OPERATING GUIDELINES
This manual covers installation and operation the PFD-4X4 and PFD-4X2 family of matrix
audio video switchers. Most of the operating principals are identical on all models. The unique
characteristics such as connectors and pinouts are detailed on the application drawings.
PFD FRONT PANEL OPERATION
LED INDICATOR LAMP BEHAVIOR
The color and state of the indicator LED's provide the following status information.
RED LED: indicates Video route or selection z
GREEN LED: indicates Audio route or selection z
GREEN LED FLASHES after an input push button is held z
down enabling audio input level adjustment
NOTE: Input and output status LED's will turn off after 30 seconds of front panel inactivity.
VIDEO / AUDIO SOURCE SELECTION AND OUTPUT ROUTING
Video and audio can be routed in either follow or breakaway mode. This will depend on the status
of the VIDEO and AUDIO select pushbuttons. If both AUDIO and VIDEO select pushbuttons are
selected, the audio source will follow the video source. The video or audio select pushbuttons, when
selcted independently, allow for breakaway routing.
The video and audio sources are selected and stored by pressing one of the four INPUT SELECT
buttons located on the left side of the front panel, selecting the desired OUTPUT SELECT button
and pushing the SELECT button. The input and output LED's will turn off after the SELECT button
is pressed.
The output pushbuttons can toggle the output selections on and off by repeated pushes. The video
and/or audio LED's will be illuminated to indicate the current I/O selection when input or output
buttons are pushed. The escape button, when pressed, will clear the current selection and revert to
the previous route status. The last I/O route selected will always overwrite the previous I/O route.
Note that the audio or video sources on a particular input may be separately routed to different
outputs. This is referred to as audio breakaway.
