Every night I listen to radio in bed, sometimes for a few hours if I can't sleep. I use earbuds which are fairly small, but lying on one side for a while means the laid-upon ear gets a bit painful. If I'm listening to a mono radio station then no problem, I can pull out an earphone. But that doen't work with stereo.
Is there a simple way of combining the two stereo channels to mono without stressing the output stage of my radio, headphone amp or whatever?
I'm guessing there'd be a loss of gain but that's no issue. It's a kind of total crossfeed I suppose.
Hi Derek: Sorry I took so long giving a reply. I would recommend getting 2ea. 22 ohm 1 watt resistors. Connect the leads at one end of the resistors together; this connects to the output of the mono sound source. The leads at the other end are connected to the left & right hot side of the phones. You could put them in a small plastic case with the output from the radio going in one end mounting and an appropriate phone jack at the other end of the case with the resistors connected inside the box as described above. Make sure the common or ground lead at the output of the radio is connected to the barrel of the phone jack as you will have the end of each resistor connected to the tip & ring of the phone jack. Hope I made the description clear enough.
