The 4x1 3G/HD/SD-SDI ASD Switcher with GPI Option and 12V Input from� Link Electronics �is a four-input video switcher that provides a convenient, low-cost way to route high definition and standard definition serial digital signals. This switcher is compatible with 270 Mb/s, 1.5 Gb/s, and 3 Gb/s serial digital interface signals. It can also be used for ASI and SMPTE 310M (19.4 Mb/s) signals, and the reclocking will be automatically be turned off. This switcher automatically equalizes the incoming SDI signal, compensating for greater than 1,000� of cable at 270 Mb/s, greater than 250� of cable at 1.485 Gb/s, and greater than 100� of cable at 2.97 Gb/s. The signal is then reclocked, with automatic rate detection for all popular data rates. The LEDs on the front panel indicate the data rate of the output video.

This multi-definition SDI 4x1 video switcher is capable of equalizing and reclocking all common serial digital signals, since it supports both standard and high definition signals. This makes it suitable for any application. The switcher�s versatility is illustrated by its ability to switch from SD to HD, SD to 3G, HD to 3G, and vice-versa. Another feature of this switcher is its ability to vertical interval switch when the inputs are synchronous. Vertical interval switching means that the switching takes place in the vertical interval of the video and therefore no glitch is seen in the active area of the video.

The 4x1 3G/HD/SD-SDI Switcher is a 1 RU chassis that is housed in the same case as the well-accepted 700 series. A black front panel distinguishes between the two series. Three 500 or 700 series can be mounted in the PRT-700 rack tray (sold separately).

The Natural Way to Better Sleep.
Color: Soft, Size: Standard(24"×16"×5.5"), Color: Soft, Size: Standard(24"×16"×5.5")
After trying out several latex over the years, the Talatex Talalay 100 stands out for its luxurious comfort, quality materials, and overall sleep experience. Made from 100% natural Talalay latex, it offers a perfect balance of softness and support. Comfort & Support: The Talalay latex feels incredibly buoyant yet plush. I found it especially beneficial for relieving neck pain. Temperature Regulation: One of the best aspects is its breathability. Latex naturally sleeps cooler than other foams. Eco-Friendliness: Another big plus is that it’s made from natural latex with no synthetic additives, making it a healthier and more environmentally friendly choice. It’s also hypoallergenic, which is great for allergy sufferers. Verdict: If you're looking for a premium latex sleep surface that delivers both comfort and longevity, the Talatex Talalay 100 is a solid investment. It’s not the cheapest option out there, but the quality and sleep experience justify the price.

Finally sleeping well again
Color: Soft, Size: Standard(24"×16"×5.5"), Color: Soft, Size: Standard(24"×16"×5.5")
Got the standard soft and the height is just right - perfect mix of plush and supportive. My neck pain is basically gone. Love that it stays cool through the night thanks to the little vent holes, and the Tencel cover feels super soft. Holds its shape really well too, no flattening. Packaging felt like a gift. Worth every penny.

Sleeping like a dream!
Size: Queen
We stayed at a Westin hotel recently and usually I don't sleep well when traveling but this overnight stay was heaven! I don't know what magic is in these pillows but they are a dream! I sleep in my side and these are perfect, I sleep the entire night with no back or neck issues. I've tried some expensive pillows from Sealy, Serta, etc, and nothing compared to the Westins! So glad these are available through the Westin Amazon store! And less expensive than anything else I've tried.

Not the same as hotel pillows.
Size: King
Ordered this pillow after staying at a Westin hotel. I should have returned it because it seemed different from the pillow at the hotel. It feels worn out and doesn’t keep its shape. Would not recommend.

Big high pillow, firmer than expected.
Size: Queen
This pillow could be a 5 for some people , and it was a 1 for us. Too high for our neck. Side sleepers. It’s probably very good for a back sleeper.
