Question about Pioneer Sx-251r Stereo Receiver

Open Question

The receiver in question is a Pioneer SX251R. The speakers are all 8 ohm. The problem is that the speakers inadverdently cut out along with a static sound. It happens on both the A and B speaker sets. How can I troubleshoot this problem? Does the receiver require a good ground wire?

SOURCE: Pioneer VSX-505S Subwoofer Installation

That type of subwoofer is not used with this receiver. This receiver actually outputs no power for a subwoofer, therefore only needs a plain ol' rca signal wire. This is due to the fact that you need a powered sub... one that you plug in to the wall and it has its own built in amp. you simply run an rca from yyour 505s to that sub.

If it's under warranty..get a new one.
It's an internal breakdown ...tech service only.

SOURCE: pioneer vsx-519 no sound from center and surround

Make sure that the sound field/programme you have selected is dolby digital not stereo.(On the amp)
You also need to check on the display that is says DIGITAL not ANOLOUGE, as only a digital input, Optical fibre cable, HDMI, COAX will be a digital signal.
If you are using red and white rca connectors, it is not going to work, as this is an Anolouge signal.

SOURCE: pioneer sx-255r can i connect 6 - 8 ohms

Yes, you can use them but be careful. These are not necessarily robust speakers. If they sound strained, back off.

Pioneer receiver overload


The "Overload" message usually involves the speakers or the speaker wires. Disconnect the speaker wires and make sure that they aren't frayed or damaged. (When you reconnect them, make sure that no loose wire touches the receiver case, speaker or another wire.) Replace any damaged wire. Make sure that none of your speakers have a lower impedance than the receiver can handle. (Most Pioneer systems have a 8 ohm limit.)

If the message persists, turn off the system. Disconnect one speaker at a time and try turning on the receiver and turning up the volume. If the error disappears when one speaker is removed, that speaker may be damaged and needs to be serviced. Do not reconnect the speaker to the receiver until it is fixed.

I hope this helps.

Is it totaly ok to just connect one pair of JBL Control 1 speakers to this receiver? Here are some of the specs. Frequency Response: 120 Hz to 20 kHz Power Capacity: 150 W Sensitivity 87 dB SPL Nominal...


The only relevant speaker spec is the impedance. As you probably realize the Pioneer SX-255R recommends 8 - 16 ohm speakers.

Four ohms is on the hairy edge of too low. You could certainly try it but if any strain or excessive volume is used you could see something go poof!

The low end of 120Hz says don't push the bass to them.

hi,
First of all you have to check the speakers impedance. It should be 8 Ohms.
if the Ohms of the speaker is lower than 8 Ohms, it will overload the amplifier and will over heated and will switch off to prevent further damages. try to use speakers which have impedance of 8 ohms.
ok

Testing your amp at max with the speakers disconnected will not play a factor because there is no power being drawn so the amp is not being used. Those speakers are rated 90db and really pound but also draw a ton of amps. The key thing here is to keep it cool, cool, cool. Put a fan on it and keep your receiver on a hard surface with nothing stacked on top or anywhere within a foot of it. Keeping it cool will help prevent overloads or (protection mode). Back it down every now and them and give the system a rest for a few minutes. Double check the negative and positive connection on the speakers to the receiver. We all have hooked them up backwards sometime and this will have the effect you are expressing. What is the phase set at on your receiver? Set it down to "0" and go up to where it sounds best without distortion. One more very important thing. What is the Ohm switch on your receiver set at? Put the switch on 8 Ohm even though your running 6 Ohm speakers. That switch only steps down your voltage feed to the power selections which will hamper the overall dynamics and fidelity of your receiver. This switch is really not even necessary. Putting that switch at 8 Ohms will give you more headway and aid in keeping your amp cool.

Overloads with volume a third od the way up,i have 2 12 inch cerwin vegas hooked to it


fan_of_tony,
There is not much info in your question to properly answer it but here are a few things.

