The Astatic 901VP Condenser Boundary Microphoneis 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.

For Speech and Vocal Capture    Continuously Variable Polar Pattern    Resists Cell Phone Interference    30' TA3F to XLR Cable

• 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

• 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.

• 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

Q: 1. When muted, is there a light indicator?

A: Yes, the mute on/off status of the Senal MXBM-621/O MX Series Condenser Boundary Microphone is indicated by a dedicated LED.

Q: 2. Does this need a power module or phantom power? Tried hooking an older but similar AT boundary mic to a TASCAM DR-40 using the COXMMXF25 cable and would not work with or without phantom power on. Any help would be greatly appreciated and thank you in advance.

A: Yes it will need phantom power. The spec. sheet that came with the mic should tell you the voltage. If your mixer can't do phantom power there are products out there that will hook up to the mic then into the mixer that will do the job. Good luck.

Q: 3. In a larger area can multiple Omnidirectional mics be used without the mics be affected by signal interference with each other?

A: Unless you have some sort of physical separator like a barrier between the two microphones, you will not be able to keep the two MXBM-610/O Condenser microphones from picking up other sounds in the room as it is an Omnidirectional mic. A directional microphone would be much more appropriate for this kind of application if you are looking to cut down on bleed between mics.
