A surprisingly compact 12-channel amplifier with a new generation 12-channel DSP. 6 channels of RCA inputs, 12 high-level inputs, coax SPDIF input, optical TOSLINK input, Bluetooth AptX HD optional input, optional digital remote control for volume, sub level, preset selection, input selection, mute trigger. 12x50W RMS @ 4 Ohm output channels (at <1% THD+N), 12-channel RCA output, this DSP amp has it all. Perfect for 3-way active front + active rear amplification with an external subwoofer amplifier or 4 Ohm subwoofer on bridged channels 11 and 12 (yes, these are bridgeable even if undocumented). The powerful multichannel input EQ, time alignment and allpass filtering allows for proper OEM integration. A compact, dense multichannel DSP amplifier with very powerful DSP functionality for full integration in the modern multichannel active systems. Infinitely expandable to use high-end external amps via its 8V RCA outs on every channel - you can also use this DSP amp as a standalone DSP if need be. It's truly an universal all-in-one unit!
The DSP supports the following on every output channel:
- High pass, low pass and band pass crossovers (Linkwitz Riley, Bessel and Butterworth) up to 48 dB/oct
- 31 band fully parametric EQ with +/-15 dB correction, Q-value 0.3 to 15
- 1st and 2nd order Allpass filters with Q control and inversion (each of the 31 EQ bands can be switched to Allpass)
- Time delay up to 15 ms for time alignment, selectable in ms, cm or inches, optional linking of channel pairs
- Phase phase switching between 0 and 180 degrees
- Level correction from 0 to -40 dB, optional linking of channel pairs
- Fully functional input mixer, live mixing of inputs (2 inputs active in parallel), allows the set up of a differential rear fill
- Internal pink noise generator to test each individual output channel
The input of the DSP supports the following corrections on every input channel, including the COAX, TOSLINK and Bluetooth, separately:
- High pass, low pass and band pass crossovers (Linkwitz Riley, Bessel and Butterworth) up to 48 dB/oct
- 10 band fully parametric EQ with +/-15 dB correction, Q-value 0.3 to 15
- 1st and 2nd order Allpass filters with Q control and inversion (each of the 10 EQ bands can be switched to Allpass)
- Time delay up to 15 ms for time alignment, selectable in ms, cm or inches
- Phase phase switching between 0 and 180 degrees
- Level correction from 0 to -40 dB

Great for Tough chewers!
Size: Large, Color: Dinos Frills (Red)
My dog is a tough chewer and absolutely loves this toy! He was able to get a little stuffing out of the leg so far and it’s been about a week. This might sound like a short amount of time but it usually takes him under 15 mins to unstuff a large toy even if they are advertised for “tough chewers!” This is a very large size toy and would be good for any larger breed. He carries it around the house and constantly keeps his Dino with him. Since Ive found GoDog toys I’ve only been purchasing them because of their durability. I’ve tried Kong and Bark toys previously and they just do hold up long and are usually more expensive. This toy is a great value and dogs love them!

LOVE this brand. Have many of their styles. This is basically an unstuffed toy.
Size: Large, Color: Dinos Frills (Gray)
I have about 10 -12 different styles of the GoDog brand toys. It is like Xmas when my Malinois dogs get a new GoDog toy. Have loved this brand for many years and have some toys which have lasted 5-6 years -- minor "surgeries" stitch they back together -- until I retired them. They have never just worn out. Just to be clear:
THESE TOYS ARE NOT CHEW PROOF. NO STUFFED TOY IS CHEW PROOF.
However, this brand of stuffed toy is more chew proof than other brands. But if you are looking for a chew proof stuffed toy be advised -- IT DOES NOT EXIST!! No fabric is chew proof. Even if they invented such a fabric I would not want to ruin my dog's teeth by letting them try to chew through it. Protecting one's dog's teeth should be the highest priority.
If a dog can chew through a PLASTIC KENNEL and even METAL WIRE KENNELS (yes, it happens) then they can easily chew through a puffy, fluffy stuffed toy. The "Chew Guard Technology" language may be misleading to some customers who are disappointed in the brand. I defend the brand and have used it for many years. No, I don't get paid or get free toys.
Since I have had many styles within this brand and even have the pink version of this style I thought I knew what I was getting. This is basically a toy without stuffing which some people prefer. For whatever reasons my dogs prefer toys that are stuffed. Really stuffed with a firm density that they can sink their teeth into. So this toy will be OK. I can tell it will not be one of their beloved toys like some of the brand's other styles such as the purple brontosaurus. My fault for not reading more closely and assuming the grey version would be exactly like the pink version which is fully stuffed. If they get bored with these two I keep some of the Chew Guard toys stock piled.
BTW one can wash and dry these toys. Yes, eventually the squeakers suck up some water and die but one can replace the squeakers. Also on Amazon. So I am willing to replace the squeakers a few times in the life time of one of these toys to be able to wash and dry them occasionally. Usually takes a couple drying cycles to get the heavily stuffed toys dried completely.
If you have an aggressive chewer you may wish to look into Goughnuts dog toys or other hard rubber toys that are designed for aggressive chewers. Even then, with a determined dog, the Goughnuts toys can be chewed through. I think they offer a replacement guarantee. The other brand which has some toys of hard rubber is West Paw. An excellent brand that also offers a one time replacement. Bully Sticks are another option for chewers.
PLEASE, PLEASE, PLEASE stay away from the hard plastic chew toys like the Nyla Bones. Hard plastic toys will destroy your dog's teeth over time. I learned the hard way (no pun intended) and ruined one of my dog's teeth. Vet asked if I allowed my dog to chew ROCKS !!!!!! Every tooth was cracked or fractured. Not wishing to pull teeth I had to pay for some very expensive root canals and caps. Vet's advise: If you can't dent the toy or chew with your finger nail DO NOT offer to your dog. Good advise to follow. Even some of the Bully Sticks (Costco Brand) are so hard they can chip or fracture teeth.
Best for you and your dog.

Durable!
Size: 5 Inch, Color: Raccoon
Love these toys/brand! Our Beagle had to have stomach surgery from ratting something he shouldn’t have. Since then we hit this brand of toy because he really can’t destroy it! Great quality and highly recommend for dogs that like to chew!

Half gone in the first 45 minutes...
Size: 6 Inch, Color: Bone
our medium sized dog is an aggressive chewer but we expected mire than 3/4 of an hour before the bone's demise. Half gone quickly, heavy stitching included, so threw away the second half for fear of a blockage. Not safe, not durable, disappointing. Sorry, cannot recommend this one.
