Powering up a CBX-D3 System
Some computers are particular about the order in which devices are powered up. It is
generally best to switch on all peripheral SCSI devices before turning on the computer.
Downloading the System Software
Immediately following power-on, the CBX-D3 must download system data from the
computer. The 48kHz LED blinks to indicate that download is not yet completed.
CBX-D3 applications perform the download automatically. If you are working with a
CBX-D5 application, you will need to run the download yourself using a “System
Downloader” program, available on request from your Yamaha CBX-D3 dealer.

SCSI
SCSI (pronounced “scuzzy”) stands for Small Computer System Interface. The SCSI is a
standard format for connecting a computer to peripheral devices such as hard disks,
printers, and scanners. Devices are connected in a daisy chain, with each device (including
the computer) identified by a SCSI ID between 0 and 7.
Your CBX-D3, your computer, and your hard disk are connected together in a SCSI daisy
chain. The CBX-D3 uses the SCSI connection to transmit audio data to or from the hard
disk for recording or playback. The computer uses the connection to send control data to
the CBX-D3, and to perform copy, delete, and backup operations on the hard disk. With
appropriate software, it is also possible to transfer digital audio data directly to your
computer for onscreen waveform editing or other processing.
Although the SCSI standard is fairly robust, some care must be taken when connecting and
setting up the devices. For details about how to connect hard disk drives, refer to page 10.
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. Sound files can be named,
copied, or deleted just like any other computer files.
Sampling frequency
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. CD players use a sampling frequency of 44.1kHz.
The CBX-D3 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. Refer to the discussion of sampling frequency
in the chapter on “Recording” (see page 16) for additional details.

3 What is the CBX-D3?
The CBX-D3 is a digital recording processor. When connected to a controlling computer
with supporting software and a SCSI hard disk, the CBX-D3 provides up to four channels
of CD-quality audio recording, processing, and playback.
Computer based
The CBX-D3 is controlled by a computer that is running CBX-D3 supporting software.
All audio data processing takes place inside the CBX-D3, so there is very little demand on
the controlling computer. For this reason the CBX-D3 can be used even with relatively less
powerful, inexpensive computers. The CBX-D3 leaves the computer free to get on with
other jobs such as processing of MIDI sequence data and screen updates.
The CBX-D3 is connected to your computer and hard disk by SCSI. It is also connected
to the computer by MIDI cables. The SCSI connection supplies control data from the
computer, and transfers audio data to or from the hard disk for recording or playback. The
MIDI connection carries real-time volume data, synchronization clock, playback speed
data, and playback and recording start/stop signals.
Four-channel system
The CBX-D3 is a four-channel system, providing two channels of simultaneous recording
and four channels of playback. Two channels can be recording while the other two are
playing back.
The CBX-D3 requires about 100 megabytes of free hard-disk space to record 10 minutes
of stereo digital audio at a sampling frequency of 44.1kHz. You can increase the available
recording time by changing to a larger disk or adding more disks to the SCSI chain.
CD quality & editing
The CBX-D3 records audio data in 16-bit resolution. Recording quality at sampling
frequencies of 44.1 and 48kHz is at CD level, with true reproduction, low noise, and
minimal distortion.

Two 3-segment LED bargraphs indicating the audio input levels. You can adjust the input
levels by turning the INPUT LEVEL control dials.
8
OUTPUT MONITOR indicators
Four variable-brightness LEDs. Each LED indicates the output level of the corresponding
channel. The LED gets gradually brighter as the level rises.
9
INPUT LEVEL controls
Independent level controls for analog input channels 1 and 2. You can also use these
controls to balance the left and right channels of a stereo source connected to the analog
inputs. Note that the input level automatically changes to accommodate microphone or
line input.
0
MIC 1 & 2
Two 1/4-inch jacks for direct input of microphone analog audio signals. These are
unbalanced inputs with nominal input levels of –60dBm. Plugging a microphone into
either of these jacks automatically switches the channel’s nominal input level from line
(–20dBm) to microphone (–60dBm).
Note that connecting a cable to a MIC jack automatically disables any line input connected
to the corresponding ANALOG IN jack on the near panel.
IMPORTANT:
1. NEVER plug a line input into a MIC jack.
2. Always set the INPUT LEVEL to minimum before inserting or removing a
microphone or line input.
NOTE:
The top LED in each of the bargraphs is the “CLIP” LED. While peak
indicators on analog equipment tend to light up approximately 3 ~ 6dB below
the signal clipping level, CLIP LEDs on digital equipment come on only if
clipping has actually occurred. Since digital-audio signal clipping produces
unpleasant distortion, pops, and clicks, you DO NOT want the CLIP LEDs to
come on.

The CBX-D3 receives MIDI control data from the computer via this connection. To ensure
that control data is not delayed by other MIDI devices, the CBX-D3 should be the first
device connected to your computer. If your computer provides multiple MIDI outputs, you
should dedicate one of these for exclusive use with the CBX-D3.
7
DIGITAL OUT
A RCA (phono) jack that outputs CD/DAT-format digital audio. Channels 1 and 3 are
output as the “L” signal, while 2 and 4 are output as the “R” signal. This jack allows you
to connect directly to the digital input of a DAT or DCC recorder, eliminating the need for
multiple D/A and A/D conversions.

