"Very fast shipping. Good job!"


The Cadent features cutting edge, premium design that is bound to take your home theater to the next level. Its custom, milled aluminum housing and capacitive touch control face hides powerful 4x1 switching functionality, featuring 4k compatibility, picture-in-picture previews of sources, and split-second switching times.

Premium Design


We wanted the Cadent to be a home theater accessory that you don’t need to hide. It features a custom-designed aluminum housing with a rubber footing to keep it from sliding around, a custom designed remote (which also has an aluminum housing), and an easy-to-use capacitive touch face on both the Cadent and the included remote.


PolyView™ gives picture-in-picture previews, eliminating the guesswork from switching sources.

PolyView PiP Previews

PolyView™ takes the guesswork out of switching between your HDMI sources. Instead of being forced to remember which source is “HDMI 1,” the Cadent gives you a live picture-in-picture (PiP) preview of each source, making it easy to switch to the right one.


PolyShift™ can take switching times down to 1 second.

PolyShift Fast Switching Times

PolyShift™ takes away the long waits whenever you switch between sources. In most switch or matrix setups you are forced to stare at a blank screen for 15 seconds or more before you can finally start watching your content, PolyShift™ can take this down to 1 second, depending on the TV.

Pros: The idea was good...

Cons: Awful build quality, remote doesn't work well and the buttons on the unit itself are unresponsive 40% of the time. Shame.

Pros: Very pretty to look at. That's the one star.

Cons: Remote only works from <5' and not through doors. Must often press the button many times to get the input to switch. The remote vibrates confirming your press. It should really only vibrate to confirm signal received.Sometimes no matter how much I press the remote nothing happens and I have to press the buttons on the box. The killer though is the output signal drops in and out. You can be watching TV and the picture goes away, sound stays on. Sometimes the picture goes to a digital mess. Not a product ready to be released into the wild.

Other: I contacted support on all these issues and never heard back from them. Disappointing. Returning it.
