Digital Conference System Solution for Multiple Meeting Scenarios D7111

 II. D7111 Dual Conference Room Solution

Note: The D7111 series conference microphones are supplied with a Square Microphone Rod by default. A Gooseneck Microphone Rod is available upon request and requires customization when placing the order. This solution is provided for reference only. For specific requirements, please feel free to contact us.

 Solution Configuration Description

Conference Room Scale and Configuration:

• Conference Room A (Main Conference Room / Discussion Room 1):

• Size: 120–200 m²

• Conference Unit Configuration: 1 Chairman Unit + 15 Delegate Units (including 2 VIP Units)

• Sound Reinforcement System: Independently configured mixer, amplifier, and speakers, connected to the “Zone 1” output channel of the main unit.

• Conference Room B (Sub-Conference Room / Discussion Room 2):

• Size: 120–200 m²

• Conference Unit Configuration: 1 Chairman Unit + 10 Delegate Units (including 1 VIP Unit)

• Sound Reinforcement System: Independently configured mixer, amplifier, and speakers, connected to the “Zone 2” output channel of the main unit.

Summary of Core System Configuration and Implementation:

• Host Mode: “Dual Conference Room Mode” is enabled. The host’s internal audio processing and control logic operate independently, serving Conference Room A and Conference Room B separately.

• Network Architecture: High-performance PoE switches are used to connect the conference units of Conference Room A and B via separate VLANs, ensuring data isolation.

Audio Processing and Output:

• Audio signals from Conference Room A are output to Channel 1 (Zone 1) for its sound reinforcement system.

• Audio signals from Conference Room B are output to Channel 2 (Zone 2) for its sound reinforcement system.

• Each sound reinforcement system has independent volume, EQ, and delay adjustments, without affecting the other.

Functional Applications:

• Both conference rooms can independently manage check-in, voting, and speaking rights.

• Supports “Discussion Function,” allowing both conference rooms to conduct independent group discussions and record audio.

Key Advantages

• Dual Use with One Host: Reduces equipment procurement and space costs.

• Independent Management: Administrators can operate simultaneously without cross-permission conflicts.

• High-Fidelity Sound Reinforcement: 20-zone matrix ensures independent, high-quality audio for each room.

• Flexible Expansion: Additional conference rooms or devices can be easily added.

 III. D7111 Application Solution for International Conferences

Note: The D7111 series gooseneck conference microphones require a custom order.

 System Configuration Description

Conference Room Scale and Configuration:

• Size: Large venue accommodating approximately 200–300 participants

• Layout: Includes a Chairman, Delegate Seating, Interpretation Booth, and Technical Control Area

Conference Unit Configuration:

• Chairman/VIP Units: 6 Chairman Units + 32 VIP Units (placed at the Chairman and key seats)

• Delegate Units: Approximately 150 wired Delegate Units (connected in a daisy-chain configuration with ring backup support)

• Interpreter Units: 6 interpreter units with corresponding 6 language channels, providing wired headset access for participants

• Video System: Equipped with a “4-in-2-out seamless video matrix module” to integrate multiple camera signals, perform seamless switching, and output to large displays

Core System Configuration and Implementation:

Interpretation and Simultaneous Translation System:

• Interpreters listen to the original audio channel through the host’s interpretation function and translate it into six language channels (CH1–CH6). The system supports ≥20 simultaneous translation channels, allowing independent recording for each language. Audio signals can also be output to infrared transmitters or wireless audio systems for participant listening.

Audio Matrix & Zone Sound Reinforcement

• The built-in audio matrix handles mixing and zonal management for the venue.

Video Linkage & Camera Tracking

• The integrated camera tracking system controls cameras via RS422. When a conference unit speaks, the system automatically calls presets to quickly locate the speaker. The video matrix module supports 2–4 camera inputs for seamless switching, enhancing the visual experience.

High Reliability Assurance:

• Conference units are connected via a “ring-based dual-link” to ensure stable operation. The main/backup host configuration supports automatic switching, guaranteeing uninterrupted meetings. Conference units support multiple speaking modes to maintain orderly meeting management.
