Crown MB3 AKG mini Boundary Pro Microphone

The Crown® MB-3 is a miniature boundary microphone for multi-miking applications such as teleconferencing, distance learning, boardrooms, courtrooms, and security applications. This low-profi le, circular mic permanently installs into a hole drilled in a table, lectern, or ceiling. Thanks to its supercardioid pickup pattern, the MB-3 greatly reduces ambient noise and pickup of room reverberation. The result is a clearer, more intelligible sound. On the bottom of the mic is a tubular power module with a 3-pin XLR-type output connector. It is powered by 12-48V phantom power, and has a low-impedance balanced mic-level output. How to Paint the Microphone 1. Using a small screwdriver, pry open one side of the base, then the other side (Fig. 5). 2. Remove the foam liner. 3. Wearing a dust mask, spray-paint the grille assembly. Be sure grille holes are not clogged. 4. Allow to completely dry. 5. Make sure the LED is properly aligned. 6. Carefully place the grille assembly over the base, and snap in place.

Recent Testimony

A-I Consolidated, Inc today
announced that it has
received a 2011 Gold,
2010 Silver & 2009 Silver Boeing
Performance Excellence Awards.
The Boeing Company issues
the award annually to recognize
suppliers who have achieved
superior performance.

Great place to order
from. I called twice to
check what I wanted and
the customer service was
some of the best I have come
across. They had to find out
some information on
product I was ordering
and had to call back.
Most places would take
all day if ever to call
back. A-I called back within
10 minutes with very
detailed information. Also their
price was the best and with
basic UPS ground shipping
I still received my package
in 2 days from placing order.
I will defiantly use A-I again.
