The 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.

The payoff
Antenna Distro decisions, organized around the whole rig.
The DISTRO9 HDR is RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping. Venue's flagship antenna distroOne pair of antennas feeding many receivers through an amplified splitter — replaces the forest of whips and keeps RF levels consistent., and its job is straightforward: take two antenna inputs and split that signal cleanly across nine receiver outputs so every wireless receiver in the rack sees the same RF picture your antennas do. That's the core promise of any distro, but the HDR designation points at what separates this one — it's built around high dynamic rangeThe span between a device’s noise floor and its clipping point — the room between the quietest and loudest sounds it can pass. circuitry designed to stay clean when the RF environment gets ugly. For anyone running six or more channels of wireless in a single rack, running direct antenna cables to each receiver is both a cable management nightmare and an RF liability. A quality distro is the fix, and this is a serious one.

How it works in the path
Nine outputs in 2UThe 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. at 25 watts means you can feed a full rack of receivers from two antenna runs without fighting for space or tripping breakers. The wideband design means you're not locked into a specific frequency band — run Shure on some outputs and Sennheiser on others from the same pair of antennas without compatibility headaches. The cascadable outputs are the other practical win: if you scale up to a festival rig with 20-plus channels, you can chain a second DISTRO9 HDR off the first rather than pulling new antenna cable or adding a second antenna position. At 260mm deep, it fits comfortably in standard road racks without crowding gear behind it.
