Thickened solder pad and fixing clamp for a robust connection point The product uses a thickened solder pad and a thickened fixing clamp to create a strong, reliable electrical and mechanical connection. This reduces looseness and improves signal stability in live or mobile setups. Compatibility with D12, D21 and other lavalier wireless microphones Designed to work with D12 and D21 systems and other lavalier wireless microphones that use an M6 internal thread. It features an M6 x 0.5 internal thread for secure attachment to compatible devices. Goldplated plug for reliable contact and corrosion resistance The plug is goldplated to ensure low contact resistance, durable conductivity, and resistance to oxidation. This provides stable performance over time even in demanding environments. M6 x 0.5 internal thread The plug employs an M6 x 0.5 internal thread, providing a dedicated interface for wireless microphone components and ensuring a secure, repeatable fit.
