Designed for commercial and industrial use, the CSMA 2120 Commercial Series Mixer/Amplifier from JBL is a mixer/amplifier with eight mixer-channel inputs and two output channels. It's capable of reaching 120W of peak power with 15W per channel. The unit's front panel sports volume controls for each channel, as well as two master volume adjustment knobs, two sets of bass and treble controls, and a power switch. The volume controls are illuminated so they can be seen and operated in darkened environments.

The amplifier, capable of driving both eight and four Ohm loads, can be used with 70V and 100V distributed audio systems without the need for a separate transformer. On its back panel you'll find euroblock connections for mic/line inputs, as well as unbalanced RCA inputs, speaker connections, dip switches for input routing, and more. The unit is also equipped with two RJ45 connectors for use with JBL CSR-V in-wall volume controls (available separately).

This Commercial Series mixer/amplifier boasts such features as voice activating ducking (useful for paging over background music), priority muting for channels one and five, and a sleep mode which automatically powers down the unit when no audible signal has been received for longer than 30 minutes. Also, with two auxiliary outputs, you may connect to an additional amplifier, though the master volume and tone controls will have no bearing on the resulting signal.

Wonderful
Size: 9 Inch, Color: Red
Just bought my second one for my German shepherd. 1st one I bought a year ago. She managed to pop it within a few days. She still was able to play with it by grabbing ahold of the straps. Takes it everywhere. We call it her tether ball. Should've seen her when we got the new one out of the box. Hasn't left it alone since.

Keeps him busy. Puppy proof
Size: 6 Inch, Color: Independence Day
Thankfully I bought 2. One of the pumps broke as I was trying to blow up. That is the reason i did not give then 5 stats. This is a great toy for my puppy. Keeps him entertained and is pretty sturdy.

Great for dog self play
Size: 6 Inch, Color: Red, Size: 6 Inch, Color: Red
So much fun for my puppy. Easy to grab and throw for him to play alone. Durable for a medium dog. This is his favorite toy. I also bought one for my friends cattle dog puppy who went bonkers with it. Yet her dog liked to chew the tags off. So I wouldn’t recommend for chewers.

Fun to fetch
Size: 5 Inch, Color: Red, Size: 5 Inch, Color: Red
Perfect size for my 1 yr old Cavapoo that is ball obsessed. This ball is fun to toss around in the yard to exercise and wear out my energetic boy. Perfect for after my work day when I don’t have the energy to match his energy level. He gets to run and chase and I can enjoy his playtime too. Overall the ball is durable and I have confidence it will last for a very long time. We have 2 sizes, small and medium, for my 30 pound athletic pup. He enjoys both equally.

Dog loves them
Size: 6 Inch, Color: Independence Day
My dog loved the first ball I got her, so I got her a second one. Both hhavr been very durable (she likes to puncture things with her teeth). I left each ball slightly deflated, so they were still firm, but she could bite them without issues. She has not punctured either ball yet. I did have to watch her because she started trying to chew the tabs off because she was bored. She has not chewed one off, just started thinking about it, and did a tiny bit of damage to one tab. She loves these balls. We have played tug of wat with them too, so yhe tabs are sturdy, and so is the ball. The dog did not care what collar she got, so I grabbed the least expensive one, and the 6 inch. She is a medium sized dog with razor teeth, and these work great.
