The BSS Audio BLU-50 is a 4x4 signal processor with built-in BLU link that provides 48 channels of low-latency, fault-tolerant digital audio. The BLU-50 is configured, controlled, and monitored for HiQnet Audio Architect and is compatible with other members of the Soundweb London family.

The 48 channels of BLU link bus represents channels 1-48 of a larger 256 channel BLU link bus when integrated with other BLU link devices such as the BLU-800, BLU-320, BLU-160, BLU-120, BLU-BIB, and BLU-BOB devices. Up to 60 BLU link compatible devices can share channels on a single bus. As with other Soundweb London devices, 12 Control Inputs, 6 Logic Outputs, and an RS-232 port allow the BLU-50 to be integrated with other compatible devices.

The 1/2 rack processor offers a fixed configuration of four inputs and four outputs, configurable signal processing, logic processing, and BLU link. The device can be powered via POE or from the included 12 VDC power adapter. The analog inputs of the BLU-50 provide software configurable gain in 6 dB increments up to +48 dB per channel. Software selectable phantom power is available per channel. The front panel provides LED indicators for phantom power, signal present, and clip information.

Great value, durable, enriching
Size: Large (5" x 3.25" x 9")
$5 for the large size for our 15lb chiweenie mix was PERFECT. Her emotional support chew toy got destroyed and I wanted something I felt safe leaving in her kennel while I was out. She anxiously chews. Bought this to try out and she took a bit to get into it, but now she loves it. Probably could’ve gone with a smaller size, but oh well. We put treats inside and smear peanut butter or wet food on the dumbbell like ends for enrichment. So far has held up over 3 weeks.

A good choice
Size: Large (5" x 3.25" x 9")
Initially I put this toy in my save-for-later on Amazon. As I was perusing through one morning I noticed that it had been reduced so, I ordered it. It arrived promptly, was well packaged, and has been a good addition to my Doberman's toy box. It has not been chosen as the ultimate favorite, but he likes enough to select it, carry it around, and chew on it. To us there is no unpleasant odor. It is good solid rubber and despite all of his chewing maneuvers, there are not holes, marks, or bits of the ball where they should not be. He carries the toy in his mouth in the middle of the toy, but likes to lie on the floor, hold one ball end in his paws and chew on the other. Overall, I would give this a grade of a good, solid, reliable dog toy. I cannot address suction power, because I am not sure what is meant by that in a toy that is shaped like an old fashioned dumb bell. Top 3 Likes: -Durable rubber chew toy for large dog that is easily carried -Bright color making it easily visible -No offensive odors Top 3 Dislikes: -Serviceable toy, not a favorite -Could be chewed into little pieces by a very aggressive chewer (mine is not) -Poor at dispensing treats; they fall right out with no challenge

Wish I could give more stars after 8 months 🙌🏼
Size: Large (5" x 3.25" x 9")
I purchased this in June and I've come back in January to leave a review. This was the first toy I bought my dog I had it delivered while she was still in the shelter and it has lasted longer than any other toy. Not only can she not destroy it when she's actively trying but she still loves it she plays with it all the time I don't even need to put treats in it she just enjoys the texture. This toy was such a win. I have wasted so much money since then on other toys that say their indestructible and turn up in pieces. I wish I could give it more stars

Dog loves it! For tough chewers for sure
Size: Medium/Large, Color: Dog Ness Monster - Large, Size: Medium/Large, Color: Dog Ness Monster - Large
Dog absolutely loves it, he’s super rough on all of his toys they usually last about 10 minutes bore they are torn to shreds. It’s lasting through his chewing so I’m happy. It’s also super cute.
