CONNECTING DEVICES
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
theatre devices.)
