REAR-PANEL CONNECTIONS 6-/8-Channel Inputs: Connect the multichannel analog audio฀outputs฀of฀a฀non-HDMI฀player฀(DVD-Audio,฀SACD™, Blu-ray Disc™ or HD-DVD, or any other external decoder) to these jacks. Coaxial 1/2/3 and Optical 1/2/3 Digital Audio Inputs: If a source has a compatible digital audio output, and if฀you฀are฀not฀using฀an฀HDMI฀connection฀for฀audio฀for฀the฀device,฀ connect it to one of these jacks to hear digital audio formats, such as฀Dolby฀Digital,฀DTS฀and฀linear฀PCM.฀Use฀only฀one฀type฀of฀digital฀ audio connection for each source. Coaxial and Optical Digital Audio Outputs: If a source is also an audio recorder, connect one of the Digital Audio Outputs to the recorder's matching input for improved recording quality.฀Only฀PCM฀digital฀audio฀signals฀are฀available฀for฀recording.฀ Both coaxial and optical digital audio signals are available at either Digital Audio Output. XM Antenna Jack: Plug฀in฀an฀XM฀Connect-and-Play฀or฀ Mini-Tuner฀antenna฀module฀here.฀ Network Jack: Plug฀in฀an฀RJ-45-compatible฀cable฀that฀connects to a personal computer (PC), router or Internet access. When connected to a PC, the AVR 7550HD is capable of playing audio and JPEG฀files฀stored฀on฀the฀PC.฀When฀connected฀to฀the฀Internet,฀the฀ AVR 7550HD may be used to enjoy Internet Radio. See pages 36 and 37 for more information. RS-232 Serial Port: This bi-directional port may be used to control the AVR 7550HD using an RS-232 serial control link to a compatible computer or programmable remote control system. Due to the complexity of programming RS-232 commands, connections and programming for control purposes should be performed by a qualified custom installer. Trigger 1 and 2 Outputs: Connect these control jacks to the trigger input jack of an external component, such as an audio power amplifier, that you want to power on any time the AVR 7550HD is turned on, without using the AVR's Switched Accessory Outlet for power. When this connection is used, the AVR 7550HD will automatically send a low-voltage signal to the connected device that triggers it to turn on when the AVR 7550HD is on, and off when the AVR฀7550HD฀is฀placed฀in฀the฀Standby฀Mode.฀The฀connected฀component must respond to 6-volt presence as the control signal. The Trigger 2 Output may be programmed to transmit its signal only when certain of the AVR's source inputs are selected. For example, to lower a screen when watching a DVD movie, but not while listening to the tuner, connect the Trigger 2 Output to the screen and program it to be on when the DVD source is selected, but off when the฀AM,฀FM฀or฀XM฀bands฀are฀in฀use.฀See฀the฀Initial฀Setup฀section฀for฀ more information on programming this setting in the Info Settings menus for each source. Zone 2 Infrared (IR) Input: Connect a remote IR receiver located in the remote zone of a multizone system to this jack to control the AVR (and any source devices connected to the Remote IR Output) from the remote zone. Remote Infrared (IR) Input and Output: When the remote IR receiver on the front panel is blocked, connect an optional IR receiver to the Remote IR Input jack. The Remote IR Output may be connected to the Remote IR Input of a compatible product to enable remote control through the AVR. Remote IR Carrier Output: This output is similar in function to the Remote IR Output, with the difference that this jack outputs the full infrared signal as received by the AVR's IR sensor or the Remote IR Input, while the Remote IR Output jack outputs a "stripped" signal that has no carrier frequency. HDMI Inputs and Output: HDMI฀(High-Definition฀ Multimedia฀Interface)฀is฀a฀connection฀for฀transmitting฀digital฀audio฀ and฀video฀signals฀between฀devices.฀Connect฀up฀to฀four฀HDMIequipped฀source฀devices฀to฀the฀HDMI฀inputs฀using฀a฀single-cable฀ connection. When฀you฀connect฀the฀HDMI฀Output฀to฀your฀video฀display,฀the฀ AVR 7550HD will automatically transcode analog video signals to the฀HDMI฀format,฀upscaling฀to฀as฀high฀as฀1080p.฀ NOTES: When connecting a DVI-equipped display to one of the฀HDMI฀Outputs Use฀an฀HDMI-to-DVI฀adapter Make฀sure฀the฀display฀is฀HDCP-compliant.฀If฀it฀isn't,฀do฀not฀ connect฀it฀to฀an฀HDMI฀Output;฀use฀an฀analog฀video฀connection฀ instead Always฀make฀a฀separate฀audio฀connection. Analog 1 - 5 Inputs: Connect the left and right analog audio outputs of a source device to any of these inputs. These inputs may be paired with any video inputs. NOTES: •฀฀The฀Analog฀3฀and฀4฀inputs฀are฀each฀associated฀with฀a฀set฀ of outputs. Consider using these connectors for an audio or video recorder. •฀฀You฀may฀optionally฀connect฀a฀source฀to฀both฀an฀analog฀and฀ digital audio input. This is useful for making recordings, for multizone applications or simply as a backup. Analog 3 and 4 Outputs: Connect either of these analog audio outputs to the analog audio inputs of a recording device. A signal is available at these outputs whenever an analog audio source is playing. Zone 2 Audio Outputs: Connect these jacks to an external amplifier to power the speakers in the remote zone of a multizone system. Subwoofer 1 and 2 Outputs: If you have a powered subwoofer with a line-level input, connect it to the Subwoofer 1 Output. For improved performance, connect a second powered subwoofer to the Subwoofer 2 Output. The Bridge II Input: Connect the included Harman Kardon docking station to this input for use with most docking iPod models, 4G and later (not included). Turn the receiv- er off (Standby mode) when connecting The Bridge II. 11
