CONNECTING DEVICES
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 Sound
Out to External Speaker (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
Also, 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.)
