(3) MTS / STEREO
The LSMD-121 incorporates a MTS/STEREO (Multichannel Television Sound) decoder to receive:
MONOPHONIC broadcasts
STEREO broadcasts (if the station is broadcasting in Stereo)
SAP (Secondary Audio Program) broadcasts. SAP material might be an audio track in an additional
language, or it might be DVS information (Descriptive Video Service ) for the visually impaired.
To select the MTS mode:
Press the TV/Video button as necessary to switch to TV Mode.
Press the MENU Button until "MTS" is selected.
A sub-menu will be displayed as shown below:
Each time you press the VOLUME button, the selection will change in the order MONO - STEREO
- SAP. The chosen mode will change from WHITE to MAGENTA.
Press the MENU button repeatedly until the menu disappears from the screen.
Whenever you change channels or switch the LSMD-
121 to TV mode, the MTS mode will be displayed on
screen after a brief delay as shown below.
In this example, the station is broadcasting both STEREO and SAP signals. You may also call up this
display at any time by pressing the DISPLAY button on the remote control.
If MONO mode has been selected, the on-screen display will not indicate a STEREO broadcast even if
it is available.
NOTES:
Reception of Stereo or SAP broadcast information is of course dependent on a television station actually
broadcasting such material. Not all stations do, and some stations only broadcast Stereo/SAP material
during part of the day.
If the LSMD-121 is set to STEREO and no stereo signal is being broadcast, a MONO signal will automati-
cally be received.
A stronger signal is required to receive Stereo or SAP broadcasts. If noise is heard, you can improve the
clarity of the audio signal by switching to MONO reception.
If a received SAP signal is weak, SAP will not be heard.
Some stations broadcast the same audio signal on the SAP band to insure that the viewer will still hear
audio if the television is accidentally set to SAP reception.
Even if both STEREO and SAP are broadcast, only one can be heard at a time.
Transmission of CABLE TV signals differ from off-air TV broadcasts. It is possible that MTS sound may not
be received satisfactorily.
