ULTRACOMPACT AND ULTRAPOWERFUL

Combining our Single Cycle Control™ and R.I.P.S.™ power supply technologies, MHD amplifiers deliver world-class, full-range fidelity and high-power output from an incredibly small package.

Features

  • High-fidelity Class-D design delivers superb sonics
  • Intelligently optimized for all the power - all the time
  • Full suite of studio-grade signal processing on board
  • Unique design adjusts operation to avoid thermal events
  • Exceeds international standards for salt fog and UV exposure

Single Cycle Control

Ground breaking technology applies output correction more than 400,000 times per second to deliver exceptional audio quality with reduced current draw and heat.

R.I.P.S. Technology

Regulated, Intelligent Power Supply is a tightly controlled design that maintains full power output from 1.5 to 4 ohms per channel and at any supply voltage from 11 to 14.5 volts.

Studio-Grade Signal Processing

Selectable 12 dB/octave (Butterworth) or steep 24 dB/octave (Linkwitz-Riley) filters with calibrated potentiometer to best integrate with subwoofers and component systems.

Differential-Balanced Inputs

A versatile design accepts speaker level signals without a line-output converter; it also delivers outstanding noise rejection while preventing alternator whine and other noises.

Advanced Rollback Protection

Innovative circuit design ensures that the amplifier will never shut down as a result of thermal overload and keeps the music playing, even under the most demanding conditions.

Built for the Elements

An all-aluminum, powder-coated housing with marine-grade hardware inhibits corrosion, and a watertight security cover protects all controls from the harshest of seasons.

Powerfully Neat

All MHD models share the same compact dimensions, making them far easier to place.

Realsink™ Chassis

The heat sink design requires no fans and permits stacking without losing cooling ability.

Fun for an active dog!
I have an Australian Shepherd that absolutely loves this auto rolling dog ball! The ball is hard, but covered in a rubber coating. It is still loud when it hits the floor, but that is to be expected. My dog has chased this as well as thrown this ball, and it is still working flawlessly! This ball is definitely durable! It is easy to charge, and provides hours of entertainment! The ball is a great size for a medium dog. I recommend it!

Auto-Rolling Dog Ball - loud with a mystery filling.
I got this to entertain my high energy dog and she does like it, but I don't. The ball is incredibly loud and doesn't move around nearly as much as I had hoped. When your dog picks it up, it turn their mouth into an amplifier making it louder. It bounces/vibrates around more than rolling. Which is not what I expected, but seems to be engaging enough for more dog (but that doesnt take much). What I really dislike is there is no way on the exterior to know what mode you are in and the inside is full of grease. To charge it and to see the lights to identify what mode it is involves opening it and touching the grease covered insides. The lights don't seem to match the instructions when trying to switch modes. The light is supposed to stay on for 3s. It doesn't for either mode and immediately cycles through other colors making it more confusing. The exterior seems durable enough for a moderate chewer and I like the color and texture. At $15, it seems like a fair price, but I can't recommend this at any price point. I don't feel comfortable letting my dogs play with toys that could easily expose them to an unidentified grease. Any greased components should be sealed. Not somewhere I have to touch for normal operation and potentially leak.

Gentle vibrations and rolling
My sweet old man dog didnt know what to think of this at first. We introduced it to him without turning it on at first, like a regular ball. That was fine, he was good with that and he liked to go chasing it (its heavy because its mechanical so I wouldnt throw it, a light toss/roll is how we started). After we played that way a while we turned it on. At first he was confused as to why his toy was chasing him. It mostly vibrates and bops around a bit. But then my pup started chasing it and kicking it around like a little soccer ball and he LOVED THAT. A charge lasts quite a while too and if he doesnt play with it in for a few minutes it goes to sleep so its not just bouncing constantly and driving me crazy. My pup likes it and it gives me a rest from the constant throwing so I'm happy!

Keeps My Dog Entertained for Hours!
This auto-rolling dog ball has been a total game changer for keeping my dog busy and active! The second I turned it on, my dog was instantly curious and started chasing it all over the house. It moves and rotates in a really fun, unpredictable way that keeps their attention much longer than regular toys. I love that it helps with boredom relief, especially on days when we can’t get outside as much. It’s perfect for indoor play but also works great outside too. The material feels durable and holds up well against chewing, which is a must for my pup. The USB rechargeable feature is super convenient—no constantly replacing batteries—and it holds a charge long enough for multiple play sessions. I also appreciate that it’s easy to clean and has some water resistance, so I don’t have to worry too much about slobber or a little outdoor use. Overall, this is a fun, interactive toy that actually keeps dogs engaged and moving. Highly recommend for anyone with an energetic or easily bored pup!

Great toy!
Pattern Name: Carrot
"Dog toys by Dole? The banana people??" Yep, me too. My dog loves this toy. The plastic piece is a great texture for chewing. The stuffy is small enough for most puppies and will grow to medium sized dogs. The green of the carrot crinkles and they both wash up good. The stuffy has been through the wash many times. Good quality, durable toys.
