DP-4X CHASSIS PICTURES

PAGE 07-05

This picture shows a close up view of the DP-43 Rear Panel.
(1)   ANTENNA INPUTS: Antenna A: feeds the Main Tuner and Sub (PinP) Tuner.
   When switched to Antenna B, the RF from Antenna A is output "Out To Converter"
   The Main Tuner now receives it's RF input from Antenna B.
   The Sub PinP Tuner does not receive RF inputs from Antenna B.
(2)   AUDIO INPUTS: For inputs 1, 2, 3 and 4.
(3) MONITOR OUT: What ever has been selected for the Main Picture will be available on the
   Monitor Out.
   S-Out is only available when S-In is used.
   Audio to Hi-Fi can be set by the customer's Menu to be either;
         Fixed: Use this for feeding Audio Out to an external Audio Decoder.
         Variable: Do not use for external Audio Decoder. This output is volume controlled.
(4)   COMPOSITE or S-IN INPUTS THREE and FOUR.
(5)   COMPONENT INPUTS ONE and TWO.
(6)   HDMI INPUT. See page 07-04 for an example of the comparison between HDMI and DVI from the
   previous models.. HDMI is the next generation from DVI.(7) RS232C.
   For use with third party home Audio/Video control systems which are commercially available
