1-1 Features
The MDS-B5 is a MiniDisc deck for professional use
in any kind of broadcasting, announcements, or
program production.
1-1-1 Features of the MiniDisc
ATRAC (Adaptive Transform Acoustic
Coding) data compression technology
By eliminating inaudible sound data to obtain a
compression ratio of 1:5, ATRAC data compression
technology enables the recording of sound information
of almost the same quality and quantity as a CD, but
on a smaller disc.
74 minutes of playback or recording
A single MD can be used to play back or record up to
74 minutes of sound information. In monoaural mode,
you can record and play back up to 148 minutes.
Direct track access
You can use the supplied wire-connected remote
controller or an IBM keyboard (not supplied) to
directly access any of the MD’s 255 tracks without the
long cueing time required for tape.
Various playback functions
The MDS-B5’s various playback functions include
repeat playback, programmed playback, and random
playback. You can also vary the playback speed
between ±12.5% of the normal speed.
Multiple editing functions
The MDS-B5’s editing functions allow you to divide,
combine, and move tracks on the MD. You can use
the rehearsal function to precisely position edit points
on a track as you monitor the sound.
Unlike tracks on an analog cassette or DAT tape,
specific MD tracks or an entire MD can be erased
instantly.
Text entry
You can use the supplied wire-connected remote
controller or an IBM keyboard to enter titles for
recorded discs and tracks. Title data, which can total
1,792 characters per disc, appear in the display
window during playback.
Durability
Because MDs use a non-contact system like compact
discs, they are superior to cassette tape in durability.
1-1-2 Operational Features
Direct ATRAC data copy function
Multiple MDS-B5 decks can be daisy chained through
the DIRECT DUPLICATION LINK connectors,
allowing ATRAC compression data to be copied about
four times faster than normal dubbing speed. Up to ten
MDS-B5 decks can be daisy chained. When using this
function, the character information on the disc will
also be copied.
Instant playback function
The MDS-B5 can store the first part of up to 10
selected tracks into memory in order to begin instant
playback.
Two cueing modes
You can use the A.MODE button to select the
following two cueing modes.
AUTO PAUSE mode
AUTO PAUSE mode pauses the MD deck at the
beginning of a track, then starts playback when you
press the PLAY/PAUSE button. Use this mode to pre-
cue tracks during on-air broadcasting with multiple
MD decks.
