Any1 no a cct for converting mic to Line level (RCA's)

[scottb721]

I'm hoping to build a "box" that I can plug a mic or two into and have that then connect inline on the Audio Line Out going from the DVD player to the TV. The DVD audio and mic(s) would then be mixed.
A mic volume control would be nice too.

Anyone able to provide cct info ?
or direct me to a more relevant forum.

Thanks

Regards
Scott

So you need to have a box with 3 inputs. 2 mikes and 1 from the DVD and then have 1 output to the TV? If so, we should be able to just buy 2 RCA Plugs, Whatever kind of mike inputs you want run each line to its own variable resistor (Pot) then from the tap line on the "Pot" to the output jack. Let me know and I'll sen you something.

That will not work.

You will need to mix the two mic inputs and then have a gain stage to get the signal level of the mic input to the same level or higher than the DVD output. Then I would buffer the DVD and mic preamp output before the level adjustments and mixing. The final step would be to buffer the output of the mixed signals to drive the TV input.

ESP and others have mixer circuits that would work for you. Just do a search for mic mixer circuits.

What you need is better to buy ready made as it is easier to get right and cheaper as well:

Any small mixer like a Spirit Folio Notepad should be Ok for this. Would cost about the same as the components and box.
