Get multiple audio sources in sync with your video, using the AD-300 Pro Audio Delay Box from Datavideo. This multifunction sound box offers 5 x input channels: a pair of RCAs, a pair of XLR-1/4" combo inputs, and an additional XLR-1/4" input on the front panel. The combo inputs feature mic- and line-level switches along with phantom power switches to provide +48V phantom power for condenser microphones. The unit offers a built-in mixer to route the incoming signals to a pair of stereo outputs with both balanced XLR and RCA connections to choose from. The 3.5mm front-panel headphone jack provides quick monitoring.

Each channel on the AD-300 offers a digital delay adjustable from 0 to 3000 ms, allowing you to get professional synchronization from multiple sources. In addition, each channel offers a compressor, limiter, expander, and gate, allowing you to tame audio levels and reduce noise for more professional-sounding results. High-pass and low-pass filters along with an 8-band EQ on every input provide precise control over frequency content, giving you additional audio-sculpting power.

Keeps them happy.
Style: Bunny
The interactive aspect is perfect: I squeak it to get her attention for fetch, she enjoys a solo dental chew session gnawing on the durable ears and body, and then we play tug-of-war with the long rope legs. It satisfies all her instincts in one cute, bunny-shaped package. The material is soft on her gums but tough enough to withstand serious chewing. Her teeth look cleaner and she's happily worn out. Total win!

Stuffless dog toy! Good buy 😊
Style: Bunny
My dog loves to tear her toys apart usually it’s to get all of the stuffing out. Lol so we decided to try some toys without the stuffing and this was definitely a good buy. She loves it. Very soft and she has not ruined it in almost 3 months. Very cute toy and happy with the company would buy again. Quality is very strong for a dog that tears toys up in a day. lol🤣

Tough Bunny
Style: Bunny
So far so good. We’ve been able to play tug-of-war with it several times and it’s not ripped apart. That’s why I gave it 5 stars. My dog has big teeth and a strong body. So this bunny is tough Only time will tell if it’s really worth the money

Hard to Destroy
Style: Bunny
My puppy hasn’t been able to destroy it yet. All other toys have only lasted about 10 minutes.
