can't separate mono from stereo

[datrickstar]

Hi, I've got a Hi-fi that has 2 stereo aux inputs, and 2 stereo outputs. I am trying to get the speakers to become mono so i can use them for surround.
I have got 2 RCA/2 to 3.5 Stereo adapters and some 3.5 Stereo to RCA/2 cables, 3.5 stereo splitter + extender + M-M
I have tried putting the 2 adapters on both inputs, then using a 3.5 stereo to RCA/2 and connecting the red to one adapter, then the white to the other. I don't get any panning at all, anyone got any ideas?

Welcome to the forum!

Do you want to have a set of rear speakers that play the same audio as the front (i.e. the rear right is the same as the front right, and the rear left is the same as the front left)? If so, does your receiver have two sets of speaker outputs (A and B)? I imagine that is the case based upon your description. If that's the case, the you don't have to worry about modifying the inputs to the receiver. You would just hook up the second set of speakers to the B outputs, put them in the rear, and turn both sets of speakers on. You just want to make sure that your receiver can handle both sets of speakers (check the impedance of the speakers versus what the receiver is designed to handle).

Basically yeah. my reciever has 2 stereo inputs for aux and 2 stereo speaker outputs. both speakers are stereo and i only want left on one stereo speaker and right on the other. The speakers are supported cos they came with hi-fi control unit

thanks

Has anyone got any ideas on how i can do this? If i have 1 stereo input, a hi-fi with 2 stereo aux inputs and 2 stereo outputs, how can i make the hi-fi give me left and right panning?

I suggested a way to do it, but I might be misunderstanding. You say that you have two stereo speaker outputs. Does that mean that you can connect two pairs of speakers? If so, try the way that I suggested.

BTW, what is the make and model number of your hi-fi?

The hi-fi i'm usin is Pacific MP 143

Is the receiver stereo, not a 5.1 or other kind of surround? If it's stereo only, the old way to get ambient sound was to connect the positive terminal of a speaker to the Right + speaker terminal and the speaker - to the Left speaker terminal. If you want to adjust the level, you would need a volume control. You don't want to do this if the speakers are 4 Ohm, unless you use a volume control. You also can't do this if the amp is dual-mono with separate speaker negatives, two mono amps or a tube amp with separate channels/output transformers, because it needs a common ground in order to work.

Close, so very close.

I think you're trying to describe how to get the "difference signal" between two channels.

In such case, you would connect one side the speaker to the "+" side of the right channel and the other side of the speaker to the "+" side of the left channel.

This will produce "something" given a stereo signal (nothing with a mono signal), but it's not mono and it will need to be padded down to not overpower the other signals. I used this in my '70 Duster when my hair was dark and plentiful (and grew on my head, not out of my nose and ears) to feed the front center speaker while the two 6x9's in the rear deck provided the stereo, and the bass. It was a mediocere way of using that 4x10 up front.

As for the OP, you're playing with fire, possibly literally. You just can'y wily-nilly combine the outputs of two different channels. At best, nothing happens when you try it and the unit still works when you remove the wiring. At worst, the unit doesn't work again ...ever.

The reciever is stereo, i just wanted to use the speakers as part of surround sound like left/right rear. Both speakers are 4 Ohms aswell.
