With CD BEHAVIOR you can tell OPUS what to do in regards to CDs that you put in, espe-
cially in view of making it easier for you if you are doing a lot of importing:
• PLAY WHILE IMPORTING: Listen to the CD while importing or not.
• ON AUDIO CD INSERT: Decide whether on inserting a music CD it should always be
imported (IMPORT SONGS) and ejected after the import is completed (EJECT AFTER
IMPORT).
• CD RECOGNITION: Depending on the type of CDs you are inserting, AUDIO CDs or
DATA CDs, you can set this parameter. We suggest you leave the setting at AUTO-
MATIC, which should work best across all your CDs.
Analog recording
This feature is disabled on the OPUS N°5.
Burning to CD
You have a number of options when burning a CD:
• DISC FORMAT: Choose in which format you would like the end product, likely de-
pending on where the CD is to be used:
• AUDIO CD: This is the standard quality CD format that any CD player should be
able to read, and OPUS recodes any files chosen to the CD-A file format.
• MP3 CD: Here the result is a CD with MP3 files on it, files chosen that are not in
the MP3 format are ignored.
• DATA CD: In this case a CD is generated which computers can read and where
the audio files are left in the form they are in, e.g. in FLAC, MP3 or WAV form.
For MP3 and Data CDs you can further determine that folders with artist and album
titles are created during the burning process.
• SPEED: The Speed option lets you choose between a safer or faster burning. The
setting SECURE leads to an 8x speed and the best quality burn, and the setting FAST
burns at up to 24x speed.
• GAP BETWEEN SONGS: You can define the length of the gaps between songs in
seconds.
• CREATE CD-TEXT: Some CD players can read tag information off CDs, and if you
set this option to on, you will be embedding the tag information that belongs to your
audio files onto the burned CD-R.
All CDs that you create will be remembered by your OPUS for the future, i.e. their tag infor-
mation is added to the internal CD reference database so that album title and other fields
will show up whenever you re-insert the CD.
Massaging your music output with dynamic range compression
Under natural conditions, ears can hear soft sounds in a quiet environment, but not in a
noisy environment. E.g. in a moving car background noise can overpower soft sounds, but
simply turning up the volume would make the loud parts uncomfortably loud. Dynamic
range compression is a process that manipulates the dynamic range of an audio signal by
increasing the volume of both the soft and loud parts of sound, though the soft parts are
increased more than the loud parts. The overall effect is that a compressor makes softer
sounds relatively louder and louder sounds seem relatively softer in comparison. So should
you be using the OPUS in a noisy environment, this feature is great for you, it is most often
used in public areas, like restaurants, hotels, etc., to accommodate the guests.
