The AVS-816/HDD is an HD SD SDI video
switcher with AES 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 video and AES audio. The unit
has sixteen channels of video and AES audio.
Digital and analog switching modules for both
video and audio may be mixed in any combination
forcompletesystemflexibility.Theinputsarenon-
looping and offer outstanding return loss
performance.
Audio and video break-away are selected by a
singleswitchonthefrontpanel.DualLED’s on the
source selection and follow switch indicate follow
orbreak-away.TheAVS-816/HDDallowstheuser
to efficiently and economically route or delegate
multiple video and audio signals.
The AES audio inputs use standard BNC
connectors. The Weco 3-pin connectors may be
ordered as an option for balanced audio.

The digital audio I/O features full transformer
isolation to eliminate the possibility of ground loop
interference.Switchingisaccomplishedduringthe
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-816/HDD 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.
The serial communication protocol is compatible
with existing Link video and audio switchers and
remotecontrol panels. For integrationintoexisting
systems , the AVS-816/HDD can be preset to
respond to that instruction set as well.
