Please connect your components (e.g. DVD, SAT or CD) to the appropriate digital inputs and press FUNCTION and then rotate MULTIJOG to match your connection. Note: Optical and coax cables carry only the audio portion of the si

36、 Digital (e.g. DVD or SAT) or standard PCM (CD) format digital signals. Read section on Input Signal Setting under Advanced Sound Control carefully to adjust the matching input settings. If your CD player is equipped with digital optical jacks, use of optical cable is preferred. What you need is jus

37、t one more optical digital connecting cord(not supplied). Plug it in the digital input jack of the receiver and select OPTICAL on the receiver setting (see details on pg 20 chapter Input Signal Setting). You can enjoy better sound quality brought to you by the optical cable. When optical cable is us

38、ed, analog cables are still needed for recording to tape output. Note: This receiver has one digital optical jack only. Be sure that such connection does not prevent optical cable connection of other components (e.g. DVD & SAT) S-VIDEOIf your video component has a S-Video jack included, you can make

39、 use of it to enjoy enhanced video quality by connecting it to the relevant S-Video jack at the rear side of the receiver. One video cable is needed for each component. When S-Video cable is used, composite video (yellow RCA connector) cable must also be connected for VCR recording.Note: Before plug
