Solution Configuration Instructions

1. Sound Reinforcement System: The sound reinforcement system focuses on the clarity of speech, transmission gain, sound pressure level, sound field uniformity, and music playback quality, all of which can be achieved through digital audio processing. The system mainly consists of speakers, power amplifiers, mixers, microphones, and audio sources, capable of meeting the needs of simple conferences, speeches, and seminars. DMX12, D6576, and D6675, as professional audio processing devices, ensure clear speech on-site, free of distortion and feedback howling. Four D6564 speakers provide sufficient sound pressure margin, even sound field distribution, and precise sound image localization.

2. Conference Speech System: The conference system uses the D7101 host, with delegate units D7151 and D7152 for speeches. Audio signals are routed through the DMX12 mixer to the D6675 processor, then to the MX2500II amplifier, and finally to the D6564 speakers, achieving local sound reinforcement. Since a desktop conference format is used, gooseneck microphones and wireless handheld microphones are selected. The microphones are connected to the mixer for control, ensuring simple and convenient operation.

3.  Video Display System: One D7129 camera is controlled via the D7101 conference host to achieve camera tracking and positioning. The video screen is output to a projector or monitor, and the speaking delegates can be known in real time.

Function Features-D7101

• A conference system can support up to 4096 conference units.

• It features a built-in DSP networked audio processor that delivers uncompressed, high-quality sound.

• The high-fidelity networked wiring design ensures excellent microphone stability and strong anti-interference capabilities.

• It supports five conference modes: FIFO (First In, First Out), normal mode, voice mode, free mode, and apply mode.

• The system offers full-conference recording, with both automatic and manual recording options available.

• It includes a speech timing and ccountdown reminder for the end of speech. Additionally, it supports remote control to turn microphones on or off.

• The +5V alarm trigger voltage input interface is used in conjunction with the alarm audio input for emergency alarm barge.

• There are four 100Mbps +48V powered RJ45 network interfaces for network transmission protocols and +48V power supply to connected conference units.

• The system supports both wired conference unit connections and 5G WiFi wireless conference units, offering three connection options: pure wired, pure wireless, and mixed wired-wireless.

• The system can be paired with a simultaneous interpretation system for real-time translation, ensuring that participants can understand the speech content instantly.

Product Introduction_D7151/D7152/D7153/D7154

This series of conference units features a 4-inch high-definition touchscreen and integrates functions such as speaking, sign-in, voting, and information display. It is equipped with a cardioid directional condenser microphone, along with a microphone activation indicator and a button light switch indicator. Additionally, it includes a headphone jack for monitoring, with separate volume controls for monitoring and microphone levels.

(Network Conference System Host) D7101

Dual-Machine Hot Backup Function

• One conference host can be set as the main unit, while another is configured as a backup (slave) unit and connected to the system. In the event of an unexpected failure of the main unit, the backup unit will be automatically activated to ensure that the meeting proceeds smoothly without interruption.

Camera Tracking Function

• The host integrates a camera tracking system, supporting up to six camera inputs and one HD output. By pre-configuring corresponding positions, the system enables automatic camera tracking when the microphone’s speak button is pressed.

Strong Anti-Interference Capability

• By utilizing analog-to-digital (A/D) and digital-to-analog (D/A) conversion technology, digital signals are encoded and transmitted over the network. This fundamentally resolves issues such as equipment interference, distortion crosstalk, and signal attenuation over long-distance transmission. Network-based transmission significantly enhances the system's anti-interference capability.

Case Studies

The D7101 conference system is suitable for various meeting scenarios, such as internal corporate meetings, international summits, academic seminars, and command and dispatch operations, where it plays a crucial role.
