The Rycote ConnBox microphone cable connector boxes are designed to mount on the Rycote Suspension system. The ConnBox serves as a solution for 2 major problems associated with microphone shock isolation. Rigid microphone cables often deny true microphone isolation, weighing the microphone down and causing noise from movement and vibration to reach the microphone. Noise and rattling due to bulky cable connections can cause problems as well.
The ConnBox simply connects between the microphone and input device. Being that the ConnBox mounts to the Suspension system, the microphone cable is given the necessary slack needed to achieve true noise free isolation. This ConnBox features a hardwired output cable (XLR 3-pin or 5-pin connection depending on model) and an input connector that is compatible with the Sennheiser MZL series remote cables, that are used with the MKH8000 microphone.
