DA824—Owner’s Manual
• 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.
