Question about Audio & Video Receivers

Open Question

Sansui SAN0506 HI I've got a Sansui SAN0506 receiver (yes I'm sure it is the correct model but googling this I can not find ANYTHING online about this model). Problem is that it produces a high-pitched noise, but ONLY on a DIGITAL INPUT (this one has 2 coaxial and 1 optical, problem occurs on all 3) - but not on any analog inputs. It does this with any and all combinations of speakers attached, a multitude of input sources attached or only 1. I've got 2 devices that produce digital out, a settop box and a DVD player and it happens with both. There was a cluster of 3 capacitors that I've already replaced because it looked like one of them had leaked - I've replaced with capacitors with exactly same voltage and capacitance values.  I got it second hand and I'd just go the analog route - if only it had 5.1 analog inputs which it doesn't :-( The only way I can get any surround out of this baby is with digital inputs.

Check you settings on the receiver. get into the menu of the unit and check the "Audio" settings. if you can choose by specific input, select "Digital" otherwise, select "Auto" that should correct the problem. If you still have a problem, post a comment and I can help you troubleshoot some more.

Each digital input is assigned a name and a function by you. You have to dig out the manual and assign the digital inputs.

My $.02. Why do you not want to use the coaxial imputs? There is no functional superiority of one over the other BUT coaxial is a) cheap, since it uses standard RCA cables; b) adaptable, since you can splice or split them among two devices; c) not delicate or prone to failure due to tight bends. I share one coaxial input between two digital device with an RCA splitter cable. Just have to make sure to turn the one I'm not using OFF. Try that with optical.

SOURCE: Crackling and saturation in frequency of surround speakers

I have the same tuner with the same problem. I have 2 pairs of Bose Acoustimas speakers and a pair of their sub woofers. I found it was the vibration from the subwoofers were causing so much vibration even using monster wire the crackling was caused by wire vibration at the speaker or subwoofer. if you are using twisted wire with a banana plug on the end or straight twisted wire into the speakers the constant vibrartion eats into the wire. Just pull the wires out re twist or tin (solder) the tips or move to a different location on the banana plug and really twist it will getting a bite into the wire. If you are using straight banana plugs use a screwdriver in the 4 slots to make them fatterso they stay tight. if they are RCA jacks pinch down the 4 outside tabs so they grip harder. Viva La France.

Device will not operate. computer says it is not connected.

First check to see if the computer is even recognizing it at all, if not then you should search on google or online for the correct drivers for the receiver. If this is a surround sound system then it might need a special connection like mine did. Receivers use digital sound and require a optical connection or coaxial connection so check up on that too!
