I need the manual for the Durabrand HT-3915 home theater system

I recently received a Durabrand HT-3915 home theater system as a birthday gift. I set it up in the living room and tried connecting it to my old TV. The speakers connected, but the sound was strangely muffled and the bass was barely audible. I’d like to know if I’ve positioned the speakers correctly.

The manual only included wiring diagrams, but didn't go into detail about the amplifier's menu. I tried searching for a PDF manual online, but only found brief guides. Has anyone else set up the HT-3915 and can share their experience? Are there any specific considerations when connecting to an older TV model? Or where can I download a detailed manual for the Durabrand HT-3915?

Wow, there are so many different connectors—as far as I can remember. And there are different ways to connect them. Have you tried everything? Take a look at the user manual for Durabrand HT-3915 home theater system . That should have the exact wiring diagram for your model. I sometimes use this site when I can’t find the manual for various devices. If that doesn't work, try searching for similar models of this home theater system. I think they're all pretty similar in terms of diagrams and settings. Also, check to see if the amplifier is set to “Stereo” mode instead of ‘Surround’—on the HT-3915, you can switch this by holding down the “Mode” button on the remote.
