AUDIO SYSTEM
The Audio Outputs always feed a low-level audio signal from the selected input.
The Audio Outputs feed a Monophonic signal whenever the selected input source has a Monophonic
audio signal (e.g. a monophonic broadcast from the built-in TV Tuner, or the signal from a Monophonic
VCP connected to the VIDEO 1, 2 input terminals).
The Audio Outputs feed a Stereo signal whenever the selected input source has a Stereo audio signal
(e.g. a stereo broadcast received by the built-in TV Tuner, or the signal from the built-in DVD player).
The EXTERNAL SPEAKERS OUTPUT CONECTOR feeds a high level mono or stereo signal whose
level is Variable up to 2.0W maximum when connected to 4-ohm speakers.
IR (Infrare Rays) Transmitter
The built-in IR Transmitter allows you to listen to the Stereo or Monophonic audio signal from the select-
ed program source (TV, DVD, VIDEO1, VIDEO2) on IR Wireless Headphones compatible with those

1. LSMD-121 INSTALLATION
EXAMPLE
Install the unit to metal pillars in the vehicle's roof with 4
screws. If the pillars are not conveniently located, secure a
3/8" plywood board to the pillars and mount the LSMD-121
to the plywood board.
Use extreme care to insure that tools do not
damage the unit.
Use extreme care to insure that cutting tools
and/or mounting screws do not contact, cut or drill
through exterior body panels.
