The buffer allows a mistakenly started recording to be stopped within the fi rst 3s, before
the start of any disc writing actions, and it also ensures that recordings can be made
without loss of music at the start of a track when using synchronized CD recording.
Buffering also permits the use of synchronized starting from analogue sources. This is
done by monitoring the incoming audio signal for the rise in level that indicates the start of
play, after which the fi rst few seconds of music are recovered from the buffer for recording.
The recorder incorporates a digital recording level and balance control that allows manual
adjustments. This can be used to correct variations between individual discs, a valuable
feature if you are making compilations, as it allows you to adjust the volume levels of all
tracks. Digital recording level adjustments can be made easily using the Easy Jog control.
The CDR 770 has three sets of input sockets, allowing easy connection to a wide variety
of audio sources. Both optical and coaxial digital inputs are provided for the highest
quality connection to digital sources, along with standard stereo sockets for connection to
virtually all analogue sources, as well as coaxial digital and analogue outputs.
Like its computer drive counterpart, the CDR 770 can make use of both CD-R and
CD-RW blanks, and the CD-R discs can be played on any other CD player, either on
audio equipment or in a computer system. The CD-RW discs can be replayed on the
CDR 770 and on many of the most recent CD playing decks or drives. If your CD player
is not of recent design, however, it will not be able to read the CD-RW discs.

When the CD system was launched, following the commercial failure (in the United
Kingdom, but not elsewhere) of the earlier laser-disc moving picture system, there was
no form of compression of data used. The whole system was designed with a view to
recording an hour of music on a disc of reasonable size, and the laser scanning system