1) The VSX-D307 is a home receiver that is rated for no less than a 4 ohm load. If you have two 12" 4 ohm CV subs on the same channel and they are in parallel, that would create a 1.7 ohm load which would easily cause the problem.

2) If you have one on each channel connected along with speakers that are for you mids and highs, the way they are connected could be reducing the resistance load the amp will see which would easily cause the problem.

3) If you have one on each channel and no other speakers the problem would be simply that your speakers can use more power than the amp can produce. Thus you are able to raise the volume of the amp passed it's maximum output which would cause the amp to clip and the amp will go into overload protection.

4) Your receiver has an 8 ohm rated amp. Which means it can run at 4 ohms but the amp will produce more power at lower volumes on the knob setting and will max out at lower levels than if you were using a 8 ohm speakers.

In short, CV's can use a lot of power and your receiver, regardless of advertised power levels, cannot give the speakers what you are looking for in sound levels. Buy a larger dedicated amp for the CV's as the clipping from your Pioneer receiver is doing damage to your CV's. Your speaker's can hear the clipping before your ears can so damage will start to occur before your ears can hear the clipping.

I am buying a pioneer vsx-d414 receiver and want to no if it will drive my cerwin vega e-712 speakersv says for receivers rated 8ohms or lower.. , just currious


Yes the Pioneer will drive the Cerwin Vega speakers. The Pioneer requires at least 8 ohm speakers and if the Cerwin Vega speakers are 8 ohms, it won't be ******* the receiver.

The speakers you have are high wattage, so the Pioneer may not be able to get the most out of them, but it should be pretty good.

It is always good to have speakers rated at a higher wattage than the receiver, that way the receiver will not fry the speakers. No matter what the wattage of a speaker, it will not pull more power out of an amplifier than the amplifier is capable of delivering. Some people have a mis-conception that if a speaker is higher rated that it will blow up the amp, this is just not true. Speakers do not pull power from an amp, they only put out as much power as the amp is pushing into them. But you can blow up an amp by driving it too hard for too long of time. They just get too hot and the heat stresses the amp circuit after a while.

I hope this helps.

Pioneer sx-205 gives a overload warning and cuts in and out when tuner or cd is playing


Does it play normal on any sources, or do you only have the tuner and CD for available sources?

There are many different things that can cause this type of problem.

It could be bad solder connections on in the amplifier circuit or power supply, it could be a bad speaker or a bad output channel inside the receiver if this happens only when it gets turned up loud.

The overload warning happens when the amplifier circuit has excessive current or DC voltage on the outputs. Unfortunately the only way to determain if it is the speakers is to change them with other known good speakers and see if it still happens. But before buying any speakers you need to have the receiver ruled out as the source of the problem.

It can also go into overload if you have the wrong type of speakers connected, or too many speakers connected. Each speaker jack should only have one speaker connected toit. If you are using for example, 4 speakers connected to the "A" speaker jacks meant for just 2 speakers, it will create a load to the amplifier that the amplifier is not rated for.
Look on the back of the receiver and it will have listed the proper impeadance for your receiver. Most will say:

8 ohms or more "A" or "B" speakers
16 ohms "A" and "B" speakers

That means you must use 8 ohm or higher ohm rated speakers if you are using only speakers"A" or only speakers "B", but can not use 8 ohm speakers if you are using speakers "A" and "B" at the same time. Then they must be 16 ohm speakers.

Two 8 ohm speakers in one speaker jack is a 4 ohm load, that is why you can not use more than 1 speaker per speaker jack.

I hope you found this information useful, and if I can be more help just let me know.

This is not a pioneer vsx-454 receiver problem


I would not recomend doing this because the 4 ohm speaker is not enough to offset the 32 ohm speaker and the amp will have problems keeping up with the power consumption of the speakers and will eventully overheat and cause damage! (it will work but not well and not without risk to your amp!)
Please rate this quick response
Thank
You!
