Astatic 901VP Overview

The Astatic 901VP is a condenser boundary microphone with a continuously variable polar pattern. It is primarily designed to capture speech and voice for sound-reinforcement and teleconferencing applications in governmental, institutional, religious, and business settings.

When positioned on conference tables, desks, stage floors, or lecterns, the 901VP takes advantage of the boundary effect to capture a clear speech with reduced room ambience for intelligibility.

The continuously variable polar pattern allows the installer to precisely tailor the voice pickup pattern for the best performance depending on the application or environment.

Suitable for business applications, the 901VP is built to resist interference from devices such as cell phones and two-way communication devices. It also features a rugged metal body and shock-absorbing rubber bottom for easy placement on almost any flat surface.

The 901VP comes with a 30' detachable microphone cable that is terminated with a TA3F connector at one end and a 3-pin male XLR connector at the other. To operate, the mic requires 12, 24, or 48 V phantom power consuming 4mAh.

Continuously Variable Polar Pattern
  • The continuously variable polar pattern offers cardioid, omnidirectional, and figure-8 patterns with in-between variations
  • The polar pattern can be quickly changed using the built-in control located under the mic
Control Polar Pattern Remotely
  • The polar pattern can be changed remotely by setting the onboard variable pattern control to figure-8 and adding the CAD Audio VPC-1 remote variable pattern control box (available separately) between the microphone and audio mixer.
  • The pattern can also be electronically controlled by utilizing the 40-360 DSP cable and corresponding software (both available separately) with compatible digital-signal platforms.
Cut Unwanted Low Frequencies with High-Pass Filter
  • The integrated 80 Hz, 12 dB/octave high-pass filter removes unwanted low-frequency energy such as rumble, room ambience, and proximity noise to improve speech intelligibility

Astatic 901VP Reviews

Great mic for recording/streaming meetings

I’m a one man filmmaker and occasional videographer. I do a lot of different kinds of work, but sound quality is one area I take pride in. My normal approach is lavaliers, boom, and the occasional handheld microphone. Providing mics for more than 4 people is always a challenge, especially in low-budget situations. I was hired to stream 2 local government meetings to YouTube: 5 people at an L-shape table with 1-2 additional people in front of the table. Providing a wireless mic for everyone was not feasible and people like this generally don’t want to interact with tech. I remember using PZM mics in my days of AV Events, so I ended up finding these mics on sale for $50/ea. They looked good on paper but there were few reviews and no YouTube content. I decided to get 2 of these and try them out. They worked great, and the adjustable pickup pattern is a great option to have. Not as “present” as a lavalier or boom mic, but very impressive. People who project do better than people who don’t, but everyone can be heard. The omni pattern worked great for me since sound came from both sides of the table. As a rule of thumb, each mic is good for a 4ft radius, with voices sounding less present the farther you go from that. After the meeting I bought two more and I intend to make a detailed review/test video. You need phantom power for these. I ran them into a Sound Devices 442 mixer, then the output into my camera. They come with a decently long cable and a zipper bag.

Works well!

Use it for the children's message in church. The kids and the speaker are sitting on the altar steps. The unit can be moved as needed.
