"Excellent! (my external audio only set-up - onboard speakers muted!)"4.5 starson by fredfass
Pros: Primo picture quality. Easy to transport.
Cons: Manual's pretty weak.
Summary: This is a great projector. The quality of the image is stellar. The onboard speakers are small but adequate for most people, but you're really missing out on the full movie-going experience without surround sound! Many people realize that you cannot mute the onboard speakers while external speakers are connected to the DV10. This CAN be achieved if you use the optical audio out. So, if want to mute the onboard speakers to get external audio (from surround speakers or headphones) while muting the onboard speakers here's the set up I'm using to achieve that:
-Bought an inexpensive Sony receiver (model STR-DG510)
-Bought an inexpensive 6' optical cable
-Bought JBL Surround Cinema Speakers (SCS200.5)
-Connected the optical cable to one of the optical inputs on the receiver.
-Connected my speakers to the receiver according to directions.
-Set my receiver's input setting to "Video 2" (this will vary depending on your connection and receiver).
-Using the DV10's remote, I pressed "Setup", navigated to "Audio Setup", selected "SPDIF OUT", and set that to "RAW".
My DV10's onboard speakers went silent but I was now getting fantastic 5.1 Dolby Digital sound through my external speakers! Connecting my headphones to the receiver means late night movies without waking the neighbors
