When a digital audio recorder is connect-
ed to the Digital Audio Outputs gi,
you are able to record the digital signal
using a CD-R, MiniDisc or other digital
recording system.
NOTES:
• The digital outputs are active only
when a digital signal is present, and
they do not convert an analog input to
a digital signal, or change the format
of the digital signal. In addition, the
digital recorder must be compatible
with the output signal. For example,
the PCM digital input from a CD player
may be recorded on a CD-R or
MiniDisc, but Dolby Digital or DTS
signals may not.

Normal output level adjustment for the
AVR580 is established using the test tone,
as outlined on pages 27 – 29. In some
cases, however, it may be desirable to
adjust the output levels using program

you are familiar with. Additionally, the
output level for the subwoofer can only
be adjusted using this procedure.
To adjust the output levels using program
material, first set the reference volume for
the front left and front right channels
using the Volume Control ı
If you are using a disc with test signals
or an external signal generator as the
source from which to trim the output lev-
els, you may use the EzSet feature of the
remote to guide you to the correct SPL
level. To use the remote for this purpose,
