RI-2 Main/Standby Audio/Video Relay Interface
The RI-2 allows instant selection of main or standby video and stereo audio signals. This selection may be made manually
from the front panel, or remotely via a switch or relay closure.
The RI-2 incorporates a multi-level 2 input x 1 output relay switcher
with channels for video, audio left, and audio right. Two auxiliary form-C relay contacts are also provided, for custom applications.
All contacts are gold plated to ensure excellent signal quality.
Remote selection may be accomplished with a remote
pushbutton, or by using a relay contact closure, such as those provided by the SD-2 Silence Detector or VSD-2 Video Sync
Detector. Using the RI-2 in conjunction with either of these two units allows automatic program switching in the event of audio or video
