French NEXO speakers once again contribute to the World Internet Conference

From November 23 to 24, 2020, the Seventh World Internet Congress was held at the Internet International Convention and Exhibition Center in Wuzhen, Zhejiang Province, focusing on the themes of scientific prevention and control of the epidemic, promoting digital economy and scientific and technological innovation, and helping to resume work and production. Guests from domestic and foreign government departments, international organizations and leading enterprises in the Internet field are invited to carry out an overall and forward-looking exchange of ideas to respond to general concerns at home and abroad. Lead the trend of digital technology innovation.

More than 500 delegates from more than 20 countries and regions attended the conference, covering all kinds of leading scientific and technological achievements in the world. In order to share these advanced technologies clearly with the participants, the quality of sound reinforcement has become a key factor in this meeting. With the experience of the previous session, we use the NEXO special simulation sound pressure test software NS-1 to adjust the speaker deployment, and finally determine the type and number of speakers.

In the field, the linear array composed of M28 full-frequency speakers in the modular STM series is used as the main sound reinforcement. The biggest feature of M28 is the combined use, for different sites, by increasing or decreasing the number to meet the needs of the site sound pressure. With the pin buckle design between the two pairs, a single person can complete the assembly and hanging to meet the needs of rapid installation and disassembly. Two 8-inch low-frequency units and a 2.5-inch high-frequency voice coil can make the peak sound pressure reach 141dB and perform well in the frequency response 65Hz-19kHz.

With 2 STM S118 ultra-low frequency speakers on each side (18-inch low-frequency drive unit with peak sound pressure up to 143dB). Reduce the frequency response range to 27Hz to meet the low frequency demand. The supplementary sound in the VIP area and on both sides of the front court adopts NEXO classic style point source speaker PS15-R2. Can output peak 136dB sound pressure and has high speech clarity.

According to the feedback from the on-site engineer, "eight STM M28 projections are deployed left and right, making the sound reinforcement at the scene very uniform and very clear, so that the voice of the speaker on the stage can be clearly captured in both the first row and the last row. It also uses the power amplifier of NEXO's new product NXAMP mk2 to drive, so that the sound quality performance is excellent. With the experience of the previous session, we have full confidence in this arrangement. Although the number of participants affected by the epidemic has been reduced by half, we still deal with sound reinforcement very seriously and responsibly. The organizers are also very satisfied with this. "

The venue also held a sub-forum: innovation and Breakthrough of the Industrial Internet-- Digital enabling New Intelligence

The whole field communication equipment adopts Dante network connection and uses NEXO proprietary NEMO system management software. It is easy to jumper between the equipment and the instrument, divide the audio channel, adjust the volume and delay, and the operation is easy to understand.

The horn line and signal line are made of the famous German brand KLOTZ (Gauss). This wire has the characteristics of anti-interference, low transmission resistance and low sound quality loss.
