Connecting a Digital
Amp
Using an optical cable, connect the
digital audio input port of a digital amp
to the OPTICAL DIGITAL AUDIO
OUT 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
to Audio Out (Optical/HDMI ARC)
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.

NOTE
•
Refer to the user manual of the
audio device to connect.
• When connecting this product
to other devices, make sure
to turn off and unplug all the
devices.
• The audio output of this
product has wide-ranging audio
bandwidth, so the receiver
volume must be adjusted
properly. Speakers can be
damaged by unexpected high
frequencies.
• Connecting the OPTICAL
DIGITAL AUDIO OUT port
of the projector to the digital
audio input port of a digital
amp and the audio input port
of the projector to the analog
audio output port of the digital
amp can cause sound oscillation
due to the closed loop. Remove
one of the two connections to
prevent this. (This also applies
to home theater devices.)
