The DL210 NET D 2.0 hearing loop amplifier maximizes modern amplifier technology. Its network-control capability provides seamless, remote system set-up, operation, and monitoring of the induction loop system via a laptop or tablet. DSP audio processing offers flexible, powerful software control of mixing, equalization, compression, and more. Powerful Class D pulse-width amplifier maximizes the efficiency of the unit. The Dante™ input provides integration with existing Dante™ devices and remote network management.

This assistive listening system’s design offers a dual 12 A rms loop output for dual loop or phased array configuration. A 70-100 V input connects to a distributed speaker/paging system, ensuring announcements are heard by hearing aid users.

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Solid interactive automatic vibrating dog ball toy
Color: Blue, Color: Blue
Picked up this ITEHZTO interactive automatic vibrating dog ball for our pup and it’s a fun, engaging toy that keeps her entertained. It’s rechargeable with USB, motion-activated, and has a good vibrating/rolling action that gets her chasing and playing on her own. The durable build seems like it can handle some rough play, and it’s a nice size for indoor or outdoor use. It lights up or vibrates when activated which adds extra excitement, especially during evening playtime. Battery life is decent and recharges quickly. Great for when she needs mental and physical stimulation without me having to throw a ball constantly. Overall a solid interactive dog toy that does a great job keeping active dogs busy. Good value if your dog loves chasing moving/vibrating toys!
