Shure ADTD
Build a traceable monitor path from the console to an ADXR bodypack, checking audio input, radio configuration and remote control separately.

ADTD is the dual-radio Axient Digital PSM transmitter. Radio count is not a promise of available stereo mixes: expansion licenses, transmission mode and regional authorization govern the actual configuration.
Connections and required equipment
Console monitor sends enter the selected wired input; the transmitter routes them to a radio, then an antenna system sends them to the bodypack. ShowLink manages parameters without carrying the listening audio.
Prepare the system
- Record the band, firmware, active mode, licenses and approved antenna/combiner diagram.
- Select the intended input and channel assignment; confirm console and transmitter meters without clipping.
- Sync the intended receiver through the documented channel workflow, then rehearse at a controlled listening level.
Questions and troubleshooting
Case: Workbench sees ADTD, but its input meter is silent.
Device discovery confirms control connectivity only.
- Check selected analog/AES3/network input and source patch.
- For Dante, inspect subscriptions and clock status; compare Switched versus Split/Redundant port mapping before moving cables.
- If input metering returns after correcting source selection, the input stage is verified; continue through its radio assignment and intended bodypack. If control works but input stays absent, save source, port mode, clock and patch observations for Shure/network support rather than resetting the transmitter.
Case: IR completed, but the bodypack has no program.
Check which IR operation was performed.
- RX ShowLink Network ID Update copies the control network identifier; it does not sync audio settings or assign a receiver slot.
- Use the current channel receiver-sync instructions; verify frequency, mode, encryption and RF mute state.
- If channel sync establishes RF but the bodypack remains silent, compare transmitter input and receiver audio/output settings at reduced listening level. Verify the intended monitor mix with the performer before use; repeated sync errors require exact versions and messages for support.
Case: expected extra mixes or a mode are unavailable.
Compare actual licenses and installed firmware with the regional feature set.
- Do not substitute ADTQ radio counts or assume every mode permits the same expansion.
- Save the working preset and plan changes off show; recheck RF output power and coverage after expansion.
- If the requested combination is not enabled or permitted, revise the planned allocation with the system owner rather than changing licenses as a test. After a documented scheduled change, verify every required mix, RF coverage and listening level; unexplained resource differences require Shure support.
Choose the next check
| Observation | Next check | What to record |
|---|---|---|
| Control visible, no input | Source and network mapping | Patch and meter state |
| No program after IR | Operation and receiver link | Mode, frequency, sync result |
| Missing mixes | Licenses, firmware, region | Active preset and entitlement |
Precautions
- Use authorized frequencies and the exact approved RF accessory configuration.
- Protect listening levels before gain, mode or routing changes; do not copy another rig’s gain values.
- Do not change antenna combining or power distribution from a forum recipe.
