A stage and orchestra standard for better volume exposure management
Designed to meet the demands of noise exposure reduction in group settings, the K&M 11900 aligns with the brand's philosophy: robust, practical, and durable solutions for the stage, pit, and rehearsals. Its compact size and thoughtful design effectively protect the musician without trapping the sound, making it a relevant choice for both orchestras and amplified ensembles seeking better control over sound projection between stands.
Who and in what situations to use the K&M 11900?
This acoustic shield is ideal for instrumentalists playing in the front line facing other performers: strings in front of brass, woodwinds in front of percussion, or pit musicians in theater. It is also suitable for live studio setups, music schools, and rehearsals where auditory fatigue needs to be limited without altering the overall ensemble balance. Thanks to its adjustable height, it easily adapts to sitting or standing positions and allows adjustment of the protection area depending on the instrument and the direction of sound sources.
