A half-cardioid boundary mic from AT!

The PRO 44 is a wide-range condenser microphone with a hemi-cardioid (half-space cardioid) polar pattern. It was designed for surface-mounted applications in high-quality sound reinforcement and other demanding sound pickup situations. Its low-profile design makes the PRO 44 ideal for use in applications where minimum visibility is required. A 25' (7.6 m) cable with TA3F and XLRM-type connectors is provided for use between the microphone and electronics input. The PRO 44 is great for any number of applications.

Audio-Technica PRO44 at a Glance:

Fixed-charged back plate construction
Easy to position
Rugged design

Fixed-charged back plate construction
Audio-Technica design engineers have utilized the newest low-mass technology in the quest for superior performance. The charge is now on the fixed back plate, rather than the moving element. With the A-T fixed-charge "back plate" construction, a gold-vaporized diaphragm just2 microns thick (about 0.000079") can be used. This reduces moving mass substantially, improving frequency response and transient response while reducing distortion.

Easy to position
Positioning a properly designed miniature unidirectional microphone centrally on a large, flat, unobstructed surface yields several distinct advantages. Directionality is increased by 3 dB, promoting enhanced gain before feedback and further suppression of ambient noise. Sensitivity is increased for improved signal-to-noise ratio. Phase distortion due to reflected sound energy from the boundary itself is eliminated.

Rugged design
The microphone element is enclosed in a rugged housing with a black finish. The rubber non-slip bottom pad minimizes mechanical coupling of surface vibrations to the microphone. The high sensitivity of the PRO 44 ensures useful output and an excellent match to most mixer, tape recorder and amplifier inputs. It will provide undistorted output even in sound fields as loud as 114 dB SPL.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:

2-year Total Confidence Coverage Warranty™!
Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!

I got 4 of these to record a round table style recording. They are very low profile and picked up everything very clear. I was able to place them under chairs out of sight, the people being recorded spoke in normal conversation tone and were able to be heard loud and clear in recording.

Beautiful song I love it.

The microphone is working perfectly. It's installed under the lid of an upright piano.

Used one of these for a floor tom, just placed it on the stage under the resonate head and it worked great.

Two great pieces here: the mic, which works better than you would think for the price. Even outdoors - tough setting- this is a win.

Also,the customer service was outstanding. There was a snafu with shipping but it was resolved quickly and professionally. This is a solid company to do business with.
