Equipped with a newly developed φ19.2 large diameter diaphragm,
40 Series new stick-type instrument microphone.
● 40 series new stick-type instrument microphone equipped with a newly developed φ19.2 large diameter diaphragm.
● Adopts a newly developed “double wave diaphragm (PAT.P.)”. Achieves sensitivity characteristics that transcend class and ultra-low noise levels.
● The brushed up mid and low frequency characteristics stand up well and naturally express hardware, pianos, acoustic guitars, etc.
● Standard equipment includes an 80Hz/12dB/oct. high pass filter that effectively cuts dark noise, and a -10dB pad switch that is useful at any site.
● Strengthen RF countermeasures against mobile phones, wireless intercoms, and radio waves. It greatly reduces noise and eliminates problems at sites with poor environments.
