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.
