THE RF PERSPECTIVE
Wireless systems
are becoming less complex,
making an engineer’s life easier
Kevin Gwyther-Brown Business development manager, professional audio, Sennheiser
Historic and modern venues present particularly different RF environments. How do you strategise around that? Our approach to any new project is the same: we always consider all technologies that may be present, not just those related to RF. On-site RF scans and spectrum sweeps are sometimes required and are extremely valuable. Our focus is on developing and producing equipment that is not only reliable but also flexible to be deployed in any environment.
When faced with competing priorities, how do you ensure the audience’s experience remains intact? prioritise near-invisible integration, so that microphones and speakers seamlessly blend into the architecture, preserving the visual and functional integrity of the historic space. To meet artistic intent, we utilise our active acoustics system to provide dynamic flexibility, supporting the show’s creative vision through tailored acoustic presets developed collaboratively with musicians and directors. For instance, the system can instantly transition from intimate chamber acoustics to expansive cathedral-like reverberation to heighten dramatic effects. Crucially, the system’s geometric Fabio Kaiser When facing architectural limitations, we modelling ensures technical feasibility doesn’t detract from the artistic result. The calculated reflections naturally blend with the existing acoustics, making the audience virtually unaware that an enhancement system is in use. This foundational transparency ensures that, regardless
How do you see RF technologies evolving as production demands
continue to complexify?
Wireless ecosystems are becoming less complex. We are bringing ecosystems like Spectera to the market that simplify RF planning and management. Software such as Soundbase makes workflows easier. The ability to manage spectrum deployment across multiple brands, and even control these systems in a live environment, makes engineers’ lives simpler. Features such as live chat in a Soundbase project further enhance collaboration before and during an event. When working in heritage or architecturally sensitive spaces, how can modern RF technologies adapt to their restrictions? Spectera offers significant benefits for these types of deployments. For example, using antennae that run on Cat 5 cable enable runs of up to 100 metres without worrying about RF loss or thick cabling as was previously required. These can also be converted to run up to 4km on fibre, ideal for venues with long or complex cable paths. Additionally, the system now requires less rack space. A single, 1U Spectera base station can facilitate up to 64 channels of audio (32 in, 32 out) and four antenna ports, making deployment not only easier but far more flexible and stable in these environments.
of constraints, the sound delivered is impressively organic and immersive. Brandon Heinz We approach every project with the goal of delivering pristine, intelligible sound without compromising on design or intent. Our loudspeakers are engineered for both acoustic precision and architectural harmony. Being compact, discreet and aesthetically adaptable means sound enhances the space rather than drawing attention away from the main event. With technologies like Omnibeam, we can direct sound towards the audience while minimising reflections from walls, ceilings and glass surfaces. Furthermore, unlike traditional point source boxes or line arrays, steerable columns have a slender, narrow form that lets them visually blend into a space’s architecture. This marriage of sleek design and advanced precision audio ensures clarity and consistency, even in acoustically challenging or visually sensitive venues.
