Inserting things into my nads...
 
Not sure what to call this, but it's something that I need just for my desk/computer audio setup. I want to be able to send signal from both the headphones out of my computer, and my CD player to one 'channel' of a NAD 7120 Receiver. I want to be able to have level controll on both, so in reality 4 channels of audio. What I see me needing to do is put diodes on all four signal lines and then pots on them. Is this the right way to go about doing this? I basically want to make a mini-mixer type idea, but don't need all the features such as eq . I'm not sure what this is called or I would have searched. If anyone has done this or knows how to, or knows what I am looking for, I would appreciate it. If you have a schematic or pcb layout, even better.

Thank You,
Cam

why not just buy a 1/8th jack to rca adapter ?

PLug one end into your line out / speaker out on your commputer and then the other into cd on your nad..

Because that's what i'm doing with the computer, and I want to be able to listen to a cd and my computer at the same time.

You can't run 2 amps into 1 pair of speakers keeping it so that both are mixed in stereo

CD drive is usually being used.

And you can't run 2 sources on a amp.. well you can with a pair of y adapters but this all sounds so retarted and waste of time.. why are you doing this again.. who on earth listens to 2 audio sources at the same time ?

I would like to.

Ever been to a concert?

It's not that stupid listening to two audio sources, I sometimes used to play games with all sound effects, whilst listening to some appropriate CD music instead of the poor MIDI In-Game music...

You could try it a with two simple stereo potentiometers, and then mix both channels into one... No diodes required. From there on, you can make it as complicated as you want :)

The easy-to-buy solution: A small (studio/DJ) mix panel?

Cheers!
