A:Answer Yes it does - standard 3.5mm(1/8") stereo (min-pin) jack.
From the manual:
Connecting to External Speakers
To enhance the sound from your presentation, you can connect the projector to external self-powered speakers. You can control the volume using the projector's remote control.
You can also connect the projector to an amplifier with speakers.
If you want to output audio from the external speakers when the projector is turned off, you need to select Always On as the A/V Output setting in the projector's Extended menu.
Note: The projector's built-in speaker system is disabled when you connect external speakers.
Make sure your computer or video source is connected to the projector with both audio and video cables as necessary.
Locate the appropriate cable to connect your external speakers, such as a stereo mini-jack-to-pin-jack cable, or another type of cable or adapter.
Connect one end of the cable to your external speakers as necessary.
Connect the stereo mini-jack end of the cable to your projector's Audio Out port.
