L-Acoustics L2 Hands-On & Huge Festival PA

Dave Rat provides a rundown on the L-Acoustics L2 system, comparing it to the K2 system and noting that it is smaller in height but outputs the same level of sound with less low-end than the K2. The L2 has adjustable panaflex coverage and wiring diagrams with 20 speakers. The L2's amplifier outputs roughly 1200-1300 watts per channel and has separate DSP. Dave Rat also introduces a laser sight unit used for determining the fly bar angle and monitoring the site angles of all the arrays in the system. Additionally, the L2 bump and bar's load rating and use in dead hang angles are discussed, along with the rotator feature for single point hanging and array rotation. The L2 system is 100-350 pounds lighter than the K2 system and offers more control.

I was there at Stagecoach in one of the tents- I was FOH for one of the artists performing. I recognized these boxes right away and was really impressed with the whole system. Thanks for making my job easy- you and your crew as always were top notch! Cheers.

Thanks so much Dave. Most of us who do non-pro sound will never get to see a system like this from your point of view, and for me it seemed like arcane knowledge. Your openness and enthusiasm to share and demystify how this all works is very generous, but has the additional benefit of sharing what super high end systems look like, and are capable of as a reference when looking at lower price points. I love this so much! I can't tell you how many times I've been at a show as a punter and couldn't make out what the line arrays were and how they were configured - it drives me nuts 😁

I follow you for almost more than 10 years Dave and i just wanted to thank you for priceless informations, vision, new ideas and the all kinda stuff how to do. Your'e an industry standart for me :D Greetings from Turkey! 💙

[artysanmobile]

I am wowed by these superbly designed products. These are not incremental changes, more like a revolution. We can take advantage of what for all intents and purposes are ready made solutions to the thorniest issues. L-Acoustics is a brave bunch of people to invest so much in research and tooling to produce these significant advances.

[chrishuskinson]

I've followed you for years. Your genius still amazes me :) Complex shows and great ideas for design etc Keep doing what you do, the world of sound is a much better place With a Dave Rat in it Love from the UK :)

Very inspiring, and simply awe to see high end in it's present. Tyvm.

[matteup]

I'm glad it's not hidden. Being able to see those beautiful speaker arrays is PA-Porn for me! 😍

[vittoriocerroni]

Hi dave i am getting in the work now, working with d&B t10 so much smaller PA
Thanks for sharing all this information! i always whatch the videos and dont skip a second. Can find noone else who puts passion and dedication like you do in informing us beginners about the newest possibilities (but also the basics such as x32 videos) . THANKS A LOT!!! I would really like to meet you one day. Greetings from Italy, sherwood festival second stage ❤

[fitton]

🤣 Dog eating ice cream bar!! You're a gem Dave!! Thanks for sharing! Very cool setup!

[MichaelNatrin]

Fantastic rundown of the innovative and world-class Coachella setup. Thanks for sharing this. Please feature more videos of Bones eating things.

[jonkilowatt]

Dave, I’m always enjoying your videos! Your genius blows me away with these designs! Awesome !!!

[cameronclarkhull]

Was at Eurovision 2023 in Liverpool. Tbey had several L2s arrays on the side of the arena. Wad really impressed with how they sounded.
Hope sound designers for UK musicals invest in these 🙂

[rowanjones]

Love this format of video Dave, especially your thinking regarding flying the PA above the video screens. No doubt we'll be seeing this concept copied elsewhere.

[Edwin-van-der-Putten]

Cool video, Dave! Thanks for the hard work! 🙂

[shaunfernando]

Hey, i came from the wired video. I had to instantly subscribe because that was really good and interesting. Can't believe there is already some updates to the line array since the wired video

[Sachifu]

I really like how your passion and zeal for the art of sound system design comes through in these videos. It's really inspiring, wish I could take my EE degree and find a way to support your team.

I guess, with integrated cardioid, these boxes will be able to compete with the new D&B KSL boxes that seem to be gaining popularity (though I think L-acoustics still seem to be used at the majority of events.) If they ever release an L1 rig that can compete with the larger K1 and D&B GSL in volume, that would probably change the game. I recently went to an arena concert (Missy Elliott) that used entirely D&B KSL arrays. The entrance to the arena was behind the stage, and I couldn’t hear ANYTHING from there. In previous concerts in the same arena with K1/K2, Meyer Leo, and Clair Global Cohesion arrays, I could certainly hear them upon entrance. I can’t wait to hear L2 in action at an event some time.

[johnmcquay]

I finally got to see the L2 at Plasa yesterday; it really is a beautiful product. I'm really looking forward to hearing it.

I'm on the east coast so I haven't seen the festival first hand. I worked for a sound company locally that went beyond regional so yes we would fly things and had the rigging crew on the high wire. The 2 brother's that had the company tried to stay domestically to our state and used Community Loudspeakers. BUT I am dated as this is over 20 years BUT huge huge video screens which is a great presentation for the size of the real estate there & the lay of the land there. That is a massive array of speakers considering the size of the drivers....to get air moving. If you recall in a different post from bounce you are talking about....I made the statement of the baseball pitcher and the distance relationship to the that was on electron much the same way...its the distance and the development of the wave. pebble being dropped in the center of a perfect circle pond of size...so the focal point of ground zero when the pebble disturbs the water surface and the resulting waves picking the distance from ground zero for the maturity of the wave and where to "sample" and playing goldie-locks for just what an array of air pumps to a wide open opposed to a classic greek amphitheatre....or the lay of the land in a bowl or valley. COOL !!

Your test tone at the end bothered my dog. LOL! Also showed me where I need to tweak my room acoustics, so thanks! :-D

This Coachella rig looks like it had to have been a blast to design and deploy! Plus the opportunity to work with that cutting-edge new L2 system!
