Reference: External Mono Speaker Setup
The three-contact SPEAKER OUT 3.5 mm jack on the LQ630H and CQ610H rear panels provides mono speaker level signal outputs (audio -, audio +) for a single 8 ohm external speaker. Refer to the following diagram for pinout details.
On LQ630H or CQ610H TVs with software earlier than CPU v3.50.00 and PTC v1.00.029, this stereo jack provides a fixed-level 1 watt output. On LQ630H or CQ610H TVs with CPU v3.50.00 and PTC v1.00.029 or later, you can set Installer Menu item 097 AUDIO OUTPUT as the application requires for different fixed speaker levels or variable speaker output.
Caution: Do NOT plug in a mono connector, as this may damage the TV.SPEAKER
