New igus e-spool Microphone Reeler Enhances Sound Quality for Professional Audio Engineers
e-spool microphone allows for automated feeding of microphone cables that are up to 30m long; doing without slip ring optimizes sound quality
25 November 2024 – In response to the demanding needs of sound engineers in theaters, opera houses, and television studios, igus® has introduced the e-spool® microphone, an innovative cable reeler designed to streamline operations and enhance sound quality. The e-spool microphone, equipped with an electric motor, allows automated deployment of microphone cables up to 30 meters in length without requiring a slip ring, ensuring uninterrupted and high-quality audio transmission.
The e-spool microphone caters to sound engineers who manage extensive sound installations under intense time constraints. By automating the release and retraction of microphone cables, this advanced reeler reduces setup time and minimizes risks associated with manual handling, such as cable breakage.
“The e-spool microphone was developed to relieve technicians from the strain of manual cabling while preserving the integrity of microphone cables,” stated Michael Berteit, Sales Manager for Engineering Projects and Installation Services at igus.
Optimized Sound Transmission Without Slip Rings
In designing the e-spool microphone, igus focused on achieving optimal sound quality by eliminating traditional slip rings, a common source of audio interference in conventional reelers. Rather than using a slip ring, which can degrade signal quality and increase system complexity, igus incorporated its proprietary twisterband technology.
The igus twisterband comprises interlocking plastic chain links that maintain a continuous connection that supports rotations up to 7,000°, allowing uninterrupted signal transmission and exceptional sound clarity.
“By using twisterband, we ensure an uninterrupted signal that remains less prone to interference,” explained Berteit. “This approach enables sound engineers to provide audiences with high-quality sound without the operational drawbacks of conventional reelers.”
“A cable break is like a dark cloud at the back of most sound engineers’ minds,” added Berteit. “With our specially developed system and safety features, we want to give them a sense of security so that they can concentrate better on the creative aspect of their work.”
