Shure ULXD4Q Overview

Part of the ULX-D wireless series, the Shure ULXD4Q houses 4 independent digital receivers in a rugged, single-rack unit with an internal power supply. Two Ethernet ports support Dante digital audio, while RF cascade ports allow for antenna signal distribution to another receiver unit. Audio summing enables the receiver to function as a 4-channel mixer.

The ULX-D Series simplifies the set up and management of large numbers of wireless systems. It is ideal for professional sound reinforcement applications in large live venues and houses of worship, as well as A/V installations in conference, educational, and corporate facilities. Compatible with a wide selection of Shure transmitters and mic capsules, it delivers pristine 24-bit/48 kHz digital audio, capturing every detail with clarity, accurate low end, and crisp transient response.

The ULX-D operates in the VHF band, utilizing Digital Predictive Switching Diversity to protect the transmission from interference, delivering rock-solid RF signal stability without audio artifacts. In Standard mode you can run up to 17 channels per 6 MHz TV channel, at a range up to 330'. Alternatively, the High-Density mode lets you run up to 47 channels per 6 MHz TV channel, at a maximum range of 98'. The system offers AES-256 encryption for security.

Each receiver module has its own audio and RF meters, 60 dB of gain control, and XLR output. A large LCD screen and intuitive controls let you quickly make adjustments, even in low-light situations. Additional features include automatic frequency scanning, IR sync, gain optimization to match any input source, and internal limiting to prevent clipping.

The Ethernet ports also allow multiple receivers to be easily networked together for simplified frequency coordination and deployment via Shure's Wireless Workbench software. In addition, the Channels Mobile App enables you to control the system remotely from an iOS device.

Very disappointed
Unfortunately I ended up being very disappointed with this purchase, after about two weeks of use, it just stopped performing. Not sure what happened but it just stopped releasing the ball and I don't know why, it had no flexibility left to it. I'm not doing a very good job of trying to explain why it quit working but suffice it to say, it became useless after a couple of weeks. Broke my neighbors dog's heart, lol.

Tough & durable, but relatively light for throwing
Pattern Name: Tug Frisbee, Size: Large
This is the second one of these that I've ordered although to be honest, the first one is still very much intact and it was bought when my 3-yr old Shepweiler was still a young, but growing, pup! Tough & durable, yet light enough to be thrown (& caught), without much effort. It can also be used as a tug toy, as my other pup, a pit/boxer/"Heinz57" mix, loves to use it as.

A favorite in our house!
Pattern Name: Ultra Ring, Size: Large, Pattern Name: Ultra Ring, Size: Large
~ Recommend if you have a dog who: is a heavy chewer/tugger, loves to chase squirrely things (it can have a wacky roll to it, which my dog thinks is so fun), gets their toys dirty or slobbery. My pup is 65 pound pitty mix - i'd definitely say this is for big dogs. Maybe medium (45+ pounds, ish?). Just my opinion, of course... but I think it's a bit thick/heavy for small pups to grab. ~ My pup LOVES this ring toy! I got this back in October - so it has been through the ringer. Atlas isn't usually a super heavy chewer, but with this toy she is. Not only does she love to play with it, she will even bring it to her bed to comfort chew (i think she likes the pressure on her back teeth... this rubbery material is SUPER sturdy but also has a little bit of "give" so I don't worry at all about her teeth). She loves to chase it / catch it on the roll. She brings it to me on the daily for play. Its good for tug, chase, or fetch. Perfect for the beach or any environment, really, as it's super easy to clean... so it comes with us everywhere. We will probably have this toy forever... there's not a single puncture mark yet. So, for me worth the cost 10x over.

Arguably bulletproof
Pattern Name: Tug Pull, Size: Large
All good. The gauge is slightly large which my dog, Magnum {66 lb American Stafordshire Terrier), struggles with - slightly. Not a big problem and I am thinking that if the guuge were smaller, Magnum would be able to chew through it and ruin the toy. Comfy grip. Center piece or grip works great also because Magnum likes to grip that which allows the 2 handles to be free for human pulling. Walmart has/had a similar item, but..........one end has tiny spikes meant for the dog to grip. My dog never liked that end, however, so I always got the ucomfortable knobly end and he got the smooth human end - hah ha. Too, Magnum chewed through two of these Walmart toys., I have seen Magnum chewing on this reviewed toy, but I am seeing zero damage. Walmart's toy is cheaper, but the lifetime guarantee on this Tuff Tug toy eliminartes any price advantage. Update 6 months later - the product appears to be bulletproof.....until it wasn't. Everyone on the dog park marveled at the item's amazing durability in terms of daily severe abuse AND my dog's preoccupation with gnawing on the toy. Not only does it hold up, but there are almost no discernable chew marks. All of that said, the toy did finally show some coming apart today (mid March '24 - bought Oct '23 with lots of daily chewing and tug of war abuse). Remarkably, with a good 30% of the item's thickness chewed through - it still stands up to severe and constant tug of war strain......like nothing ever happened! We joke at the dog park that tbe toy is made of Kryptonite. Yes, it's now damaged some, but I feel it is well worth the 20.00 price for the service it has delivered...
