Sennheiser EW-D EM Color Coding Magnetic identification ring set

The Sennheiser EW‑D EM Colour Coding Set is a professional accessory consisting of magnetic identification rings designed to facilitate the visual organisation of EW‑D EM receivers in live, broadcast or complex installation environments. The set includes 16 distinct colours.
Made of ABS plastic with a magnetic back, the rings can be easily attached to the surface of the receiver, allowing for quick identification without the need for tools. Thanks to the high-contrast colours, the immediate pairing between transmitter and receiver is simple even under stage lighting and variable environmental conditions.
From an operational standpoint, the set supports the identification of up to 16 different wireless channels, improving workflow during configuration, management of multiple devices, and real-time operations.

Its compact size makes the system discreet yet effective; however, some technicians report that visibility from a distance may be limited.
In summary, the Colour Coding Set offers an elegant and robust solution for maintaining order and clarity in EW‑D systems, reducing pairing errors and speeding up setup on stage or in the studio.
