The Wisycom MAT288 is a top-tier antenna matrix that combines and distributes RF for both IEM transmitters and wireless mic receivers simultaneously in a single rack unit. This dual-purpose design eliminates the need for separate combiner and splitter units, saving significant rack space on large touring rigs. It is a premium investment that pays off when you are managing complex RF environments with many wireless channels across IEM and mic systems.

In a single rack unitThe standard slice of rack height: 1U = 1.75″. A 3U box takes three slices; half-rack gear pairs two units side by side in one., the MAT288 handles both directions simultaneously: eight transmitter inputs get combined and fed out to your antenna positions, while the incoming RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping. from those same antennas gets actively split back out to eight receiver outputs.

How it works in the path
At load-in, that consolidation matters more than the spec sheet suggests. You're running BNCThe twist-lock coax connector used for word clock and antenna runs — it locks, so it can’t be pulled out mid-show. to your antenna positions once, not twice, which cuts cable runs, simplifies your stage plot, and removes one complete failure point from the chain. The active design means the split to each receiver isn't a passive loss — the unit's 15-watt draw is doing real work maintaining signal integrity across all eight output legs. With 240mm of depth, it sits comfortably in a standard road case without forcing a shallow-rack compromise. The dual Antenna Out A/B ports give you the flexibility to run a primary and secondary antenna position, which on a wide stage is the difference between clean RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping. coverage and a dropoutA brief audio gap when the radio link fails — the thing diversity, distros, and coordination all exist to prevent. on stage right.

Where it earns its place in the rack
This unit belongs in a rig that's already running six or more wireless channels across both IEMIn-Ear Monitor — earpieces that replace floor wedges, feeding each player their own mix. The reason this whole rack exists. and mic systems, touring in environments where RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping. is genuinely contested — arenas, festival stages, dense urban theaters. At $3,995 it is a significant line item, and a four-channel club rig or a regional act with a simpler wireless footprint will get the same result from separate, less expensive combinerThe transmit-side twin of a distro: merges several IEM transmitters into one antenna without letting them intermodulate. and splitter units. If you're not running Wisycom transmitters and receivers throughout the rack, verify compatibility carefully before committing — this is a premium ecosystem investment, not a universal patch panel.
In the rack
Details worth deciding before load-in.
Label your BNCThe twist-lock coax connector used for word clock and antenna runs — it locks, so it can’t be pulled out mid-show. patch clearly at both the MAT288 and the antenna endpoints — with 16 BNC ports on one faceplate, a mislabeled cable during a dark changeover will cost you time you don't have.
Use the dual Antenna Out A/B ports intentionally: run A to your downstage antenna position and B to upstage or side-fill coverage, rather than splitting further downstream with a passive splitter that introduces additional loss.
Keep the MAT288 toward the middle of the rack vertically if possible — the BNCThe twist-lock coax connector used for word clock and antenna runs — it locks, so it can’t be pulled out mid-show. connections on a full 16-port faceplate are dense, and having elbow room above and below makes cable dressing and mid-show troubleshooting significantly faster.
Budget the 18-watt max draw figure, not the 15-watt nominal, when calculating rack power — active RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping. components can spike on initialization, and a tripped breaker at show time on a loaded power conditionerFilters venue AC, clamps surges, and gives the rack one tidy inlet.

It is a premium investment that pays off when you are managing complex RF environments with many wireless channels across IEM and mic systems.View gear →
GX8The Professional Wireless GX8 is the gold standard for antenna combining on major touring productions, trusted by RF coordinators worldwide. Its active filtering and combining circuitry handles eight IEM transmitter outputs while maintaining clean, intermod-free signal at the antenna. At 2U it takes more rack space than passive alternatives, but the filtering quality justifies it for large-scale shows where RF reliability is mission-critical.View gear →
DISTRO9 HDRThe DISTRO9 HDR is RF Venue's flagship antenna distribution system, offering nine outputs with exceptional dynamic range that handles dense wireless environments without intermodulation issues. Its cascadable design lets you daisy-chain multiple units for very large channel counts. Brand-agnostic and wideband, it works equally well with Shure, Sennheiser, or any other UHF wireless system in your IEM rack.View gear →
AC 3200-IIThe Sennheiser AC 3200-II is the touring-standard active combiner, putting up to eight IEM transmitters on a single antenna with headroom designed for high-power broadcast and arena use. Cascade ports let two units build a 16-channel system, and the robust RF stages keep intermod products down where cheaper combiners fold. If the monitor rack has a rack of SR 2050s in it, this is usually the box underneath them.View gear →
