Can you tell me model number of the speakers who compatible with my sony str-333s receiver.


HI,
Sony STR 333S have an out put power of 25W into 8 Ohms speakers. You can use any bookshelf speakers with an impedence of 8 Ohms.
Ok

Hi, It may not be a wiring problem, or a heat issue, but it should be related to what is at the other ends of the speaker wire. I, of course, don't really know what is happening with your receivers. I guessing.
My only rational guess besides the receivers having been defective is this.

So here the theory part:
An amplifier is designed to operate with a certain amount of 'LOAD" on it's speaker outputs.
It will say something, in the manual and perhaps on the back of the unit itself at the speaker terminals
"4-8 Ohms (a measure of resistance, the load itself) 4-16 Ohms, etc.
So what happens when you wire in parallel Two 8 ohm speaker systems together. You get 4 ohms.
Not a problem.
What happens if you wire four 8 ohm speakers together, you get a load of 2 Ohms. This level of resistance if very low for a receiver and it will go into a protection mode. If you were able to run it without protection, the output transistors would cook internally. The Receiver itself wouldn't necessarily get hot. But that would happen.
If you put four 4 ohm speakers together. The amplifier would see 1 ohm resistance. That is almost a short circuit.
So if you happen to be running multiple speakers together. Check this point out.
Hope this helps,
Best,
Mark

Power out rms- 4 o 8 homs?


I can see why you're asking for help on this. It almost seem this unit has been 'disappeared' as far as online information is concerned. Even Sony has nothing on it.

I founs some articles and For Sale posts:

http://toronto.kijiji.ca/c-buy-and-sell-electronics-Sony-STR-4800SD-Stereo-Receiver-135-OBO-W0QQAdIdZ243602516
"Sony's STR-4800SD receiver was extensively, and positively, reviewed in Stereo magazine's Fall '77 issue. In their introduction, they found the 4800SD bettered its published f.m. sensitivity specs "by a wide margin...it has exceptionally smooth frequency response, very low distortion(especially in the midband), and excellent quieting. No exotic claims are made for the power amp section, either (35 watts/channel,15.4 dBw at 0.2% THD). But our tests indicate much more capability than that, and a distortion of only one-tenth that spec."

The power consumption figure shown in a photo below says "145W", which would be consistent with a 35 watt amplifier.

Ive got a str-dg520 reciever and have a loud hum coming from all speakers have tryed removing all wires then putting back in but still happens


Try replacing the big Electrolytic Capacitors in the power supply section. When they go the let the 50/60HZ hum into the audio from the mains supply.

Can I install 4 6 ohms speakers on an 8 ohms a/v receiver? receiver Sony STD HD 800 speaker system: Jamo S413 HC S5 Home theatre system,


Best Answer - Chosen by Voters An ohm is a unit of electrical resistance. You can think of it as your speaker will impede or pull 8 ohms from the amplifier that is powering it.

8 ohms is less resistance than 4ohms. So a 4 ohm speaker would require more juice than your 8 ohm.

If this is the only speaker, then that's all the resistance you have to worry about handling. If you had two of these speakers wired in parallel, then the total impedence would be up to be 4 ohms, because each speaker actually reduces the resistance in the circuit...so 8 ohms + 8 ohms = 4 ohms.

You use this information to make sure your amplifier is powerful enough for the speakers. If the speakers have too much resistance, they'll fry your amp.

Here's a good sentence to help explain, but I recommend reading the article I linked in sources...

"An amplifier designed to put out 100 watts into 8 ohms will put out 200 watts into 4 ohms. Two 8 ohms speakers wired in parallel (4 ohms total) would cause the amplifer to produce 200 watts." Source(s): http://www.marktaw.com/recording/Electro…

Sony STR-DB940 Receiver Speaker Impedance Question


Whats the rating on the Plasma? How many watts at 4 ohms? If the plasma is rated 100 w at 8 ohm... hanging a 3.4 ohm load would put a lot of strain on the plasma's output amp. At 3.4 ohm the amp would be trying to delive close to 200 watts at full power. But it depends on how hot you normally run the volumn. Remember an amplifier output is AC volts. 1 ohm of resistance is close to a dead short. The amplifier would have to work its *** off to supply that type of power and would probably burn the output op-amps. If the outputs burn & it pumps any DC current through the speaker wire..the speakers would be toast...if not catch on fire. Try to keep the speaker load at or very cloe to the plasma's output load rating. Also if the plasma doesn't state it will handle loads down to 2 ohms...It probably won't.
