Before You Start Recording
• It should be noted that it may be unlawful to
re-record pre-recorded tapes, records, or
discs without the consent of the owner of
copyright in the sound or video recording,
broadcast or cable programme and in any
literary, dramatic, musical, or artistic
embodied therein.
• Tracks of less than 3 seconds cannot be created (or
recorded) in the HDD.
• Each recording is stored as an album in a library.
• The recording level is not affected by the volume.
During recording you can adjust the volume you are
actually listening to without affecting the recording
level.
• While recording, you can hear the Active Hyper Bass
Pro and/or the tone control effect through the speakers
or headphones. However, the playback sound is
recorded without these effects (see page 15).
• While recording, HDD play modes (Album play,
Library play, and Random play) including Repeat play
are temporarily canceled.
How the HDD separates the recorded tracks?
When playing back the recordings in the HDD, you can
move among the tracks. But why?
• When recording from CD:
A track number is assigned automatically at the
beginning of each track. (The playing time of the track
recorded in the HDD may differ from the original
playing time of the track on the CD).
• When recording from the external component
connected to the LINE IN jacks:
Only single track number is assigned.
This means that the HDD will regard the entire
recording as one track. However, if there is a blank of
about 3 seconds or more, the HDD will consider it as a
blank separating 2 tracks and consequently assign
another track number to the latter portion.
To assign a track number manually (except while
recording from CD and while recording with Tuner
Auto Recording), press
SET at the place where you want
to assign a track number.
• You cannot assign track numbers manually while
recording from CD or recording with Tuner Auto
Recording (see page 46).
To assign a track number (in other words, separate a
track) after recording is over, you can use the DIVIDE
function (see page 64).
About the digital formats used for recordings
When recording into the HDD, you can select either linear
PCM or AAC (Advanced Audio Coding) format.
Linear PCM format is the one used for regular audio CD.
Audio signals are recorded without any compression.
On the other hand, AAC is a newly developed audio
compression technology which can eliminate over 90
percent of the original signal data without losing the
brilliance of the original. This unit allows you to select
128 kbps and 96 kbps as a bit rate*
1 .
Allowable recording time differs according to the digital
format used. Assuming that only one format is used for all
the recordings, recording time will be as follows:
• Linear PCM:
About 15 hours* 2
• AAC 128 kbps: About 173 hours* 2
• AAC 96 kbps: About 227 hours* 2
* 1 Bit rate is the average number of bits that one second of audio
data will consume. The unit used is kbps (1024 bits/second). To
get a better audio quality, choose a higher bit rate. The most
popular bit rate for encoding is 128 kbps.
* 2 These values are theoretically calculated when there is no data
recorded. They may differ depending on the recording condition
(see page 82).
About the maximum recording length for one track
You cannot continue recording as a single track if its
recording time exceeds the following times:
• Linear PCM:
About 3 hours.
• AAC 128 kbps/96 kbps: About 24 hours.
Another track number is automatically assigned to the
recorded portion exceeding the maximum length.
About SCMS (Serial Copy Management System)
The HDD built in this unit uses the Serial Copy
Management System which allows only first-generation
digital copies to be made of premastered software such as
regular CDs.
If you try to record from a duplicated CD-R or CD-RW
into the HDD, “SCMS CANNOT COPY / ANALOG REC”
appears in the main display then this unit automatically
selects analog recording.
• If double normal speed recording (PCM x2 REC) or four
times normal speed recording (PCM x4 REC) is selected
for the recording, the recording mode will be
automatically changed to normal speed recording (PCM
x1 REC).
