Question about Pioneer VSX-815-K Receiver

3 Answers

Overload Probs. Even upon initial setup, the recvr. would overload and shut down @ vol. -30 (not very loud). I have two bookshelf speakers rated @ 120w 8 ohms. Now, (2yrs.later) it overloads when vol. is above a whisper. This happened after my friend was dusting behind the speakers and knocked one of the wires out and I reconnected. Wires are not crossed. I have reset to factory settings and it still overloads. I have been told to replace the speaker wire because that is shot. I have not done that because I don't buy it. I was also told the rcvr. is fried. I don't buy that either. Please help. I am ready to bash the bloody thing. If you need more info.I would be glad to assist. Thanks, -Dee

I am not sure which wire did you reconnect .

Just have look at the connection of wire which you connected is it towards amplifier .

Did you hear any kind of noise after connecting the wires ?

Disconnect one speaker, either left or right, and check does receiver go to overload?
one of two speaker is bad in this case.

Protection overload and the system shuts off


Reasons: 1. Short in the wire, speaker, or amplifier 2. Amplifier malfunction 3. Overload of the amplifier 4. Overload of the speaker
Listening to audio at loud levels requires more power obviously. But the speakers and amplifier may not be rated or capable to handle it due to age or design.

Tip

My Pioneer displays Overload


Overload is displayed when the amp draw is excessive, and can be caused by different faults.
when Overload is detected, the protection circuit will shut down the unit to prevent further damage.

The first thing to try is hard reset. Shut down the unit for about one hour to drain power completely.
This can fix minor problems that can cause overload, for example electrostatic charge accumulation on internal capacitors.

If that does not fix the problem, then you must find the fault.

Overload can be caused by shorted speakers, wrong impedance speakers, or by a contact on speakers wiring.
Check speakers connection and test different speakers with 6, or better 8 Ohms impedance.

Another test can be done by unplugging all speakers, and reconnecting and testing them one at a time, at a very low volume.

If the speakers are OK, then preamp, shorted input/output connectors, main power supply or faulty output transistors can draw too much amps causing overloading.

In that case it is recommendable contacting Pioneer at the number listed on the owners manual.

No more than two 4 Ohms speakers can be connected to the unit, or you will get overload.

If the speakers are OK, then preamp, shorted input/output connectors, main power supply or faulty output transistors can draw too much amps causing overloading.

In that case it is recommendable contacting Pioneer at the number listed on the owners manual.

Overload protection


Doe this always go into overload independent of the volume level? Try disconnecting the speakers completely and running the set. Does the set shutdown then too?

Thanks,

I have a Technics SA-AX610 receiver that says overload .


From the manual pg 27....... "The protection circuitry has functioned because the positive and negative speaker connection wires are "shorted," speaker systems with an impedance less than the indicated rated impedance of this unit are used or under severe use, such as loud volume, excessive power and in an excessively hot environment."

Overload...


Pioneer posted this on it's Canadian Web Site:

Poor wiring connections, bad wires or a bad speaker may cause this. As you increase the volume, you will increase the amount of current you are drawing from the receiver. To troubleshoot this issue, try the following:
  1. Disconnect each speaker wire connection. Inspect for any frayed or damaged wiring and replace it.
  2. Check the impedance of the speakers; make sure they are properly rated for your stereo. In most cases, they need to be 8 ohms. Only a few Pioneer receivers will support lower impedance.
  3. If the problem still continues, try these steps:
    1. Turn the receiver off.
    2. Remove one speaker.
    3. Turn the receiver on.
    4. Increase the volume.
If the receiver overloads, repeat steps 1-4 (selecting a different speaker each time). If you disconnect a certain speaker and the receiver no longer overloads, have this speaker checked at a service center. It could have a bad speaker component, like a tweeter, sub-woofer, or even a bad crossover.

Overload


I know that this post is long outdated, but I came across it and had to post.  Sorry, but the solution posted by nfanres is not correct.  Just because the KLH speakers are rated at 250W does NOT mean that they will always pull that much from the receiver.  That is just a manufacturer rating saying that they recommend supplying a max of 250W to the speakers.  The reason your receiver says "Overload" is most likely due to the subwoofer being an improper impedance for the receiver, causing the receiver to see a lower resistance in the load, and thus outputting too much power.  I could go into a detailed explanation as to why with Ohm's Law, but just suffice it to say that if you decrease the resistance, current will increase, thus the overloading (too much current draw for the receiver).
If you haven't already, try just unhooking the sub and going back to the setup you had before.  Generally, Pioneer receivers are protected, and just say "Overload" and shut down everything so that nothing fries.  If you have already tried that, then I don't know what to tell you - something must have internally tripped.  You have probably either gotten rid of the receiver or fixed it by now, but I just had to post and clear this up for anyone else who might have a similar problem.
In short, ratings on the backs of speakers do NOT mean that they pull that much power.  It's just a rating of how much you can push from the receiver to the speaker.
