Important Information
Please read before operating the DA824
Warnings
•Do not subject the DA824 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 DA824 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 DA824. 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 DA824, 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 DA824 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 DA824, turn it off immediately. Remove the power cord from the
AC outlet and consult your dealer for repair. Using the DA824 in this condition is a fire
and electrical shock hazard.
•Do not place small objects on top of the DA824. Metal objects falling inside the DA824
is a fire and electrical shock hazard.
•If a foreign object or water gets inside the DA824, turn it off immediately. Remove the
power cord from the AC outlet and consult your dealer for repair. Using the DA824 in
this condition is a potential fire and electrical shock hazard.
• Should the DA824 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 DA824’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 DA824. This is a potential fire and electrical shock hazard.
•Do not block the DA824 ventilation slots. Blocking the ventilation slots is a potential
fire hazard.
•Do not place a container with liquid or small metal objects on top of this unit. Liquid
or metal objects inside this unit are a fire and electrical shock hazard.

•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 accessible. 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, electricity 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.
