Powering up a CBX-D5 System
Some computer systems are a little bit fussy about which devices are switched on first,
especially when a SCSI daisy chain is introduced into the system. As a good rule of
thumb, switch on all connected SCSI devices first, then the computer.
NOTE: While using your CBX-D5 computer music system, do not switch off or
disconnect any device connected in the SCSI chain. Doing so will probably
lead to a system crash and you could loose valuable data.
2 CBX-D5 Terminology
SCSI
Pronounced scuzzy , the Small Computer System Interface is a connection format used for
connecting peripheral devices such as hard disks, printers, scanners, etc., to a computer.
Up to eight SCSI devices can be connected together in a daisy chain including the
controlling computer. Each device is given its own identity number from 0 to 7, this is
called the SCSI ID number.
The CBX-D5, a computer, and a hard disk are all connected as part of a SCSI daisy chain.
The SCSI connection carries audio data between the CBX-D5 and hard disk for recording
and playback, and also control data from the computer to the CBX-D5. The controlling
computer can also access the hard disk to perform basic sound file copy , delete, and backup
type functions. With the necessary software, digital audio data could be transferred
directly to the computer for on-screen waveform editing, etc.
The SCSI standard is quite a robust format, although, some care must be taken when
connecting and setting up SCSI devices. For full details about connecting SCSI hard disk
drives to the CBX-D5 see “Connecting Hard Disk Dri v es” on page13.
Sound files
Just like other types of computer data, digital audio data is stored in files – sound files.
When recording starts, a sound file is created on the hard disk. This sound file can be given
a name, copied, and deleted just like any other computer file.
CBX-D5 Terminology 3CBX-D5 Terminology 3CBX-D5 Terminology 3
AES/EBU format
AES/EBU is a digital interface format established by the AES (Audio Engineering
Society) and EBU (European Broadcasting Union). It is used to transfer digital audio data
between professional digital audio equipment. Usually , two channels of digital audio (left
& right) are carried in one XLR type connection.
Although similar to the CD/DAT format, it is primarily intended for professional usage.
AES/EBU format connections can be found on most professional digital audio equipment
including hard disk recorders, digital mixers, professional DAT recorders, and many
digital VTRs.
CD/DAT format
Similar to the professional AES/EBU format, CD/DAT, or S/PDIF (Son y/Philips Digital
Interface Format) as it is otherwise known, is a digital interface format that is used to
transfer digital audio data between consumer type digital audio equipment such as CD
players, consumer DAT recorders, and the new DCC recorders.
Like the AES/EBU format, two channels of digital audio (left & right) are carried in one
connection, usually a phono/RCA jack type connection. Some MIDI samplers are fitted
with a CD/DAT connection so that sample data can be transferred directly to a DAT
recorder for storage.
Y2 format
Y2 Yamaha format is a digital interface format developed by Yamaha that is used to
transfer digital audio data between Yamaha’s professional digital audio equipment. Two
channels of digital audio (left & right) are carried in one connection, usually an 8-pin DIN
type connection.
Y amaha’s professional digital audio products usually include the AES/EBU and CD/DAT
type formats as well as Y2, and the Y2 format can also be found on some other
manufacturers’ digital audio products. Yamaha’s professional digital audio products that
use Y2 include the DMR8 Digital Mixer/Recorder, DMC1000 Digital Mixing Console,
DRU8 Digital Recorder, and the DMP series of Digital Mixers.

Sampling frequency (REC FREQ)
During the analog to digital conversion process, the level of the analog audio signal is
sampled (measured) many times per second. Each of these sample measurements is then
stored as a 16-bit binary value. For digital to analog conversion (playback), these 16-bit
binary values are used to reconstruct the analog audio signal. The rate at which these
sample measurements take place is called the sampling frequency and you may already
know that the sampling frequency used by CD players is 44.1kHz.
The CBX-D5 can record audio using any one of four sampling frequencies: 48kHz,
44.1kHz, 32kHz, and 22.05kHz. The audio quality (bandwidth) of a digital system is
directly affected by the sampling frequency. Essentially, the audio bandwidth will be
roughly half the chosen sampling frequency . See “Sampling frequenc y (REC FREQ)” on
page 20 for more details.
Word clock
When a number of digital audio devices are connected together and data is digitally
transferred between them, it is essential that the data processing circuits of all devices are
synchronized. To achieve this, one device operates as a word clock master and all other
devices operate as word clock slav es. The frequency of the word clock corresponds
directly to the digital audio data’s sampling frequenc y.
