Variable Polar Pattern / Boundary Series: 220VP The variable polar pattern boundary series 2220VP is a continuously-variable design condenser boundary button style microphone program with distant complete management through a Digital Indication Brand (DSP). The diverse complete design with handheld distant management or remote control system allows the user to accurately adjust the appearance of the pick-up design for best performance from within a DSP. Employing a two-conductor guarded cable (max length 2,000 feet) between the microphone head and the DSP unit, the complete design of the microphone can be altered instantly without changing medications, microphone roles, or causing noise in the audio cycle. Special attention has been given to the regularity response and understanding of the microphone program while with the variable-pattern management to accurately alter the appearance of the pick-up design.
