SansSuit 1 #1 August 19, 2012 I live in my den. Whenever I'm not jumping or working I'm here at my desk. In this den I have 3 audio devices. I am looking to merge all 3 outputs into a single, controlable, output running to a good set of powered speakers. (mixer board?) I need to do this on the cheap. I have: An iPad A computer A Television All 3 have 3.5 mm stereo jacks for outputs. The powered speakers have a 3.5 mm plug. I looked on line but I must not be asking the right questions because I'm not finding what I want. Most are set up for 1/4" jacks. I find it difficult to believe that this thingy doesn't exist. I do have modest soldering ability. If this thing could be made simply enough, I would be interested. Thanks for any help.Peace, -Dawson. http://www.SansSuit.com The Society for the Advancement of Naked Skydiving Quote Share this post Link to post Share on other sites

Fast 0 #3 August 20, 2012 Do you want them all on at the same time? Otherwise radio shack - selector switch - and some basic wiring will solve the problem. If you want a mixer that lets you hear them all at once, then your options are the ones that you have found with a 1/4 converter.~D Where troubles melt like lemon drops Away above the chimney tops That's where you'll find me.

billvon 2,467 #4 August 20, 2012 Mix all the inputs with a 1K resistor to ground plus a 1K resistor to a common output. Connect the common output to the input of your speakers. Your volume will have to be about 3x what it normally is to get the same output. Alternatively use an op amp (TL082 should work) at the common node to give you a 3x amplification (or any amplification you like.) For this you'll need a power supply of course. Parts should cost around $10 at Radio Shack. Quote Share this post Link to post Share on other sites

SansSuit 1 #7 August 22, 2012 This is what I'm looking at. http://www.sweetwater.com/store/detail/SplitMix4/ However it states, "Designed primarily as a line-level mixer for medium input/output impedances..." I don't know impedance from impotence. Would this, in conjunction with the aforementioned adapters work for my set up?Peace, -Dawson. http://www.SansSuit.com The Society for the Advancement of Naked Skydiving Quote Share this post Link to post Share on other sites

A pre-amp of some sort would be ideal, but that mixer should work, in conjunction with the 1/4 inch headphone adapters. All you need is something that can accept at least three inputs and send the signal out through a single channel.Math tutoring available. Only $6! per hour! First lesson: Factorials!

SansSuit 1 #11 September 25, 2012 And in the end, this set-up does exactly what I wanted it to do. Cables and adapters cost a little more than what I had in mind but all is good.
