CAD Astatic 1700VP Continuously-variable Condenser Overhead Microphone

The 1700VP is a continuously-variable pattern condenser overhead microphone system with remote polar control and carbon fiber miniature boom. 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 (max length 2,000 feet) between the microphone head and the pattern-control box, 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 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 are powder coated and made in the USA. The microphone head is painted matte black for an unobtrusive yet stylish appearance. The remote polar-pattern control box can be mounted in a single rack unit shelf with optional accessories.

Up to six control boxes can be mounted in one rack unit - 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 1700VP has been designed to resist interference from devices such as cell phones, two-way communication devices and lighting apparatus. Utilizing our RF Resistant Architecture, the 1700VP meets the stringent RF standards set by the European Union (see the specification section for more information).

The 1700VP comes complete with a 56" (142cm) Carbon fiber boom with the exclusive clutch rotation system, 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. The 1700VP is primarily designed for recording and sound reinforcement of choirs, instruments and ambient miking. The 1700VP can also be used for vocal pick-up in government, institutional and business applications. The optional miniature-boom allows the microphone system to be used on a free-standing microphone post.

The 1700VP microphone system is designed to shorten the list of products an audio designer needs to consider when hanging microphones are specified. The remote variable polar pattern control allows the installer or end user the ability to change polar patterns when installed or from scene to scene. Adjustments to the pick-up pattern can be done on the fly without costly lifts, ladders and capsules. Choose the 1700VP for your next overhead microphone install.