If you only connect two digital audio devices, say the CBX-D5 to a DAT recorder, word
clock setup is quite straight forward and no word clock connections will be required.
Howev er, when three devices are connected, serious thought will need to be given as to
which device is word clock master and how to mak e the w ord clock connections. See
“WORD CLK IN/OUT” on page 28 for more details.
NOTE:
To Host
An 8-pin mini DIN connector that allows direct connection to a computer that is running
CBX-D5 supporting software. This can be used when your computer does not have a
MIDI interface, i.e. MIDI input and output connections. See “TO HOST connection” on
page 30 for more details.
NOTE:
W ord clock signals should not be confused with other synchronizing signals
such as SMPTE timecode and MTC (MIDI Timecode). Although both may
be used in a digital audio system, word clocks are for synchronizing digital
audio data processing circuits such as CPUs, D/A, A/D converters, etc., while
SMPTE and MTC timecodes are for synchronizing audio and video tape
machines, MIDI sequencers, etc., relative to time – hours, minutes, seconds,
and frames.
Not all CBX-D5 supporting music software can use this type of connection,
so please consult your Yamaha dealer before making a purchase.
3 What is the CBX-D5?
The CBX-D5 is a Digital Recording Processor that, when connected to a controlling
computer with supporting software and an external hard disk, provides up to four channels
of CD quality audio recording, processing, and playback.
Computer based
The CBX-D5 is controlled by a computer that is running CBX-D5 supporting software.
All audio data processing takes place inside the CBX-D5, so there is very little demand on
the controlling computer. F or this reason the CBX-D5 can be used with some of the less
powerful, less expensi v e computers such as the Apple Macintosh SE/30, Classic II, and
LC; and the Atari ST/STE. It also leaves the computer free to get on with other jobs such
as processing MIDI sequence data and screen updates.
The CBX-D5, computer, and hard disk are all connected as part of a SCSI daisy chain. The
SCSI connection carries audio data between the CBX-D5 and hard disk for recording and
playback, and also control data from the computer to the CBX-D5. A MIDI connection
between the CBX-D5 and computer carries continuous controller information for
real-time volume, EQ, and pan control of the CBX-D5’s digital mixer.
Four-channel system
The CBX-D5 is a 4-channel system, i.e., 2-channel simultaneous recording and
4-channel playback. Channels can be recorded while other channels playback.
What is the CBX-D5? 5What is the CBX-D5? 5What is the CBX-D5? 5
The CBX-D5 needs about 100Mbytes of hard disk space to record 10 minutes of stereo
digital audio (fs = 44.1kHz). The available recording time can be increased by simply
adding more, or larger hard disk drives to the SCSI daisy chain.
CD quality & editing
The CBX-D5 records audio data at a 16-bit resolution, and with 44.1kHz and 48kHz
sampling frequencies it provides all the sound quality benefits of the Compact Disc format
such as faithful reproduction, low noise, minimal distortion, etc.
Analog input and output signals are processed by 16-bit linear ∆ Σ modulation A/D and
18-bit 8-times oversampling D/A con verters. Analog connections use balanced XLR type
connectors. Digital I/O consists of AES/EBU, CD/DAT, and Y2. Allowing digital audio
data transfer between the CBX-D5 and other digital audio equipment.
As well as the A/D, D/A converters, the CBX-D5 also contains a 4-input, 4-bus, 2-send
digital mixer; a DSP for digital effects; DEQ for real-time EQ control; and sampling
frequency conv erters that allo w recording and playback at differing sampling frequencies.
As well as the sound quality , tw o other benefits of recording with a CBX-D5 system as
opposed to analog tape are, the ability to nondestructively edit recordings and being able
to move audio data relativ e to time, a feature often referred to as audio time slip.
For a listing of some other CBX-D5 features, see “CBX-D5 features” on page 1.
The future
The CBX-D5 is a software dependent device, so with future supporting software it may be
possible to use the CBX-D5 for digital mixing with digital EQ and effects, sampling,
2-track mastering, waveform editing, and multimedia type applications.

Front panel
1 POWER switch
Used to turn the power on and off. Press once to switch on, press again to switch off.
2 SOURCE indicators
Indicates the input selected for recording: AES/EBU, Y2, CD/DAT, or ANALOG. The
source input selection is made by the controlling software.
