 Digital TV - Set-Top Box (DTV-STB) or DVD Connection
This television is capable of displaying 1080i and 480p DTV signals when connected to a DTV Tuner set-top-box (STB). In
order to view DTV programming, the STB must be connected to the component video inputs (Y, P
B , PR ) of the television.
A DTV signal must be available in your area. Select the output of the STB to either 1080i or 480p.
This television also utilizes a progressive scan doubler, which de-interlaces the NTSC signal and progressively scans the
image. This allows you to sit close to the TV and not see the thin black horizontal lines (venetian blind effect) associated
with interlaced TV pictures.
Use this diagram to connect the Panasonic DTV-STB (Digital TV-Set-Top Box) or DVD Player to the back of your TV.
Note:
There are 2 sets of three video inputs, Y, P
B , and PR . Separated component color inputs provide luminance and color
separation. Furthermore, the L (left) and R (right) audio inputs must be used.
 Amplifier Connection (TO AUDIO AMP)
To listen through a separate stereo system, connect an
external audio amplifier TO AUDIO AMP outputs on back
of television.
Note: TO AUDIO AMP terminals cannot be connected
directly to external speakers.
Select SPEAKERS OFF & FIXED AUDIO OUT to control
audio functions through the external amplifier.
