Be sure to connect to an appropriate outlet with a protective grounding connection.
Improper grounding can result in electrical shock.
Cautions
If this device is to be mounted in an EIA-standard rack, leave the back of the rack open
and make sure that it is at least 10 cm away from walls or surfaces. Also, if this device is
to be mounted with devices that tend to generate heat, such as power amplifiers, be sure
to keep an adequate gap between this device and the heat-generating devices or install
ventilation panels to prevent high temperatures from developing inside this device.
Under these conditions these devices can be rackmounted. Inadequate ventilation can
result in overheating, possibly causing damage to the device(s), or even fire.
•
•
•
•
•
Use the DA824 in an environment where the temperature is between 10˚C and 35˚C
(50˚F and 95˚F).
Turn off audio devices when connecting them to the DA824, and use only the cables
specified in the relevant owner’s manuals.
If you plan not to use the DA824 for a long period of time, remove the power cord from
the AC outlet. Leaving the DA824 connected is a potential fire hazard.
Do not use benzene, thinner, cleaning detergent, or a chemical cloth to clean the
DA824. Use only a soft, dry cloth.
If the DA824 is stored in a cold place (e.g., overnight in a car), and then moved to a
warmer environment, or the temperature rises sharply, condensation may form inside
the DA824, which may affect performance. In such cases, the DA824 should be allowed
to acclimatize for about one hour before use.
•
•
When the wordclock source is changed, the DA824’s analog outputs may produce
noise, especially if an MY8-AT I/O card is installed, so turn down your power amps
beforehand. Likewise, when changing the wordclock source on the wordclock master
device (e.g., AD824 or DME32), turn down your power amps beforehand, or turn off
the DA824.
When setting up the product, make sure that the AC outlet you are using is easily acces-
sible.If some trouble or malfunction occurs,immediately turn off the power switch and
disconnect the plug from the outlet. Even when the power switch is turned off, electric-
ity is still flowing to the product at the minimum level. When you are not using the
product for a long time, make sure to unplug the power cord from the wall AC outlet.
Interference
The DA824 uses high-frequency digital circuits that may cause interference on radio
and television equipment located nearby. If interference is a problem, relocate the
affected equipment.

1 Introduction
Welcome
Thank you for choosing the Yamaha DA824 DA Converter.
The DA824 is a high-performance 8-channel digital-to-analog converter, with 24-bit
linear digital-to-analog converters and 128-times oversampling providing a typical
dynamic range of 110 dB. Optional mini YGDAI (Yamaha General Digital Audio Inter-
face) cards offer a variety of digital input interfaces, with support for all the popular dig-
ital audio interconnect formats, including AES/EBU, ADAT, and Tascam TDIF-1.
Installation
The DA824 can be used freestanding on a stable surface, somewhere that complies with
the important information at the beginning of this manual, or mounted in a rack.
When mounting the DA824 in a rack, leave adequate ventilation space around the
DA824 (at least 10 cm of free space behind). If the DA824 is mounted in a portable rack
case, keep the rear of the case open when using the DA824, so as not to obstruct the flow
of air from the air vents. Do not mount the DA824 next to equipment that produces a
lot of heat, such as a power amplifier.
Setting the Maximum Output Level
Inside the DA824 are eight output-level switches for presetting the maximum output
level of each analog output. Maximum output levels settings are: +24 dB, +18 dB,
+15 dB, and +4 dBV. See you Yamaha dealer for more information.
Connecting the Power Cord
Warning: Turn off all equipment before making any connections.
Connect the power-cord plug to a suitable AC wall outlet, one that conforms to the
power supply requirements stated on the DA824 rear panel.
Turning On the Power
To prevent audible thumps and clicks, turn on your audio equipment in
the following order (reverse this order when turning off your equip-
ment)—sound sources, mixer or recorder (e.g., 02R, DME32, D24, etc.),
DA824, power amplifiers.

Chapter 5—Wordclocks
5 Wordclocks
About Wordclocks
For correct operation and digital-to-analog processing, it is essential that the DA824 is
wordclock locked to the digital audio device transmitting the digital audio signals. Nor-
mally, the DA824 locks to a wordclock signal derived from the SLOT digital audio
inputs, but when a usable wordclock signal is present at the WORD CLOCK IN con-
nector, this is used instead.
The LOCK indicator lights up when the DA824 is locked to the wordclock source and
synchronized to the digital audio signal. It flashes if the DA824 is not synchronized to
the digital audio signal.
Note: When the wordclock source is changed, the DA824’s analog outputs may produce
noise, especially if an MY8-AT I/O card is installed, so turn down your power amps before-
hand. Likewise, when changing the wordclock source on the wordclock master device (e.g.,
AD824 or DME32), turn down your power amps beforehand, or turn off the DA824.
Wordclock Hookup Examples

Wordclock Termination
For correct and reliable operation, wordclock signals distributed via BNC cables must
be terminated correctly. Termination is typically applied at the last device, although it
depends on the distribution method being used. The DA824’s WORD CLOCK 75Ω
ON/OFF switch allows the DA824 to be connected in a variety of ways. The following
examples show three ways in which wordclock signals can be distributed and how ter-
mination should be applied in each case.
Wordclock Distribution Box
In this example, a dedicated wordclock distribution box is used to supply a wordclock
signal to each device individually. Termination is applied at each device.
