Ever wish you could split a headset in two so you can listen to two
different audio sources, such as your computer and a training
cassette?  Here's how.

   Split Headset Adapter (with optional amplification)

   A common need of computer users who are blind or visually
   impaired is to be able to listen through headphones to both
   their speech synthesizer and another audio source such as a
   transcribing machine.  For example, computer speech in the
   left ear and transcriber audio in the right ear.  To do
   this, use a stereo plug coupler (Radio Shack 274-1555) to
   connect your stereo headset to a Y-adapter (Radio Shack
   274-375) that splits the left and right channels.  Then,
   connect each of two mini phone plug cables (Radio Shack
   42-2420) to the Y-adapter.  Connect one cable to the
   earphone jack of your speech synthesizer.  Connect the other
   cable to your transcriber earphone jack.  If your equipment
   uses anything other than the usual 1/8" mini phone plugs you
   may need additional adapters.  Set the volume controls on
   each device to achieve the desired balance in each ear.

   For users who are also hearing impaired, the above
   arrangement may not supply sufficient amplification.  In
   this case, use a small stereo amplifier (such as the Radio
   Shack 31-1957 for about $60).  Use two cables (Radio Shack
   42-2444) to connect the speech synthesizer and transcriber
   earphone jacks to the amplifier left and right inputs.
   Connect your stereo headset to the built-in headphone jack
   on the front of the amplifier.  To maximize the
   signal-to-noise ratio, set the volume controls on the
   synthesizer and transcriber to near full volume.  Then
   adjust the amplifier volume and balance controls to achieve
   the desired level in each ear.  If distortion occurs, you
   may have to reduce the volume level controls on the
   synthesizer and/or transcriber.