3 REC FREQ indicators
Indicates the selected sampling frequency for recording: 48kHz, 44.1kHz, 32kHz, and
22.05kHz (analog inputs only). The sampling frequency selection is made by the
controlling software.
4 PB FREQ indicators
Indicates the sampling frequency of the digital audio data that is being output by the
CBX-D5: 48kHz, or 44.1kHz. The playback sampling frequency setting is made by the
controlling software.
When the CBX-D5 is used with an external word clock, the digital outputs will operate at
the same frequency as the external word clock and that frequency will not be indicated by
the “PB FREQ” indicators.
Front panel 9Front panel 9Front panel 9
5 INPUT LEVEL meters
T wo 12-se gment LED bargraphs indicate the le vel of the incoming digital audio when the
input source is set to AES/EBU, CD/DAT, or Y2 (not af fected by the level controls), or the
level of the analog input signals when the input source is set to ANALOG (controlled by
the “ANALOG IN” level controls).
NOTE:
Unlike peak meters on analog equipment that light up approximately 3 ~ 6dB
before signal clipping, CLIP LEDs on digital equipment light up when the
signal has actually clipped. Digital audio signal clipping normally produces
unpleasant distortion, pops, and clicks, so care must be taken when setting
the recording level for analog input signals. See “Recording” on page 20 for
more details.
6 OUTPUT LEVEL meters
Four 12-segment LED bargraphs that indicate the output level of channels 1 ~ 4. The
“CLIP” LED indicates an output level of +17dBm.
NOTE:
Just like the input level meters, lighting an output le vel meter’s “CLIP” LED
should be avoided to pre vent signal distortion. This situation may occur when
two or more CBX-D5 audio channels are mixed, or if excessive EQ is
applied. The CBX-D5 does not have any output level controls, the output
level is set by the controlling software.
7 ANALOG IN LEVEL control
Independent level controls for analog input channels 1 and 2. As well as independent le vel
control, these controls can also be used to balance the left and right channels of a stereo
source connected to the analog inputs.
NOTE:
These controls have no effect on the AES/EBU, CD/DAT, and Y2 digital
inputs and outputs.
8 PHONES VOL
Adjusts the volume level of the headphones.
9 PHONES connection
A stereo 6.35 mm (1/4 inch) phone jack used for connecting a pair of stereo headphones.
All four CBX-D5 audio channels can be monitored – channels 1 and 3 appear in the left
speaker and channels 2 and 4 in the right.

Rear panel
The explanations below are only brief introductions to the CBX-D5’s rear panel
connections. For full details about the inputs and outputs, see “Inputs & Outputs
Explained” on page 26.
1 ANALOG IN 1&2
A pair of female XLR 3-31 type connectors used for inputting analog audio signals. These
are balanced inputs with a nominal input level of +4dBm and a maximum input le v el of
+22dBm. These could be connected to the outputs of a mixer, synthesizer , drum machine,
etc. Microphones, guitars, and equipment with an output level less than –20dBm must first
be connected to a preamplifier, then to the CBX-D5.
NOTE:
When the Analog inputs are used unbalanced, the maximum input level is
reduced to +16dBm.
2 ANALOG OUT 1 ~ 4
Four male XLR 3-32 type connectors used for outputting channels 1 ~ 4 as analog audio
signals. These are balanced outputs with a nominal output level of 0dBm and a maximum
output level of +17dBm. These could be connected to the inputs of a mixer , amplifier , tape
recorder, or DAT recorder.
3 AES/EBU IN 1/2
A female XLR 3-31 type connector for inputting AES/EBU format digital audio. Only one
input connection is required for channels 1 and 2 because the AES/EBU format carries two
signals in one connection. These could be used when recording digital audio data from
professional digital audio equipment such as another hard disk recorder, a digital mixer,
digital recorder, or digital VTR.
Rear panel 11Rear panel 11Rear panel 11
4 AES/EBU OUT 1/2 & 3/4
Two male XLR 3-32 type connectors for outputting AES/EBU format digital audio.
Channels 1 and 2 are output via “OUT 1/2”, and channels 3 and 4 via “OUT 3/4”. These
could be used to transfer digital audio data from the CBX-D5 to professional digital audio
equipment.
5 CD/DAT IN 1/2
A Phono/RCA jack for inputting CD/DAT format digital audio. Channels 1 and 2 are
carried in the same connection. This connection could be connected to the digital output
of a CD player or DAT recorder and allows digital audio recording without multiple D/A,
A/D audio data conversions. Some MIDI samplers are fitted with this type of connection.
