Integrate Amplifier Audio amplifier based on TDA7294 on 4 ohm speaker?
I have an audio amplifier based on TDA7294 integrated circuit. It is set to drive a load of 8ohm (speakers). I have a 4ohm subwoofer. Can i connect the 4ohm woofer to it? I looked at the specs ( http://www.datasheetcatalog.org/datasheet/SGSThomsonMicroelectronics/mXqwvzw.pdf ) and it says it can drive both 4ohm and 8ohm loads. The supply voltage must be set for 8ohms i guess. Will a 4ohm woofer work on this?
Help will be much apreciated. Thank you.
it should be fine without modification. the supply voltage does not need to change based on the output load. the distortion will go up a bit but it is frequency dependent and since this is a subwoofer it should not be detectable.
