CM900VP Remote Variable Pattern Hanging Choir Microphone

The Astatic CM900VP is a professional hanging choir microphone designed for houses of worship, performance venues, and fixed installations where consistent coverage and musical balance are critical. Building on the tonal character and reliability of Astatic’s classic 900B choir microphone, the CM900VP adds continuously variable polar pattern control, allowing a single microphone to adapt to different choir sizes, stage layouts, and acoustical conditions. By adjusting the pickup pattern from wide omnidirectional coverage to tighter directional control, installers and engineers can optimize gain‑before‑feedback, improve articulation, and maintain a natural ensemble sound without relocating microphones or changing hardware.

What truly distinguishes the CM900VP is its remotely controlled polar‑pattern technology, a capability originally invented and patented by Astatic and first introduced in products such as the 1600VP. Using the VPC‑1 Variable Pattern Control box, the microphone’s polar pattern can be adjusted in real time via a standard XLR microphone cable—without accessing the microphone itself or interrupting a performance. This remote-control capability enables precise tuning during rehearsals or live services, making it possible to compensate instantly for changes in choir configuration, soloists stepping forward, or acoustical challenges in the room. The CM900VP represents a uniquely flexible solution that combines Astatic’s heritage in choir microphones with a proven, proprietary technology that remains unmatched in installed audio applications.
