Frequently Asked Questions
What is a touch-sensitive capacitive switch on a boundary microphone?
The touch-sensitive capacitive switch on the U891Rb allows you to control the microphone's mute and on/off modes simply by touching the surface. This is especially useful in boardroom settings where you want quick, intuitive control without physical buttons.
What are the three touch-control modes on the U891Rb?
The three modes are: touch on/off (toggles between mute and active), press to talk (active only while touching), and press to mute (toggles mute state). This flexibility allows different boardrooms to use the microphone in the way that suits their meeting style best.
How does the RGB LED status indicator help during meetings?
The RGB LED provides visual feedback showing whether the microphone is active or muted. This reassures speakers and attendees that their audio is being captured, reducing confusion and technical anxiety in boardroom and conference environments.
Is the U891RCb contact closure feature useful for integrated conference systems?
Yes, contact closure capability means the U891RCb can trigger external devices such as cameras, lighting systems, or video conferencing equipment directly from the microphone. This enables seamless integration in modern smart conference rooms.
What is the difference between the U891Rb and U891RCb models?
Both have touch-sensitive controls and RGB LEDs. The U891RCb adds external remote switching capability and contact closure, making it suitable for integrated systems where the microphone needs to control external cameras or devices.
Can the touch controls on the U891Rb be disabled to prevent accidental muting?
For information on control locking, mode selection, and firmware configuration options for the U891Rb, contact Procure.ae. They can advise on setup options for your specific boardroom needs.
What is the lead time for boundary microphones with touch controls in the UAE?
Procure.ae supplies professional boundary microphones, including touch-control models, across the UAE and GCC on a request-a-quote basis. Contact the team to confirm current lead times.
Does Procure.ae provide firmware or configuration support for smart conference microphones?
The Procure.ae team can discuss configuration, setup, and integration support for touch-control and smart boundary microphones. Please reach out to learn what options are available for your installation.
What is the polar pattern of the U891Rb?
The U891Rb is a cardioid condenser boundary microphone, designed for surface mounting with directional rejection perpendicular to the table. This provides focused pickup of speakers around a conference table.
Does the U891Rb operate on phantom power?
Yes, the U891Rb requires phantom power to operate. Additionally, it features an RGB LED status indicator that may have its own power requirements—contact Procure.ae for specific power specifications.
What is included with the U891RCb—does it come with a remote control?
The U891RCb includes touch controls and contact closure capability for external device triggering. For details on what accessories, remote controls, or cables are included in the package, contact Procure.ae.
