D7702 Omnidirectional Ceiling Microphone Solutions for Conference Rooms

 II. Market Demands

Drawbacks of Traditional Handheld Microphones

• Limited pickup range: Handheld microphones need to be aimed directly at the speaker’s mouth, resulting in a relatively narrow pickup range, which is not suitable for meetings or discussions with multiple speakers.

• Frequent passing requirements: In meetings with several participants, the handheld microphone must be passed between different speakers, which may interrupt the flow of the meeting.

• More susceptible to echo and interference: Due to their directional nature, handheld microphones are more likely to be affected by echoes and background noise from the surrounding environment.

• Complex installation and usage: Handheld microphones may need to be connected to complex sound systems and require adjustments and testing during use.

• Narrow applicability: Handheld microphones are better suited for performances and speeches, making them less versatile in meetings with multiple participants.

Launch of the D7702 Omnidirectional Ceiling Microphone

• Wide pickup range: The omnidirectional microphone can evenly capture sound within a 360-degree radius, eliminating the need to aim directly at the speaker, making it suitable for meetings or discussions involving multiple participants, unlike handheld microphones that require direct alignment with the speaker’s mouth.

• Reduced passing requirements: In traditional handheld microphone scenarios, microphones often need to be passed between different speakers. The omnidirectional microphone eliminates this need, enhancing the flow of the meeting.

• Minimized echo and interference: Omnidirectional microphones are typically designed to reduce echo and background noise, providing clearer audio quality.

• Easy installation: Omnidirectional microphones are generally easy to install. It can be installed at the center of the conference table or on the ceiling without the need for complex wiring and setup.

• Facilitated recording and transcription: Omnidirectional microphones can be easily connected to recording devices or meeting documentation systems, making it convenient to record and transcribe meeting content.

 VI. Product Highlights

 VII. Camera Tracking

System Connection Diagram

The D7702 omnidirectional ceiling microphone needs to be integrated with the central control system to achieve camera linkage and face tracking functionality. The D7702 device has a built-in TCP server (see red box below), and the central control system needs to implement a TCP client (see yellow box) to communicate according to the agreed protocol.

 VIII. Functional Features - D7702

D7702 is a newly launched high-end ceiling conference microphone. It integrates up to 128 units of omnidirectional microphone array, providing 16 independent configurable pickup zones for refined pickup configuration. It adopts Dante digital audio technology to ensure stable audio transmission and wide compatibility. DMC700 incorporates AI algorithms, providing functions such as AI noise suppression, AI reverberation suppression, AI adaptive feedback control (AI-AFC), and AI echo cancellation, effectively improving meeting efficiency.

 IX. Functional Features - D7702

The Audio Controller is an interface configuration tool for Ceiling Microphones. Use this tool to adjust the sound pickup area of the conference room and configure different parameters for different conference rooms. (Current software version is only available for WINDOWS system.)
