Connecting NESX Home Theater Solved

Question

Hello everyone,
I just bought a home theater system on sale (not too expensive). I've been trying to set it up for an hour with no luck. The equipment is a NESX 778i home theater:

First of all, regarding the connections, I don't understand. The back of my cabinet looks like this:

Then on the upper part, I have:

And on the sides:

With this package, I have an RCA cable and 2 large cables for the red and black speaker outputs.
How does the connection work?

Thank you for your help.
Best regards.

Configuration: Mac OS X / Safari 535.1

For everyone who has the piece of furniture NSEX - NE-778 - :

It is normal not to have the sound from your TV coming through the amplifier of the furniture = because the RCA terminals on your TV are "IN" (input) terminals

For 10 euros = buy a SCART cable with 3 RCA outputs at the end (red and white for sound and yellow for video) plus the "IN or OUT" switch on the SCART.

Once the cable is connected to both devices, set the switch to "OUT"...

And if the sound still doesn't come out, connect the 3 RCA to your internet service provider's TV decoder = and there the sound is like at the movies......

Enjoy the movie.... (I don't regret having even taken the display model at -50%)

Hard to find the manual, but given the announced power, the contradiction between Blu-Ray use and its connectivity, the simplest thing would be to return it; it resembles a "Rube Goldberg machine."
For the same price, fully equipped, you can get this kind of equipment: https://www.homecine-compare.com/ensemble-home-cinema-LGHX906SB-LG-HX906SB.htm
Otherwise, if you had the assembly diagram, your photos are blurry.

That's incredible, I ask for help and I'm responded to with a suggestion to buy another product.
I bought it as a display model, which is why I didn't pay much for it and there are no manuals.

Regarding the photos, the most important ones are not blurry. The photo at the back of the device with all the connections is:

And I think that from there, I should be able to connect my speakers, which are of the type:

(There is a red wire and a black wire)

Thank you for your help.

Since you have a stereo RCA input, connect the device, TV, or DVD/Blu-Ray player to this "Audio IN" input. As for the speaker wiring, you need to determine the stereo output, connect the two provided cables (+2 and -2) to the upper part, and to the column.
Finally, the announced maximum power consumption is 60W, which means that not much acoustic power will come out of it.
If you're connecting a TV, turn off its speakers and switch to "audio system" if available. With a DVD/Blu-Ray player, switch to PCM and not bitstream.

Thank you, but the problem is that I can't see where to connect the + and - terminals of the speakers, since the rest of the connections are here:

Where do my + and - cables connect? Because there are only RCA outputs there.

I'm going to snoop around a bit because that's the question I'm asking myself too; there should be two speaker outputs.
Could you do a close-up of the labels on the back and the speaker connections present?
I have another idea: what is the length of the speaker cables? Is this piece of furniture designed to be assembled only as shown, or can we "explode" it and install the modules in different ways?

Thank you for your help.
So behind the top part, in the middle I have: http://img11.hostingpics.net/pics/676936photo1.jpg

On the sides I have:
(At the top) http://img11.hostingpics.net/pics/464482photo1.jpg
(At the bottom) http://img11.hostingpics.net/pics/681150photo3.jpg

With this furniture, we can create a separation (there are no connections at the bottom parts).

When we look, the connectors for the speakers are inputs, so we need to send an audio signal into them. But the problem is that I don't know where to retrieve this audio signal.
At the output we only have RCA connectors, could we send from an RCA back to the two + and - connectors for the speakers?

stewartia · Answer

I don't think so, the sound must be amplified to go to the speakers, and the audio outputs shouldn't be amplified; it's just a signal relay to be amplified as well.

So what should I do? Am I missing some equipment? Or do I need to make a specific connection?

stewartia · Answer

Have you tried connecting only the RCA cable from the TV output to the input of the upper part of the furniture?  Remember to turn off the TV speakers.

stewartia · Answer

If you bought it near you, ask the store for the manual, and also check if anything is missing.

stewartia · Answer

You could contact the seller here: http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&clk_rvr_id=253564691071&item=330596521015, pretend that you want to buy it, and ask for the supplied materials and how to install it exactly.

Thank you for this help.
I think there is simply a problem.
I tried connecting an amp (an old one I had at home) to the upper parts, it doesn't work.
In the lower parts, it works.

Conclusion, there is a problem with the upper block, and the speaker outputs should be connected to those of the lower part. And the sound is sent directly from the source to the upper speakers (not visible to the user).

Afterward, I wonder what it could be...

stewartia · Answer

And by connecting the upper part to the lower part? Indeed, that's where the amplifier should be located; the front speakers of the upper part should logically have an internal connection, rather than an external one. You could give it a try.

Wfree · Answer

Thank you for your help. I took it back to the store; it had a design flaw...

Come back if you have another purchase idea, in order to weigh the pros and cons.
