Question about Onkyo TX-SR503 Receiver
Hi, First, sorry for my bad English, I am French and have not written english for a long time :(. I need help to repare my TX-SR503E tuner amplifier. When I use surround speakers (speakers group A), I have the sound but with crakles and saturation in frequency. The problem occure as well with digital inputs (optical or coaxial) as analogic inputs. I can't either use the way of functionning "pure audio", it is nos available since I have this problem. On the other hand, the speakers group B with analogic input (impossible to use digital input with group B) perfectly works. I thought to a dysfunction in power relay but there is 5 and 2 are used to speakers groupe B too. Ideas ? Thank you in advance for everything Matthieu
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.
