Groh P.A. Veranstaltungstechnik, a prominent provider of professional event technology services, has announced a significant expansion of its rental inventory through a substantial investment in Riedel Communications’ industry-leading intercom solutions. This strategic move incorporates a wide array of high-end equipment, including Bolero wireless systems, Artist-1024 matrix frames, and the latest generation of Smartpanels. By integrating these technologies, the Buchholz-based company aims to address the escalating demand for robust, scalable, and fail-safe communication infrastructures across the full spectrum of live events, from intimate corporate gatherings to sprawling international festivals.
The cornerstone of this investment is the Riedel Bolero wireless intercom system, which has become a de facto global standard for high-stakes production environments. Groh P.A. has procured a versatile mix of hardware, including standard Bolero Beltpacks and the newer, more compact Bolero Mini Beltpacks. This hardware is supported by an extensive network of Bolero antennas, which offer flexible configuration options through Standalone and Pro-App licenses. To ensure a complete user experience, the acquisition includes specialized MAX-D1 and MAX-D2 headsets, as well as high-capacity charging solutions designed for the rigors of touring and rapid-turnaround events.
The Technical Evolution of Event Communication
The transition to Riedel’s ecosystem represents more than a simple equipment upgrade; it signifies a shift toward IP-based, decentralized communication architectures. In the modern event landscape, the complexity of production cues—involving lighting, video, pyrotechnics, and broadcast elements—requires a communication backbone that is both instantaneous and crystal clear.
The Bolero system utilizes Advanced DECT Receiver (ADR) technology, a proprietary solution from Riedel that significantly improves radio frequency (RF) robustness. By utilizing a diversity receiver technology that reduces sensitivity to multipath reflections, Bolero ensures that signals remain stable even in environments with high levels of metallic interference or dense physical obstructions. For Groh P.A., this reliability is a critical selling point, particularly for productions where radio frequency congestion is a constant challenge.
Jan Grohmann-Falke, owner of Groh P.A. Veranstaltungstechnik, emphasized the strategic importance of this infrastructure. According to Grohmann-Falke, the success of a production is often decided by the quality of its underlying infrastructure. He noted that reliable communication serves as the nervous system of any event. By investing in Riedel, the company is positioning itself as a premier partner for both internal full-service projects and external dry-hire clients who require equipment that is universally recognized and trusted by freelance engineers worldwide.
Integrating the Artist-1024 Matrix and Smartpanels
For large-scale applications requiring complex routing and high port density, Groh P.A. has integrated multiple Artist-1024 frames into its fleet. The Artist-1024 represents the pinnacle of Riedel’s matrix technology, offering a software-defined hardware platform that supports up to 1024 non-blocking ports in just two rack units. This system is designed specifically with an IP-native core, utilizing SMPTE 2110-30/31 (AES67) connectivity to allow for seamless integration into modern broadcast and live sound networks.
To interface with these frames, Groh P.A. has selected Smartpanels from the 1200 and 2300 series. These panels are not merely intercom stations; they are multifunctional user interfaces that can be customized to trigger various logic functions, monitor audio feeds, and manage complex talkback groups. The inclusion of SFP (Small Form-factor Pluggable) modules for AES67 and Dante ensures that the communication system can "talk" to almost any other piece of digital equipment on the network, facilitating a unified workflow across different technical departments.
Fynn Heidutzek, Lighting Project Manager at Groh P.A., highlighted the operational efficiency gained from the new setup. He pointed out that the Bolero system can be deployed within minutes, providing immediate stability in difficult RF environments. In high-pressure scenarios where riggers, operators, and directors must maintain constant contact, the superior audio intelligibility of the Riedel system becomes a decisive factor in maintaining production safety and precision.
Bridging the Gap: NSA Interfaces and Analog Integration
Recognizing that many venues and existing setups still rely on legacy hardware, Groh P.A. has also invested in a range of interface solutions to ensure total interoperability. This includes the NSA-series interface boxes (specifically NSA-002A through NSA-008A), which allow for the conversion of analog audio signals into the digital AES67 environment.
Furthermore, the addition of the Riface DM4400 allows for the seamless coupling of digital and analog radio systems. This is particularly relevant for large-scale security operations or logistics teams who may be using traditional walkie-talkies. By bridging these two worlds, Groh P.A. can offer a unified communication platform where a director on a Bolero beltpack can communicate directly with a security guard on a standard UHF radio, ensuring that no department is left in an information silo.
"DryHire plus" and Market Positioning
A key component of Groh P.A.’s market strategy is the introduction of the "DryHire plus" service model. While traditional dry-hire involves the simple rental of equipment, "DryHire plus" provides clients with a higher tier of technical support. This includes expert pre-configuration of the Riedel matrices and Bolero networks before they leave the warehouse, ensuring that the gear arrives on-site ready for immediate deployment.
This service is particularly valuable for smaller production companies that may not have in-house Riedel-certified technicians but want to offer their clients the highest standard of communication technology. By providing the hardware alongside specialized technical knowledge, Groh P.A. is effectively lowering the barrier to entry for sophisticated intercom systems in the German event market.
Chronology of the Investment and Industry Context
The decision to expand the Riedel portfolio comes at a time when the event industry is experiencing a significant technological "arms race." Following the global hiatus in live events between 2020 and 2022, the industry saw a rapid return to large-scale gatherings, but with a renewed focus on digital integration and remote production capabilities.
Groh P.A.’s investment timeline reflects a multi-year strategy to modernize its entire inventory. By mid-2026, the company has successfully transitioned its primary communication stock to IP-based systems. This move aligns with broader industry trends where traditional analog copper-based systems are being phased out in favor of fiber-optic and Ethernet-based backbones.
The broader implications for the Northern German event market are significant. As one of the major players in the region, Groh P.A.’s adoption of the Artist and Bolero platforms sets a benchmark for local competitors. It also strengthens the rental pool for international tours passing through Germany, which often rely on local partners to provide compatible Riedel hardware to supplement their touring kits.
Looking Ahead: LEAT con 26 and Future Growth
The industry will have its first major opportunity to see Groh P.A.’s expanded portfolio in action at the upcoming LEAT con 26, scheduled for October 6–8, 2026, in Hamburg. Groh Distribution, the sister company to Groh P.A., will be showcasing these technologies in Hall A1. This event serves as a critical networking hub for event professionals in the DACH region (Germany, Austria, Switzerland) and will likely act as a catalyst for further adoption of these communication standards.
