OVERVIEW
The Video Sync Sensor (VSS2) is equipped with two independent
signal detection channels. When a signal is present, each
detection channel initiates a logic-level output, and dual video
jacks for each channel allow loop-through operation. The VSS2
is an ideal power sensor for DVDs and other video sources, or to
provide a warning on loss of audio, video or RGB signal.
COMMON APPLICATION
Use the VSS2 to monitor the true power status of a VCR, tuner
or satellite receiver and track the video output of each source,
sending a logic signal to an input port. The output can also be
used to control other AMX closure-driven peripherals, such as the
PC1 Power Controller.
FEATURES
- Detects presence of signal from 1 kHz to greater than 100 kHz
- 2 independent video sync sensing channels
- 2 RCA jacks for each channel to allow loop-through operation
- 2 solid-state outputs that send a logic low signal when sync is present
- Front-panel LEDs that display on/off status for each channel
- Compatible with all AMX solid-state and closure input ports
- Detection of audio, video, and high-resolution RGB signals
