The 1600VP 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.
