The AVS-815/HDA is an HD SD SDI video  
switcher with Analog audio follow. This unit is a  
wide band-width video/audio vertical interval  
switcher designed for the video professional in  
mind. It features compact modular design which  
allows it to handle HD SD SDI video and analog  
audio. The unit has sixteen channels of HD SD  
video and stereo audio. Digital and analog  
switching modules for both video and audio may  
be mixed in any combination for complete system  
flexibility. The 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.  
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. In a similar  
fashion, digital audio switching takes place during  
the audio sample preamble. Up to 32 switchers  
can be controlled by the computer software.  
The AVS-815/HDA may be controlled by a serial  
data feed of either RS-232 or RS-422/485  
interfacestandards, selectablebyasimpleinternal  
DIP switch. A remote control panel is also  
available which utilizes the common RJ-11  
modularconnectoralongwiththeRS-485interface  
standard. For automated system applications, an  
optional GPI interface is available.  
Audio and video break-away are selected by a  
single switch on the front panel. Dual LED’s on the  
source selection and follow switch indicate follow  
or break-away. The AVS-815/HDA allows the user  
to efficiently and economically route or delegate  
multiple video and audio signals.  
The serial communication protocol is compatible  
with existing Link video and audio switchers and  
remote control panels. For integration into existing  
systems, the AVS-816/HDA can be preset to  
respond to that instruction set as well.  
The analog audio inputs use standard 3-pin Weco  
connectors. The Weco 3-pin connectors are fast  
disconnect for ease of set-up.
