Continuously-variable pattern condenser boundary button style microphone with remote polar control through digital signal processor (DSP). Variable polar pattern with remote control allows user to precisely adjust shape of pick-up pattern for best performance from within DSP. Utilizing two-conductor shielded cable (maximum length 2000 feet) between microphone head and DSP unit, polar pattern of microphone can be adjusted in real time without changing capsules, microphone positions, or inducing noise in audio chain. Special attention has been given to frequency response and sensitivity of microphone system while utilizing the variable-pattern control to precisely alter the shape of the pick-up pattern.
