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
  • 3-Year Warranty

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.

Designed To Fit

Removable power and speaker plugs aid installations in tight spaces.

By far ... the SAFEST and most DURABLE bone for dogs that are hardy chewers!
Flavor Name: Beef, Size: Large
After searching high and low for a NON-TOXIC, DURABLE and truly SAFE dog bone, I finally found the large, beef-flavored, HARD version of the BetterBone for my year-plus-old rescue (Carolina Dog). 1 - it's made of all NATURAL food-grade materials (cellulose from plant cell walls) ... which means no nylon, no GMOs, and no other artificials materials so it doesn't event stain your flooring. My girl loves the tasty beef flavor. 2 - the wishbone DESIGN is genius because it gives her 3 ends to choose from (nubs v raised edges v smooth) and ample ways to stabilize it on the floor with her paws. 3 - it is uber DURABLE in standing up to the hardiest of chewers (my girl gnaws on hers daily and sometimes even multiple 10-minute sessions per day). It works great to clean and reduce tartar on her teeth. The biggest surprise was that it took 6 months for her to gnaw it down to a size that was no longer safe for her (i.e. a potential choking hazard), so I donated it to a lady with tiny dogs at the dog park. At $20 per large bone, it's a good value. 4 - and most importantly, ... it is super SAFE. It degrades in tiny little pieces that could not possibly cause a choking hazard, and being all natural (i.e. no nylon - which most bones do have), there is no worry if she does ingest some of the particles. They vacuum up with ease. The large bone weighs in at just over 12 ounces so it's kinda' heavy (9.25" long x 5" wide x 2" thick), but my 56 lb girl has no problem picking it up in her mouth before she hops up on the couch with me or into her bed. Thank you BetterBone for making a superior product that is healthy, safe and fun for my pup!

Best chew toy we have ever purchased.
Flavor Name: Classic, Size: Large
My moderately active 80lb Lab - Pit mix has been steadily working on this bone for over a year. He doesnt chew it every day but he does regularly chew it for 30 or more minutes at a time. He has only been chewing on the smooth end, and the only wear it shows is a slight thinning and some grooved tooth marks. It has not had any chunks come off, and has never developed any sharp edges that make it hard to play with. It has never smelled or gotten slimy. It has never triggered resource guarding with him, but he likes it enough that presenting it to him will often get him to settle down and chew when he is in a rambunctious mood. Its size and shape allows him to hold the textured Y end with his paws while chewing on the smooth end. All in all a fantastic toy!

Happy Doggo
Flavor Name: Beef, Size: Small
He immediately loved it. He doesn't take to bones quickly, but this one caught his eye. He's a 35 lb shepherd mix, and loves antlers, and chews pretty hard. I love that it doesn't smell, and havne't seen or noticed flakes. Overall would recommend.
