Connecting A Digital Amp - LG CineBeam Laser HF85LS Owner's Manual

Connecting a Digital
Amp
Using an optical cable, connect the
digital audio input port of a digital
amp to the
port of the projector. The output
of an amp with a digital converter
must be set to the desired audio
format. When using a HDMI cable
to connect a home theater or when
connecting an optical output to an
external audio device, set [Sound Out]
to [HDMI ARC] or [Optical] as shown
below. If a projector, home theater,
or the speaker of an external audio
device is operating at the same time,
there will be an echo.
