descrIPTIon
The Extron FBI 100 Feedback Loop Isolator is designed to prevent potential feedback loops
when a VCR is used for both recording and playback in an A/V system. As the VCR records
signals through its A/V input, such as from a video camera and microphone, it outputs the same
signals back into the system. The FBI 100 prevents the audio feedback loop, represented as a
progressively loud tone that can occur if the VCR output signal is routed back into its A/V input
via a switching system.
For example, feedback is likely to occur in a videoconference environment when mixed audio
from the videoconference session is simultaneously recorded and introduced back into the
system as an active source.
In record mode, the FBI 100 prevents feedback loops by directing the information to be recorded
specifically to the VCR's A/V input while isolating the VCR output from the rest of the system. For
other VCR modes, such as playback and stop, the VCR outputs to the A/V system as normal.
Contact closure control provides a simple means of selecting the record or playback/stop mode
of the FBI 100. Part of the VersaTools
®
line of small, economical, integrator friendly products,
the FBI 100 is housed in a 1U, quarter rack width metal enclosure.
