5. Distant miking generally picks up less bass section with pressure gradient type of microphone cardioid figure 8 shotgun due to acoustic nature and lack of proximity effects Rich bass with distant miking can be recorded with pressure type of microphone Omni which performs the same frequency response with close or distant pick up Mounting the microphone Pressure gradient microphone is very sensitive to vibration Suitable shock mount for high performance microphone is necessary for extreme low noise recording Sturdy Stand can set the microphone excatly at the sweet spot and keep it there Choose heavy duty microphone stand for studio condenser microphone which weights much more than handle microphone Superlux provides wide range of microphone stands for various demands Big Foot Willie is specially developed for large condenser microphones that able to support 2 large microphones with stereo bracket for single point stereo recording Extension foot on all the E versions serve to mount heavy studio microphone in limit space live sound applications Maintainence Condenser microphone shall be kept in low humidity environment for best sound performance Store the condenser microphones in airconditioned room or dehumidifier to keep away form moisture Clean air is another important factor Keep away from smoking environment to avoid tar residuals Superlux marketing and sales Superlux Taiwan 886 2 26931323 Sales superlux
