When I am listening to either my DVDs or CDs my Onkyo TX-SR304 receiver powers off. This powering off normally occurs when I have my volume between 45-50. I have 15 year old Sony speakers as my front speakers, 2 rear speakers and a center speaker connected. One sales rep from an electronics retail store says it is that the receiver is too powerful for the speakers. Another sales rep says just the opposite, that the speakers are too powerful for the receiver. I've only had this receiver for a month. Any suggestions are appreciated. Thank you! ps. What would adjusting the individual speaker volumes do for this situation? I have a surge protector but one sales rep suggested I get a new one costing $149 that is especially made for Home Theater systems.
I was having a similar problem and I found that the positive and negative speaker wires were touching on the speaker connections made in the receiver.
Before I bought anything new, I would check a couple of things: 1 - Is there a problem with heat buildup? Receivers can put out a lot of heat, and if it's in an enclosure without adequate ventilation it can cause problems. 2 - Does the receiver have a switchable impedence setting for speakers? If so, make sure that the impedence matches. 3 - Is the speaker polarity correct? Make sure that the + and - on the receiver matches the posts on the speakers. To rule out problems with speakers and connections, you can try disconnecting all the speakers and running the receiver to see if it shuts down.
