Receiver Shuts down at 45 level

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.

Re: Receiver Shuts down at 45 level

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.

Re: Receiver Shuts down at 45 level

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.

I have Onkyo TX-SR304E receiver, it plays find on low volume, however when it is on 40 or above after some time the unit shuts off? How can I fix this problem? Regan

Check the impedance of your speakers. It sounds like the amp is getting overloaded and shutting down either for over current or over heating.
Most common issue is a partially blown speaker or crossover.
Sometimes it's just a rogue strand of wire, and reconnecting everything fixes it.
But measure the impedance on all the speakers anyways!

How to program remote control?

Your Onkyo TX-SR304 receivers remote (RC-645S) is not capable of controlling devices by other manufacturers. It controls only Onkyo devices.
Other Onkyo remotes do have universal remote functionality and you can download Onkyo remote codes here.

I hope that helps.

I have a onkyo tx sr304 and a onkyo 6 disc player dx-c390.When my cd gets to disc 4 and 5 it shuts the receiver down.Whats up with this?

The only possibility that comes to mind is that it may be causing a short somehow when the carousel gets to that position, maybe a broken solder joint. Another possibility is that there may be a foreign object stuck inside the player such as another disc that lost it's position.

Need codes for universal remote

Not sure if this helps, but I just called Onkyo with a request for codes for the SR304. They said the only codes they have are for THEIR remote. Maybe they will work with yours. Here they are:
0276 0476 0810 1187 1376.
I tried these in the Comcast remote (adding a 3 in front of the numbers) but that didn't work. Still trying to get my Comcast remote to program the Onkyo SR304 adequately, since their published codes only partially work.

Very low ouput from subwoofer preout

The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
