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.

Perfect for ball demolishers
Size: Medium
The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪

Chuckit medium rebound balls
Size: Medium
My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!

These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.
