Variable Polar Pattern Boundary Microphone with Programmable Switch, LED and Logic Interface

The 930VPL is a continuously-variable polar pattern condenser boundary microphone with a programmable membrane switch, LED and logic interface. Special attention has been taken to design the 930VPL to resist interference from devices such as cell phones and two-way communication devices. The integral 80Hz, 12dB/octave high-pass filter removes unwanted low-frequency energy to improve intelligibility. The dual output-connector design allows the cable to exit the rear or the underside of the microphone. When mounted on a flat surface, the 930VPL will take advantage of the "boundary effect" signal-to-noise ratio increase. The 930VPL comes with 30 feet [9.1m] of detachable microphone cable that is terminated with a standard 3-pin XLRM-type connector. The 930VPL features logic I/O functions that can be utilized with automatic mixers, teleconferencing systems and control systems. The logic input can remotely control the LED as well as the membrane-switch activation. The membrane switch working with or bypassing the microphone's mute activates the logic output. Bypassing mute is particularly useful with teleconferencing systems that mute the microphones after the echo-cancellation block. The exact mode of operation can be set with the dip-switch on the underside of the microphone. The 930VPL has a continuously-variable polar pattern so it can shorten the list of products an audio system designer needs to consider when boundary condenser microphones are specified. The installer can precisely tailor the polar pattern for the best performance depending upon the application or environment. The 930VPL is primarily designed for speech and vocal pickup in governmental, institutional, religious and business applications.
