HHB comm CDR800 - Manual (Page 3)

tomatically generates a track number on
the CD. It makes sense to prepare a DAT
master, including all of the index points
you desire, before making a CD–R.
The CDR–800 will also copy other
digital sources the same way, including
MiniDisc, Digital Compact Cassette, and
CD, using the AL–SYNC mode. There is
also a 1–SYNC mode that allows auto-
matic copying of 1 track from any of the
above digital sources. A f ter the one
track of the original has been recorded,
the recording process stops. You can
add additional tracks to your recording,
using this mode, until the CD–R is filled
to capacity.
The CDR–800 also allows manual
copying of analog or digital sources, one
track at a time. During manual record-
ing, the CDR–800’s REC LEVEL and REC
BALANCE function the same as on any
other recording device. You can record
an individual track, stop, and continue at
a later time. If you manually record a sin-
gle track, a process called “fixation” au-
tomatically takes place before and after
the track is recording. During fixation,
the lead-in and lead-out information for
that track is written.
When you have finished recording a
CD, you must perform a process called
“finalization,” which allows the CD–R to
be played on any conventional CD play-
er. During this process, the absolute lead-
in and lead-out information for the entire
disc, and the table of contents, are writ-
ten to the CD, along with a code that pre-
vents further recording on the disc.
Once you have finished recording a disc,
press the FINALIZE button. After a few
seconds of setup, the display will indi-
cate a time of 4:03 or 4:07, depending
on the length of the recording. This is
the amount of time it will take to finalize
the disc.
Now, press the PAUSE button to begin
the process. The time display begins
counting down—when it reaches 0:00,
the process is complete, and the CD–R
may be played in any CD player. The
CDR–800 has a SKIP–ID function that
can be used during finalization. This
function allows you to effectively elimi-
nate any unwanted tracks on your CD
af ter it has been recorded. Suitably
equipped CD players will then ignore
those tracks during playback.
The CDR–800 is supplied with a re-
mote control that duplicates the func-
tions of the front-panel controls. You
must use the remote to enter track num-
bers for CD playback—numeric buttons
for track selection are not included on
the main chassis of the CDR–800. Re-
mote-control operation can be defeated
with a DIP switch on the rear panel. The
rear panel of the CDR–800 is also fitted
with an 8-pin DIN Parallel Remote sock-
et, which allows you to construct your
own wired remote control, duplicating
PLAY, PAUSE, RECORD, STOP, MANUAL
TR ACK NO., WRITE, and the t wo
TR ACK SEARCH BUTTONS. A connec-
tion diagram is included in the CDR–800
manual.
Circuitry and Construction
As Photo 4 shows, the CDR–800 is
packed with circuitry. There are no less
than 13 PC boards in the CDR–800, vary-
ing in size from large servo and audio
digital boards to several ver y small
boards, including the headphone amp.
Two power transformers are used, one
for the audio and digital circuitry, and an-
other dedicated to the servo. Like most
products of Far East origin, the CDR–800
uses standard 3-terminal IC regulators for
the power supplies. Several of these reg-
ulators are located on the two power-
supply PC boards, but the analog/digital
board and the servo board each house a
pair of local IC regulators.
