Ramsey Electronics SHA2 - Manual (Page 20)

SHA2 • 20
You can set the left and right channels independently of each other. H1
controls the right channel of the stereo output and H2 controls the left channel.
Pin 1 on both H1 and H2 is marked by a triangle. By placing a jumper block
between pins 1 and 2 of H1 and H2, the buffered output follows the input
exactly. Whatever you have coming in on the audio input is what will be sent
out on J2. Placing the jumper block between pins 2 and 3 of H1 and H2
causes the buffered output to have the same tone controls applied to it as the
headphone output. You can put the jumper block on H1 and not H2, on H2
and not H1, etc. so that one channel would have tone control applied to it and
the other would exactly follow the input. It’s all up to you.
Once you have the jumpers set, try plugging the buffered output into the line
level input on a piece of equipment and make sure it’s working correctly. If you
have the tone controls set and have H1 and H2 jumpered for it you should be
able to hear that the original line level source has been changed and now
matches what you’re hearing through the headphones.
That’s about it. You’re ready to start using your SHA2.
One last thought about the buffered output. You can use it to daisy chain more
than one SHA2 so that all headphone outputs on the chain are hearing the
same source. Simply plug the buffered output of the first SHA2 into the line
level input of the second SHA2. Now you have 4 headphone jacks all on the
same “channel”, all hearing the same audio. Think of the possibilities for long
car trips. A portable DVD player with a line level audio output, 2 to 4 children
in the back of a minivan all happily listening to a movie on their own
headphones, peace and quiet for the driver. Sounds lovely, doesn’t it?
We’re sure you’ll come up with other uses for your SHA2, such as plugging
the line level output of your Bose radio into it so that you can listen on
headphones. Or plugging a line level audio source into your Ramsey FM
transmitter through an SHA2 so that you can monitor the broadcast without
having to tune in an FM radio. And there are probably many other applications
that we haven’t even thought of yet. Let us know if you come up with
something interesting, ok?
