Setup
1. Choose Your Mounting Option
The MBA38 offers two versatile mounting options:
- C-Clamp Mount: Ideal for temporary or non-permanent installations. Attach the C-clamp to the edge of your desk or table (up to 2 inches thick) by tightening the screw mechanism until it is secure.
- Flange Mount: For a more permanent setup, the flange mount can be screwed directly into a surface using the provided wood screws. Ensure the surface is sturdy enough to support the boom arm and microphone.
2. Attach the Boom Arm
Insert the base of the boom arm into the chosen mount. The arm should slide smoothly into place and rotate freely within the mount.
3. Attach Your Microphone
Screw your microphone or microphone clip onto the 5/8"-27 threaded post at the end of the boom arm. Ensure it is securely fastened.
4. Cable Management
Utilize the integrated cable management straps or the groove along the arm to neatly route your microphone cable. This helps maintain a clean setup and prevents cable interference during adjustments.

Operating Instructions

Maintenance
- Regularly wipe down the boom arm with a soft, dry cloth to remove dust and debris.
- Check all mounting points and connections periodically to ensure they remain secure.
- Avoid applying excessive force or hanging heavy objects on the boom arm beyond its 5 lb (2.3 kg) weight capacity.
Troubleshooting
- Arm not holding position: Ensure your microphone and any accessories do not exceed the 5 lb weight capacity. Check that the mounting clamp or flange is securely fastened to the surface.
- Excessive noise during movement: The internal springs are designed for silent operation. If you experience unusual noise, ensure the arm is clean and free of obstructions. Avoid over-lubricating the joints, as this can affect tension.
- Mounting instability: If using the C-clamp, verify your desk thickness is within the 2" maximum grip. For flange mounts, ensure screws are properly seated in a solid surface.
