The Audio Connections menu has screens for setting up
inputs or outputs that are associated with audio:
•Fixed/Variable Out: Choose output type; set up subwoofer.
•Digital Audio Out: Choose either Auto Select or PCM output.
•DVI Audio Input: Choose a TV audio input for a DVI device.
Fixed/Variable Out Displays a choice list that lets you turn the TV’s front
internal speakers on or off and set the Fixed/Variable audio output to a
fi xed or variable volume output level. The choices are:
• Variable Output, Speakers On Turns the TV’s front speakers On
and allows variable output from the TV’s FIXED/VARIABLE AUDIO
OUTPUT jacks. Use this setting if the TV is not connected to an audio
receiver or amplifi er and the volume is controlled by the TV.
• Variable Output, Speakers Off Turns the TV’s front speakers Off
and allows variable output from the TV’s FIXED/VARIABLE AUDIO
OUTPUT jacks. Use this setting if the TV is connected to an audio
receiver or amplifi er and the volume is controlled by the TV.
• Fixed Output, Speakers Off Turns the TV’s front speakers Off
and provides fi xed output from the TV’s FIXED/VARIABLE AUDIO
OUTPUT jack to a receiver or amplifi er. With the Fixed Output, the
TV’s volume control, graphic equalizer, and mute are disabled. This
output is ideal when connecting to an audio receiver or amplifi er that
has its own remote control for controlling the volume.
• Is an external subwoofer connected to the Subwoofer Output?
This option only appears when Variable Output, Speakers On is
selected. Select Yes if you want the low frequency audio sent from
the SUBWOOFER Out jack to the connected external subwoofer and
high frequency audio sent to the TV’s speakers; select No to send
full-range audio to the TV’s speakers. For the Speakers Off option, the
SUBWOOFER Out jack is always enabled.
Digital Audio Out Allows you to receive Dolby Digital surround sound
if transmitted and you’ve connected a six-channel receiver to the TV’s
DIGITAL AUDIO OUTPUT jack with a digital optical cable. Choose the
correct setting in the Digital Audio Out menu:
• Auto Select Your TV automatically chooses between Dolby Digital
and PCM based on the audio signal it is receiving. This is the best
selection if you have a decoder with Dolby Digital and PCM that was
manufactured in the last several years.
• PCM (Pulse Code Modulation) The TV sends all signals through the
Digital Audio Output in PCM.
DVI Audio Input Allows you to select the audio input you’re using if
you’ve connected an HDMI/DVI cable adapter to the DVI input. Select from
the inputs listed. Go to page 16 for more information.

Because an HDMI output carries the audio signal on the same
cable as the video, no setup is needed. However, if you
connect a DVI output to the TV's HDMI input, you need to
connect the separate DVI audio to one of the TV's audio
inputs and select that input in this screen. The TV will use
that audio input for sound when it displays a DVI signal.
Select the TV audio input where the DVI audio is connected.
