The 901VP is a continuously-variable polar pattern condenser boundary microphone. Special attention has been taken to design the 901VP 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 all metal body and shock absorbing rubber bottom make for easy placement on almost any surface.
The 1600VP / 1700VP / 1800VP is a continuously-variable pattern condenser microphone system with remote polar control (patent pending). The variable polar pattern with remote control allows the user to precisely adjust the shape of the pick-up pattern for best performance from a remote location. Utilizing a two-conductor shielded cable (maximum length 2,000 feet) between the microphone head and the pattern-control box (VPC-1), the user can adjust the polar pattern in real time without changing capsules, microphone positions, or inducing noise in the audio chain.
Special attention has been given to the frequency response and sensitivity of the microphone system while utilizing the variable-pattern control to precisely alter the shape of the pick-up pattern. The large- diameter, low-noise elements produce a frequency response of 40Hz to 20KHz with a selectable, recessed 80Hz, 12dB/octave high-pass filter that removes unwanted low-frequency energy when engaged. The filter control is conveniently located on the control box.
The microphone head is made of commercial grade aluminum, the control box is made of hardened steel, both manufactured in the USA. The microphone head and box are powder coated matte black for an unobtrusive yet stylish appearance. Up to six con- trol boxes can be mounted in one rack unit shelf – Astatic RU1. The polar- pattern dial is positioned for easy adjustment on the fly and can be secured with a single Flat Style blank panel when rack mounted.
The 1600VP / 1700VP / 1800VP is designed to resist interference from devices such as cell phones, two-way communi- cation devices and lighting apparatus. Utilizing our RF Resistant Architecture, the 1600VP / 1700VP / 1800VP meets the stringent RF standards set by the European Union (see the specification section for more information).
The system comes complete with microphone head, VPC -1 control box, 30′ (9.1m) of two-conductor shielded cable terminated with a TA3F-type connector and 3-pin XLRM -type connector. Also included with the microphone system is a 3-pin XLRF-type connector on a stainless steel duplex wall plate.
