Only surrond works 0n stero reiever front a and b doesnt


Verify the main speakers are not blown or cables damaged or disconnected. If you have an ohmmeter, set it to ohms and measure across the speakers with no cables connected. You should see 3-9 ohms. Anything higher will indicate problems in the speaker(S). Get them reconed or replace defective speakers.

If the speakers test ok, remove the cables from the amp and speakers. Test your speaker cables by shorting both wires together on one end of the first cable. Connect the ohmmeter, set to ohms, to each wire on the opposite end. You should see near 0 or maybe 1 ohm. If not, the cable is open. Do the same with the other cable.

If these tests all pass, you have a more serious problem in the amp. You will have to take it to a reputable shop. Good luck!

Stero says overload and shuts down


Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.


Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

I have an old SHARP HK-9000 Multi-purpose Music syatem...we cant find speaker connectors on the rear. The speakers are detachable and dont have input jacks, just bare wires. Where do they connect??


The speaker wire is supposed to be connected to a mono right angle 1/8" male plug. It resembles the same plugs at the end of headphones used for all sorts of walkmans, cd players, mp3 players... But the plug on your speakers is mono so instead of there being two bands on the plug for stereo, you need the mono variety, the one with one band. They plug into two small female holes located on the bottom rear of the boombox. You might see some small black plastic clips along the bottom of the boombox held in place by one screw. These things are meant to keep the speaker wire from hanging out from the bottom of the boombox.

I am trying to hook up a powered sub woofer to a yamaha rx-v461 and i dont know what cables go where on the back of the sub there are two speaker ports and there are two plug ins but each speaker port has...


Your subwoofer probably has both high-power inputs and "normal"low inputs. The first are for receivers, which don't have link-level output for sub, so they are able to take already amplified signal as input.
You need to use link-level input of your sub and connect it to subwoofer-output of your receiver. The output is marked as OUTPUT - Subwoofer and is black-color RCA plug (don't confuse with subwoofer INPUT under MULTI CH INPUT).
Receiver has only mono output for subwoofer. If your sub has stereo input (white/red RCA plugs), connect just the left channel to the receiver, it will still work.
Don't connect anything to the speaker output on the sub, you don't need that.

I have a theater logic home cinema subwoofer


i do not have this system however i did look up a picture and i can see rows of red and white Mono speaker inputs this is where you would plug in your Mono speakers it does not look like stereo speakers will work plug one mono speaker in a red the other in white i cannot see a port to use it for a computer but if there is look for a round 3.5mm stero jack and if u find one you must have a 3.5mm auido to 3.5mm audio cable put one side in the system and the other in the headphone jack of your computer

two 8 ohm speakers in parallel is 4 ohms.
if series 16 ohms.a high resistance will just produce less power.
too low a number can activate the speaker protect,or blow the amp.
radio shack sell wall mounted speaker controls,but 5 watt max.
the best thing is to run 2 amplifiers.one for in ,2 for out
speaker a and b on the amp parallel the speakers.
if you run 2 sets of 4ohm speakers,the amplifier load will be 2 ohms,and overheat the amp.4 8 ohm speakers,gives a 4 ohm load

When i turn up the stero the power turns off and the red standby light flashes till i turn it back on


Firstly i would disconnect all speakers and turn amp up if still does it then there is an overload in amplifier anbd needs to be repaired..

If not then connect speaker 1 at a time and try amp volume again,you could also get a multimeter and check across speaker terminals on boxes for different resistance readings..

Can you run 200watt 6ohm speakers on the RX-V490


Hi I have just read the specs on about your Yamaha system and you cant run 6 ohm speakers to your amp. You have to impedance match the speakers and the amp otherwise the speakers will "blow". So you need some 8 ohm speakers, the wattage of the speakers doesn't particularly matter as long as they are not too weak or too powerful becasue the amp will drive the speakers no matter what but if the speakers are of a low wattage then the amp could blow the speakers if it is turned up too loud. The specs of your amp are given in the link below.

Rotel PReamp, Can I directly Connect my powered speakers to the output


Hi,

Based on your post, the pre-amp is doing its job. What might be the mismatch would be the powered speaker system plugged into the output of the Rotel. Depending on what the "powered speaker system" is, it might be that it is a low impedance such as those used in computers whereas the Rotel requires high impedance to be connected to its output. What could be tried is to connect a regular amp or receiver to the Rotel.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
