[. . . ] Compliance with FCC regulations does not guarantee that interference will not occur in all installations. If this product is found to be the source of interference, which can be determined by turning the unit "OFF" and "ON", please try to eliminate the problem by using one of the following measures: Relocate either this product or the device that is being affected by the interference. Utilize power outlets that are on different branch (circuit breaker or fuse) circuits or install AC line filter/s. In the case of radio or TV interference, relocate/reorient the antenna. [. . . ] Using the unit with a damaged power cord is a fire and electrical shock hazard. · Do not remove the unit's cover. If you think internal inspection, maintenance, or repair is necessary, contact your dealer. Doing so is a fire and electrical shock hazard. · When rack-mounting the unit, 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. · For normal ventilation during use, remove the rear of the rack or open a ventilation hole. · If the airflow is not adequate, the unit will heat up inside and may cause a fire. · This unit has ventilation holes at the top, bottom, and rear to prevent the internal temperature rising too high. Blocked ventilation holes are a fire hazard. · Hold the power cord plug when disconnecting it from an AC outlet. A damaged power cord 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. · The digital circuits of this unit may induce a slight noise into nearby radios and TVs. If noise occurs, relocate the affected equipment. · XLR-type connectors are wired as follows: pin 1: ground, pin 2: hot (+), and pin 3: cold (­). Rack Mounting Caution If the unit is rack mounted and transported regularly, for example, when on a tour, we recommend that the rear of the unit be supported by fitting a pair metal brackets, one each side. The following drawing provides the information necessary to make such brackets. Note that only one bracket is shown here and the bracket for the other side must be bent in the opposite direction. 2-R2 2-R2 (82. 1) 76. 2 31. 75 R5 3. 1 20. 5 200 0 5. 9 4- ø 6. 5 0 7. 5 36. 5 14. 5 t = 1. 6 134 0 8 12 R2 3 86. 5 44. 45 Thank you for choosing the AI8 analog input box, or the AI8-ML8/AI8-AD8/AI8-ML4AD4 analog input unit, specifically designed for the Yamaha PM1D digital audio mixing system. The AI8 inputs signals to the DSP unit DSP1D/DSP1D-EX engine (controlled via the CS1D control surface). Up to ten AI8s can be connected to each DSP1D/DSP1D-EX. Be sure to ask an authorized Yamaha service engineer to install the card and set up the unit. Never perform installation and setup by yourself. [. . . ] Use a BNC cable with an impedance of 75 for connection. The WORD CLOCK ON/OFF switch is used to terminate the word clock connection. Basically, if the AI8 is the last device of the word clock chain, or if nothing is connected to the WORD CLOCK IN/OUT jacks, set this switch to ON. G WORD CLOCK OUT jack ". . " " " means that the control signal from the CS1D has changed the setting to "A. " " " means that the control signal from the CS1D has changed the setting to "B. " During this time period, you can connect or disconnect the cable from the unselected output connector. [. . . ]
