Most studio and podcast microphones mounted on desk arms or boom mounts cannot use a standard 40mm mic cube. This is because mic cubes are designed to slide onto a hand-held microphone barrel, not a fixed mount connection.
Where the mount connection allows, this issue can be solved quickly and cleanly using a simple extension tube.
A simple extension tube solution
The extension tube creates the correct spacing between the microphone and the mount, allowing a branded mic cube to sit securely without modifying the microphone or mount.
The mic cube is held firmly in place by its acoustic foam insert, delivering a professional on-camera result suitable for studios, podcasts, and shared recording environments.
How it works
- Unscrew the connector above the microphone
- Screw in the extension tube (3/8” or 5/8”)
- Slide the branded mic cube onto the tube
- Screw the microphone onto the other end
- Align and hand-tighten
The entire setup takes only minutes.
Fast branding changeover
- Connected in minutes
- Removed in minutes
- Easy cube swaps for different podcasts or shows
- No modification to the microphone
This makes the system ideal for shared studios, rotating presenters, or organisations running multiple programs from the same setup.
