Set up a mic boom arm by clamping it to the desk, fitting the mic on the thread adapter, routing the cable through the channels, and setting the arm height and angle so the mic sits at mouth level. Check the desk thickness and the mic weight against the arm, then tighten the clamp and the joints.
Clamp the arm to the desk
Start with the clamp. The FIFINE clamp fits a desktop 0.8 to 2.4 in thick, the Rode clamp fits desks up to 70 mm thick, and the InnoGear clamp clips to any desk up to 2 inches thick. Set the clamp on a flat edge of the desk and tighten it until the arm stays put. The FIFINE arm has a section near the C-clamp that cannot be adjusted up to down, so set the clamp position before tightening.
Fit the mic on the arm
Fit the mic on the thread adapter that matches it. The FIFINE arm comes with 1/4 in to 3/8 in and 3/8 in to 5/8 in adapters on a rotatable ball-head, the Elgato arm comes with 1/4 in to 3/8 in and 1/4 in to 5/8 in adaptors, and the Rode arm fits both 3/8 in and 5/8 in mic mounts. The InnoGear arm has a 5/8 in metal connector. Check the mic weight against the arm: the Rode arm holds mics 0.25 kg to 1.2 kg, and the InnoGear arm holds up to 3.5 pounds.
Set the height and the angle
Set the arm so the mic sits where you speak. The FIFINE arm extends to 29 inches and adjusts up to down by 220 degrees and horizontally by 360 degrees. The Elgato arm has a 740 mm horizontal reach, with 360-degree horizontal and 90-degree upper vertical rotation. The InnoGear arm adjusts 135 degrees back and forth and 180 degrees up and down, with a base that rotates 360 degrees. The Rode arm rotates 360 degrees with full extension.
Route the cable through the channels
Run the mic cable through the arm's cable channels so it stays out of the way. The FIFINE arm has built-in cable management, the Elgato arm has magnetic cable channels with covers, the Rode arm has integrated cable management that keeps XLR runs hidden, and the InnoGear arm has built-in channels with rubber cable covers. Remove the covers, lay the cable in, and put the covers back.
