Configuring the digital surround controller using a computer

Either option can be set to Last valid to leave the corresponding
setting unchanged when you select the source. You would
usually set Video Input to Last valid for audio sources such as
CD, Radio, Tape1, and Tape2.
You can create a source with Main input set to Last valid if you
want it to change some other aspect of the current source, such
as its DSP preset, without changing the selected input.
If you have specified a digital input for the main audio input:
● Specify the precision for the source by choosing an option
from the Precision drop-down menu.
All CDs and laserdiscs are currently 16-bits. The 518 provides
24-bits. If in doubt choose 24-bit.
The Extra analogue input drop-down menu allows you to select
an extra analogue input for copying digital sources. Select this if
your digital source also provides an analogue output, and you
want to make analogue recordings from it.
If you have chosen an analogue input for the main audio input:
● Specify the sensitivity of the input by choosing an appropriate
option from the Sensitivity drop-down menu.
Note that you can also adjust the sensitivity of any analogue
source interactively, using Gain/Sub mode. See To adjust the
sensitivity of analogue sources, page 76.
