A Meeting of Pro Sound Industry Icons

Jerry Harvey and Christian Heil can both lay claim to pioneering technologies that would change the pro audio industry forever.

Harvey, an accomplished monitor engineer, first developed a custom in-ear monitor (IEM) for drummer Alex Van Halen in the 90s. As the band toured, word traveled and Harvey would devote his career to defining the state of the art for multi-driver in-ear monitoring. From the Grammys to the VMAs to the Superbowl halftime show to major tours, Harvey’s innovations can be seen in the ears of artists including Aerosmith, Lady Gaga, Guns N’ Roses, Miley Cyrus, Drake, Katy Perry, Justin Bieber, Camilia Cabello and many more.

Heil, the founder of LAcoustics, is credited with inventing the line source array, the loudspeaker technology that serves the live events industry to this day, and the benchmark for artists in more than half of the top grossing festivals and at the biggest music festivals around the world.

Contour XO is born of the meeting of these two pro audio industry icons. Harvey and Heil have combined the forces of their R&D teams to co-engineer the renowned L‑Acoustics sonic signature in a premium IEM that continues to elevate the standard for in-ear monitoring.

Contour XO for LISA Mixing

The success of LISA Immersive Hyperreal Sound technology and spatialized mixing tools has led LAcoustics to seek ways to further streamline the production process. Contour XO is the latest addition to the LISA engineer toolkit and a natural complement to LISA binaural software tools that will be released in early 2021.

A preview of this exciting new software is now offered to first adopters of Contour XO. Upon ordering, you will receive a software activation key.

What has always drawn me to LAcoustics is its musicality: solid sub, punchy low end, thick but detailed low mids, balanced midrange, aggressive yet controlled high mids and, most impressively, smooth and realistic high end. Too many systems nowadays go for unnatural, overhyped high frequencies. Not LAcoustics. Simply put, it sounds like music.

LAcoustics has provided us with many great tools to enhance what we do. Having the same characteristics in an IEM is a game changer! With Contour XO, the collaboration between LAcoustics and JH Audio may be the turning point – the next generation of IEMs.

My goal as a systems engineer is to create a blank canvas for the mix engineer to paint on so that every day the painting sounds the same. I’ve always felt that LAcoustics products have the sonic transparency and fidelity to streamline this procedure because they start the optimization process on the mechanical level.

Arica Rust

Systems Engineer

At this year’s BRIT Awards at London’s O2 Arena, I was mixing front of house for UK artist Stormzy. I was so impressed with the audio quality and dynamic range, especially the low-end extension. The clarity and phase coherency was like mixing in the studio, yet the front of house mix position was way back in the room. The bass was intense all the way to the cheap seats, in a word: colossal!

Wayne “Rabbit” Sargeant

Studio and live mixing engineer

From a professional end-user perspective, I think the Contour XO are going to be perfect for live mixing reference as well as portable mixing rigs, especially if you are used to mixing an LAcoustics system. In addition, I think musicians and vocalists who want an idea of how the room is sounding in their ears will find this new product very appealing.

Jack Nellis

Studio and live mix engineer for Elevation Worship

As the FOH engineer for Outkast on an extensive world tour I had the chance to test all the top PA systems and was totally blown away by the LAcoustics K1 system. In 2017 as FOH for Logic I had the opportunity to build my all-time favorite PA: LAcoustics K1 over K2, with my favorite sub the KS28, with 2 Kara on top. I got everything I was looking for out of that PA. It was pristine and crystal clear for my application of 128 dB, in-your-face hip hop! I can’t wait to hear the next generation of audio from LAcoustics.

Darcy Khan

Front of House engineer for Outkast, Kanye West, Logic and Drake

I cannot forget the moment that I listened to LAcoustics technology for the first time in 1997. The LAcoustics system was and remains incomparable and was the game-changer in the Korean pro audio industry. The sound of LAcoustics is the reference for live shows. Contour XO is exciting news for audio lovers and especially fans of live music. I believe the IEMs will bring that huge live sound, and the feeling that comes with it, into the home.

Kim Do Seok

Mixing engineer of K-pop

When working on one of our EDM festival sound designs for a client, you show the best and most optimized solution with a detailed view of the project. It is our job to provide a PA that will meet this solution with a similar sonic footprint throughout the whole family tree as well as provide the client and most of all audience with an exciting sonic experience. For those reasons L‑Acoustics has been the system of choice

Arno Voortman

System engineer and sound designer

There’s something immeasurable about LAcoustics speakers. When I mix on a K1 or K2 system it somehow puts me “inside” the music. Sonic details emerge, music blends together easily, and my mixes seem to have more depth and dimension. It becomes a sonic experience that no other technology can deliver.

Lance Reynolds

Front of House engineer alt-J

The end of a tour always comes, and while relaxing in the comfort of home, I had always pondered being able to have that LAcoustics sound on the couch. With the recent development of the Contour XO IEMs, we have the opportunity to take that LAcoustics sonic signature anywhere. I also look forward to having the option of using Contour XO when it’s time to get back on the road.
