The input level range is from -62 dBu to +10 dBu. +48V phantom power can be supplied to devices that require it via the input connectors. NOTE The PAD will be switched on or off internally when the gain of the internal head amp is adjusted between +17 dB and +18 dB. Keep in mind that noise may be generated if there is a difference between the Hot and Cold impedance of the external device connected to the INPUT connector when using phantom power. 2 OUTPUT +4 dBu Connectors 1-8 (Ro8-D only) These XLR-3-32 type balanced connectors deliver analog output from the unit's corresponding output channels. Nominal output level is +4 dBu. 3 [+48V] Indicators (Ri8-D only) These indicators light when +48V phantom power is turned ON for the corresponding input channels. 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 flash). 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. Doing so can damage the connected device and/or the unit itself. • 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 78 controls to minimum when turning phantom power ON or OFF. Sudden high level peaks caused by the switching operation can damage equipment as well as the hearing of those present. 4 [PEAK] Indicators (Ri8-D only) These indicators light red when the signal level of the corresponding channel reaches or exceeds -3 dBFS. The PEAK indicators also function as error indicators: the indicators for all channels will flash if an error occurs. 5 [SIG] (Signal) Indicators These indicators light green when the signal applied to the corresponding channel reaches or exceeds -34 dBFS. The SIG indicators also function as error indicators: the indicators for all channels will flash if an error occurs. 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. Use the rotary switch while the power to the unit is turned OFF. 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
