Frequently Asked Questions
Where are omnidirectional boundary microphones typically used?
Omnidirectional boundary microphones like the U841R are ideal for boardrooms, conference tables, and broadcast settings where you need to pick up sound equally from all directions. The super-compact design (65 mm diameter) provides discreet, low-visibility coverage.
What does the UniGuard RFI-shielding technology do?
UniGuard RFI-shielding protects the microphone from electromagnetic interference commonly found in broadcast and office environments, ensuring intelligible audio without the hum or noise typical of unshielded equipment.
Is a boundary microphone placed on a table or mounted overhead?
Boundary microphones are designed to mount on a surface—typically a conference table, floor, or wall—where they pick up sound efficiently through the reflecting plane. This placement is key to their directional behavior and low visibility.
Can a single omnidirectional boundary microphone cover an entire boardroom?
For small to medium boardrooms or focused applications, a single U841R can provide adequate coverage. For larger conference tables or spaces, multiple microphones or a multi-channel model may be needed. Contact Procure.ae to discuss your room layout and requirements.
How does the low-profile design benefit broadcast and recording?
The low-profile, 65 mm diameter design keeps the microphone discreet and out of sight on-camera or in the set background. This allows broadcast studios and recording spaces to maintain a clean visual appearance while capturing high-quality audio.
Does the U841R pick up unwanted noise from the surface it sits on?
The U841R is engineered to minimize vibration pickup from the mounting surface through its boundary design. However, placing the microphone on a stable, isolated surface (away from vibrating equipment or foot traffic) will improve audio quality.
What is the typical delivery timeframe for boundary microphones in the UAE?
Procure.ae supplies boundary microphones across the UAE and GCC on a request-a-quote basis. Contact the team to confirm current lead times and availability.
Will Procure.ae assist with installation and surface mounting?
The Procure.ae team can advise on installation and mounting requirements for your boundary microphone. Please reach out to discuss what setup support is available for your application.
What is the polar pattern of the U841R omnidirectional boundary microphone?
The U841R is omnidirectional, meaning it picks up sound equally from all directions when placed on a surface. This makes it ideal for capturing speech from multiple speakers around a boardroom table.
Does the U841R operate on phantom power?
Yes, the U841R is a condenser microphone and requires phantom power to operate. This power is supplied via the XLR cable from your mixing console or audio interface.
What does the compact 65 mm diameter of the U841R mean for installation?
The 65 mm diameter is exceptionally small, making it easy to position on a conference table or mount on a wall or ceiling without dominating the visual space. This compact size is a key advantage in professional broadcast and recording environments.
