1 Introduction

Welcome to the CBX-D3

Thank you for purchasing a CBX-D3 Digital Recording Processor. Connecting the
CBX-D3 to a controlling computer with supporting software and a SCSI hard disk will
provide up to four channels of CD quality audio recording, processing, and playback.

CBX-D3 features

• Four-channel system: 2-channel simultaneous recording, 4-channel playback

• A/D conversion: 16-bit linear ∆ Σ modulation

• D/A conversion: 18-bit with oversampling digital filter

• Sampling frequencies: 48kHz, 44.1kHz, 32kHz, 22.05kHz

• Two analog inputs (two LINE jacks, two MIC jacks); four analog outputs. The analog
input level automatically switches to accommodate line or microphone input.

• One CD/DAT digital output

• Available recording time is limited only by hard disk capacity.
You can increase the recording time by installing larger disks or increasing the number
of disks.

• All audio data processing is carried out within the CBX-D3, so much less is demanded
of the computer, eliminating data bottlenecks and slow screen redraws.

• The system can be easily upgraded by loading the appropriate files. No ROM change
is required.

Unpacking

The CBX-D3 package should contain the following items.

1 CBX-D3 Serial No:
1 PA-5B AC Adaptor (or recommended equivalent)
2 1U rack mounting brackets (attached to the CBX-D3)
1 Owner’s Manual
1 User Registration Card

Retain the packing materials for future use.

Installation

The CBX-D3 comes equipped with mounting brackets at both sides, allowing easy
installation on any standard 19" electronic equipment rack. (The unit requires 1U of rack
space.)

If you need to remove the mounting brackets, simply remove the three screws holding each
bracket in place. Be sure to reuse the same screws when reattaching the brackets; use of a
different screw size can cause internal damage.

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.

NOTE: To avoid system crash and data loss, NEVER switch off or disconnect any of

the SCSI devices while the CBX-D3 system is running.

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.

Downloader” program, available on request from your Yamaha CBX-D3 dealer.

NOTE: Consult your Yamaha CBX-D3 dealer for information about the latest

CBX-D3 applications.

2 CBX-D3 Terminology

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.

CBX-D3 Terminology3CBX-D3 Terminology3CBX-D3 Terminology 3

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.

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).

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.

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 that connecting a cable to the MIC jack on the front panel automatically disables the
corresponding ANALOG IN jack. If cables are connected to both MIC and ANALOG IN,
only the MIC (nominal –60dBm) signals will be received.

NOTE:

Four 1/4-inch phone jacks that output audio data in analog form. These are unbalanced

If you connect a line to OUT1 only, the OUT1 jack will output audio signals for all four
channels. If you connect to OUT1 and OUT2 only, then OUT1 will output channels 1 and
3, while OUT2 will output channels 2 and 4.
