With Harman Kardons optional The Bridge, you can play audio, video or still images stored on your iPod (not included), use your AVR 146 remote control to operate the iPod, and even charge the iPod while its docked in The Bridge. Simply plug the propri

29、etary cable from The Bridge into the special The Bridge/DMP connector on the rear of the AVR 146. See Figure 28. Refer to the owners manual for The Bridge to select the appropriate insert to match your iPod. Figure 28 The Bridge/DMP Connector Step Five Connect the Video Display Only video connection

30、s should be made between the receiver and your video display (TV), unless your TV is the source for your television programming (see Video 2 Source, above). You will need to make a video connection for each type of video used for your sources. In addition, even if you didnt use S-video or composite

31、video for any of your sources, one of these video monitor connections is required to view the AVR 146s on-screen menus and displays. First, determine what types of video your display is capable of handling. Remember that HDMI is preferred, followed by component video, S-video and then composite vide

32、o. Ideally, this guided you in selecting the video connections for your sources. Next, note which types of video connections you used for your source devices. Make sure you didnt use a better type of video connection for a source than your video display can handle. If so, you will need to disconnect

33、 the source and use a video connection thats compatible with your display.

34、eo connection for any of your sources, then connect the HDMI Output on the AVR to an HDMI input on your video display. See Figure 29.As mentioned previously, you will need to make a separate digital audio connection from each source device to the AVR 146, and you will also need to consult the owners

35、 guide for your television to learn the proper procedure for disabling or muting the audio. Figure 29 HDMI Output If you used component video for any sources, connect the Component Video Monitor outputs on the receiver to one set of component video inputs on your display. See Figure 30. Make a note

36、of how these inputs are labeled on the display. Figure 30 Component Video Monitor Outputs If you used S-video for any sources, or if all of your sources used HDMI or component video, connect the S-video Monitor output on the receiver to an S-video input on your display. See Figure 31. Make a note of

37、 how the input is labeled. If you used composite video for any sources, connect the composite video Monitor output on the receiver to a composite video input on the display. See Figure 31.Again, make a note of how this input is labeled on the display. Figure 31 S-Video and Composite Video Monitor Ou

38、tputs Consult the manual for your TV to make sure you understand how to select each video input.As you play different source devices that use different types of video connections, select the correct video input on your video display. Step Six Plug in AC Power Having made all of your wiring connectio

39、ns, it is now time to plug each components AC power cord into a working outlet. Before plugging the AVR 146s AC Power Cord into an electrical outlet, make sure that the Master Power Switch on the front panel is popped out so that the word OFF appears on its top. Gently press the button to turn the s

40、witch off.This will prevent the possibility of damaging the AVR in case of a transient power surge. Step Seven Insert Batteries in Remote The AVR 146 remote control uses three AAA batteries, which are included. To remove the battery cover located on the back of the remote, firmly press the ridged de

41、pression and slide the cover towards the top of the remote. Insert the batteries as shown in Figure 32, making sure to observe the correct polarity. Figure 32 Remote Battery Compartment When using the remote, remember to point the lens toward the front panel of the AVR 146. Make sure no objects, suc

42、h as furniture, are blocking the remotes path to the receiver. Bright lights, fluorescent lights and plasma video displays may interfere with the remotes functioning. The remote has a range of about 20 feet, depending on the lighting conditions. It may be used at an angle of up to 30 degrees to eith

43、er side of the AVR. If the remote seems to operate intermittently, or if pressing a button on the remote does not cause the AVR Selector or one of the Input Selectors to light up, then make sure the batteries have been inserted correctly, or replace all three batteries with fresh ones. Step Eight Pr

44、ogram Sources Into the Remote The AVR 146 remote not only is capable of controlling the receiver, but it may also be programmed to control many brands and models of VCRs, DVD players, CD players, cable boxes, satellite receivers, cassette decks and TVs, as well as an iPod docked in The Bridge. It ma

45、y help to think of the remote as a book with pages. Each page represents the button functions for a different device. In order to access the functions for a particular device, you first need to turn to that page, that is, switch the remote to that device mode. This is done by pressing the AVR Button

46、 to access the codes that control the receiver, or the Input Selector buttons to access the codes for the devices programmed into the remote. You may have noticed that three of the Input Selectors look different from the others (see Figure 33). For the DVD/CD,TAPE/The Bridge and HDMI 1/HDMI 2 Select

47、ors, there is a primary source, whose name is printed on the button, and a secondary source, whose name is printed in green above the button.To access the code set for the primary source (which also selects that source input on the AVR and turns on the AVR), press the Input Selector once.The Input S

48、elector will light in red to indicate that the primary source is active. To access the code set for the secondary source (which also selects that source input on the AVR and turns on the AVR), press the Input Selector a second time.The Input Selector will light in green to indicate that the secondar

49、y source is active. The AVR 146s remote is factory-programmed to control an iPod docked in The Bridge and many Harman Kardon DVD and CD players. If you have other source devices in your system, follow these steps to program the correct codes into the remote.
