The AVS-816/HDA HD/SD-SDI Switcher with Analog Audio Follow from Link Electronics is a wide-bandwidth, video-audio vertical interval switcher designed for professional video applications. It supports both HD/SD-SDI video and analog audio. This unit features 16x16 switching functionality.

Digital and analog switching modules for both video and audio may be mixed in any combination to customize system functionality. Inputs are non-looping and offer outstanding return loss performance. For HD/SD digital applications, an optional analog monitoring output is available for analog audio. Audio and video break-away are selected by a single switch on the front panel. Dual LEDs on the source selection and follow switch indicate follow or breakaway. The analog audio inputs use standard 3-pin Weco connectors, designed for fast setup and disconnect.

The analog audio I/O features full transformer isolation to eliminate the possibility of ground loop interference. Switching is accomplished during the vertical interval by using the vertical sync derived from the video at the output stage. Similarly, digital audio switching takes place during the audio sample preamble. Up to 32 switchers can be controlled by the computer software.

This unit can be controlled with a serial data feed of RS-232 or RS-422/485, selectable by a simple internal DIP switch. A remote control panel is also separately available and uses the common RJ-11 modular connector along with the RS-485 interface standard. For automated system applications, an optional GPI interface is also available. The serial communication protocol is compatible with existing Link Electronics video and audio switchers and remote control panels. For integration into existing systems, the unit can be preset to respond to those instruction sets as well.

Very comfy
Size: X-Large, Color: White
I'm a size US Mens 14 with huge calves. Finding comfortable crew socks can be somewhat difficult. These are extremely comfortable, very stretchy and soft. Very worth the price.

I use these exclusively for when I'm hiking, cycling and walking ( exercising )
Size: X-Large, Color: Black
5.7.2019 Update: I have probably five packs of 3 of these socks. Can't explain it but recent pairs I've been using have lasted longer than previous two packs ( 6 socks )... So I'm going to get some more... They are my #1 go to sock for cycling, hiking, climbing, walking ( serious, training, speed, distance )... 10.30.19: I use these exclusively for when I'm hiking, cycling anqd walking ( exeqrcising )... They are light, comfortable, keep feet dry, cool & comfortable... They don't shift around on feet. They stay put once put on and running, climbing or cycling shoes are put on and laced up or ratched... I do a lot of hill climbing and also use on terrain where there's lots of long periods ( hours ) going up & hours going down... They don't appear to be very durable, get holes in toe or holes in heels, but 3 pack is relatively inexpensive so I continue to buy them. I do not use them for everyday casual wear because they would wear out very quickly compared to other similar sockets...

These socks are just OK. One arrived with a hole (easily sewn up, but kind of bummed about that). I prefer the Under Armour Resistor socks - they have support built into the socks that you actually can feel, and they were same price for 6 pairs!
