This high performance live production system is engineered to support demanding multi‑camera environments where reliability, scale and precision are essential. Designed with a four bank architecture, it provides the switching depth required for complex broadcasts, multi‑layered show designs and fast paced event control. Its compact rack mounted frame integrates broadcast grade electronics with intuitive front panel controls and a large display that allows operators to monitor program output and adjust system settings directly from the unit. This design ensures dependable operation both in fixed installations and mobile production setups.
At the heart of this switcher are forty standards converted SDI inputs, enabling a wide variety of HD sources to be used simultaneously regardless of frame rate or format. Each input includes dedicated conversion and re‑sync, ensuring uniform signal timing and effortless integration of diverse cameras, graphics engines or playback devices. Twenty four SDI outputs provide extensive routing flexibility, supporting program feeds, auxiliary sends, monitoring points and integration with downstream devices. The system also offers multiple multiview outputs, allowing operators to observe a large number of sources in well organized layouts suited to complex productions.
Powerful internal processing tools expand creative possibilities. Four independent DVEs provide real time picture manipulation, enabling layered compositions or dynamic transitions. Sixteen advanced chroma keyers support virtual sets and high quality keying with precise edge control. Integrated SuperSource processors add further layering capability by combining multiple sources into a single composited scene, ideal for interviews, panel discussions or multi angle layouts. These features give producers a deep toolkit for building visually engaging productions without the need for external processors.
Audio handling is equally advanced through the built in Fairlight mixer, providing dynamics, equalisation and detailed control across all embedded and external audio channels. The system includes support for talkback to coordinate camera operators and technical staff, ensuring smooth communication during live broadcasts. Ethernet connectivity enables integration with software control panels or hardware interfaces, providing scalable operation based on the needs of each production. The quiet thermal design ensures stable performance even in noise sensitive control room environments.
This comprehensive switching platform combines scale, flexibility and precision to support high end broadcast production, professional event delivery or any situation that requires dependable multi camera control in full HD.

Not a fan of this one
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
I am not a fan of this product. As many of the reviews noted, the flavor is very strong. I was surprised it wasn't more minty. This is a very herbal concoction. It also tastes of the other very strong herbs, especially the rosemary. According to the instructions, this product should be used once a day for 30 seconds. I prefer a product I can use twice a day for 45 seconds to a minute.
My experience is that it takes 30 seconds just to crush it up enough to swish it around and I don't have enough saliva in the morning due to overnight dry mouth. I have to add a little water. The tablets never crush completely and leave a mess in the sink that has to be carefully rinsed away. If I use them more often, my mouth dries out too much and tastes like the tablets all day long. It's not a bad taste but I expect it to go away after a half-hour (or so). They are really chalky.
The container isn't bad, but doesn't pour 1 tablet out at a time. Meh. I don't like touching a bunch of them each time. There is a desiccant packet in with the tablets to protect them. I am not sure this would stay closed during travel or be allowed on a plane in carry-on. It should travel ok otherwise because it's not a liquid, but I haven't tried it. I will probably not buy this product again, but in all honesty, I have bought far worse products and been disappointed far more by them.

Its like they knew what I prayed for🙏🏽
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
Okay, let me start by saying I am a huge skeptic. I need to research things to the nine's and read legit reviews before I buy anything new.
I have had cavities from a very young age and receeding gumlines all my life. At age 50, I have gone all natural, got rid of everything toxic, and got really healthy. I have been listening to Dr. HUBERMAN podcast on you tube and found one he did on oral health. He gets very detailed about how to heal your oral health. He spoke specifically about hydroxyapetite and xylitol and their benefits.
I then started searching for mouthwashes with these ingredients because i am seriously concerned my teeth are going to fall out from these receeding gums. I have been told all my life there was nothing you can do. I knew in my gut that was a lie. I knew there had to be a way to heal our mouths naturally.
Then found BOKA. I got them. I tried them. I lOVE THEM! They are perfect! They are minty fresh, easy to use, makes my mouth feel clean and if they actually do heal my mouth....then awesome sauce!
I read all the reviews. I see the after taste. But, i think its a personal choice. I like the after taste. It tastes and feels like a clean mouth.
I feel the tinglyness. Yes. But I believe from my health and science background it is the mint, aloe, probiotics and everything else stimulating the skin and blood to start the regeneration of skin and mineral. Im happy to report back again in a month or so with outcome plus before and after photos👍🏽
