ASI Audio

The ASI Audio 3DME.
Hear incredible.

With the ASI Audio 3DME, you can enhance, control, and fine tune true 3D ambient audio into a personal monitor mix in any live environment.

Enhances sound

Embedded binaural mics capture full frequency and dynamic natural ambience with accurate 3D directionality. Full-range drivers give reference-quality sound without crossover distortion.

Enhances hearing health

Rapid sound limiting keeps your 3DMEs at healthy sound levels and three sizes of zero-fatigue eartips ensure a tight seal to reduce harmful stage loudness.
Custom molded eartips are available, too.

Enhances control

The ASI Audio app lets you create custom settings for each ear, with EQ and the levels of room ambience for an individualized monitor mix. Fine tune your mix during rehearsal or soundcheck, then go play!

Embedded binaural mics, a bodypack, the app, and an audiologist's magic.

3D active-ambient technology was conceived by renowned audiologist Dr. Michael Santucci of Sensaphonics for its legendary 3D AARO IEMs, used by touring pros around the world. The magic comes from tiny embedded binaural mics that bring room ambience to your monitor mix as a discrete signal while enhancing sound quality and protecting from excessive sound levels. Now this same technology is available in the new 3DME system controlled by the ASI Audio app.

Plays well with others.

The 3DME is particularly effective in acoustic and orchestral performance environments as well as amplified setups. The ASI Audio app lets you personally tune the amount of audio enhancement, levels, ambience, and equalization. Set it during rehearsal to the sound of the hall, then leave your phone or tablet behind.
