MULTI Inputs 
These RCA inputs accept seven channels of analog signals from a 5.1 or 6.1 channel pro- cessor or source component. When selected with the front-panel MULTI INPUT button or re- mote EXT IN button, this input overrides any other audio input signal.
Use audio cables to connect the outputs of the source component to the RCA jacks labeled MULTI INPUT, making sure that you observe proper channel consistency, i.e. connect the right front channel to the R FRONT input, etc. Depending on your system configuration, you will make six connections (FRONT LEFT &
RIGHT/SURROUND LEFT & RIGHT/CENTER/ SUBWOOFER) or seven connections (FRONT LEFT & RIGHT/SURROUND LEFT & RIGHT/ CENTER/CENTER BACK/SUBWOOFER).
Video Source Outputs
See Figure 4.
Three of the available video sources (VIDEO 1, 2 and 3) feature outputs that allow you to send a signal to a VCR or other source com- ponent for recording. The recording signal avail- able at all of these outputs is selected globally using the REC button on the front-panel or the ZONE button on the remote and is indepen- dent of the source selected for listening.
NOTE: Recording signals are available at all source outputs, including the source selected for recording. As a general rule, you should not attempt to record to the component whose signal has been selected for recording.
The record outputs for VIDEO 1, 2, and 3 in- clude a pair of RCA analog audio outputs plus a choice of composite video or S-Video output. To hook up a video component for recording, you will need to connect it to both analog au- dio outputs and to your choice of video out- puts. Keep in mind that composite video input signals will not be available at the S-Video record outputs and S-Video input signals will not be available at the composite video record out- puts.
NOTE: All connections (both input and output) from a source component must be made con- sistently to the same set of connections. For example, if you designate a VCR as VIDEO 1, you must connect all of its input and output signals to the VIDEO 1 connectors.

VIDEO 1–3 Audio Outputs 
Using standard audio interconnect cables, connect the left and right channel RCA audio outputs from the RSX-1055 to the audio inputs on the source component. Make sure that you are consistent. If you hook up a VCR to the VIDEO 1 inputs, hook up the VIDEO 1 out- puts to the same VCR. Also make sure that the left channel is connected to the LEFT connec- tors and the right channel to the RIGHT con- nectors.
VIDEO 1–3
Composite Video Outputs 
If you choose to use the RCA composite video connections for a source component, use a 75 ohm video interconnect cable to connect the RSX-1055’s RCA video output (labeled COMPOSITE OUT) to the RCA video input on your VCR.
VIDEO 1–3 S-Video Outputs 
If you choose to use S-Video connections for a source component, use an S-Video cable to connect the RSX-1055’s S-Video output (la- beled S-VIDEO OUT) to the S-Video input on your source component.
Digital Source Connections
See Figure 4.
The RSX-1055 provides digital connections which may be used in place of, or in addi- tion to, the analog audio input and output con- nections described in the previous sections. These connections include five digital inputs and two digital outputs for recording.
These digital connections can be used with any source component that supplies a digital signal, such as a DVD player or CD player.
NOTE: A digital connection means that the digi- tal processors in the RSX-1055 will be used to decode the signal, rather than the source component’s internal decoders. In general, you must use digital connections for a DVD player or other component that supplies a Dolby Digital or DTS signal, otherwise the RSX-1055 will not be able to decode these formats.

Digital Inputs 
The RSX-1055 accepts digital input signals from source components such as CD players, sat- ellite TV receivers, and 5.1 channel Dolby Digital, DTS, or 6.1 channel DTS-ES signals from DVD players. The built-in D/A converter senses and adjusts to the correct sampling rates.
There are five digital inputs on the rear panel, three coaxial and two optical. These digital inputs can be assigned to any of the input sources using the INPUT MENU screen de- scribed later in this manual. For example, you can assign the COAXIAL 1 digital input con- nector to the VIDEO 1 source and the OPTI- CAL 2 digital input to the VIDEO 3 source.
Connect the appropriate cable (optical or 75 ohm coaxial) from the digital output of your source component to a digital input on the RSX-1055 and then configure that digital in- put for use with the source component using the INPUT MENU.
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 or for ZONE 2 operation
Digital Outputs 
The RSX-1055 has two digital outputs (one coaxial and one optical) to send the digital signal from any of the five digital inputs to a digital 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 or outboard processing.
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.
Connect the digital output to the digital input of your recorder or processor. You can use either a 75 ohm coaxial video cable or an optical cable.
