Want to use my current speakers with a new surround sound system. Current system is 5.1 channels, rated at 100w per channel @ 8. Ohms. New System is rated 145watts, 5.2 channels at 6 Ohms. Will b ok?


Hi Ronald.
8 Ohm speakers will work just fine as replacements for the
6 ohm speakers. When fitting speakers you need to consider
The power handling capability. The impedance and the frequencies
involved. Power handling is expressed in wattage ie 100W.
Unfortunately this can be expressed in rms, max or peak music. The rms value (root mean square) is the only really relevant figure as this is the continuose handling power at 1 KHz. The impedance
is the resistance that the amp sees but is not a dc resistance and
varies with frequency. The lower the impedance the more power
will be drawn from the amp. In the event of a short circuit across
the speaker the amp will try to deliver infinite power into an infinitly
small load in an infinitesimal amount of time and will self destruct.
Using an 8 Ohm speaker draws less power than a 6 Ohm speaker.
Connecting speakers in parallel; results in the impedance beingreduced. For example two 8 Ohm speakers in parallel will result
in a 4 Ohm impedance load but in series will be 16 Ohms.
Incidentally the the .1 (5.1) is the sub woofer which only has
to handle the bass frequencies, a small percentage of the
amplifiers overall frequency response..
Connect your speakers and then power up the amp last
after double checking there are no shorts on the speaker
cables.
All the very best from Vintie.

Amp keep's sating overload


Have you tried disconnecting all the speakers and inputs and turn it on?
If it still shuts off you have an internal problem, if it stays on, connect one item at a time until it shuts off and that is the problem.

How to equalize extra speakers?


The only thing you can do to equalize those speakers. Make sure that you have them in faze. + to + and - to - and left to left and right to right. Make sure that your speaker can handle the ohms. (the same ohms) for example If your amp is rated to handle 8 ohms then your speakers should have 8 ohms. The speaker wattage should also be abit more than what your amp can produce. Distortion is your worst killer of speakers.

My yamaha rxv595a keeps on shutting itself off when im watching movies as soon that it gets loud it shuts off but its not even that loud how do i fix this problem i tried the ohms switch in the back and it...


That is a safety switch in most receivers. When something gets too loud it cannot give the load off to the speakers and shuts off to protect itself. This can mean that the receivers getting old, or that you might need to split the job. You might need an stereo amplifier to split the job. Check the cables and speakers. Recievers can only give so much to so many speakers at so much sound. That is what the whatts are for. The more whatts the better, the lesser whatts, the lesser speakers its going to be able to handle at high volumes.

Receiver shuts off at higher volumes


The receiver may be too under powered for your speakers or the speaker ohm's may not be matched for your amp.

The reason it is shutting off is likely because the amp is becoming overloaded. At lower volumes the amp can handle the load of the speakers, but at higher volumes the power supply of the amp can't keep up with the power demand the speakers are pulling.

If you were previously able to turn the reciever high without turning off, then there is likley something wrong with the amp or possibly a blown speaker.

Try measuring the resistance of the speakers if you have access to a multimeter. They should normally read 8 ohms for home speakers, but some common home speaker impedances in order from (I'm assuming) most common to least common are are 8, 4, 2(bose), and sometimes 10 or 12 ohms. The lower the number of ohms, the more power the amp will need to put to the speakers and the more chance you could be overloading your amp.

Speaker compatibility ( Just got this new reciever with 120 volts power requirement of the receiver, but in the philippines voltage standard supply is 220. can i use 110 voltage supply instead? and I dnt...


The most likely answer is no. Unless the power transformer is of the multi tap type and has a voltage selector window on the back panel... Most speakers today have an impedance of 8 ohms. The impedance is all you need to worry about when matching speakers. You can fit 8 ohm speakers to a 4 ohm system, but you cannot fit 4 ohm speakers to an 8 ohm system. It would overload your oputput stages and cause them to fail. It's best to match 4 ohm with 4 ohm, 8 ohm with 8 ohms.etc.

Wireing two dual 4 ohm kicker cvr 15s on a memphis pr1000 at a 1 ohm load. I trying to get these kickers to hit harder. Do I need a bigger amp or what?


CVR series do not have large power handling capabilities.
Your subs will melt before the amplifier is used to its full potential.
If the subs arent in a ported enclosure - do that.
They both handle 500w rms - so the pr1000 is perfect.
bass response is all in the enclosure!

Reciever shuts off


Hi there

May I ask how many watts can your reciever handle ? And how many watts does your speakers need in order to be powered up (input). The two speakers you have installed might be too powerful for your reciever to handle. You might have to down grade to less powered speakers. All in all you have an excellent product there good choice...

Speakeres killer


Are you paying attention to the power rating of your speakers? Your receiver has a high power capability and would be quite capable of destroying speakers with inadequate power handling capabilities.

By the way, the Tivoli was a great place to be in 1963 for a young guy!
Hope it still is . . .