SCSI ID selector
A thumbwheel switch used to set the SCSI ID for the CBX-D3. See “SCSI ID setting”
(page 12) for more information.
9
SCSI connectors
Two 50-pin Amphenol type connectors used to connect the CBX-D3 to the SCSI daisy
chain.
NOTE:
Be sure to connect this to the MIDI IN terminal of your computer prior to
recording or playback.
NOTE:
Be sure to connect the MIDI IN terminal to the MIDI OUT terminal of your
computer prior to recording or playback.
NOTE:
It is well known that the weakest links in a digital audio system are the A/D and
D/A converters. Once converted to digital form, the audio signal becomes
immune to distortions, noises, and other problems generally introduced by
analog equipment. Although the effect of multiple conversions is rather subtle,
it is nevertheless good practice to reduce the number of conversions and
transfer the data in digital form wherever possible.
10 Chapter 5 : Connecting Hard Disk Drives10 Chapter 5 : Connecting Hard Disk Drives10 Chapter 5 : Connecting Hard Disk Drives
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 set up.
What type of hard disk?
If you don’t already have a hard disk or are thinking of buying a larger one, please consult
your Yamaha CBX-D3 dealer for recommendations.
Hard disk size
The following table shows approximate available recording times for various sizes of hard
disk. Available recording times are shown for all of the CBX-D3’s sampling frequencies.
As you can see, time capacity decreases as sampling frequency goes up. This is because
the higher frequencies generate much more digital data, and therefore require much more
space. For details about frequency selection, refer to “Sampling Frequency” on page 16.
Although it is doubtful that you will ever buy a hard disk smaller than 40MB for use with
the CBX-D3, the values below 40MB will be useful for checking the remaining recording
time on a hard disk that already contains some sound files.

Choosing a hard disk
Consider the following disk specifications when shopping for a hard disk for your
CBX-D3 system.
SCSI
For a general introduction to SCSI, see “SCSI” on page 3.
Setting up a SCSI daisy chain involves a little more than just making connections. Each
SCSI device must be assigned an ID number, and the daisy chain must be terminated
correctly. Details are explained in the following three sections, “SCSI cables,” “SCSI ID
setting,” and “SCSI termination.”
When using a SCSI daisy chain, bear the following points in mind.
• Each device must have a unique SCSI ID number.
• The SCSI bus must be correctly terminated.
• Use quality cables and keep the length down.
• Use the wire clips (or screws) on the SCSI connectors to secure the cable
connections.
• All devices connected in the daisy chain must be switched on.
• Never switch off or disconnect a device once the system is running.
Specification Check Notes
Is it compatible with your computer?
It may be advertised as compatible, or your
dealer may recommend it.
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-pin Amphenol?
Macintosh computers are fitted with a 25-pin
D-SUB connector, while most other SCSI devices
use a 50-pin Amphenol connector.
Are the SCSI cables supplied? If not, you will need to purchase these separately.
Can the SCSI ID be set from 0 ~ 7?
(For Macintosh, you only need 0 ~ 6)
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.
Does it have internal or external
termination?
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.
Access time?
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. Access times slower than this will degrade
the performance of the CBX-D3.
Data transfer rate?
Usually measured in megabytes per second
(MB/sec), this indicates how fast data can be
written to and read from the hard disk. The
minimum we recommend is 1MB/sec. A transfer
rate less than this will degrade the performance
of the CBX-D3.
NOTE:
Switch off all your equipment before making any SCSI connections.

SCSI cables
Cable length should be kept low. The total length of the SCSI daisy chain must not exceed
6m (20ft).
SCSI ID setting
The SCSI bus is a parallel type connection, and data on the bus is available to all devices.
However, communication will 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 a unique ID number. SCSI devices usually have a DIP switch or, like the
CBX-D3, a thumbwheel switch that you can use to set the ID. Refer to the instructions
supplied with the device.
The example above shows seven devices (computer and six peripherals) connected in a
SCSI daisy chain. Each device has a different ID number. Note that the last device in the
chain is terminated. In most cases SCSI ID 7 is reserved for use by the computer, and ID
0 for the internal hard disk. Do not use either of these IDs for any other 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.
Some SCSI devices have a built-in terminator, and must therefore be connected at the end
of the daisy chain. The CBX-D3 and many other devices utilize a detachable in-line
terminator, as illustrated below.
NOTE:
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.

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. The system will not recognize
an unformatted hard disk.
Formatting
Most SCSI hard disks are supplied with their own disk-formatting software. Please format
the disk according to directions given in the hard disk’s operating manual.
The formatting program will probably ask you to specify the disk’s SCSI ID number. This
is the ID number that you set using the thumbwheel or DIP switch on the hard disk unit.
You may also be asked to set the interleave value; if so, refer to the hard disk’s operating
manual for the appropriate response. Also check your computer’s manual for additional
information about connection of SCSI disk drives.
File management and backup
Once you have stored sound files to disk, you can copy, delete, or size-check them using
the same commands that you use for your other computer files.
You can also back them up using conventional data compression and backup utilities.
However, due to the relatively large size of sound files, floppy disks are not the most
effective backup media. Removable hard disks and magneto-optical disks are well suited
to this task; commonly available sizes include 88MB, 128MB, and 650MB.
Another backup option is to digitally transfer your sound files to a DAT recorder. You can
then record them back to the CBX-D3 if the need arises.
Computer utilities
There are many computer utilities available for managing files and hard disks. Disk
defragmentation utilities are particularly useful, as described below. File compression
utilities, which increase the apparent disk capacity by compressing your files, are a
different matter. We recommend that you either avoid these or use them with extreme care,
as some of these utilities are incompatible with the CBX-D3 and may effectively destroy
your sound files.
