3-3. Precautions for rack mounting This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. If you mount this unit along with other MMP1 unit(s) or other device(s) in an EIA standard equipment rack, temperatures inside the rack may rise, possibly resulting in impaired performance. When rack mounting the unit, always observe the following requirements to avoid heat buildup: • When mounting the unit in a rack with devices such as power amplifiers that generate a significant amount of heat, leave 1U space or more between the MMP1 and other equipment. Also, either leave the open spaces uncovered or install appropriate ventilating panels to minimize the possibility of heat buildup. • 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 cannot be left open, install a commercially-available fan or similar ventilating option to ensure sufficient airflow. If you have 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. 3-4. Power supply 3-4-1. Connecting the AC power cord 1. Make sure that the 1 [MAIN] power switch and the 1 [BACKUP] power switch are in the standby position (/). 2. Connect the supplied power cord to the AC power input socket of the unit. 3. Connect the other end of power cord to an AC outlet. NOTE • To disconnect the power cord, remove the cable in the order of steps 1  3  2 in the procedure described above. • To disconnect the power cord, remove it while holding down the latch on the plug. WARNING Use only the supplied AC power cord. Using other cables may lead to overheating or electric shock. CAUTION Be sure to set to standby the power to the unit before connecting or disconnecting the power cord. NOTICE Even when the power switch is in the standby position (/), a small amount of current is flowing through the unit. If you plan not to use the unit for a long period of time, be sure to remove the power cord from the AC outlet. 3. Location and Connections 3-4-2. Turning the power on and set to standby When you turn on the power to the unit, be sure to turn on the power to the power amplifiers and/or powered speakers last to avoid speaker damage. Before you set to standby the power of the unit, first turn off the power to the power amplifiers and/or powered speakers. 3-5. About Dante Dante is a network audio protocol developed by Audinate. It is designed to deliver multi-channel audio signals at various sampling and bit rates, as well as device control signals over a Giga-bit Ethernet (GbE) network. Visit the Audinate website for more details on Dante: https://www.audinate.com/ More information on Dante is also posted on the Yamaha Pro Audio website: http://www.yamahaproaudio.com/ 3-6. Notes regarding the use of network switches Do not use the EEE functionality (*) of network switches on a Dante network. Although mutual power consumption settings between switches that support the EEE functionality are adjusted automatically, there are some switches for which such mutual settings are not adjusted correctly. This may cause EEE to be enabled in Dante networks when it is not appropriate, resulting in poor synchronization performance and occasional dropouts. Therefore we strongly recommend the following. • If you use managed switches, please disable the EEE functionality. Do not use switches that prevent EEE functionality from being disabled. • When using unmanaged switches, do not use switches that support EEE functionality. EEE functionality cannot be disabled for such switches. * EEE (Energy Efficient Ethernet) is a technology that reduces switch power consumption during periods of low network traffic. It is also referred to as Green Ethernet and IEEE802.3az. 3-7. Dante network settings and audio routing With the Dante network, you can route the audio input and output of multiple Dante devices in any way you like. This requires you to set which channel signals are sent to which inputs. Use Dante Controller to configure the audio routing of the Dante network. You can download Dante Controller from the following website: https://www.audinate.com/products/software/dantecontroller?lang=en Refer to the Dante Controller owner's manual (available from the same website) for details about Dante Controller.
