IEM Transmitter

Shure ADTD Axient Digital PSM Dual TX

The Shure ADTD is the dual-channel transmitter of the Axient Digital PSM platform: two stereo IEM channels of wideband digital RF with Dante and analog inputs, networked control, and the spectral efficiency that lets big shows stack channels where analog PSM could not. It is the direct successor tier to the PSM1000 and the unit users requested by name. Pair with ADXR bodypacks and an antenna combiner.

01 · What it does—and what that changes in your rig.

Product overview

Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.

The payoff

IEM Transmitter decisions, organized around the whole rig.

The ADTD is Shure's answer to what happens when a big IEM rig runs out of clean spectrum — it is a dual-channel Axient Digital PSM transmitter, putting two independent stereo IEM feeds in a single rack unit. Each channel gets its own pair of analog combo inputs plus four channels of Dante on both primary and secondary EtherCon ports, so you can feed it from a digital console's Dante network, an analog split, or both simultaneously as a redundant source. This is the platform-level successor to the PSM1000, and it carries that pedigree into wideband digital RF with the spectral efficiency that lets large shows stack more channels than analog systems could realistically manage.

Function

How it works in the path

At load-in, the RJ45 control port and Dante integration mean this unit lives on your network — frequency coordination, gain, and monitoring all happen through Wireless Workbench or ShurePlus Spectrum tools without touching the front panel once it is dialed. The single BNC RF output means you are running this into an antenna combiner or active distro before it reaches your antennas; plan that patch bay accordingly. At 25W nominal draw across both channels in a single rack unit, you can comfortably stack several of these in a conditioned rack without stressing a 20A circuit, but confirm your combiner and distro headroom first. The ADXR bodypack is the intended receiver partner.

Best fit

Where it earns its place in the rack

If you are running six or more IEM feeds, managing a touring rig that moves into unknown RF environments regularly, or building a system where digital Dante routing eliminates analog stage splits entirely, the ADTD earns its $4,455 price. The dual-channel-per-U density alone justifies the cost on large shows where rack space is as scarce as clean spectrum. If you are doing a three-piece band with stable local RF and no Dante infrastructure, the capital outlay is hard to justify — a PSM300 or PSM900 system will do the job for considerably less. This is a production-touring and installed-venue piece, not a weekend-warrior transmitter.

In the rack

Details worth deciding before load-in.

  • Run both Dante Primary and Secondary ports to separate network switches on different VLANs — that redundancy is there for a reason, and a single switch failure should not kill anyone's ears mid-show.
  • Budget one antenna combiner port per ADTD channel, not per unit: two ADTD units means four combiner inputs, so spec your distro before you spec your transmitter count.
  • Label the four combo inputs at the rear with channel number and A/B source before rack build — Ch 1 In A and Ch 1 In B look identical under stage lighting, and a wrong patch during soundcheck is a hard problem to diagnose quickly.
  • Use Wireless Workbench's predictive RF scan before doors, not just at line check — Axient Digital's wideband capability only saves you if you have already moved frequencies away from interference before the audience walks in.
