The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The above warning is located on the top of the unit. IMPORTANT SAFETY INSTRUCTIONS 1 2 3 4 5 6 7 8 Read these instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] Phantom power supply switching can be carried out from a compatible digital mixing console or computer application. No phantom power will be supplied, however, if the [+48V MASTER] switch is OFF, even if phantom power to individual channels is turned ON (the +48V indicators will still light). The +48V indicators also function as error indicators: the indicators for all channels will flash if an error occurs. CAUTION: • Make sure that phantom power is turned OFF unless it is needed. • When turning phantom power ON, make sure that no equipment other than phantom-powered devices such as condenser microphones are connected to the corresponding [INPUT] connectors. Applying phantom power to a device that does not require phantom power can damage the connected device. • Do not connect or disconnect a device to an INPUT while phantom power is applied. • To prevent possible damage to speakers, make sure that power amplifiers and/or powered speakers are turned OFF when switching phantom power ON or OFF. We also recommend setting all digital mixing console output 6 [UNIT ID] Rotary Switch This rotary switch enables you to set an ID number so that connected devices will recognize the Ri8-D/Ro8-D. The UNIT ID must be a unique number in the network so that the Ri8-D/Ro8-D will be able to transmit and receive audio signals over a Dante network, or be controlled from a connected digital mixing console. Otherwise, the ID setting will not be effective. 7 [SYSTEM] Indicators These indicators show the Ri8-D/Ro8-D’s operating status. If the green indicator lights steadily and the red indicator turns off, the unit is operating normally. When power to the unit is turned ON, if the green indicator turns off, or if the red indicator lights or flashes, the unit is not functioning properly. In this case, refer to the “Messages” section (see page 18). 10 Owner’s Manual 1 1 0 A B 1 2 3 4 5 6 7 8 8 Front Panel 8 [SYNC] Indicators These indicators show the operating status of the Ri8-D/Ro8-D’s internal Dante network capability. If the green indicator lights, the unit is operating as a word clock slave and synching to the word clock. If the green indicator flashes, the unit is operating as the word clock master. If the power to the unit is turned on but the green indicator is turned off, the unit is not functioning properly. In this case, refer to the “Messages” section (see page 18). If the orange indicator lights or flashes, refer to the “Messages” section. With the [REDUNDANT] setting, the [PRIMARY] connector will be used for primary connections, and the [SECONDARY] connector will be used for secondary (backup) connections. If the unit is unable to transmit signals through the [PRIMARY] connector for some reason (e. g. , due to damage or accidental removal of the cable, or a failed network switch), the [SECONDARY] connector will automatically take over communications and functions on the redundant network. Refer to “About Redundant Networks” in the “About Connections” section (see page 14) for more information on redundant networks. Switch Setting DAISY CHAIN Description The [SECONDARY] connector is used for a daisy chain connection. It can be connected in a daisy chain by connecting to [PRIMARY] terminal of the next device. It will function as backup connection, independent of the network to which the [PRIMARY] connector is connected. 9 DIP Switches These switches enable you to specify the settings related to the startup operation of the unit.
