Video Monitors and Televisions
sound or low volume on some channels or programs
Your television may
be set to receive SAP audio instead of normal audio. Most newer
sets have a feature that allows you to select three different
types of audio signals, Mono, Stereo or SAP. To confuse the issue
even more, Mono is sometimes referred to as Normal, but on other
models Stereo is referred to as Normal. Stereo may also be referred
to as MTS. SAP stands for Separate Audio Program, and is the one
selection you don't want selected if you are having problems.
For more details about SAP, read on. Otherwise, consult the manual
on your television to determine how to change the audio selection
on your set from SAP back to one of the normal settings.
Since the introduction of stereo audio in broadcast television
a few irritating problems have cropped up. An additional "little
known" feature was added at that time called Separate Audio
Program, or SAP. SAP gives broadcasters the ability to send out
the audio signal in more than one language which can then be selected
on the viewers television. Unfortunately, since the use of this
feature isn't wide-spread, most viewers don't know how to use
it or even know their T.V. is capable of doing this.
To make matters worse,
there is really no standard on what is done with the SAP channel
if it isn't needed for another language. Sometimes it's left empty,
other times it has the same audio track as the normal channel,
but in the worst cases their is a very low volume recording of
the normal channel on it. This becomes a real problem when someone
accidentally switches their T.V. sound to SAP, instead of the
normal mode which is very easy to do on some models. Now, if you
did this by accident and suddenly everything you watched was in
Spanish, you would realize what had happened immediately. But
since the channel is only rarely used for another language, it
is more likely that one of the other things mentioned will occur.
Most frequently you won't notice a thing because the most common
practice is to duplicate the normal audio track on the SAP track.
So, it is very likely that the viewer may not have a sound problem
until days later when they happen to hit a program that has left
the SAP channel blank, or at low volume.
How do you solve the
problem? Switch the audio back to the normal stereo, or mono channel
on your television. We can't tell you how to do this since every
make and model uses a different method. In general, look for a
button marked SAP or audio on your remote control. If it's not
there, you will probably have to find it in the on-screen menus
of your set. Of course the best way is to find your owners manual
and follow the directions there.
