Detail 01
Omnidirectional pickup
Level stays even as the talker turns their head. It also hears the room, so keep monitors down.

Audio-TechnicaAT803 Omnidirectional Condenser Lavalier Microphone
1/3
Independent shopping perspective
The Korena take
Omnidirectional condenser lavalier for speech — lectures, theater, broadcast. Runs on a AA battery or phantom power and feeds a wired XLR input.
Strong match
Who this is for
- Lectures, panels and interviews within reach of a wired input
- Theater body mics where head turns must not change level
- Video and broadcast work needing a capsule that hides easily
Consider the trade-offs
When to look elsewhere
- Loud sources — headroom stops at 106 dB SPL on phantom
- Live rigs needing pattern rejection for gain before feedback
- Anyone who wants a replaceable cable; it's permanently attached
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
6 ft cable, permanently attached, TA3F end
A damaged cable means a new mic. Six feet reaches a belt-worn module, not a distant mixer.
Detail 03
Battery or 11-52V phantom
Phantom lifts max level from 92 dB to 106 dB SPL. Use it wherever anyone gets loud.
Detail 04
80 Hz roll-off, 18 dB per octave
Steep cut for HVAC rumble and chest thump when the capsule sits on the sternum.
Detail 05
72 dB signal-to-noise
Fine for normal speech at chest distance. Very soft talkers will push your preamp and reveal hiss.
Detail 06
2.5 g capsule, 20.5 mm long, 10 mm wide
Light enough to tape under clothing or hide at a hairline without dragging the fabric down.
Final check
Know before you order
- 01Clothing clip, windscreen, AT8531 power module, battery and carrying case are included
- 02You still supply the XLR cable from the power module to your mixer
- 03One AA runs about 1200 hours; phantom power skips batteries entirely
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does it need phantom power?
No. It runs on one AA in the included AT8531 module, or on 11-52V phantom. Phantom buys headroom: 106 dB SPL instead of 92 dB.
02Can I use it with a wireless bodypack?
The cable is permanently attached and ends in a TA3F connector that mates with the included power module. Check any bodypack for that connector before planning on it.
03Will it pick up other people in the room?
Yes. Omnidirectional means it takes in the whole room fairly evenly. Chest placement and low monitor levels matter more than aiming it.
04Can I replace the cable if it fails?
No. The cable is permanently attached to the capsule, so cable damage means a new microphone. Route it carefully and add strain relief at the clip.
