Bright 0
and back to
Bright 7
.
After time-out, a setting of
Bright 0
blanks the display unless the unit is not
locked. Operating any control or locking to a source while in this mode turns the
display back on momentarily.

Phase
– Overall Phase
This option allows you to invert (reverse the phase of) both channels to correct

.
do this:
Press the

- De-Emphasis Behaviour
Recording with high frequency emphasis is a hangover from the days of
recording onto noisy magnetic tapes. To combat tape hiss, the high frequency
part of the music was recorded at a higher level (pre-emphasis). The high
frequency response was corrected at playback by a de-emphasis filter, reducing
the hiss level as well. Digital radio also can use CCITT pre-emphasis, to help
keep the bit rate down.
Some early CDs were recorded with 50/15
µ
s emphasis, but more recent disks
have a flat frequency response. The emphasis used during recording is
encoded in message flags, buried in the data stream. On some disks, these
flags are incorrect, resulting in a bumpy frequency response.
Delius
can apply
de-emphasis for sources with sample rates of 32, 44.1 or 48kS/s – it is not used
for 96kS/s or SACD recordings.
The options available are:
Off
Applies no de-emphasis and ignores message flags.
Auto
Automatically applies the de-emphasis curve indicated by
the message flags in the data stream.
50/15us
Applies 50/15
µ
s de-emphasis curve and ignores
message flags.
CCITT
Applies CCITT J17 de-emphasis curve and ignores
message flags.
To change the
De-Emph
setting, do the following:
do this:
Open the Function Menu and step through until the display shows
DeEmph
.
