Sound Signature: studio reference, full range with controlled 3D ambience

Drivers: single or dual, full-range balanced armature, no crossover

Using our patented, tour-proven Active Ambient technology, 3D AARO is the only in-ear system that delivers full, controlled room ambience with both earpieces in place. 3D AARO (which stands for Active Ambient, Record Out) gives musicians their ears back.

The system consists of custom-fit soft silicone earphones with embedded binaural microphones to capture ambient sound with full 3D directionality. The ambience is routed to the compact bodypack mixer, where it is combined with the monitor mix and delivered to the ears with zero latency.

A convenient toggle allows instant switching between Perform Mode (used while playing) and Full Ambient Mode (for communication between songs). Internal controls include ambience volume control, Bass Boost, and Limiter. A stereo Microphones Out plug provides full access to the binaural ambience signal for recording.

3D AARO is the only in ear monitor system offering controlled ambience with 3D directionality, isolation from extreme volume, reference monitor response and the comfort of custom silicone earpieces. No other company has anything close.

"With radiohead, the 3d was totally the right way to go. the ambient soundstage is very natural sounding, and the band loved the system from the get-go.

"The great thing about the 3D is that is eliminates that 'I feel closed in' objection to in-ears. You feel closed in? Just turn up the ambience knob. Even one click changes the whole ballgame. Powerful stuff. With Radiohead, everyone was extremely happy with the 3D. On the whole tour, there were literally no complaints - I mean zero!”
