Using the TV’s Menu System
SAP (Second Audio Program)
When turned on, Second Audio Program plays the program’s audio in a second
language, if one is available. SAP is also used to broadcast a program’s audio
with descriptions of the video for the visually impaired. Or, SAP might contain
audio which is totally unrelated to the video.
Note: SAP is broadcast in mono and is only available for analog programs,
not digital programs.
Balance
The Balance setting applies to the internal speakers, rear external speakers and
the headphone output. Balance does not affect the internal subwoofer nor any
other audio output. Balance is how much audio (loudness) gets sent to the left
and right speakers.
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 amplifier/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 Dolby Digital* and PCM decoder 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.
