U-8000为专业演唱而设计,强调声音的饱和度和清晰度。
其内置有圆型滤音装置可有效抑制风噪和呼吸爆音,均匀
的心形指向模式能够有效地增强主声源,同时最大限度地
抑制背景噪音。无论是在室内还是户外演唱或演讲,会议
室和多功能厅等,都是专业人士始终如一的选择。
U-8000 is designed for professional singing, emphasizing sound
saturation and clarity. Its built-in circular sound filter can effectively
suppress wind noise and breathing explosion, and the uniform
heart-shaped pointing mode can effectively enhance the main sound
source, while minimizing background noise. Whether singing or
speaking indoors or outdoors, conference rooms and multi-function
halls are the consistent choice of professionals.
