IMPORTANT NOTICE: DO NOT MODIFY THIS UNIT!This product, when installed as indicated in the instructions contained in this manual, meets FCC requirements. Modifications not expressly approved by Yamaha may void your authority, granted by the FCC, to use the product. [. . . ] Liquid or metal objects inside this unit are a fire and electrical shock hazard. DA824--Owner's Manual ii · 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. · 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. DA824 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 DA824. Yamaha cannot be held responsible for any loss of data or data damage due to improper use or operation of the DA824.

Normally, 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 connector, 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. [. . . ]
