Sound Card Setup
Quick Start Guides can be found in our Knowledge Base for the Delta-44 and the Edirol FA-66.
Otherwise, if using a consumer sound card, it may be necessary to do some more software setup. Open the
software and look at the Audio Tab on the Setup Form. With the radio powered on and running, adjust the
Line In Gain down from 50 until the noise floor just begins to rise. Adjust the value back up 3-4 and call
that your optimal Line In gain. If the noise floor never rises, use a value of ā1ā. This will give you the least
noise due to the sound card yielding more room for larger signals. This translates into higher dynamic
range. Note that making any changes to the Line In gain will invalidate the calibration. So make sure to
calibrate after doing this procedure (see below).
