1/8On the road to success with Sennheiser: Aventem expands its wireless technology withthe addition of 72 digital EW-DX wireless channels

Wedemark/Hilden, August 2024 – Aventem is a renowned event technology service
provider based in Hilden near Düsseldorf. Founded in 2006, the production company
specialises in corporate events of all types and sizes and supports customers fromvarious industries throughout Europe. When it comes to wireless audio transmission,
Aventem has always relied on premium products from Sennheiser. In June 2024, thecompany significantly expanded its already extensive inventory of wireless equipment –and it chose Sennheiser’s groundbreaking EW-DX systems to do the job.

Huge investment in Sennheiser EW-DX
The company purchased 18 Sennheiser EW-DX EM 4 DANTE four-channel receivers, 72 EW-DX
SK bodypack transmitters and 72 EW-DX SKM handheld transmitters, fitted with MMK 965-1
true condenser microphone capsules. The systems are operated with passive Sennheiser ADPPRESS RELEASE

UHF directional antennas (470 to 1075 MHz) and can be remotely monitored and controlledusing the Sennheiser Control Cockpit, the Sennheiser Wireless Systems Manager (WSM) or –for smaller systems – the Sennheiser Smart Assist App. The four-channel 19” receivers (1 RU)
have integrated power supply units and, at Aventem, are connected digitally via their Danteinterfaces to the audio mixing consoles, which are also digital.

Twelve hours of battery life, a switching bandwidth of up to 88 MHz (Standard Mode with
600 kHz spacing for up to 146 channels, Link Density Mode with 300 kHz spacing for up to293 channels) and, of course, intermodulation-free signal transmission with outstanding audio
quality are just some of the features that are particularly appreciated by the technicians at
Aventem. Another very useful feature is the integrated antenna splitter with antenna poweringand loop-through to daisy chain up to 16 channels (4 x EW-DX EM 4). Thanks to the proprietary
Sennheiser Performance Audio Codec (SePAC), latency in the EW-DX is just 1.9 ms and is not
perceivable in practical operation. The EW-DX series transmitters with their stacked A/Dconverters do not require any adjustment of the input sensitivity.

Alongside the new EW-DX systems, Aventem has 16 digital Sennheiser EM 6000 two-channel
receivers available, as well as 32 SK 6000 bodypack transmitters and 32 SKM 6000 handheld
transmitters with MMK 965-1 microphone capsules. Wireless in-ear monitoring is based on
analogue wireless technology from Sennheiser’s 2000 series.

Sennheiser EK 1039 Tourguide receivers are also part of the inventory, as are wired
microphones from the Sennheiser and Neumann portfolios, including eight Neumann Miniature
Clip Mic systems with KK 14 capsules.

Sennheiser and Aventem: a close partnership“Our partnership with Sennheiser goes back a long way,” says Holger Niewind, Managing
Director of Aventem. “In addition to the undisputed high quality of the products and theirproverbial reliability, we particularly value the short communication channels that we havewith a German manufacturer. Sennheiser’s Jörg Langel has been our direct contact partner for
many years, he’s always ready to listen to our concerns and ideas.”

Holger Niewind, Co-Managing Director of Aventem

Niewind continues: “Analogue wireless channels from Sennheiser have been our faithfulcompanions for many years, but nowadays digital wireless systems with their high spectral
efficiency are the tools of choice. We have been regularly using Sennheiser Digital 6000
systems at events since 2018, and our technicians always speak highly of the fact that they
can arrange the transmission frequencies in an equidistant grid. This saves a huge amount oftime when setting up the frequencies and generally minimises the stress involved withwireless systems, which is of course a tremendous advantage at events. Another usefulfeature of the digital Sennheiser channels is the secure transmission of confidential content
using AES 256 encryption – many industrial customers, and especially customers from thefinancial sector, definitely appreciate this possibility.”PRESS RELEASE

Hendrik Coers, also Managing Director of Aventem, adds: “With the purchase of the newSennheiser EW-DX systems, we have significantly expanded our inventory of digital wirelesschannels – as far as I know, we are one of the first event technology service providers inGermany to have done this on such a scale. We have always had the best experience withSennheiser products over the years, and our investment in EW-DX shows that we are reallysatisfied.”

