Description

Audio-Technica Miniature Cardioid Condenser Boundary Microphone w/TB3-to-XLR Output (Black)Audio Technica has taken its low profile ES947C cardioid boundary microphone and given it an even smaller footprint, making it a great choice for installations with limited space or where a very clean, inconspicuous look is desired. The miniature ES947C TB3 still gives you the same clear, highly intelligible audio of its larger sibling, mounting unobtrusively in tabletops, ceilings or panels for conferencing, recording, monitoring and other demanding

Audio-Technica has taken its low-profile ES947C cardioid boundary microphone and given it an even smaller footprint, making it a great choice for installations with limited space or where a very clean, inconspicuous look is desired. The miniature ES947C/TB3 still gives you the same clear, highly intelligible audio of its larger sibling, mounting unobtrusively in tabletops, ceilings or panels for conferencing, recording, monitoring and other demanding sound pickup applications.

Protected by a rugged all-metal case with a two-layer steel mesh grille, the microphone’s cardioid polar pattern affords a 120° pickup angle, while its UniGuard® RFI-shielding technology provides outstanding rejection of radio frequency interference (RFI).

The ES947C/TB3 is equipped with a self-contained power module with a TB3M (mini-XLR) output connector, eliminating the need for an external power module. It also comes with a TA3F-to-XLR cable, allowing for installation with standard XLR inputs. The microphone is available in black (ES947C/TB3) and white (ES947WC/TB3), and comes with a pair of rubber isolators for optional mechanical isolation from the mounting surface.

Easy to grab and throw!

Our puppy loves this ball, although it gets stuck on her teeth sometimes, but she gets it off just fine! Easy to play and throw. She has a blast catching it, too!

Keeps my dog happy
Size: Medium
This is a fun toy for our cavalier. It's pretty versatile in how you can use it, which I like because it allows me to change things up to keep my dog engaged. He's also an aggressive chewer and he hasn't destroyed it.

Good size and great bounce!
Size: Small
My 1 1/2 year old Cavapoo loves this toy. Very light weight ball that bounces off her paws when she reaches for it and then having to chase it further. Then she charges back with it for another chase when I throw it again.

THE BEST INDESTRUCTIBLE BALL
Size: Medium, Size: Medium
I bought this ball 6 months ago and feel obligated to come back all these months later to say how great it is! My Frenchie has killed every toy he’s ever had but not this ball! He absolutely loves this ball. It’s lightweight and can be used for both indoor and outdoor play and still looks brand new.
