4. Attainable Functions
1. Pop-up microphone
This product is a concealable cardioid condenser boundary microphone, which is made of high-quality brass, with built-in anti-vibration pad and RF filter. What makes it unique is that the interior design is based on the principle of mechanical structure expansion. When the microphone is not in use, the user can hide it without removing it from the desktop.
2. Expandable communication capability
It adopts full digital high-fidelity circuit development and design, uses unique digital technology to further improve the reproduction of the microphone and the transmission speed of the sound to reduce the sound loss, and ensure the high-fidelity audio of the microphone tone. The host has 3 channels of 8-pin dedicated conference unit connection ports, and each channel supports 20 chairman/delegate units. The host can connect up to 3 expansion hosts D6115E and up to 240 conference units, each expansion host has 6 channels of 8-pin dedicated conference unit connection ports, and each channel supports 10 chairman/delegate units.
3. High-fidelity sound quality design
Take the unique high-fidelity audio processing circuit and built-in RISC high-performance CPU as the core for stable system and fast calculation, and adopt 32-bit high-speed DSP floating point processing, with high bandwidth, acoustic feedback suppression, echo cancellation, noise cancellation, digital equalization effects, and automatic gain, to effectively prevent feedback and interference, and ensure the perfect and clear sound quality, confidentiality and security of the meeting.
4. Multi-mode speech function
Can be operated independently or with an external computer combined with software for synchronous linkage operation to realize a variety of conference management functions (conference mode or operation: designated speech, free speech, application speech and first-in first-out speech, etc.) Standalone machine can realize the following conference functions: free mode, limit mode, first-in first-out mode.
5. Microphone automatic ON/OFF function
The microphone has automatic ON/OFF function. When the microphone is turned on and there is no pickup sound (when the sound is less than 50dB in the pickup range), it will automatically turn off after 45 seconds. Can choose the number of speaking mics at the same time from 1-9 (inclusive) or free-mode speech.
6. Hand-in-hand connection of conference mics
The conference unit is embedded in the conference table and is equipped with a “T”-type connector. The male end of the main cable of the T-type line is inserted into the female end of the extension cord according to the indication signs. The extension line is inserted into the 8P-DIN socket of the attending machine, and the other attending machines are connected in turn. If there are many conference units in the system, it can use multiple-way connections.
7. Can realize telephone conference and speaker positioning and tracking
The host has the connection terminal for the telephone coupler to connect the telephone coupler for telephone conference, and the external video central processor to realize the function of speaker positioning and tracking.
8. Sound reinforcement system
In terms of sound reinforcement, it focuses on the clarity of speech sound reinforcement, sound transmission gain, sound pressure level, sound field uniformity, and music playback sound quality, which can be achieved through digital audio processing. The system is equipped with a mixer MG12 for audio access in the conference room. In addition, the professional audio processing equipment D6575 makes the language on the scene clear, no distortion and no feedback howling. 8 full-range high-fidelity ceiling speakers in the conference room meet the needs of the venue’s sound field, and 1 dual-channel fixed-impedance stereo power amplifier is used to promote sufficient on-site sound pressure margin, uniform sound field, and accurate sound image positioning.