In this case your sound samples could be recorded directly to your CBX-D5 system.
6 CD/DAT OUT 1/2
A Phono/RCA jack for outputting CD/DAT format digital audio. Channels 1 and 2 are
carried in the same connection. This could be connected to the digital input of a DAT
recorder or DCC recorder, and allo ws digital audio recording without multiple D/A, A/D
audio data conversions.
NOTE:
It is widely known that the weakest links in a digital audio system are the A/D
and D/A converters. For once the audio has been converted into a digital
form, it is immune from all the problems usually associated with analog
equipment such as distortions and noise. Although the effects of multiple
conversions will be hard to spot, e ven for the best trained ears, it makes sense
that once converted, we try and k eep the audio in a digital form by using these
digital I/O connections wherever possible.
7 Y2 IN 1/2
An 8-pin DIN socket for inputting Y2 Y amaha format digital audio. As with the AES/EBU
and CD/DAT formats, two audio channels are carried in the same connection. This could
be connected to one of Yamaha’s digital audio products such as a DMR8 Digital
Mixer/Recorder, DMC1000 Digital Mixing Console, DRU8 Digital Recorder, SPX1000
Effect Processor , or the DMP series of Digital Mix ers.
8 Y2 OUT 1/2
An 8-pin DIN socket for outputting Y2 Yamaha format digital audio. This could be used
to transfer digital audio data from the CBX-D5 to one of the Yamaha professional digital
audio products listed above. You might not own one of these products yourself, but you
may need to transfer some of your audio data to a recording studio that does.
9 WORD CLK IN/OUT
Two BNC type connectors for inputting and outputting word clock signals. A common
word clock signal is used to synchronize data processing circuits when a number of digital
audio devices are connected together . F or a full description of ho w and when to use these
connections, see “WORD CLK IN/OUT” on page 28.
12 Chapter 4 : Controls & Connections12 Chapter 4 : Controls & Connections12 Chapter 4 : Controls & Connections
0 MIDI IN
The CBX-D5 receives MIDI control data from the computer via this connection. To
prevent the CBX-D5’s control data being delayed by other MIDI devices, the CBX-D5
should be the first device connected to your computer . Other MIDI devices should then be
connected to the CBX-D5’s MIDI THRU connection.
If your computer’s MIDI interf ace has tw o or three MIDI outputs, dedicate one for use
with the CBX-D5.
NOTE:
Although not usually a problem on a small MIDI system, when more than
three MIDI devices are daisy chained together using MIDI IN and THRU
connections, MIDI data can sometimes be delayed, especially if you transmit
a lot of continuous controller data such as pitch bend or modulation wheel. If
MIDI delays do become a problem, use a MIDI THRU Box to distribute the
MIDI signal to each MIDI device.
A MIDI OUT
When the CBX-D5 is being used as a MIDI interface, that is, a direct connection to a
computer via the To Host connection, MIDI data from the computer is output to other
MIDI devices from this connection. Also used for MIDI bulk dump.
NOTE:
The operation of the MIDI IN and MIDI OUT connections varies depending
on the position of the CBX-D5’s Host select switch. See “TO HOST
connection” on page 30 for full details.
B MIDI THRU
MIDI data appearing at the MIDI IN connection is buffered, then output from this
connection. In other words, all MIDI data appearing at the MIDI IN connector is output to
the MIDI THRU connector unaf fected by the CBX-D5.
C TO HOST connector
An 8-pin mini DIN connector that allows direct connection to a computer that is running
CBX-D5 supporting software. This can be used when your computer does not have a
MIDI interface, i.e., MIDI input and output connections. See “TO HOST connection” on
page 30 for more details.
D TO HOST select switch
This switch setting depends on the type of computer connected to the “TO HOST”
connector. See “TO HOST connection” on page 30 for full details.
E SCSI connectors
T wo 50-way Amphenol type connectors used to connect the CBX-D5 into the SCSI daisy
chain.
F SCSI ID selector
A thumb wheel type switch used to set the SCSI ID number of the CBX-D5. See “SCSI
ID setting” on page 16 for more details.
G Power inlet
A 3-pin power inlet socket. Connect the supplied power cable to this sock et, then plug the
other end of the cable into an AC receptacle of the correct type.
5 Connecting Hard Disk Drives
Before connecting a hard disk drive, read through this chapter to familiarize yourself with
SCSI and how a SCSI daisy chain should be setup.
