Wisycom MAT288 Antenna Combiner/Splitter

The MAT288 is Wisycom's answer to the question every monitor engineer eventually faces on a large touring rig: why am I running two separate units — a combiner for IEM transmitters and a splitter for wireless mic receivers — when both systems need the same antennas? In a single rack unit, the MAT288 handles both directions simultaneously: eight transmitter inputs get combined and fed out to your antenna positions, while the incoming RF from those same antennas gets actively split back out to eight receiver outputs. One box, both functions, one U of rack space.

At load-in, that consolidation matters more than the spec sheet suggests. You're running BNC 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 RF coverage and a dropout on stage right.

This unit belongs in a rig that's already running six or more wireless channels across both IEM and mic systems, touring in environments where RF 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 combiner 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.
