Using the TV’s Menu System
Fixed/Variable Out
The Fixed/Variable Out menu displays a choice list that lets you turn the TV’s
front internal and external speakers on or off and set the Fixed/Variable audio
output to a fixed- or variable-control level. The choices are:
• Variable Output, Speakers On This setting 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
amplifier and the volume is controlled by the TV.
• Variable Output, Speakers Off This setting 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 amplifier
and the volume is controlled by the TV.
• Fixed Output, Speakers Off This setting turns the TV’s front speakers Off
and provides fixed output from the TV’s Fixed/Variable Audio Output jack to
a receiver or amplifier. 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 amplifier that has its own remote control
for controlling the volume.
Note: If the Internal Speaker source switch on the back of the TV is set to
EXT AMP, it overrides any above setting of Speakers Off and allows the
internal speakers to be used as a center speaker input.
Digital Audio Out
If you’ve connected a six-channel receiver to the TV’s DIGITAL AUDIO OUTPUT
jack with a digital optical cable, you can receive Dolby Digital* surround sound
if transmitted. Choose the correct setting in the Digital Audio Out menu:
• Auto Select If selected, 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) If selected, the TV sends all signals through
the Digital Audio Output in PCM.
Subwoofer
The built-in Subwoofer enhances low-frequency audio. The Subwoofer setting
can only be changed if the Fixed/Variable audio output is set to the Variable
Output. The choices are: Subwoofer On or Subwoofer Off.
Note: The Subwoofer setting turns Off when Variable Out, Speakers Off is
selected in the Fixed/Variable Out menu.
