If you do any kind of House of Worship production you have probably run into an issue with stage noise at some point in time especially if you are using a choir mic set up that has a wider pickup pattern. The over bleed can be anything from the minister talking to someone at the side of the stage to a baby in the first row. There is a solution though. You can use a continuously-variable pattern condenser microphone system to control the pickup pattern and dial the choir in.
One of the systems that Starin likes to recommend is from CAD Audio. The 1600VP, 1700VP, and 1800VP systems.
This series of continuously-variable pattern condenser microphone system comes with a remote polar control that 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.
CAD has given special attention 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. And the filter control is conveniently located on the control box so you don’t have to have a tech change it on stage.
We love the fact that this is a sturdy set up. The microphone head is made of commercial grade aluminum, the control box is made of hardened steel, and both manufactured in the USA. The microphone head and box are powder coated matte black for an unobtrusive yet stylish appearance.
Up to six control 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 communication devices and lighting apparatus. Utilizing CAD’s RF Resistant Architecture, the 1600VP / 1700VP / 1800VP meets the stringent RF standards set by the European Union.
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.
