No sound from subwoofer

Make sure your front speakers are set to small in the setup menu. Regardless of how large your speakers are, if they are set to large the receiver will put the low frequency sound out the speaker jacks and turn off the subwoofer output

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...

I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

Hi! 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?? Eyvind

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.

Old receiver, new subwoofer- how to connect?

NOOOOOOOOOOOOOOOOOOOOOOO! Never connect speaker outputs to anything that looks different, like RCA connections. Can you say crispy critter?

Your receiver sounds like it won't send specific Subwoofer of Low Frequency Effects information to the Sub so we're cheating by adding a sub. If you named the model of each we may have a better shot at naming the output you need to use.

I'm curious. How did you have the old passive sub working?

Basically what you may have to do is feed (probable) full range audio to the Sub using an RCA splitter to combine the L and R outputs found, oh, at any Tape Output that you're not using. The Sub will only reproduce what it can. The presence of higher frequencies won't bother it. If it has its own volume control you'll be able to balance its volume with the rest of your speakers.

I get no bass sound from sub-Woofer connected to Yamaha RX-V465

Check your speaker settings in Setup menu / Speaker Setup / Manual / Config (and then in this submenu also Equalizer).
In Config, choose where should low frequency sound go - subwoofer and/or front speakers (if they are big enough). The settings are: Bass Out: SWFR/Front/Both.
Also check Subwoofer phrase in SWFR Phase.
Check settings of all speakers, they can be Large / Small / None. If small, frequencies lower than "Crossover" settings, will not be put on them.

Subwoofer does not kick in during stereo mode with front speakers

There should be an adjustment in setup that for 2 channel sources, you may have to enable the subwoofer output. Or alternatively, if the subwoofer output for 2 channel sources is in fact enabled, then increase the crossover frequency for the sub.

Sony str de545 5.1

Make sure the subwoofer is set to On in the setup menu. Should be able to access this setting from the front panel, using the click wheel and the left/right buttons above the wheel. Push the setup button to get to the right menu. Set subwoofer to 'on' and speaker size to 'small'. This receiver has a fixed crossover, so make sure to turn the crossover setting on the subwoofer to the maximum setting (highest frequency) to ensure no signal is lost.

Subwoofer-no output

ther should be a diagram in the left hand corner of display of speakers hooked up, make sure sub is shown right under the left right (and possibly) center speaker icons. under adjust, there is a subwoofer volume level. Under settings there is sub (yes, and no for on and off) there is a sub crossover frequency, and i believe there is also a "LFE" att, which is another subwoofer level.

If there is "large/small speaker" settings on your receiver, maybe you set speakers on Large. Some receivers, when set speakers to "large", won't redirect signal on subwoofer.
