MP9866 Digital Conference System

DSPPA new generation of pure speech digital conference system perfectly combines 8-pin cable hand-in-hand connection and dual-backup full digital intelligent control technology of network interface. The system is easy to operate and install. Besides, the system adopts high-speed CPU program editing control, and high-fidelity circuit design to reproduce the original sound quality; the system supports automatic detection of system unit, innovative speech mode settings, and time-limited speech function settings, becoming a new generation of multifunctional conference system, which is an ideal system for various types of projects such as multi-functional conference rooms in hotels, governments, enterprises, etc.

Attainable Functions


1. Multiple styles of microphones available
This digital conference system has designed different styles of microphones for customers to choose according to their different needs. The long conference microphones (CM60 and CM61) and the square microphones (CM63 and CM64) are both discussion and speech units; and the conference microphones (CM67 and CM68) are long microphones with built-in speakers; all those three styles of microphones can be connected via 8-pin dedicated conference cable and CAT5/6 network cable, for stable and reliable transmission, and convenient installation.
2. Adopt dual system dual backup multi-channel system unit connection
It adopts all-digital high-fidelity circuit development design, fully combines unique digital technology, network technology and digital audio technology to achieve high-speed data transmission under high-bandwidth conditions, thereby further improving the reproduction of the microphone sound and the transmission speed of sound to reduce sound loss and ensure high-fidelity audio of the microphone tone. It has 2-channel 8-pin dedicated conference unit connection ports, supporting 25 units each, and 4 RJ45 network cable connection ports, supporting 20 units each.
3. High-fidelity sound quality
It adopts a unique high-fidelity audio processing circuit and built-in RISC high-performance CPU as the core for stable system, fast calculation, and adopts 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. Auto detection of system unit, with conference recording function
When connected to the host, all conference units can display the usage status in real time. When the indicator light is on, the host starts to detect automatically. At this time, all lines are working normally. With a recording output interface, all conference records can be fully recorded and saved.
5. Adopt LCD display screen for more intuitive and user-friendly operation
Adopt a 1.77-inch true-color display screen to display system menus and host status and other information, and centrally control all conference functions through the panel navigation keyboard.
6. Multi-mode speech function
The system speech mode has first-in-first-out, last-in-first-out, auto mode, discussion mode, chairman mode, etc. The chairman unit can use the priority button (Priority) to control the speaking sequence and control the atmosphere of the meeting. Under the voice control setting (allowed mode), if you speak to the microphone head of the microphone unit when the microphone unit is not turned on, the microphone will be automatically turned on.
7. Hand-in-hand connection for conference units
The system connection uses low-voltage DC24V safe voltage to ensure the user’s personal safety for high safety, low energy consumption and environmental protection.
The conference unit can be used in two ways: CAT5e (CAT6 or CAT7) network cable with RJ45 crystal plug or 8-pin dedicated conference cable, according to the user’s needs, effectively resisting interference, with more convenient installation and more reliable transmission.
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 MG12 mixer for audio access in the conference room. In addition, D6575 is used as a professional audio processing device for clear language without distortion and feedback whistling. The 2 professional full-range high-fidelity wall mount speakers in the conference room meets the needs of the sound field in the conference room; 1 dual-channel constant-resistance stereo amplifier promotes sufficient on-site sound pressure margin, uniform sound field; accurate sound image positioning, etc.
