Connecting External Speakers
When you use EasyMP, you can output the sound to external speakers
with built-in amplifiers. First, you need to use the Settings menu to set
the
EasyMP Audio Out option to External . See page 121 for
instructions.
To connect speakers to the projector, follow these steps:
1. Locate the appropriate cable to connect your speakers.
Depending on your speakers you may be able to use a
commercially available audio cable with a stereo mini-jack
connector on one end and pin jacks on the other end. For some
speakers, you may have to purchase a special cable or use an
adapter.
2. Connect the stereo mini-jack end of the audio cable to the Audio
port on the projector.
3. Connect the other end(s) of the cable to your speakers.
The projector’s internal speaker system is disabled while sound is
output to external speakers, and you can’t use the projector or remote
control to control the volume.