Hendrik Coers, Co-Managing Director of Aventem

Aventem: a production company with passion and expertise for every event
As well as its headquarters in Hilden, Aventem GmbH Audiovisual Services has a branch inBerlin. “We are truly passionate about this company”, says Holger Niewind, with Hendrik Coers
adding: “Whether it’s a small conference, a corporate event or a large public event, we doabsolutely everything we can to make each and every project a success.” The two managing
directors, who worked together in the same company before Aventem was founded, are clear
about their mission: “We are a production company and not an equipment rental firm. We
implement projects from start to finish, and our aim is to create the best possible result fromthe perfectly coordinated interaction between technology and set design – to the complete
satisfaction of our customers.”

Trucks at the storage andproduction area

One of Holger Niewind’s personal project highlights was the celebrations to mark the 125thanniversary of the company RWE, which was attended by more than 11,000 employees of theenergy group at the Messe Essen exhibition centre in October 2023. Aventem was responsible
for the entire technical infrastructure at this major event, which was spread across several
exhibition halls and even included a concert by star guest Robbie Williams. At the same time in
Stuttgart, the Landesbank Baden-Württemberg held its employee party in the Hanns-MartinSchleyer-Halle, the Porsche Arena and various adjacent locations. More than 8,000 guests
were invited and were able to enjoy rousing performances by Milky Chance and Jan Delay.
Here, too, Aventem was responsible for the complete technical implementation as the sole
service provider.

Growth with a sense of proportion
In 2017, Aventem moved into a newly built company location with over 6,500 m² of storage andproduction space on a plot of almost 12,000 m². Spacious shared and individual offices, stateof-the-art production suites, attractively designed recreational areas and, not least, amenities
such as a billiard table and even a beach volleyball court contribute to the pleasant working
atmosphere in Hilden.

“We have grown significantly in recent years and Aventem now has well over 60 permanent
employees,” says Managing Director Holger Niewind when asked about the company’s
immediate future. “I think we’ve reached a pretty good size. We don’t necessarily want to go
on growing fast at all costs – instead, we are currently working on further optimizing ourprocesses. We will continue to focus on the industrial customer segment in the future. We
have no plans to expand into the touring sector or to increase dry-hire activities.”

The entrance to one of thecompany’s own production
suitesDuring the Covid pandemic, Aventem was quick to develop strategies that enabled them tomeet the special challenges of what was an extremely difficult time for the entire industry. For
example, in March 2020, they put their first streaming studio into operation at the Hilden site.
Today, up to seven of the company’s facilities are used for streaming purposes, supplemented
by external locations. “We quite quickly found a workaround that we were happy with,” says
Holger Niewind. “Fortunately, everything has now returned to a normal level, although weclearly noticed the catch-up effects, especially last year. We were pretty much overwhelmedwith work in 2023!”

Training future specialists
Aventem places great emphasis on a practice-oriented training. Currently at Aventem, nine
young people are preparing for their future by studying for qualifications in event technology,
office communication management and event management.

Focus on sustainability
In recent years, Aventem has invested heavily in stage construction and set building and has
significantly expanded the company’s own workshop for this purpose. Design elements suchas movable platforms, kinetic installations or 3D mapping areas for elaborate stage
productions are produced individually according to customer requirements. The focus isincreasingly on using sustainable materials such as wood from certified forests. “This is very
important to us, and our customers are also placing more and more emphasis onenvironmental aspects – people now have a different awareness than before,” says Sebastian
Rudolph, Director Marketing & Sales at Aventem.

Sebastian Rudolph, Director
Marketing & Sales at AventemSustainability forms an integral part of Aventem’s corporate philosophy, and for that reason
the production company focuses on implementing environmentally friendly mobility andenergy solutions. A large solar power system on the roof of the headquarters is not only used
to charge the company’s fleet of electric vehicles, but also generates electricity to meet theneeds of the Hilden site. “We can also use this solar power to recharge some of our equipment,such as battery-powered spotlights,” Sebastian Rudolph points out. “Of course, the same
applies to our Sennheiser LSP 500 PRO wireless loudspeakers, which are equipped with EM
300-500 G4 wireless receivers and SR 300 IEM G3 stereo transmitters. A lot of small steps likethese go together to make a big difference, and that includes the fact that our new EW-DX EMPRESS RELEASE

4 DANTE receivers fit four channels into one rack unit, which means that transporting themrequires half as much space as two-channel receivers.”
