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]. If a 
projector, home theater, or the speaker 
of an external audio device is operating 
at the same time, there will be an echo.
Optional Extras
 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   
 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.)
