Based on success story of Black Hole classic (BH-1) microphone we decide to upgrade our flagship to be perfect tool for day to day recording in world class studios.
Having improved sonic characteristics as BH-1, also BH-1s uses two separate back-to-back placed single diaphragm capsules which are manufactured using patented Golden drops technology. Every electronic component and capsule used in BH-1s is carefully hand selected and measured to achieve the best quality and sound. Therefore JZ offers life time warranty for every purchase of microphone.
Together with eye catching visual and sound improvements we added PAD switch with options of -10 and -20 db. Now you can use three directional characteristics (cardioid, omni, figure-8) and switchable pad for a wide range of applications.
