JLCooper MLA-XLR - 1 Input / 1 Output MIDI Line AmplifierThe MLA XLR from JL Cooper is designed to act as a single channel, bi directional, long distance amplifier or driver for MIDI signals. While the normal MIDI protocol specifies a maximum cable distance of about 50 feet, this is sometimes not sufficient for some installations.

The MLA-XLR from JL Cooper is designed to act as a single channel, bi-directional, long distance amplifier or driver for MIDI signals. While the normal MIDI protocol specifies a maximum cable distance of about 50 feet, this is sometimes not sufficient for some installations.

The MLA-XLR takes a MIDI input and converts it to a balanced, differential signal using the RS-422 specification. At the other end, another MLA-XLR detects the signal using a sensitive receiver that has a high degree of noise immunity. Connecting the two MLA-XLRs are two standard, shielded, twisted pair microphone cables.

The combination of a low impedance, differential driver coupled with a sensitive differential receiver signal lends itself to long distance, error free installations and making it possible to send a MIDI signal through 1000 feet of cable or more. The MLA-XLR is compatible with the JLCooper MLA-1 and MLA10.

Note: Installation requires a MIDI Line Amplifier at either end

My Dog's Favorite Toy
When my small poodle mix was rehomed to me, he came with many toys. One of them was this latex squeaky toy. It is his absolute favorite toy and I've bought several more so I have them on hand if anything happens to the original Polka-dot Pig. Amazingly, my dog is a chewer but has never used this toy to chew on - only to play with. He will sometimes play by himself with it, but usually it's a robust game of indoor fetch (he doesn't fetch outside, go figure). An added bonus is that with the inhale of air, the toy makes a different squeak that inspires my dog to howl. It's a riot. People should know that this toy is LOUD and the smaller size does not grunt, it squeaks. Another bonus is that it squeaks with the slightest touch - the dog doesn't have to find the squeaker in the toy, the whole toy is the squeaker. Oh, and it also bounces erratically, which is fun for the dog. This household will never be without Polka-dot Pig.

Product is not what was advertised!
Umm…..SERIOUSLY??!! This dog toy was supposed to be big enough for an Australian Shepherd dog to be able to play with. This dog toy was also supposed to have a pig grunt, just like all of the other pigs that are just like it. It was supposed to come in various colors, and multiple pigs-(from what I saw in the picture advertisement.) The pig was the size of a regular Altoids tinbox. This toy pig did not have a grunt, when it gets squeezed; but, it had one of the most annoying high-pitched squeaking sounds! There was only one small toy pig, and it only came in yellow. Where are the other five pigs that are supposed to go with this, if that’s what the picture advertises? How come I don’t get to choose the color of the pig, but I’m left at your mercy on what color you’re going to send me. I still have this toy pig, still wrapped up in the original plastic wrap. There is no way that I am going to give this little toy pig to this big Australian Shepherd dog, because he would tear it up within 10 seconds. I still have the toy pig, and I want to send it back for a refund. This advertiser was very misleading, and they need to pull their ad off of the site. I am very disappointed in what I received!!

Will not last long, but when on sale, decent for a few seconds
Gave this to my dog once it got delivered. It's a cute little toy and my dog loved it. Loved it SOO much that he destroyed it in about 30 seconds. It only really lasted that long because he was trotting around the house squeaking it and then decided to destroy it. My dog loved it. It's super soft and pretty small. I'd buy this again for cheap, definitely not for full price.

Squeaker broke after 3 days
I have a Boston terrier that destroys every toy! Thought we would try this one out. He really liked it. Squeaker was really good. Was is the key word after 3 days. Yes he broke it. But the rest of it is standing up so we'll have to see. I got it on sale for only $2. I wouldn't pay much more for it otherwise