What type of hard disk?
If you don’t already have a hard disk or are thinking of b uying a larger one, see the supplied
card for a listing of recommended disk drives.
Hard disk size
The following table shows approximate a vailable recording times for v arious sizes of hard
disk. A vailable recording times are shown for all of the CBX-D5’s sampling frequencies,
and as you can see, with a higher sampling frequency – less time is available. This is
because using a high sampling frequency produces much more digital data, which means
a bigger sound file. See “Sampling frequency (REC FREQ)” on page 20 for more details
about selecting a sampling frequency.

Although it is doubtful that you will ever buy a hard disk smaller than 40MB for use with
the CBX-D5, the values below 40MB will be useful for checking the remaining record
time that is available on a hard disk that already contains some sound files.

Choosing a hard disk
If you plan to buy a hard disk that is not listed on the supplied card, the following
specifications should be checked first.
Specification Check Notes
Is it compatible with your computer?
Does it have two SCSI connectors? You need two to continue the SCSI daisy chain.
Are the SCSI connectors 25-pin
D-SUB, or 50-way Amphenol?
Are the SCSI cables supplied? If not, you will need to purchase them separately.
Can the SCSI ID be set from 0 ~ 7? (for
Macintosh you only need 0 ~ 6)
Does it have internal or external
termination?
Access Time?
Data Transfer Rate?
Maybe it is advertised as compatible, or your
dealer recommends it.
Macintosh computers are fitted with a 25-pin
D-SUB connector, while most other SCSI devices
have a 50-way Amphenol connector.
If not, it might clash with another device’s ID, in
which case you may have to rearrange the ID
numbers of some other SCSI devices in the
chain.
External terminators are normally connected to
the rear of the SCSI device. If the device has an
internal terminator, make sure it can be switched
off so that any device can be positioned at the
end of the SCSI daisy chain.
Measured in milliseconds, this is an indication of
how fast data from different areas of the disk can
be retrieved. The maximum we recommend is
30ms. An access time slower than this may affect
the performance of the CBX-D5.
Usually measured in Megabits per second
(Mbit/s), this shows how fast data can be written
to and read from the hard disk. The minimum we
recommend is 16Mbits/s. A transfer rate less than
this may affect the performance of the CBX-D5.
SCSI
For an general introduction to SCSI, see “SCSI” on page 3.
Setting up a SCSI daisy chain requires a little more than just making connections. SCSI
devices require ID numbers and the daisy chain must be terminated correctly. These are
explained in the following three sections, “SCSI cables”, “SCSI ID setting”, and “SCSI
termination”.
When using a SCSI daisy chain, the following points should be borne in mind.
• Allocate each device its own SCSI ID number.
• Terminate the SCSI bus correctly.
• Use quality cables and keep the length down.
• Use the little wire clips (or screws) on a SCSI connector to fasten the cable plugs
securely.
• All devices connected in the daisy chain must be switched on to use the system.
• Never switch off, or disconnect a device once the system has been switched on.
NOTE:
Switch off all your equipment before making any SCSI connections.
SCSI cables
Most SCSI devices are supplied with a SCSI cable, but if you need to b uy one, make sure
that it is designed for SCSI usage and that the connecters on either end of the cable are
correct for your application.
Cable length is an important issue, but it’s not the length of each individual SCSI cable,
it’s the total length of the SCSI daisy chain that must not e xceed 6m (20ft).
SCSI cables 15SCSI cables 15SCSI cables 15
Total length of SCSI daisy chain must not exceed 6m (20ft)
Computer connection
Apple Macintosh
Apple Macintosh computers use a 25-pin D-SUB connector for the SCSI port, so use a
25-pin D-SUB to 50-way Amphenol type SCSI cable, usually supplied with an external
Macintosh hard disk drive.
Atari ST/STE
For Atari ST/STE computers, a Steinberg SCSI adaptor is required. This should be
connected to the Atari ST/STE’s “HARD DISK” port (DMA) using a 19-pin DSUB to
19-pin DSUB cable. An external hard disk drive can then be connected to the SCSI
adaptor’s SCSI connector using a 50-w ay to 25-pin SCSI cable.
NOTE:
Some Atari ST/STE hard disk drives already contain a SCSI adaptor,
however, they cannot be used as a substitute for the Steinberg adaptor.

