I have a Pioneer VSX - 415, but get the message "Overload" as soon as I turn the volume up just a little.
What can I do??
There are several things you can do, but taking the simplest things first into consideration.
Wiring. If you have any loose speaker terminal connections at either end, or any stray strand wire near the receiver chassis it can cause this problem. It's likely that this is actually NOT the case in your particular situation as it appears to be volume control related, but this condition will also cause an overload message as well.
Speakers...lack of efficiency/sensitivity, high or otherwise unstable Ohm rating will require more power. Ohm ratings are based on a nominal impedance (resistance) of a specified input voltage by industry standards, and can vary considerably with signal frequency. Higher impedance occurs as input frequency is decreased...more on this later.
System setup. How many speakers are connected? Each terminal is designed for one channel connection. If you have multiple speakers, i.e.; spliced in series such as with separate enclosures that have multiple drivers, this increases the resistance and power consumption dramatically.
After the above considerations are addressed and resolved but you are still experiencing the problem, do one or all of the following;
Check your audio configuration. If your system has an equalizer, loudness control or "bass boost", turn them off. More bass requires more power from the amplifier, thus can be a cause of the overload you are experiencing.
Adjust your crossover. If you are using an active subwoofer, increase the crossover frequency point in the speaker setup menu of the receiver. You may or may not have to set your other speakers' setting to "small" to enable the digital crossover feature, but setting them to small is preferred in your case. This will allow the subwoofer (if an active one) to handle a broader spectrum of the bass frequencies, rather than the speakers that are being powered by the receivers' amplifier that is currently being overloaded. It will also improve the sound quality. You however, do not have to have connected nor use a subwoofer to do this type of setup, simply increasing the crossover point will omit some of the lower frequencies that are putting higher demand on the amplifier. Alternatively, you may also increase the crossover frequency at the source material, such as your CD or other player instead of in the receiver.
