- Analog -- uses the A/V input from an Audio/Video device … for example, DVD, CD, SAT, or VCR
- Digital -- uses the Digital connection input … for example, Coax, Opt. 1 & 2
- 5.1 -- uses the 5.1 Audio inputs … Surround L, Surround R, Subwoofer, Center, DVD 5.1 CH front R/L
If you want true 5.1 sound, then you must use the 5.1 inputs. That means the Video unit (like a DVD) must have the 5.1 outputs (Surround L, Surround R, Subwoofer, Center, DVD 5.1 CH front R/L).
RadioShack does not currently sell a video unit with 5.1 outputs; our video devices have only Digital and Analog connections. The only way to use devices without 5.1 outputs with the 5.1 inputs is to use a 5.1 Decoder. Even if the source is encoded in 5.1, video devices can not communication communicate this information to the receiver without specific 5.1 outputs; the receiver cannot decode 5.1 information from either the Digital or the Analog inputs.
The button on the front of the receiver or the 5.1 button on the remote is for selecting the 5.1 inputs; if nothing is connected to those inputs, there will be no sound. The other connections are digital or analog. When you connect the video device (DVD or SAT) to the digital input and /or analog inputs (A/V) and use SIGNAL SELECT on the remote, you are switching between those inputs. DIGITAL selects the digital inputs, and ANALOG selects the A/V inputs. If you do not connect a video device to the ANALOG inputs (A/V) but you do connect to the DIGITAL (OPT.1) and then use the SIGNAL SELECT button to select ANALOG SIGNAL, there is nothing there as you have are not using the A/V inputs.
It is recommended that you connect both digital and analog inputs if you have the outputs available. Not all programs are broadcast in digital and some analog signals are in Dolby® Surround Sound; however, if the signal is digital, then the DIGITAL light comes on.
The best way to test the system is use the TEST TONE feature. If you get sound through all of the speakers, then the system is hooked up right. Try to adjust the speaker volumes individually. There are different Dolby® sound systems, so you must know what you are listening to -- PROLOGIC, SURROUND SOUND, DOLBY® DIGITAL .
Look on the item you are playing or watching (CD, Video, DVD or program listing) … that will help determine what encoding (if any) is being used.
