MCU-S9 – Central controller
- Utilizing DSP/DD0V digital transmission and processing technology and adhering to the latest international standards:
- Time-Distorted Multiplexing (TDM), 12-channel 32-bit PCM
- Aluminum alloy panel equipped with a 128×64 color LCD touchscreen for flexible use; system setup can be completed without a computer to improve debugging efficiency
- Connects up to 75 delegate microphones simultaneously and can be expanded to up to 600 microphones when connected with 8 auxiliary controllers
- Integrates conference discussion, video monitoring, electronic login, and voting/election functions (Yes, No, abstain)
- It has seven meeting modes: first-in, last-in, limited number, speech timer, voice-controlled start, chairman’s permission, and free discussion.
- The number of speakers simultaneously can be set to 1/2/3/4/5/6/8 (Maximum 2 chairpersons and 8 delegates)
- Maximum cable length: 50M from the central control unit to the last delegate microphone
- Applies high-fidelity lossless audio transmission technology, with an audio sampling frequency of 98KHz and a frequency response of 18Hz-34KHz;
- Uses an ID addressing method; the number of units can be customized to ensure a unique ID number, effectively avoiding duplicate ID conflicts;
- It has a hot-swappable function upon power-on, supporting automatic repair and quick localization of system errors without affecting the operation of other devices;
