First of all I would like to thank you for taking the time to read my issue.

Ok so here is my dilemma.

I have a computer, an mp3 player, a mobile phone and a hi-fi.

I have a Sharp XL-30H hi-fi system with 2 standard speakers. Here are the specs, and I’m quoting from the manual here;
Type: Full range speaker system
Rated input power: 5 W
Maximum input power: 10 W
Impedance: 4 ohms
Amplifier output power: RMS; 10 W (5 W + 5 W) (10 % T.H.D.)

I have practically no idea what any of this means. I think watts is how loud they go, but I don’t know what impedance is, what RMS is etc… The way the speakers are connected to the hi-fi is through 4 wires. A left +, left -, right + and right -. The left + and – both go to the left speaker and the right + and – go to the right speaker. The following pictures illustrate this:

I think this is pretty standard for most home hi-fi systems.

My mp3 player and mobile phone both have a standard plug for headphones. It is a 3.5mm jack I think. The mp3 player and mobile phone have female connectors looking like the one below:

And this is the type of jack which fits into it:

My mp3 player is a Samsung YP-U2R and my mobile phone is a Sony Ericsson W810i. I do not know what power outputs either of these have when playing audio though their headphone sockets.

I also have a computer with standard female connection like my mp3 player and mobile phone. I have speakers for my computer (mains powered) which are Dell A215 with 1.5 W, RMS and volume control. They have a standard male connector (like for headphones) for the female connector on my PC. As I said above, I do not know what power output my phone and mp3 player have but I do know that when I connect my phone to my PC speakers, it takes the phone to be at full volume and the speakers to be at about 1/3 volume. When playing music from the computer, the speakers are usually at 1/4 volume.

So, you ask, why should I tell you all this? Well, you see I like playing music. And the music I like to play needs decent speakers to sound good. The built in speakers on my phone are very poor. The sound quality from my PC speakers and Hi-fi are good enough for my purposes. The only problem is, I like to play music in mp3 format and also listen to the radio. I have my mp3s on my phone, PC and mp3 player. The only thing is, when I want to listen to them (and have them played at a good quality) I have to turn on my PC.

Therefore, I was wondering if I could compile all my media sources (ie. My hi-fi, mp3 player, phone and PC) and play any of them at any time through my hi-fi and PC speakers. Obviously I would have to have my hi-fi and speakers turned on to do this, but it saves turning my PC on. Also, I could locate the hi-fi speakers at the back of my room and the PC speakers at the front of my room to get an even sound.

Maybe this diagram can demonstrate things better:

Some other things you should note. I am not willing to spend more than around £50 on this. I understand that I won’t get complete surround sound but so long as the left PC and Hi-fi speakers share the same left channel input and the same for the right speakers and channel, I will be happy. Also, please explain everything you say very clearly because I am new to this area.

If you have any questions at all, please do not hesitate to ask below.

PS. Sorry for the poor quality photos. I hope they demonstrate my question sufficiently.


Thank you in anticipation

Ok sit rep on my problem is as such.

I now know how to join the 3 3.5mm cables into 1 3.5mm cable. I know I need an amp.

The updated diagram is available here:
Updated diagram and information

All I need to know now is:

1. How can I join the speaker cables from the amplifier and Hi-Fi together? (W10)
2. How can I convert the RCA output from the amplifier into my type of speaker cable? (W9)
3. Is there an adapter which I has a 3.5mm male to 3.5mm male connector? (W1)
4. How can I make sure the amplifier is set up correctly so that I do not damage my speakers?

Can anyone help with any of these points?
