950,000yen(1991 release) |
The business-use recorder announced as a
compact-disk recorder of No. 1 of a Marantz.
In a sound-recording part,
1 bit of audio signals of an analog are changed into a digital signal by an
analog-to-digital converter, are changed by the encoder of cross interleaved
Reed-Solomon code and EFM, and are sent to a CD-Recordable mechanism. Moreover,
since a digital signal is direct changed by an encoder, a register of Digital to
Digital is possible for it.
In addition to the functionality to read the
signal for a play, the CD-Recordable mechanism block carries the functionality
for a register. The functionality for changing a laser power especially by
reading and a register and the electronics for the signal decryption from the
preform track of a CD-Recordable disk and a rotational frequency control
accompany.
system-application-architecture7350 which is a digital analog
converter of a bit stream scheme is carried in the D-A-conversion part.
Moreover, the robustness is improved by adopting quality parts, such as a
die-casting chassis with the high vibration suppression effect.
The
automatic power calibration which sets up a laser power required for a disk
register automatically as a sound-recording functionality using the PCM area of
a CD-Recordable disk,It is the automatic track increment on which subsequent
music will increase and record a track number automatically if there is a
soundless part of regulation time,Manual track placing which sets up the
separation of a track by a manual without judging automatically,The synchro
recording functionality which can do a synchro sound recording by the D BUS
remote connection of an automatic space mute, and a Marantz/Philips which makes
the silent space for about 3 seconds between tracks automatically is carried.
As a play functionality, the special-NetWare-program play, a shuffle
play and a repeat play, and the auto scan functionality are carried.
Moreover, when playing the CD-Recordable disk which has not been fixed
and raised, to the unnecessary fraction of the recorded signal, it points
so that it may skip, and the skip function which treats the fraction as
what not existing, and the un-skip functionality to revive the skipped
fraction are carried.
Wireless remote control is attached.
