Connecting video source devices
You need only connect the projector to a video source device using just one of the connecting
methods, however each provides a different level of video quality. The method you choose will
most likely depend upon the availability of matching terminals on both the projector and the video
source device as described below:

Connecting audio
The projector has one built-in mono speaker which are designed to provide basic audio
functionality accompanying data presentations for business purposes only. They are not designed
for, nor intended for stereo audio reproduction use as might be expected in home theater or
home cinema applications. Any stereo audio input (if provided), is mixed into a common mono
audio output through the projector speaker.
The built-in speaker will be muted when the AUDIO OUT jack is connected.
Note:
•
The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See
"Connecting audio" on page 27
•
If the selected video image is not displayed after the projector is turned on and the correct video source has been
selected, check that the video source device is turned on and operating correctly. Also check that the signal cables
have been connected correctly.
Playing sound through the projector
You can make use of the projector (mixed mono) speaker in your presentations, and also connect
separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output of your
Video source device to that sound system, instead of to the mono audio projector.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus.
The table below describes the connection methods for different devices, and where the sound is
from.

Audio output port
The selected input signal determines which sound will be played by the projector speaker, and which
sound will be output from the projector when AUDIO OUT is connected. If you select the PC signal,
the projector can play the sound received from AUDIO IN mini jack. If you select the VIDEO signal, the
projector can play the sound received from AUDIO (L/R).
Connecting smart devices
The projector can also project the content directly from your personal device(phone, tablet, NB)
through optional BenQ wireless solution such as Qcast dongle or InstaShow™.
Please consult to your local agent if you're interested in it.
