So, I apologize if you think this is a duplicate, I couldn't move the other post here, else I would have. This is my situation.
I bought my MLT 2 home theater from Newegg and have plugged it in with a Yamaha RX-373. The sub had a small crack near the leg which is cosmetic. I have plugged everything in and want to test if it is working correctly. Initially I smelt a little bit of electrical burning near the fins. I have plugged in the RCA cable to the LFE Right input in the sub.These are my settingsSub-woofer settings
1. Turned the Control dial to the maximum
2. Turned the Low pass filter control to the maximum
3. Set the phase at 0 (not 180)Receiver settings
1. Turned all speakers to small
2. Set Cross over at 100 Hz
3. Set the following levels - Front L, Front R, Center, Surround L, Surround R at 0.0 dB and Sub-woofer at -6.0dB. I did this to isolate the sub
4. Set the equalizer to the lowest level for all the 5 channel.Issues faced
1. To test the sub, I ran a few sub-test songs on YouTube and found that the sub did make some thumps but I am also hearing music from the other speakers despite the above settings. My assumption was that if I made everything else minimal, all sound would be redirected to the sub. How do I isolate the sub?
2. I am still not sure if my sub works as expected. How do I really do a fool proof test to ensure it works? I don't want to return if its a good product but I am running out of options
3. Is the slight electrical smell a big issue? I had rather not return the whole set because I do think the other speakers are working well and there is no guarantee that the next package that comes in as a replacement will not have damage.
4. While on the topic, can someone also advise how to configure the system so that the voice is not drowned out by music while watching movies?
I would really appreciate if someone can guide me on this. I am very new to the Home theater situation and want to ensure I got a good working product
