The Engage Live features a dual driver, 2-way crossover configuration delivering deep, engaging low end, well defined midrange and smooth detailed highs with no harmonic distortion. To make things even better we have now introduced our exclusive SSI technology to the Engage.

Our redesigned cable and mounting system ensures excellent durability and gives the Emotion a great look.

Continuous Development

We have introduced our patent pending IRIS and exclusive SSI technology across our entire IEM line-up.

IRISIntelligent Resonance in Silicone is a patent pending technology we have created to maximise the potential of miniature balanced armature speakers. IRIS construction methods allow for very precise acoustic tuning to deliver our unique ACS sound signature. IRIS brings an added dimension to music in a way that mimics the warm, lush and open sound that valve amplifiers provide.
SSISound Stage Imaging is a tuning technique achieved by using our own purpose designed manifold technology. Implemented into our custom and universal in-earphones, SSI positions the audio into a wider array than other earphones, bringing a superbly defined and very detailed response to further enhance your listening experience, positioning all the instruments as if you were sitting in front of the stage listening to the live performance.

Maximise your IEM experience

Every ACS Emotion Live! has a pair of built-in, wideband, natural response microphones! Interfacing our new Ambient Live! Pack between a wireless belt pack or mixer, your Live! In-ear monitors will allow you to introduce and adjust your ambient surroundings independently from the mix. This gives you the ability to control the outside sound and safely eliminate the isolation experienced by wearing good sealing in-ear monitors. The full 3D effect of the ambient signal perfectly mimics your natural hearing, giving you great positional ambient cues and is much more effective than stage pick-up mics which must be controlled at the desk and do not give a sense of depth or position. All of this is seamlessly taken care of by the intelligent DSP system integrated into the Ambient Live! Pack with great clarity and ultra-low latency.

So, if you're ready to take your IEM experience to the next level you can view the Ambient Live! Pack on our website and download the specification sheet and snap up one of our new Ambient Live! Packs and start enjoying the benefits of going Live!

Final Word

Combining the latest ACS technologies and the Live! system Engage delivers a great value all rounder, warm, detailed and highly enjoyable IEM. If you are looking for an IEM which really Engages you and you want the option of Live Ambient sound then the ACS Engage is the one for you.

A few words about care and maintenance

We make our in ear monitors with pride and like all things worth having, they are worth looking after. Just follow these simple rules and you should receive many years of trouble-free service.

  • Check the sound ducts after each use and use the wire pick supplied to remove any ear wax that has made its way into the tubing.
  • Never use the cables to remove the IEMs - this will eventually put strain on the connector and will damage the cable.
  • Ensure moisture from either humidity or sweat is removed straight after use. We supply silica gel and a zip up pouch for this purpose. We recommend using your Revivo dehumidifier after each use.
  • Finally, read the instructions supplied.
