[sdiy] Stereo to mono summing..

[John L Marshall]

1. Use a dual voice coil headphone speaker if one exists.

2. Connect the left signal to one speaker connection and the right signal to
the other speaker connection. Do not use the ground wire. You will need to
invert the phase of the signal on one channel only. Be certain that each
channel of the headphone amplifier is capable of driving an eight ohm load.

Take care,
John

stereo headphone outputs and route the two signals (plus ground) to one
16ohm headphone speaker..  So we're wondering the simplest (cheapest,
smallest) way to get both signals at the one driver with no loss of volume
and with no distress to the amplifier.
