 channels simultaneously to FOH and a second destination — a recording truck, a broadcast feed, a monitor world running its own console — without creating a ground-loop mess or loading down a microphone that a vocalist is counting on? Each of the 32 inputs gets both a direct output and a transformer-isolated output, so you have 64 total output paths leaving this box. That transformer isolation on one leg of every channel is the whole point; it breaks the ground reference between two consoles that may be drawing power from entirely different parts of a venue.

Five rack units and 10.4 kilograms tells you this is not a throw-in-the-fly-pack unit. At load-in it will want its own dedicated trunk space and two people lifting it into position. The zero power draw is a real operational benefit — no IEC cable to chase, no power strip slot consumed, no thermal concern in a packed rack. The 220mm depth is manageable in most standard road cases, but measure your rails before you commit. With 96 XLR connectors populated at show time, patching this unit is its own task; build that time into your advance.

This box belongs in a festival-advance or touring splitter rack where the channel count genuinely reaches into the thirties and two or more consoles need to work from the same mic lines without argument. If your show is a 16-channel club rig or a corporate event with a single FOH console, you are carrying 10 kilograms of hardware you do not need. For those situations, a 16-channel splitter or a smaller passive split solution is the honest answer. Where the SA-RMSS-32 earns its place is the situation where the alternative is running two separate mic runs to the stage — and nobody wants to do that.

In the rack

  • Assign the direct outputs to whichever console holds phantom power responsibility — typically FOH — so phantom passes through unimpeded; the isolated outputs go to the secondary destination where phantom is blocked by the transformers.
  • Color-code your snake tails before the gig: one color for the 32 inputs from stage, a second for the 32 direct runs to FOH, a third for the 32 isolated runs to the split destination. With 96 connectors live, unlabeled cable is a real troubleshooting problem mid-show.
  • At 10.4 kg this unit shifts the rack's center of gravity meaningfully — rack it low and towards the back of the case to keep the overall pack balanced when rolling it on casters.
  • Build a channel-by-channel continuity check into your line check routine; with this many connectors, a single misseated XLR is easy to miss visually but will surface fast when you try to ring out a channel at FOH.

32-channel transformer-isolated splitter — festival-grade.
