The 1800VP is a continuously-variable pattern condenser gooseneck microphone system with remote polar control. 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 manufactured 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.
