NOTE: This device does not have a power switch. B Mode switch Use this mode switch to update the firmware in the future. Do not press this switch if not necessary. C Ground screw To ensure safe operation, be sure to ground the NAI48ES securely. The included power cord has a three-prong plug that will ground the unit when plugged into an appropriately grounded three-prong type AC mains outlet. If the AC outlet is not grounded, be sure to ground the unit by using this ground screw. D [AC IN] connector Connect the included power cord here. First, connect the power cord to the NAI48-ES, then insert the power cord plug into an AC outlet. CAUTION Be sure to use the included power cord. Use of other cords may result in malfunction, overheating, or fire. E [EXT DC INPUT] connector This is an XLR-4-32-type connector for supplying external power (+12V) to back up the NAI48-ES internal power supply. For details, refer to page 24. F [HA REMOTE] connector This is a D-sub 9-pin connector for remotely controlling a Yamaha AD8HR or AD824 AD converter with remote microphone preamp. NOTE: When a computer or the Yamaha PM5D controls an AD8HR or AD824 remotely, the ID number will be automatically assigned in the order in which you connect the AD8HR/ AD824 to the [HA REMOTE] connector. Also, when you connect the AD8HR or the AD824 to multiple NAI48-ES units, you need to assign each of the AD8HR/AD824 units a unique ID number so that there are no duplicates. You can change these ID numbers using AuviTran's AVS-ESMonitor. 2 1 5 4 OUT TX RX TX RX IN OUT IN 8 9J G [WORD CLOCK IN] [WORD CLOCK OUT] connectors These are BNC connectors that receive and transmit word clock signals from and to an external device. The input connector is terminated at 75Ω. NOTE: Either "WORD CLOCK IN", "EtherSound", or "AES/EBU" can be selected as the word clock master source. Use AuviTran's AVS-ESMonitor to change and set the source. H [AES/EBU] 1-6 connectors These are D-sub 25-pin connectors that input and output digital audio signals in the AES/EBU format. In Double Speed mode (88.2 / 96kHz), only [AES/EBU] 1-4 connectors are allowed to input and output digital audio signals. This device does not support Double Channel mode. I [EtherSound IN][EtherSound OUT] connectors These are RJ-45 connectors that connect to other EtherSound devices and a computer using an Ethernet CAT5 cable. See pages 21-23 for system examples. NOTE: • Use a CAT5 STP (Shielded Twisted Pair) cable to prevent electromagnetic interference. • For more details on the EtherSound specifications and the length of available cables, refer to the following website. http://www.ethersound.com/technology/compatibility.php J IN/OUT[TX][RX] indicators Each corresponding indicator blinks when [EtherSound IN]/[EtherSound OUT] connectors transmit or receive signals. When the [Identify] button for the NAI48-ES is selected from AVS-ESMonitor, all four of these indicators blink and will continue blinking until selected a second time. AVS-ESMonitor AVS-ESMonitor is AuviTrans' application software for monitoring and controlling the EtherSound system. Using this application software, you can make detailed EtherSound settings such as the routing.
