I realize I can't just wire two audio sources in parallel since they'll then be driving each other.Commercial solutions appear to all involve amplification and volume control, which my two sources already have.How can I combine audio signals from the headphone outputs of two different devices while still presenting just the impedance of the headphones to each device?

One is that in order to keep a low devices 1 headphone 2 output you need to use low value resistors and this loads each output excessively, plus creates a voltage divider between the outputs.Each output in the above example would see a ohm load e.

This solves the loading issue now each output sees 3.

Say we have 3 inputs of 1V pk-pk.With all three plugged in, the contribution of each output will be a maximum of mV.This is okay as we can add a gain of 3 to the opamp to compensateas long as we don't unplug one of the signals.

If we unplug one of the signals, we change the loading on the other two and the voltage divider changes.The signal voltage from each will now be mV.If we unplug another then the full 1V pk-pk will be output.So the output level of each channel is greatly affected by change of the devices 1 headphone 2 inputs - not just unplugging, imagine using volume controls.

This is a current amplifierand uses a virtual ground at the summing point devices 1 headphone 2 prevent any interaction between the channels.If we remove an input, the voltage contribution from the other inputs stays the same.So this is the best simple mixing circuit out of the three shown.

The ESP pages linked to by Shimofuri are an excellent source of such information.A non-inverting summing opamp circuit is the simplest mixer you can construct.

The value of the input resistors is the impedance presented to the devices.Please check out this link from one of the best audio resource in the Web sound.You're looking for what is commonly known as a " combiner " the opposite of a splitter or in the audio world it is referred to as a "mixer".

ArgentoSapiens ArgentoSapiens 1 3.A simple passive resistive mixer is basic, but a bad solution for a couple of reasons: A solution to this problem is the active inverting opamp mixer: Oli Glaser Oli Glaser Why all the effort to increase the impedance seen by the headphone outputs?

There is no point wasting power devices 1 headphone 2 doing otherwise.Then the opamp maybe attached to an output amp like the LM can drive the headphones.The passive mixer may suit your requirements if you want to keep it simple, but you can't avoid the devices loading each other.
