safe

#1

proof of effectiveness

99.99%*

The disinfection level of 99.99%* for surface disinfection inside Li.LAC has been approved by the independent, accredited laboratory Opsytec Dr. Gröbel GmbH.

The departments Biomedical Engineering and Medical Microbiology & Infection Prevention of the University Medical Center Groningen (UMCG) have conducted comprehensive scientific studies to evaluate the effectiveness of Li.LAC. Viruses were sprayed onto microphones**, similar to singing into the mic. The results show a reduction of 99.3% of the viral load on strongly contaminated microphones (including the metal grille and foam underneath) after 10 minutes irradiation inside Li.LAC.

* The exact disinfection level varies with the type of virus or bacteria and with the shape and the surface of the object to be disinfected.
** Industry standard vocal microphones were used for this study.

#2

microphone and material compatibility

tested

Any kind of intense cleaning procedure (soap & water, alcohol or UVC light) has a long-term effect on the materials used in or on microphones. Different kinds of plastics and the outer appearance (color / gloss) especially, can be altered or degraded by “too much cleaning”.

We have run numerous tests with various microphones inside Li.LAC to evaluate the long-time impact of UV-C light.

The results show that the aging effect implied by UV-C disinfection inside Li.LAC is negligible compared to the normal aging that happens to the microphones (by mechanical impacts, dirt, humidity etc.).

the professional approach

Li.LAC provides low impact, contactless cleaning and disinfection through ultraviolet light (UV-C).

Li.LAC has an intuitive control panel with colour display:

Violet = disinfection is running and UV-C lights are active
Green = disinfection completed
Red = error (chamber opened too early or UV-C lamp error)

Li.LAC is engineered and produced in Germany.

what our customers say

“When I first heard about Li.LAC, I thought: good idea, but will it survive on tour? Then I saw Li.LAC and I realized: this thing has to be on my tours!

Being a monitor engineer, I have always tried to supply clean and disinfected microphones to my clients. Before Li.LAC I was using sprays and wet wipes, both could harm the microphone. Also, you never knew if you really disinfected long enough or every spot on the mic.

With Li.LAC, I have a tested and clinically approved rack-unit for microphone disinfection, built for the rough life on the road.

I will spec Li.LAC for all upcoming tours worldwide.”

“We are currently in a state of a pandemic. Covid19 has all of us and especially the live music industry firmly under its control. Nevertheless, we are lucky to play some shows with “Jan Delay & Disko No.1“ on a national level during the summer of 2021. During the preparation it became clear quickly that many things would be different than the old “normal”. There are hygiene concepts, rules and special circumstances. We at 4LIVE Production thought about disinfection of microphones. What is the best way to do it? What options are there to accommodate this work step in the production process? And ultimately: what is the safest way? We are primarily talking about vocal microphones of guest singers for example who are different every day. And even if the same artist uses his or her microphone every evening, we still want to eliminate any possibility of infection.

After talking to LAC Labs, we were convinced by the concept of “disinfection through UV-C light”. The disinfection level, the material compatibility and ultimately, the speed at which we can disinfect microphones is exactly what we were looking for. In addition, Li.LAC is a product of German craftsmanship in a robust design and ready for the road.”

“I first tested Li.LAC at the beginning of the “festival season” 2021 and then bought it straight away, as the idea and, above all, the rugged and road-ready implementation of the device convinced me straight away.

When planning and implementing hygiene concepts, it is usually primarily about the audience, employees and the rooms in which they move. But the stage also offers some opportunities to improve certain processes in terms of hygiene. This is where Li.LAC comes into play.

Especially with multiple speakers, moderators and singers, as is common on festival stages for example, an intermediate disinfection of the microphones definitely makes sense. But Li.LAC is also used in everyday touring, when we can disinfect the microphones between the sound check and the start of the show.

The short disinfection time and the proven effectiveness complete the picture. From now on, Li.LAC will be an integral part of our tour gear.”

“Viruses, bacteria, aerosols, droplets – these words are on everyone’s lips, especially today. In order to optimally protect our artist Wincent Weiss while we are on tour and to minimize the risk of infections, we disinfect our microphones thoroughly and easily with Li.LAC.”

“… The health and well-being of my artists are paramount, more so in the current climate.

The Li.LAC unit provides fast, easy & safe disinfection of microphones, and is now an essential part of the Deep Purple touring arsenal. …”

“The recording of “Sing meinen Song”, which took place in the 8th season, was filmed in February 2021 in Germany under strict hygiene regulations. Due to these requirements, we also planned for the greatest possible safety in the audio department. Fortunately, Li.LAC was presented at the same time as our preparations, whereupon we immediately contacted LAC Labs. It was easy to rent a Li.LAC unit for the production period.

We used the Li.LAC device to regularly disinfect 8 handheld wireless microphones. We were convinced by the simple handling and the problem-free integration into the production workflow. We were able to hand over freshly disinfected microphones to the artists and recording managers at any time, without causing any delays. Disinfection with UV-C light also allows to adequately disinfect the close-meshed grille of the microphones, where disinfectants often leave behind moisture and odors. From our point of view, Li.LAC is a simple and useful tool to use – not only against COVID viruses, but also against cold bacteria, which hopefully will soon be our greatest concern again.”

“We chose Li.LAC because we were looking for a safe, convenient, and fast way to disinfect microphones.

Our Li.LAC is installed in a mobile rack so that we can use it in our concert halls as required.”

“… It was normal to share microphones. It was normal to pass a handheld mic from one singer to the next or to pass a mic through an audience for Q&A for example. Nobody, at least in my experience, cared about hygiene or found it necessary to clean the microphone grille. Then, now over a year ago, things changed. The world went into COVID lockdown and shut down live events. When we got the OK to reopen our small 300 seat theater (the Cube521 in Marnach, Luxembourg), we started to organize everything to keep the audience and artists safe. Masks, disinfectants for the hands and for the seats, signs, plexiglas dividers, etc.

But how to disinfect a microphone?
We started using Li.LAC, a rack-mount unit that can disinfect handheld microphones and headsets in detail and fast.
Usually after line check has finished, I place the microphones into Li.LAC for disinfection. This way we can provide clean, disinfected microphones to the artists at the beginning of the show or at the beginning of rehearsal.

Li.LAC is not only a great solution for the current COVID situation but also to kill all kind of viruses and bacteria that are always around.”

“audio-machinery is a technical service provider in the fields of broadcast, studio and live sound.

We had already invested in UV-C disinfection technology in June 2020. Now we are very pleased to finally have Li.LAC, a road-ready device that was specifically developed for our industry.

Thus, we have one less worry during transportation, and thanks to the extremely user-friendly operation, we can always have freshly disinfected microphones available for our customers. Especially the short duration of only 7 minutes (5min disinfection + 2min preheat) suits us very well in the hectic everyday TV studio life.
In the next days some equipment will leave our warehouse for a short tour, of course also including Li.LAC.

We are extremely convinced of the robust construction. These devices survive every use, no matter how harsh the conditions.
Thanks to the entire Li.LAC team for this great piece of equipment.”

“After my first experiences I can say that Li.LAC offers a great, intelligent, economical and reliable solution for microphone disinfection.

At this year’s general meeting of FC Schalke 04 in the Veltins Arena, multiple speakers were supposed to speak at the lectern, taking into account the current hygiene regulations.

A perfect occasion for the use of Li.LAC!

The proof of effectiveness ensured trust among the end customer and the speakers. The operation is more than simple.
Personally, I also appreciate the ecological factor.”
