Important Information
Please read the following before using the AD824
Warnings
• Do not subject the AD824 to extreme temperatures, humidity, direct sunlight, or dust,
which could be a potential fire or electrical shock hazard.
• Do not allow water to enter the AD824 or allow it to become wet. Fire or electrical shock
may result.
• Connect the power cord only to an AC outlet of the type stated in this Owner’s Manual
or as marked on the AD824. Failure to do so is a fire and electrical shock hazard.
• Hold the power-cord plug when disconnecting from an AC outlet. Never pull the cord.
A power cord damaged through pulling is a potential fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing so is a potential electrical shock
hazard.
• Do not place heavy objects, including the AD824, on top of the power cord. A damaged
power cord is a fire and electrical shock hazard. In particular, be careful not to place
heavy objects on a power cord covered by a carpet.
• Do not scratch, bend, twist, pull, or heat the power cord. A damaged power cord is a
fire and electrical shock hazard.
• If the power cord is damaged (e.g., cut or a bare wire is exposed), ask your dealer for a
replacement. Using the AD824 with a damaged power cord is a fire and electrical shock
hazard.
• Do not plug several devices into the same AC outlet. This may overload the AC outlet,
and could be a fire or electrical shock hazard. It may also affect the performance of some
equipment.
• If you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or
liquid gets inside the AD824, turn it off immediately. Remove the power cord from the
AC outlet and consult your dealer for repair. Using the AD824 in this condition is a fire
and electrical shock hazard.
• Do not place small objects on top of the AD824. Metal objects falling inside the AD824
is a fire and electrical shock hazard.
• If a foreign object or water gets inside the AD824, turn it off immediately. Remove the
power cord from the AC outlet and consult your dealer for repair. Using the AD824 in
this condition is a potential fire and electrical shock hazard.
• Should the AD824 be dropped or the cabinet be damaged, turn off the power, remove
the power plug from the AC outlet, and contact your dealer. If you continue using the
unit without heeding this instruction, fire or electrical shock may result.
• Do not remove the AD824’s cover. You could receive an electrical shock. If you think
internal inspection, maintenance, or repair is necessary, contact your dealer.
• Do not attempt to modify the AD824. This is a potential fire and electrical shock hazard.
• Do not block the AD824 ventilation slots. Blocking the ventilation slots is a potential
fire hazard.
AD824—Owner’s Manual
ii
Cautions
• Allow enough free space around the unit for normal ventilation. This should be: 10 cm
at the sides, 15 cm behind, and 30 cm above. These distances should also be adopted
when rack-mounting the AD824. For normal ventilation during use, remove the rear
of the rack or open a ventilation hole. If the airflow is not adequate, the AD824 will heat
up inside and may cause a fire.
• Use the AD824 in an environment with a temperature of between 10˚C and 35˚C (50˚F
and 95˚F).
• Turn off all equipment before connecting it to the AD824, and use only the cables specified in the relevant owner’s manuals.
• If you plan not to use the AD824 for a long period of time, remove the power cord from
the AC outlet. Leaving the AD824 connected is a potential fire hazard.
• Do not use benzene, thinner, cleaning detergent, or a chemical cloth to clean the
AD824. Use only a soft, dry cloth.
• If the AD824 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 AD824, which may affect performance. In such cases, the AD824 should be allowed
to acclimatize for about one hour before use.
• When the wordclock source is changed on the wordclock master device (e.g., this
AD824, a DME32 or 02R), noise may occur from the outputs of the wordclock slave
devices, especially a AD824 with an MY8-AT I/O card installed, so turn down your
power amps beforehand, otherwise any connected speakers may be damaged.
• If the error code “E1” or “E3” appears on the GAIN display when the AD824 is turned
on, see your dealer about changing the internal backup battery. Although the AD824
will work even when the battery voltage is low, it may not remember the current settings
next time it’s turned on.
Interference
The AD824 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.
AD824 Exclusion of Certain Responsibility
Manufacturer, importer, or dealer shall not be liable for any incidental damages including personal injury or any other damage caused by improper use or operation of the
AD824.

1 Introduction
Welcome
Thank you for choosing the Yamaha AD824 AD Converter. The AD824 is a high-performance 8-channel analog-to-digital converter, with 24-bit linear analog-to-digital
converters and 128-times oversampling, providing a typical dynamic range of 110 dB.
Optional mini YGDAI (Yamaha General Digital Audio Interface) cards offer a variety
of digital output interfaces, with support for all the popular digital audio interconnect
formats, including AES/EBU, ADAT, and Tascam TDIF-1.
Analog inputs feature electronically balanced XLRs, high-quality mic preamps, independently switchable 48-volt phantom powering, and rotary gain adjustment. Inputs
can be used with either microphones or line-level sources. Analog outboard equipment
can be patched into each channel by using the electronically-balanced analog insert
points on two 1/4" TRS phone jacks.
Remote control from a Yamaha DME32, personal computer, or other device is possible
using an exclusive control protocol.
Introduction
1
Installation
The AD824 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 AD824 in a rack, leave adequate ventilation space around the
AD824 (at least 10 cm of free space behind). If the AD824 is mounted in a portable rack
case, keep the rear of the case open when using the AD824 so as not to obstruct the flow
of air from the air vents. Do not mount the AD824 next to equipment that produces a
lot of heat, such as a power amplifier.
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 AD824 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)—sound
sources, AD824, mixer or recorder (e.g., 02R, DME32, D24, etc.), power
amplifiers.
