A desktop arm designed for studio and streaming setups
Designed for recording studios, content creation, and multimedia workstations, this flexible arm offers a simple solution to save space and improve ergonomics. It keeps the microphone (or a holder for tablet and smartphone) perfectly accessible while freeing up desk surface for the keyboard, console, or controller.
Who it's for and intended uses
Ideal for podcasting, voice-over, videoconferencing, streaming, and home recording, it facilitates aligning the microphone at the correct distance, reducing adjustments and improving recording consistency. Its 800 g load capacity suits most dynamic microphones and many studio-format condenser microphones (depending on the shock mount and accessories used).
Stability, versatile mounting, and custom installation
Robust and adaptable clamp
The clamp covers a clamping range of 20 to 51 mm and fits both desk tops and tubular structures. Specially shaped clamping surfaces, quality plastic inserts, and non-slip support ensure a strong grip without unnecessarily marking surfaces.
Simplified cable management
The arm is supplied without cable to let you choose the length and type of connection suited to your audio interface or console. The included 4 cable ties allow you to neatly guide the cable along the arm and prevent it from pulling on the microphone during adjustments.
