稳定性高,频率响应宽,动态范围大,可任意改变频率。低音浑厚有力无
爆破声、中音饱满圆润、高音清晰柔和。
综合失真度为≤0.5%,麦克风尾管采用纳米材料制成,底座还加了硅胶,
更进一步起到抗震防摔的作用。适用于大型KTV等娱乐场所。
It has high stability, wide frequency response, wide dynamic range and can
change frequency arbitrarily. The bass is thick and powerful without blasting
sound, the baritone is full and mellow, and the treble is clear and soft.
The overall distortion is less than 0.5%. The microphone tail pipe is made of
nano-materials, and the base is added with silica gel, which further plays the
role of anti-seismic and anti-fall. Suitable for large KTV and other
entertainment places
