INTRODUCTION
Thank you for purchasing the Roland DM-80 hard disk recorder. The
DM-80 is a multi-track disk recording workstation offering state of the
art performance and features, at a ground-breaking price. The basic
model (DM-80-4) can record and play back any combination of four
tracks simultaneously. The expanded DM-80-8 can record and play
back any combination of eight tracks simultaneously.
The DM-80 is a full-featured professional system including multiple
digital & analog I/Os, built-in disk drives, real time sample rate
conversion, and optical disk support.
Utilizing the resources of one of the leaders in digital sound
technology,
the
Roland
DM-80
system
brings
this
leading-edge
performance and reliability to a new low price point.
Recording time is limited to the amount of hard disk storage. One SCSI
bus and disk(s) is required per 4 tracks of audio. The recording format
is 16 bits linear; sample rates of 32, 44.1, and 48 kHz may be selected.
A 100 megabyte hard disk will allow roughly 18 monophonic minutes
of recording time at the CD rate of 44.1 kHz. A single recording or
project may be spread over multiple hard disks for even longer
recording times.
On playback, the DM-80 uses a trick borrowed from MIDI sequencers
and drum machines, where any one recorded section may be re-used
any number of times. A re-used section may have different start, stop,
fade in, and fade out times than the original use of the section. Also,
when a track is silent, no disk memory is used. Therefore, the total
playback time may be much longer than the total recorded time.
FEATURES
16-bit multi-track hard disk recording.
Record and play back any combination of four tracks simultaneously
(DM-80-4).
Expansion to eight track capability (DM-80-8). One SCSI bus and disk
per 4 tracks of audio.
16 bit linear recording format; sample rates of 32, 44.1, and 48 kHz
available.
Each 100 megabyte hard disk allows approximately 18 track minutes of
recording time at 44.1 kHz.
Recordings can be spread over multiple disks for longer recording
times.

PRECAUTIONS
POWER SUPPLY
LOCATION
CARE
OTHER
COPYRIGHT
Be sure to use only the correct AC voltage. Do not connect the DM-80 to
the same circuit as devices which produce electrical noise (motors, lighting
dimmers, etc.) or devices which consume large amounts of power (heaters,
air conditioners, etc.)
Avoid damaging the power cord; do not step on it or place heavy objects on it.
For best performance from the DM-80's hard disk be sure to install the DM-
80 rack mount unit in a solid, level location, in an area free from excess
vibration or movement.
Operating the DM-80 near devices containing large power transformers
(e.g. power amplifiers) may induce hum.
If the room suddenly changes temperature, or if the DM-80 is brought from a
cold location into a warm room, condensation may form on the hard disk or
other components, which can cause damage. In this situation, wait for one hour
or more for the DM-80 to adjust to the new temperature before operating.
Do not subject the unit to temperature extremes (e.g. direct sunlight in an
enclosed vehicle). Avoid storing or using the unit in dusty or humid areas,
or areas that are subject to high vibration levels.
This unit may interfere with radio and television reception. Do not use this
unit in the vicinity of such receivers.
For everyday cleaning, wipe the unit with a soft dry cloth, or one that as
been slightly dampened with water. To remove stubborn dirt use a mild
neutral detergent. Afterwards be sure to wipe the unit thoroughly with a
soft, dry cloth.
Never use benzene, thinner, alcohol or solvents of any kind to avoid the
risk of discoloration or deformation.
Do not subject the DM-80 to strong shocks.
Do not press hard on the display or allow it to be hit.
The DM-80 may produce some heat when operating normally.
Always turn off the power to all equipment before making connections
with other devices.
Do not allow objects or liquids of any kind to penetrate the unit. In the
event of such an occurrence, discontinue use immediately. Contact
qualified service personne! as soon as possible.
Should a malfunction occur (or if you suspect there is a problem)
discontinue use immediately. Contact qualified personnel immediately.

