What wattage does this iMac’s speakers use from the motherboard?




I’m converting iMac Late 2009 speakers into regular headphone jack speakers by soliciting the cables and I connected them right where there is no distortion and they sound good but the volume is low and doesn’t go higher. I think this is because there is nothing powering the amplifier inside the speaker so I need to connect a power source but I need to know what is the wattage these speakers use?
Teddy if you like those speakers you do not want them connected as previously described by you. The iMac where those speakers are coming from use a Woofer and a Tweeter amplifier. Your speaker separates the tweeter and the woofer in the plastic case. Each set of white/black cables is for the separate speaker. Connected one set of black and white to power will most certainly put an end to either one of those. If you are wanting to use the amp listed in the preceding answer, connect the two white and the two black from each speaker housing to either L or R. L- (WhiteX2) L+(BlackX2) and same for the right.


Here are the values for the amplifiers


TWEETER SPEAKER AMPLIFIER


AMP VOUT = 7.355VRMS


GAIN = -4.8(20K/17.4K)


MAX9736B APN:353S2042


POUT = 6.76 W INTO 8 OHMS @ 1% THD+N


WOOFER SPEAKER AMPLIFIER


AMP VOUT = 7.355VRMS


GAIN = -4.8(20K/17.4K)


POUT = 6.76 W INTO 8 OHMS @ 1% THD+N


RIN = 17.4 OHMS


FC = 19.5 HZ
motherboard - optical s/pdif out port(s) at back panel
dvd player - appears to have no audio input
speakers - do they have an s/pdif input?

so it appears you don't have the right things to connect to the other right things.

thanks for prompt reply,
ok leave the dvd aside and tell me that can't my mother board act as an amplifier or receiver as my mother board is new and it has the best inbuilt realtek® alc892 8-channel sound card?
one more thing tell me a best solution to make 5.1 surround system with these speakers.

the motherboard audio does not have an amplifier in it to drive speakers, the speakers have the amp in them. and that motherboard is capable of 5.1 sound, it's an 8-channel sound card in fact. what exactly are you having issues with? read the manual to the motherboard and the speakers, between those it should tell you what you need to do. those cables will work but you don't really need them as you only have to get to where the speaker wire comes out of the wall. just cut a pair of rca cables in half. there will be a center wire that connects to the positive and the shield, that wraps around the insulated center wire, is the negative. 
the only potential problem is that you may not have enough power to drive the rears loud enough. you need to add an external speaker selector and connect it to the front speaker connection on the receiver. set the receiver to stereo.
when you play them all together one pair may be too loud so you can connect an external speaker level volume control to the pair that are too loud. that can go in the remote location if needed. you can also get the speaker selector with volume 
controls built in.

You can get the "power cord" for your Logitech MM50 from [here](http://www.buylogitech.com/store/logius/en_US/DisplayCategoryProductListPage/categoryID.11200700). (http://www.buylogitech.com/store/logius/en\_US/DisplayCategoryProductListPage/categoryID.11200700)  
  
Hope this be of help/ Pls post back how things turned up or should you need additional information.  
  
Good luck and kind regards. right: that's because your play:1 speakers do not support airplay. the support article below may help.

there might be not enough power for your usb devices after you draw some with your ffc camera.

what are you powering the board with? try dc jack with a beefier power supply.

cheers,

olex hi everyone, just to close this topic, i could get a proper power supply and in fact it was the problem..

thaks everyone for your time and help ! there is no update from you for a period, assuming this is not an issue any more.

hence we are closing this topic. if need further support, please open a new one.

thanks

hi,

is the default audio setting from hdmi not able to achieve what you want? If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all.  

OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time.  
If the battery drops to an unacceptable charge level then the battery needs to be replaced Unless the walls are perfectly flat around the switches (most walls aren't) and the metal back boxes are deep enough to accommodate the switch properly, they will never be a good fit and will sit awkwardly with one or more edges sitting slightly proud.

When you see these low profile flat plate switches in the shops they are always mounted on nice flat pieces of wood or plastic so look great. Once fitted in the home, the reality is somewhat different!
