TDA 7294 Bridge Amp maximum Power output

sunny · 19th May 2011, 06:53 PM

I have succesfully completed building TDA 7294 Bridge Amp using +/-35 volts. As per the data sheet it is mentioned that power output with 8 ohms speaker is 150 watts.Is it RMS power or maximum power output and what is the PMPO output of TDA 7294 bridge AMP?

Thanks,
Sunny.

PMPO means nothing. It is only used by cheap & crappy "audio"-brands.

150 watts peak or 75 watts RMS.

I would agree with vigier there pmpo..is a company's way of trying to make some low end/cheap units 'sound' better so people will buy them....always go for the true rms power instead..

@sunny..place a meter on the o/p of your bridged unit and read the ac o/p voltage at full power and use ohms law to get your answer, oh and don't bridge your amp at 4 ohms or it will fail...
