Shure SM81-LC Cardioid Condenser Instrument Microphone for Guitar, Piano, and...The Shure SM81 is a high quality, unidirectional condensermicrophone designed for studio recording, broadcasting, and soundreinforcement. Its wide frequency response, low noise characteristics, and lowRF susceptibility have made it a standard for applications involving acousticinstruments, especially guitar, piano, and cymbals.

The Shure SM81 is a high-quality, unidirectional condensermicrophone designed for studio recording, broadcasting, and soundreinforcement. Its wide frequency response, low noise characteristics, and lowRF susceptibility have made it a standard for applications involving acousticinstruments, especially guitar, piano, and cymbals. POWER REQUIREMENTS NOTE:This microphone requires phantom power and performs best with a 48 Vdc supply(IEC-61938). However, it will operate with slightly decreased headroom andsensitivity with supplies as low as 11 Vdc. Most modern mixers provide phantompower. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS. Built to withstand the rigors of regular stage and studio use, theShure SM81 unidirectional condenser microphone is a great choice for studiorecording, broadcasting, and sound reinforcement. Its wide frequency response,low noise characteristics, and low RF susceptibility make it a perfect matchfor applications involving acoustic instruments, especially guitar, piano, andcymbals. Ruggedly constructed, the SM81 operates on phantom power and performsover a wide range of temperatures and humidity conditions. It comes with aswivel adapter, attenuator-switch lock, foam windscreen, and case for carryingand storage. Key Features Frequency response.

Too big for puppies
Color: A.Green+Orange
The balls were a bit too big for my 6 month chihuahuas:/ they are as big as a tennis ball so puppies didn’t like nor play with them

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
