IEM Rack for Mac
IEM Rack monitors and controls Audio-Technica 3000 Series in-ear monitor transmitters (ATW-T3205) from a Mac, and can send frequencies from Shure Wireless Workbench exports. It requires macOS 11 or later on Apple silicon.
- Transmitters not showing up? Make sure the Mac and the transmitters are on the same network and subnet, and that each transmitter has a reachable IP address.
- Need to use A-T Wireless Manager? Turn on Pause control in IEM Rack's Settings to release its connections, then turn it off when you're done.
- After a frequency push, RX SYNC each bodypack so it matches its transmitter.
- Want to try it without hardware? Use the built-in Demo rack.
For IEM Rack questions or bug reports, email zach@kernstechsolutions.com with your macOS version, the app version (IEM Rack menu, About), and your transmitter model and firmware.
Frequently asked questions
What areas do you serve?
We are based in Ankeny, Iowa, and regularly work across the Des Moines metro and central Iowa. Church plant packages and consulting can be provided outside Iowa as well. Just ask.
What is a church plant tech package?
A complete, portable audio, video, and lighting system designed for a new church meeting in a rented space. It is packed in road cases so volunteers can set up and tear down quickly every week, and it comes with labeling, documentation, and training.
Do you only work with churches?
Churches are our specialty, but we also help schools, nonprofits, and small businesses with AV systems, networks, and IT setup.
Can you work with equipment we already own?
Yes. We will evaluate what you have, reuse what still serves you well, and recommend upgrades only where they make a real difference.
Do you offer training for volunteers?
Every install includes hands-on training, and we can schedule follow-up sessions as your team grows or changes.
How do I delete my data from an app?
IEM Rack has no accounts and stores everything on your Mac. To remove its data, quit the app and delete the "IEM Rack" folders in ~/Documents and ~/Library/Application Support. For any other app of ours that has an account, email zach@kernstechsolutions.com and we will delete your account and related data within 30 days. See our Privacy Policy.
