Description

AP4KAmplifiers 2x 1800w per channel Amplifier An impedance mode switch on the back panel of the amplifier allows the user to select full output power into either a two or four ohm load for maximum application flexibility. This means this compact two rack space amplifier can deliver up to 3600 watts of clean, pure power into either 4 or 8 ohm loads (bridged), making it a perfect solution for virtually any touring live sound, club system or installation.

Amplifiers 2x 1800w per channel Amplifier

An impedance mode switch on the back panel of the amplifier allows the user to select full output power into either a two or four ohm load for maximum application flexibility. This means this compact two rack space amplifier can deliver up to 3600 watts of clean, pure power into either 4 or 8 ohm loads (bridged), making it a perfect solution for virtually any touring live sound, club system or installation.

The internal signal path has been optimized and a toroidal transformer is used in the AP4K design - both serving to reduce hum and noise in practical real-world applications. It's three-tier Class-H design approaches efficiency normally associated with Class-D technology; yet provides the superior transient response and low distortion of the best analog designs.

Features

  • Delivers 1800 watts per channel into either 2 or 4 ohm load
    (3600 watts bridged into 4 or 8 ohms)
  • Proven Ultra Reliable Class-H Design
  • Easily Handles Reactive Phase Shifted Loads
  • Advanced Protection Schemes Including DC Current, Load, Thermal & Breaker Protection
  • Transparent User-Defeatable Peak Limiter Circuits
  • Soft Turn-On Circuit Protects Speakers and Prevents Nuisance Breaker Tripping During Power Up
  • Concise Front Panel Metering and Status LED's
  • Speakon™ and Binding Post Outputs
  • Balanced XLR and ¼-inch TRS Inputs
  • All-Steel Chassis Construction
  • Made in Canada

Name holds true.
Size: Large Triple
Just bought my second set of these.. first set lasted my healer almost 4 years and are still together but starting to split at the smaller seams so you can’t play as aggressive as my dog would like. We bought the second set and now she has her second wind! She loves tugging and I love knowing this toy will last a good while especially with an active dog!

My Aussie loves this bone!
This wishbone is so durable! My Australian shepherd is a big cheese and this is her go-to chew toy. It's a fave! She has spent HOURS chewing on this bone and it has held up super well. It has no smell but understand she can taste the flavor of it. I love having something she can chew on that is safe for her that she enjoys. Great value.

Durable, Great Value Dog Bone!
We’ve ordered several of these that have lasted for months, and my dogs are still working on them. Months. That alone feels like a small miracle. Normally, chews last about 10 minutes. Not this one. This thing is built like it trained for battle. It keeps them busy, satisfied, and focused on something that is actually meant to be chewed. And the best part? It’s way more affordable in the long run. Instead of constantly buying new toys, chews, or replacing destroyed shoes, this one just keeps going. Definitely worth every penny and then some. If you have determined chewers, this is the chew/bone you’ve been looking for.

Dog loves this
My dog absolutely loves the shape of these and will play with it for hours. The material is pretty durable too, though he is a big lab so over time chewed away the top nubs. Eventually tossed it at that point, but got great use out of it before. No bad smell and my pet really enjoys playing with it. It’s not too big either and is really easy to take with you on trips, etc. have bought multiple!

Dog liked it, chewing cat did not
My dog liked it, but I actually got it for my cat that insists on chewing on everything. However, he refused to chew on this toy. He sniffed it once and walked away. So, for dogs I guess it's a decent chewy...
