Introduction Precautions for Rack Mounting This unit will operate stably in an environmental temperature of 0-40˚C. If you install this device together with multiple units of the same device or other devices in an EIA standard rack, the heat produced by the various devices may raise the ambient temperature inside the rack, resulting in inefficient performance. To ensure that the heat produced by this device can be dissipated appropriately, please ensure the following conditions when rackmounting it. • If multiple units are mounted in the same rack, leave a 1U rack space between every two units. Also either leave the open spaces uncovered or install appropriate ventilating panels to minimize the possibility of heat buildup. • When mounting this device together with other heat-producing equipment such as power amplifiers, leave 1U or more space between it and other devices. Install a ventilation panel in this vacant space or leave it open to ensure adequate cooling. • To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters from walls or other surfaces. If the rear of the rack can't be left open, install a commercially available fan or similar ventilating option to secure sufficient airflow. If you've installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack and/or fan unit manual for details. Before Operation ■ Connecting the AC Power Cable CAUTION • Before connecting the power cable, make sure that the power switches of all devices are turned OFF. First connect the supplied power cable to the [AC IN] socket on the rear panel of the IMX644, then connect the AC plug to an appropriate AC power outlet (make sure the local supply voltage matches the rated AC voltage of the unit). ■ Powering ON or OFF CAUTION • To prevent loud noise bursts from the speakers when powering up the system, turn devices ON in the following order: audio sources (microphones, CD players, etc.), IMX644, and finally power amplifiers. Reverse this order when turning the system off. 1 Press the [ON] end of the [POWER] switch to turn the unit ON. 2 Press the [OFF] end of the [POWER] switch to turn the unit OFF. CAUTION • Rapidly turning the unit ON and OFF in succession can cause it to malfunction. After turning the unit OFF, wait for more than 6 seconds before turning it ON again.
