I represent ASA Electronics, the producer of the JENSEN brand of televisions, stereos, and speakers, Voyager brand of observation monitors and cameras and the Advent brand of appliances. At ASA, we strive to provide excellent customer service and product satisfaction and would like to offer some assistance in this matter.
It sounds like you are connecting the TVís Audio Out direct to non-powered speakers, bypassing the stereo. This will not work, as the TVís Audio Out signal is a line-level signal designed to connect to an amplifier, which in-turn powers the speakers. Please connect the TVís Audio Out to the stereoís AUX IN and place the stereo into the AUX IN mode. Then the audio out from the stereo must also be connected to the desired speakers (the JENSEN wallmount stereos have speaker "zones", selectable by a switch on the stereo). Also, you will need to set the TVís internal speakers to OFF in the Audio set-up menu, as this will enable the Audio Out jacks.
If you still need further assistance with this, I think it would be best to call us or visit your dealer. You can reach us on our toll free technical support line at (877) 845-8750. We are available M-F 8:00 AM until 6:00 PM EDT.
We look forward to hearing from you.
JENSEN, Voyager & Advent Tech Support Team
