Electric Guitar Through Effects Rack
You can also plug an electric guitar into an effects rack, then send the output of the rack to
the sound card's input, as shown in the following diagram:
This diagram assumes that the output of the rack is at line level. If it is at pro level instead
(+4 dB), and your card does not accept a +4 db input, you will need to attenuate (lower) the F/
X rack's signal. To do this, use a mixer between the rack's output and the Y-adapter. If the
rack has only a mono output, a 1/4" mono to 1/8" stereo adapter should be used instead of a Y-
adapter.
If you want to connect a guitar amplifier's direct output to the sound card, you should base
your setup on this example.
