Detail 01
Power module only
This is the box the mic feeds into. Swapping it does not change how a capsule sounds.

Audio-TechnicaAT8539 Power Module
Independent shopping perspective
The Korena take
The powering module for an Audio-Technica lavalier setup, not a microphone. Buy it as a replacement or spare for a rig you already own.
Strong match
Who this is for
- Replacing a lost or damaged module on an existing AT lav
- Keeping a spare so one dead module never kills a channel
- Adding a second channel to a mic you already have
Consider the trade-offs
When to look elsewhere
- Anyone shopping for a microphone — there is no capsule here
- Buyers who haven't confirmed which module their mic model takes
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Audio-Technica system part
Module and mic model numbers are matched pairs. Don't assume AT parts interchange across mic families.
Detail 03
One module, one mic
A two-person interview setup needs two modules, two capsules and two inputs at the mixer.
Detail 04
$139 for a component
Close to what a complete entry-level lav rig costs, so weigh repair against replacing the whole setup.
Final check
Know before you order
- 01Match your mic's model number to the module before ordering; AT parts aren't universal
- 02Sold as the module itself — capsule, clip and windscreen are separate
- 03Confirm your mixer input can supply whatever the module expects
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this a microphone?
No. It's the powering module that a lavalier element plugs into before the signal reaches your mixer. You supply the mic.
02Will it work with any lavalier mic?
Only with the Audio-Technica mics it was built for. Check your mic's model number against the module rather than assuming it fits.
03Do I need one per microphone?
Yes. Each mic needs its own module, so a two-person setup means buying two.
04Does anything come with it?
Treat it as the module alone. If you need a capsule, clip or windscreen, order those separately.
