IDX : CW-7
Description
The CW-7 V-Mount Uncompressed Wireless HD/SD-SDI Transmission System is a transmitter and receiver set that allows you to send an HD/SD-SDI signal up to 328 ft with zero frame delay (less than 1 ms). It supports resolutions up to 1080i60/50 uncompressed in YCbCr 4:2:2 10-bit with two channels of embedded audio. Featuring four discreet channels, the system supports unicast operation, wherein multiple transmitters and receivers can utilize the available channels, and multicast operation where one transmitter can send to up to four receivers at the same time.
Available Configurations Include:
| CW-7 1 / 2 | HD-SDI/SD-SDI Uncompressed Wireless System w/ V-Mount; RX only |
| CW-7-3S (formerly CW-7-AB) | HD-SDI/SD-SDI Uncompressed Wireless System w/ 3-Stud Mount; |
| CW-7-3S 1/2 (formerly CW-7-AB 1/2) | HD-SDI/SD-SDI Uncompressed Wireless System w/ 3-Stud Mount; RX only |
