This high performance Ultra HD live production system is built for demanding environments where extensive routing, advanced layering and broadcast precision are essential. Its four bank architecture provides deep switching flexibility, allowing operators to manage complex shows that require multiple simultaneous mixes, advanced transitions and layered effects. The compact rack mounted chassis includes an integrated control panel with an LCD display, enabling direct operation for setup or emergency switching, while offering immediate visual feedback of program output and system status. This design supports both studio installations and mobile production workflows where reliability and adaptability are critical.
A key strength of this system lies in its forty standards converted 12G SDI inputs. These connections support a wide range of Ultra HD formats and ensure that every source automatically matches the required frame rate and resolution. This allows cameras, graphics engines and playback devices to be used seamlessly, regardless of their native output. Twenty four dedicated 12G SDI outputs provide versatile routing to monitors, recorders, media servers and transmission paths. The unit also includes multiple multiview outputs, enabling operators to configure detailed monitoring layouts that display numerous sources simultaneously with clarity suited for Ultra HD workflows.
Advanced real time processing expands the creative potential of the system. Four independent DVEs allow repositioning, resizing and layering of video sources for dynamic picture compositions. Sixteen ATEM Advanced Chroma Keyers provide precise keying performance, ideal for virtual sets, green screen work and complex graphical overlays. Two SuperSource processors deliver additional multi‑layer compositing capabilities by combining multiple sources into arranged layouts, making them suitable for multi‑participant interviews, panel discussions and sophisticated on air designs. These internal tools reduce reliance on external hardware, keeping configurations efficient and integrated.
Professional audio features complement the video capabilities. The built in Fairlight mixer includes advanced processing such as compression, limiting and equalisation on each channel, ensuring well balanced sound across large productions. Integrated talkback allows communication with camera operators and crew through standard broadcast workflows. Ethernet connectivity supports software control surfaces or optional hardware panels, enabling flexible operation across large control rooms or production teams. Quiet thermal management ensures stable performance even during long broadcasts or in compact control environments.
This comprehensive Ultra HD system offers exceptional scale, precision and creative control, making it a strong foundation for major live productions, studio broadcasts and technically demanding event environments.

The easiest and best tooth brush!
Color: Pink (2-pack)
Ive tried several other dog tooth brushes for my 74 lbs Coonhound. This style and brand is the only one that is easy and works for us. It's easy to move your finger around and all sides of it have the cleaning nodules so no matter which way your finger turns, they are always touching her teeth. I like to try to open her mouth and get the inside of the mouth too. I loop my finger around her fangs. It is soft without harder parts so it doesn't make her pull away. This brush is perfect. It's a good quality and comes with a container for storage.

Total GAME CHANGER - incredibly effective toothbrush for dogs
Color: Clear (2-pack)
This silicon finger brush is incredibly easy to use - and so EFFECTIVE (more on that in the last paragraph this review). At first, it seemed a little hard to get on my finger but I simply got my finger wet first under the faucet and it slipped right on with virtually no effort. And once on, it's easy to take off but doesn't slip off accidentally when in use - so - perfect! Quick & simply to clean - rinses off in the sink in seconds, and ready to use the next time. And, my dog not only lets me clean her teeth - she actually like it (this from a dog who used to hate it when I would try to brush her teeth with a regular doggy toothbrush).
This silicon "brush" is incredibly maneuverable - way more so than standard dog toothbrushes or regular finger brushes. So much so it makes it super easy to not only get those normally impossible to reach back molars - AND - even the back sides of the teeth! With a normal dog tooth brush (or finger brush) my dog's clamping down made that impossible. Now, it's not only possible - it's easy!
Our dog's canine teeth had build-up but it was not until I pulled her gums back and looked at her back molars that I saw how bad things had gotten - and we have a young dog! Her back molars not only had build-up but some appeared to be stained a tea colored brown that did not come off with my fingernail. It was pretty disheartening and I felt terrible. How could this happen so quickly? The vet said it was plaque (and not yet tartar) and that it wasn't bad enough to warrant a professional cleaning - yet - but that I needed to do a better job brushing. He said: "I can see exactly where your brushing stops" (referring to the condition on the back molars which I had not been able to do with a regular brush as my dog just wasn't having it).
Tips: here's what's working for us. Instead of squeezing out a pea sized blog of tooth paste onto this brush, I put a tiny dab - that it's - on the very tip of the brush and focus my efforts on two of our dog's worst teeth on one side - on top and then on the bottom. Then I put another small dab and repeat on the other side of her mouth with 4 teeth on that side. Then, I use another small dab and focus work on another group of teeth. All totaled, I'm using maybe 4 to 6 very small dabs of dog toothpaste, probably half the size of pea collectively, perhaps less. That's it. However much you choose to use is up to you - be sure and use an amount that's safe and effective for your dog.
Effectiveness: this works and it works well! In just 3 days using the same vanilla flavored enzymatic toothpaste by CET I was seeing improvement. By day 7, that improvement was so obvious I was actually surprised by how much better they looked. It's now been a little over two weeks and they are looking considerably better! Conservatively, I'm thinking a 50% improvement. Not bad for just 2 weeks, right? I'm actually think I'm going to be able to completely reverse things - we'll see. I'll try and update this review again in a few weeks and let you know how it's looking but in the meantime, I am absolutely thrilled with this brush. I paid $16 and it came 2 in a pack) and the first (and only one) I've been using still looks brand new after it's rinsed off. All in all - this brush is a game changer! I can now brush our dogs back teeth and even the back sides of her teeth, all in less than a couple minutes a day.

Great dog toothbrush!
Color: Blue (2-pack)
I’ve been using this product for a year now, and it’s been working great. When paired with vanilla mint enzymatic toothpaste, it effectively cleans my Pomsky’s teeth, including the back teeth. As a result, my fur baby’s teeth remain as white as ever!
