Some video and sound workers have carried out detailed and practical tests on several uhf ktv wireless microphones AY-URX7Ⅱ commonly used in daily work. The sound pickup of uhf ktv wireless microphone AY-URX7Ⅱ not only includes distance problems, but also includes sound quality problems such as distortion, noise, interference, and stability.

Test of uhf ktv wireless microphone AY-URX7Ⅱ:

The whole test was carried out in a TV production factory and mainly focused on the actual needs of TV sound work, including the performance indicators of the equipment, the working distance to simulate the actual working environment, the display of sound waveforms, and the subjective evaluation of sound quality. This paper only selects the distance test of group L and group S uhf ktv wireless microphone AY-URX7Ⅱ for discussion.

The test method of uhf ktv wireless microphone AY-URX7Ⅱ is roughly as follows: In order to place the above two sets of uhf ktv wireless microphone AY-URX7Ⅱ receiving devices at the same point, two recording engineers carry two different types of transmitters: the transmitter leads the microphone head or an external transmitter handheld microphone. Both move along the same prescribed route and continuously provide instructions and other voice information about the location on the move. The receiver group respectively sends the received signal to the two-way input of the mixing console, and outputs the recording console to the digital audio workstation by sub-tracking, for real-time sub-track recording, recording and on-site analysis.
