From July 1 to 5, 2025, the 2025 Montreal International Jazz Festival (Festival International de Jazz de Montréal) in Canada was held as scheduled.

This festival is not only the largest music festival in Canada, but also one of the most influential jazz festivals in the world. It is the temple of jazz music; because countless masters have visited this festival, and some have even become resident musicians there. The most famous one is the trumpeter who is now over 70 years old---Clark Terry (Baidu Encyclopedia).

The 2025 Montreal Music Festival attracted more than 50,000 spectators. The atmosphere on the scene was still hot, and many European and American stars performed on stage.

What is different from the past is that the wireless transmission of the piano performance audio at this festival uses the digital UHF wireless system from China's GAODIMIC®.    

As we all know, the piano is the musical instrument with the widest range of sound, and its requirements for the sound quality of wireless transmission are extremely high. This time, two sets of GAODIMIC® and two sets of the latest DT228G-R wireless systems were used. Using 24bit, 48Khz sampling digital communication technology, the signal-to-noise ratio is as high as 123dB, the noise floor control reaches the monitoring level of 6uV, the entire sound range 20~20Hz interval attenuation <2dB, under 48V power supply, the battery life exceeds 12 hours.

The product worked stably throughout the entire activity, fully demonstrating its excellent performance and gaining attention and discussion from industry experts.
