The ultimate in-ear monitor for professionals onstage or in the studio. The A12t does it all, delivering detailed highs, distinguished upper and lower mid-range detail, a clean bass response, and strong sub-bass. Offering reference-level detail, this IEM is among the best for multi-instrumentalists, engineers, sound monitors, and audiophiles.
This model is also available as a Universal IEM, the U12t.
Exclusive technologies that challenge traditional in-ear monitor designs to give you the absolute best listening experience
A12t features the following unique technology:
Air Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations available for A12t: mX, m15 and m20.
Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 12 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.
Tubeless In-Ear Audio (tia) is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. A12t features two major elements of the tia system: the tia driver and the tia single-bore design.
3D-Fit preserves the detail of your ear impressions using a new process of digital rendering and 3D-printing. The patented process of incorporating acoustical tuning features within an IEM’s shell allows for designs that would otherwise be impossible to build using traditional methods. We incorporate these advanced and uniquely complex features into the shell in order to manipulate the audio produced by the IEM. This process also reduces distortion in the impression for the most precise and comfortable custom in-ear monitors available.
