Samson MBA18 18-inch Telescoping Microphone Boom Arm with C-Clamp Desk Mount
Eighteen inches is the short reach in Samson's boom arm range, and that is the point of the MBA18. It puts the microphone in front of your face on a normal desk without a long arm swinging out over the keyboard, which suits a single-person podcast, radio or home studio position where you are always in the same seat.
- Telescoping, not articulating: the arm extends to a maximum horizontal or vertical reach of 18 inches, so adjustment is a straight in and out rather than a set of folding joints.
- C-clamp mount: attaches to a table or desk with a maximum grip of 2 inches, which covers most desktops and worktops.
- 5/8 inch to 27 threading: the standard mic clip thread, so it accepts the clip or shockmount you already have.
- Holds up to five pounds: enough for the large diaphragm condensers and broadcast dynamics people usually put on a desk arm.
- Steel and plastic construction: a light arm for a light footprint on the desk.
Samson lists the MBA18 for work from home, content creation, audio for video and education. If you need to reach across a wider desk or share the mic between two positions, look at the 48-inch MBA48 instead.
The MBA18 Microphone Boom Arm is a desk arm for any radio, podcast or home studio setup. What separates it from the longer arms in the range is simply how far it reaches, and that single number decides whether it is the right one for your desk.
What 18 inches actually changes
A maximum horizontal or vertical reach of 18 inches is enough to bring a microphone from the edge of a desk to just in front of your mouth. It is not enough to swing a mic across a wide desk to a guest on the other side, and that is deliberate. A short arm stays out of the way of monitors, keyboard and notes, and it does not need a counterweight fight to hold position. For a fixed one-person recording position, short is easier to live with.
Telescoping design
The MBA18 uses a telescoping design rather than a folding articulated one. Extending and retracting is a single straightforward movement, with fewer joints to loosen over time. In combination with its steel and plastic construction, the arm stays light on a desk that is already carrying an interface, a monitor and a laptop.
Mounting and what it will hold
The arm attaches to a table or desk through its C-clamp mount, which offers a maximum grip of 2 inches. Measure the thickness of your desktop before ordering, as that figure is the limit. On top, the MBA18 offers 5/8 inch to 27 mic clip threading, the standard thread that mic clips and shockmounts use, and it accommodates any microphone weighing up to five pounds. That comfortably covers USB condensers, large diaphragm studio condensers and broadcast dynamics.
Where it fits
Samson lists the MBA18 for work from home, content creation, audio for video and education. It is the arm for a desk that has to be a workstation for the rest of the day. If you need to cover a wider surface, reach a second seat, or mount permanently through a flange, the 48-inch MBA48 is the one to compare it against.
