Recorder Connections 
The Tape 1 and Tape 2 inputs and outputs can be connected to any record/playback device that accepts standard line level analog input and output signals. Typically that will be a con- ventional tape recorder.
When connecting a recorder to the RC-1090, remember that the outputs of the recorder must be connected to the tape inputs of the RC-1090. Similarly the tape outputs of the RC-1090 must be connected to the inputs of the recorder. As with other sources be sure to connect the Left and Right channels of each device to the proper channels on the associated components. Use high quality connecting cables to prevent loss of sound quality.
Output Connections
NOTE: The RC-1090 has both RCA and XLR type output connectors. The two sets of outputs must not be used at the same time.
Balanced Output Switch 
When the RCA outputs are used the Balanced Output switch must be set to the Off position. Set the switch in the On position when using the XLR Balanced outputs.
RCA Outputs 
[See Figure 4 for RCA output connec- tion illustration.]
Most power amplifiers have RCA-type input connectors. With such amplifiers the Balanced
Outputs switch 
must be set to the Off position. Then connect a set of cables between the outputs of the RC-1090 and the inputs of the amplifier. As always, use high quality cables and be sure to connect the Left and Right channel outputs of the RC-1090 to the cor- rect channels of the amplifier.
NOTE: There are two sets of RCA outputs on the RC-1090. The second set of outputs may be used in custom system configura- tions to drive a second power amplifier or to supply a signal to a special signal pro- cessor.
Balanced XLR Outputs 
[See Figure 5 for Balanced XLR out- put connection illustration.]
The XLR type outputs of the RC-1090 are “bal- anced” outputs. These provide the advantage of allowing the power amplifier to be placed a great distance from the RC-1090 without caus- ing loss of sound quality or picking up noise over the long cable run. Of course the associ- ated power amplifier must have balanced XLR- type inputs in order to use this feature.
When using the XLR outputs the Balanced Output switch 
must be set to the On po- sition. Then simply connect a cable with XLR connectors to the RC-1090 outputs and power amplifier inputs. Be sure to connect the Left and Right channel outputs of the RC-1090 to the correct channels of the amplifier. If you have questions about the proper type of cable to use, consult your authorized Rotel dealer.
12 Volt Trigger Outlet 
Some audio components can be turned on automatically when they receive a 12V turn on “signal”. The 12V Trigger Outputs of RC-1090 provides the required signal. Con- nect the compatible components to the RC-1090 with a conventional 1/8” miniplug cable. When the RC-1090 is in Standby mode, the trigger signal is interupted, so the com- ponents controlled by it are turned off.
IR Inputs and Outputs
External Remote Input 
This 3.5 mm mini-jack (labeled EXT REM IN) receives command codes from an industry- standard infrared receivers (Xantech, etc.) located in the main listening room. This fea- ture is useful when the unit is installed in a cabinet and the front-panel sensor is blocked. Consult your authorized Rotel dealer for in- formation on external receivers and the proper wiring of a jack to fit the mini-jack receptacle.
NOTE: The IR signals from the EXTERNAL REMOTE IN jack can be relayed to source components using external IR emitters or hardwired connections from the IR OUT jacks.
IR Output 
The IR OUT 1 & 2 jacks send IR signals re- ceived at the EXTERNAL REM IN jack to an infrared emitter placed in front of a source component or to Rotel CD players, cassette decks, or tuners with a compatible rear panel IR connector.
This output is used to allow IR signals to pass along IR signals from a remote control when the sensors on the source components are blocked by installation in a cabinet.
See your authorized Rotel dealer for informa- tion on IR repeater systems.
NOTE: The EXT REM IN jack located next to the these jacks is for use with an external IR sensor duplicating the front panel IR sen- sor and located in the primary zone.
Computer I/O Connector 
The RC-1090 can be operated from a per- sonal computer running audio system control software from third-party developers. This con- trol is accomplished by sending the operat- ing codes normally sent by the RR-969 remote control over a hard-wired network connec- tion from the computer.
The COMPUTER I/O input provides the nec- essary connection on the back panel. It ac- cepts standard RJ-45 8-pin modular plugs, such as those commonly used in 10-BaseT UTP Ethernet cabling.
