NOTE: When using digital connections, you should also make the analog audio input con- nections described previously. The analog connection is necessary to record to an ana- log recorder in some circumstances or for ZONE 2 operation
Digital Outputs 
The RSP-1098 has four digital outputs (two coaxial and two optical) to send the digital signal from any of the digital inputs to a digi- tal recorder or outboard digital processor. When a digital input source signal is selected for listening, that signal is automatically sent to both digital outputs for recording.
NOTE: Only digital signals from source com- ponents are available at these outputs. Ana- log signals cannot be converted and are not available at the digital outputs.

12V TRIGGER Connections 
Many Rotel amplifiers offer the option of turning them on and off using a 12 volt trigger. These four connections provide this 12 volt trigger signal from the RSP-1098. When the RSP-1098 is activated, a 12 volt DC signal is sent to the amplifiers to turn them on. When the RSP-1098 is put in STANDBY mode, the trigger signal is interrupted and the amplifiers turn off.
To use the remote turn on feature, connect one of the RSP-1098’s 12V TRIG OUT jacks to the 12 volt trigger input of a Rotel amplifier, us- ing a cable with mono 3.5 mm mini-plugs on both ends. The +12 V DC signal appears at the “tip” connector.
NOTE: The 12V Trigger outputs can be config- ured to turn on only when specific input sources are activated. See the Input Setup and Zone 2 Setup menus in the Setup section of this manual for details.
NOTE: The IR signals from the EXT REMOTE IN jack (as well as those from the ZONE 2/ ZONE 3 REMOTE IN jacks) can be relayed to source components using external IR emit- ters or hard-wired connections from the IR OUT jacks. See the following section for ad- ditional information.
IR OUT Jacks 
The IR OUT 1 & 2 jacks send IR signals re- ceived at the ZONE REM IN jacks or the EXT REM IN jack to an infrared blaster or emitter placed in front of a source component’s IR sensor. In addition, the IR OUT can be hard- wired to Rotel CD players, DVD players, or tuners with a compatible connector.
These outputs are used to allow IR signals from Zone 2 to be sent to the source components, or to pass along IR signals from a remote in the main room when the sensors on the source components are blocked by installation in a

AC Input 
Your RSP-1098 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 115 volts/60Hz AC or CE: 230 volts /50 Hz AC ). The AC line configuration is noted on a decal on the back of your unit.
Plug the supplied cord into the AC INPUT receptacle on the back of the unit.
NOTE: Memorized settings and video labels are preserved indefinitely, even if the RSP-1098 is disconnected from AC power.
Master Power Switch 
The large rocker switch on the rear panel is a master power switch. When it is in the OFF position, power to the unit is completely off. When it is in the ON position, the front panel STANDBY and remote control ON/OFF but- tons can be used to active the unit or put it standby mode.
NOTE: After all connections are completed, the rear panel master power switch should be put in the ON position and usually left in that position.
REM IN Jacks 
Three 3.5 mm mini-jacks (labeled REM IN, ZONE 2, and ZONE 3) receive command codes from an industry-standard infrared re- ceivers (Xantech, etc.), used when the IR sig- nals from a hand held remote control cannot reach the front panel IR sensor.
EXT: The EXT jack is used with an outboard IR receiver to duplicate the front panel IR sen- sor. This feature is useful when the unit is in- stalled in a cabinet and the front panel sen- sor is blocked or when IR signals need to be relayed to other components.
ZONE 2 and ZONE 3: These two jacks are used with IR repeater systems to receiver sig- nals from IR control systems in remote loca- tions. For example, remote control signals sent to the ZONE 2 REM IN control the ZONE 2 features of the RSP-1098 and can be relayed to other components. Remote control signals sent to the ZONE 3 REM IN can be used to select the RECORDING source (the signal available at the TAPE OUT connections).
Consult your authorized Rotel dealer for in- formation on external receivers and the proper wiring of a 3.5 mm mini-plugs to fit the REM IN jacks.

See your authorized Rotel dealer for information on IR emitters and repeater systems.
Computer I/O 
The RSP-1098 can be operated from a com- puter with audio system control software from third-party developers. This control is accom- plished by sending operating codes from the computer via a hard-wired RS-232 serial con- nection. In addition, the RSP-1098 can be up- dated using special software from Rotel.
The COMPUTER I/O input provides the nec- essary network connections on the rear panel. It accepts standard RJ-45 8-pin modular plugs, such as those commonly used in 10-BaseT UTP Ethernet cabling.
For additional information on the connections, cabling, software, and operating codes for com- puter control or updating of the RSP-1098, con- tact your authorized Rotel dealer.