CBX-D5HARD
Although it is possible to use just one external hard disk, it is highly recommended, for the
sake of data integrity, that you use at least two external hard disks: one disk for your
computer software and data such as Cubase Audio, MIDI song files, etc., and the other disk
purely for recording CBX-D5 sound files.
Atari TT
The Atari TT has a SCSI connection built-in, so a SCSI hard disk drive can be connected
directly .
Atari TT computers are fitted with an internal hard disk as standard. The internal disk
should be used for your computer software and data such as Cubase Audio, MIDI song
files, etc., and an external hard disk should be used purely for recording CBX-D5 sound
files. An external hard disk must be used with an Atari TT, because it supplies the
termination power that is required by the SCSI bus.
IBM PC/AT compatible
For an IBM PC/AT compatible computer, a SCSI adaptor card is required. This should be
installed into one of the computer’s internal e xpansion slots.

SCSI ID setting
The SCSI bus is a parallel type connection, and data on the bus is available to all devices.
Howev er, communication will usually be between two devices only, so each device is
allocated an ID number, like an address number. In this way , only the device with the ID
number that is specified in the data will actually read and respond to the data.
If two devices share the same ID number , the system will probably crash, so make sure that
each device has its own ID number. SCSI devices usually have a DIP switch or, like the
CBX-D5, a thumb wheel switch for ID setting. Refer to the instructions supplied with your
particular SCSI device.

SCSI termination
Unlike audio signals, digital signals only have two values: high and low (+5V and 0V).
When no data is being transmitted, it is important that SCSI bus lines are kept in the high
state (+5V), so that when data is transmitted there is a clear distinction between high and
low pulses and the data is transferred without error. To achieve this, a device known as a
SCSI terminator is connected in the SCSI daisy chain. A terminator is usually fitted to the
last device in the chain.

If the SCSI daisy chain is not terminated correctly, numerous problems
including data corruption, system crashes, and intermittent glitches can
occur. If you have just set up your SCSI daisy chain or have added a new
SCSI device to it and it is not working as it should, check that the SCSI daisy
chain is terminated correctly . If the problem persists, try connecting the SCSI
devices in a different order.
18 Chapter 6 : Working with Hard Disks18 Chapter 6 : Working with Hard Disks18 Chapter 6 : Working with Hard Disks
6 Working with Hard Disks
After connecting your hard disk, setting the SCSI ID, and installing the SCSI terminator,
you will need to format the hard disk before it can be used. If you have already powered
up your system you will notice that there isn’t a disk icon representing the new disk dri ve
on the desktop. This is because your computer could not mount the hard disk during
boot-up, due to it not being formatted.
Formatting
Most SCSI hard disks are supplied with their own disk formatting software, so please refer
to the hard disk’s Manual, and format the disk as specified.
Before disk formatting begins you will probably be asked to supply the SCSI ID of the
hard disk and maybe the required interleave value. The SCSI ID will be the number that
you set on that hard disk using its SCSI ID DIP switch or thumb wheel switch. If you have
to specify an interleave value, check the hard disk’s Manual. Also see the “Adding SCSI
disk drives” section of your computer manual.
When the disk has been formatted correctly and any supplied hard disk driver softw are has
been installed, a disk icon should appear on your computer’s desktop.
Sound file management
By double clicking on the disk’s icon you will be able to access sound files stored on the
disk. Sound files can be copied, deleted, size checked, etc., using the same menu
commands that you would use for your other computer files.
Sound file backup
Because the CBX-D5’s sound files can be managed just lik e your other computer files,
sound files can be backed up in much the same way using data compression and backup
utilities. Howev er, due to the relatively large size of sound files, floppy disks are not the
most effectiv e backup media. Remo vable hard disks and magneto optical disks are well
suited to this task and commonly available sizes include 44MB, 88MB, 128MB, and
650MB.
Another backup option is to digitally transfer your sound files to a DAT recorder. Then, if
you want them again in the future, just record them back to the CBX-D5.
Computer utilities
There are many computer utilities and desk accessories available for managing files and
hard disks such as a “file squashers”, “auto savers”, “hard disk size doublers”, etc. If you
choose to use a utility to work along side the CBX-D5, YOU DO SO AT YOUR OWN
RISK and no responsibility can be claimed for lost data, system crashes, and hardware
damage.
The CBX-D5 is designed to work with the software described in the System Setup Guide,
why risk losing your valuable audio data by using a “super disk space doubler”, or
“real-time data compressor”?
