Rear Panel Connections

Coaxial Digital Inputs: Connect the coax digital output from a DVD player, HDTV receiver, LD player, MD player or CD player to these jacks. The signal may be either a Dolby Digital signal, DTS signal, a 2 channel MPEG 1 signal, an HDCD data stream or a standard PCM digital source. Do not connect the RF digital output of an LD player to these jacks.

HDMI Inputs: Connect the HDMI output of video sources such as a DVD player, set-top box or HDTV tuner to either of these jacks.

Video 2 Audio Inputs: Connect these jacks to the PLAY/OUT audio jacks on a second VCR or other audio or video source.

Video 3 Audio Inputs: Connect these jacks to the PLAY/OUT audio jacks on any audio or video source.

Video 1 Audio Inputs: Connect these jacks to the PLAY/OUT audio jacks on a VCR or other audio or video source.

Video 1 Audio Outputs: Connect these jacks to the RECORD/INPUT audio jacks on a VCR or any other Audio recorder.

Preamp Outputs: Connect these jacks to an optional, external power amplifier for appli- cations where higher power is desired.

Surround Back/Multiroom Speaker Outputs: These speaker terminals are normally used to power the surround back left/surround back right speakers in a 7.1 channel system. However, they may also be used to power the speakers in a second zone, which will receive the output selected for a multiroom system.

To change the output fed to these terminals from the default of the Surround Back speakers to the Multiroom Output, you must change a setting in the Multiroom Menu of the OSD sys- tem. See page 55 for more information on con- figuring this speaker output. In normal surround system use, the brown and black terminals are the surround back left channel positive (+) and negative (–) connections and the tan and black terminals are the surround back right positive

(+) and negative (–) terminals.

For multiroom use, connect the brown and black SBL terminals to the red and black connections on the left remote zone speaker and connect the tan and black SBR terminals to the red and black terminals on the right remote zone speaker.

RS-232 Port: This jack may be used to con- trol the AVR 745 over a bi-directional RS-232 serial control link to a compatible computer or programmable remote control system. Due to the complexity of programming RS-232 com- mands we strongly recommend that connections to this port for control purposes be made by a trained and qualified technician. This jack may also link to a compatible computer to upgrade the software and operating system of the

AVR 745 when appropriate upgrades are available.

Fan Vents: These ventilation holes are the output of the AVR’s airflow system. To ensure proper operation of the unit and to avoid possi- ble damage to delicate surfaces, make certain that these holes are not blocked and that there is at least three inches of open space between the vent holes and any wooden or fabric surface.

DVD/Video 3 Component Video Inputs: These inputs may be used with any source device equipped with analog Y/Pr/Pb or RGB component video outputs. The factory default is for these jacks to be a linked to the DVD input, but you may change the setting at any time through the IN/OUT SETUP menu. See page 14 for more information on configuring the component video inputs.

Remote IR Carrier Output: The output of

this jack is the full signal received at the Remote Sensor Window ¯ or input through the Remote IR Input including the carrier frequency that is removed from signals at the Remote IR Output . Use this output to extend IR remote signals to the input of compatible products by direct connection or through the use of optional, external IR “blasters”. If you are in doubt as to which of the two IR Output jacks to use, we recommend that you consult with your dealer or installer, or check with the manufacturer of the external equipment you wish to control.

Subwoofer 2 Output: If your system has two subwoofers, connect one to Main Subwoofer Output , and connect the line level input of a second subwoofer to this jack.

Digital Media Player (DMP) Connector: With the AVR 745 turned off, con- nect one end of the optional Harman Kardon to this proprietary connector, and the other to your compatible Apple iPod. When the Digital Media Player source is selected, you may view your iPod’s control and navigation messages on your video display (if one is connected to one of the Video Monitor Outputs ), and in the Upper and Lower Display Lines ˜. You may navigate the iPod and select tracks for playback using the ⁄¤‹ › Buttons DF, the Set Button EQ and Transport Controls 9P on your AVR remote. See page 50 for more information.

Trigger 1 Output: Connect this jack to the “Trigger In” jack of an optional external compo- nent such as an audio power amplifier that you want to be controlled to mirror the power state of the AVR 745. When this connection is used, the AVR 745 will automatically send a low-volt- age signal to the connected device that turns it on when the AVR 745 is on and off when the AVR 745 is placed in the Standby Mode. The connected component must respond to 6-volt presence as the control signal.

Trigger 2 Output: Connect this jack to the “Trigger In” jack of an optional, external compo- nent such as a projection screen or motorized blinds that you want to turn on or off in response to the power state of the AVR 745, but only when certain inputs are selected. (For example, lower a screen when a Video related mode is selected, but not for the tuner or a CD player.) For the 5-volt control signal to be sent to the jack for device control, you must activate the appropriate setting in PAGE 2 of the IN/OUT SETUP menu. See page 19 for more information.

Multiroom Video Output: Connect this jack to the cable and/or optional, external video distribution system that delivers the video source selected for multizone distribution to remote rooms. Only composite video is available.