When recording from Compact Discs or other sources, please respect
copyright laws. Refrain from copying and/or distributing copyrighted
material in any way, without the approval of the copyright holder.
A hard disk is a very delicate storage device. Do not subject it to shock
or vibration of any kind. Be especially careful not to move or bump
the unit while the power is on.
Shut down the DM-80 by using the Shut Down command before
turning off the power. After shutting down the unit, wait until the drive
has stopped rotating, about 30 seconds, before moving the unit.
It will take several minutes for the hard disk to “boot up” after the
power is turned on.
Never turn off the power while the hard disk is being accessed (while
any of the hard disk indicators are lit).
if the cooling fan is obstructed, overheating may cause data to be lost
or other malfunctions to occur.
When handling external hard disks, etc., refer to the manual for each device.
Roland cannot be responsible for any data lost while using the DM-80.
It is strongly suggested that you frequently make backup copies of your
hard disk data.
TRANSPORTATION = Always pack the DM-80 in its shipping box or shock-mount rack case.
Make sure the drives have stopped rotating before moving the unit.
Since disk drives are quite sensitive to vibration, take great precautions
to protect the unit from shock and other vibration.
CONVENTIONS
SYSTEM
CONFIGURATION ~The DM-80 is available in two versions: the DM-80-4 with four tracks
and a single 100MB hard disk drive; and the DM-80-8 with eight tracks
and two 100MB hard disk drives.
TRACK MINUTES = Any mention of recording time refers to track minutes. Track minutes is
the total number of minutes available for recording on one track. 10
track minutes means 10 minutes of mono recording, 5 minutes of
stereo recording or 2.5 minutes of four track recording. Remember that
recording time is utilized differently in a disk system compared to tape,
resulting quite often in substantially longer actual project lengths.

HOW THE DM-80 WORKS
The DM-80 is possible because of a series of technological
advancements. The most important of these are Digital Recording and
Disk Recording.
DIGITAL RECORDING
Digital recording, popularized by the advent of the Compact Disc,
records sound by storing a series of numbers — a series of digital
snapshots. These snapshots are then played back in series, much a like
a motion picture. The number of snapshots per second is called the
sampling rate. In a CD the sampling rate is 44.1 kHz, which means
there are 44100 sonic snapshots every second. A DAT recorder has
rates of 48 kHz, 44.1 kHz and 32 kHz. The DM-80 can record and
playback at these same rates. The higher the rate, the higher the
frequency response.

DISK RECORDING
Disk
recording
means
storing
digital
recordings
on
a
disk
rather
than
a
tape.
Why
is
this
important?
Because
it
makes
possible
random
access.
Random
access
enables
your
recording
to
be
played
in
any
order
you
like.
This
means
any
note,
measure,
background
vocal,
or
even
the
entire
project
can
be
played
back
instantly,
without
having
to
rewind
and
fast
forward
a
tape.
This
also
means
any
recording
can
be
played
anywhere
within
the
song
you
like,
just
like
a
MIDI
sequencer
—
except
here
we
are
working
with
complete
digital
recordings.
The
possibilities
are
quite
profound
and
we
encourage
you
to
experiment
and
“push
the
envelope”
of
musical
creativity.
LINEAR TAPE ACCESS:
RANDOM DISK ACCESS:
tEseke8
Another
thing
to
be
considered
is
the
issue
of
the
data
itself.
If
over
44
thousand
samples
per
second sounds
like
a
lot
of
data,
you're
right.
In
fact
ten
seconds
of
digital
audio
represents
about
the
same
amount
of
data
as
the
manual
you
are
holding
in
your
hands
right
now.
So
we
are
talking
about
extremely
!arge
amounts
of
data
moving
in
and
out
of
the
DM-80
at
very
high
speeds.
What
makes
the
DM-80
feasible
is
a
big,
fast
disk
drive.
Floppy
disk?
Way
too
slow,
and
even
if
it
was
fast
enough,
you’d
fill
it
up
after
recording
10
seconds.
Fortunately,
the
kind
of
big,
fast
disk
drives
needed
for
disk
recording
are
now
easily
available.
The
DM-80-4
has
a
100MB
drive
built-in,
and
the
DM-80-8
has
two
100MB
drives.
External
disk
drives
can
also
be
used.

Use
the

may
result
in
