4. Setup and Installation
4.1 Attaching the Desk Clamp
- Choose a sturdy desk or table surface with a thickness between 10mm and 60mm.
- Place the desk clamp onto the edge of the chosen surface.
- Tighten the screw mechanism on the clamp until it is firmly secured to the desk. Ensure it does not wobble.

4.2 Mounting the Boom Arm
- Insert the base pin of the microphone boom arm into the hole on the top of the securely fastened desk clamp.
- Ensure the arm is fully seated and can rotate freely within the clamp.
4.3 Attaching the Microphone
- Identify the thread size of your microphone or shock mount. The boom arm features a 5/8" thread.
- If your microphone requires a 3/8" thread, use the included 3/8" to 5/8" adapter by screwing it onto the boom arm's thread first, then attach your microphone or shock mount.
- Carefully screw your microphone or shock mount onto the boom arm's thread until it is secure. Do not overtighten.


4.4 Cable Management
- Route your microphone cable along the boom arm.
- Utilize the integrated cable management clips to secure the cable neatly along the arm, preventing tangles and ensuring a clean setup.

5. Operating Instructions
5.1 Adjusting the Arm Position
The Maclean MC-898 features multiple adjustable joints for flexible positioning:
- Rotation: The arm can rotate 360 degrees at its base connection to the desk clamp.
- Angle Adjustment: The joints along the arm allow for tilting and angling. Loosen the adjustment knobs at each joint, position the arm as desired, and then tighten the knobs to secure it.
- Height Adjustment: The arm's height can be adjusted within a range of 338mm to 949mm. Adjust the angles at the joints to achieve the desired height and reach.


5.2 Optimal Microphone Placement
Position your microphone to capture the best audio quality while maintaining comfort. Experiment with different distances and angles relative to the sound source (e.g., your mouth) to find the ideal setup for your specific needs.
6. Maintenance
- Cleaning: Wipe the boom arm with a soft, dry cloth to remove dust. For stubborn marks, use a slightly damp cloth and mild soap, then dry thoroughly. Avoid abrasive cleaners.
- Joints and Fasteners: Periodically check all screws and adjustment knobs to ensure they are tight. If the arm feels loose, gently tighten the relevant fasteners.
- Cable Management: Ensure cables are properly routed and not pinched or excessively bent, which could lead to damage.
7. Troubleshooting
- Arm does not hold position: Ensure all adjustment knobs are sufficiently tightened. If the issue persists, check the weight of your microphone; it may exceed the maximum capacity of 1 kg.
- Arm feels wobbly: Verify that the desk clamp is securely fastened to the desk and that the boom arm is fully inserted into the clamp's receiver.
- Difficulty rotating the arm: Check for any obstructions around the base or joints. Ensure no cables are caught in the rotation mechanism.
