i have a car cassete player with an output of 20w rms.I`d like to put the output of the player to a audio amplifier but the amplifie has no hight audio power input.So i need an "reductor" of audio power.Anyone has a schematic or a link to a site?
the variant with a resistor sucks because the signal is distorsionated
Resistors should work, but you will have to use a value near the speaker resistance ~ 8 Ohm to prevent distortion. Try to use a divider with 8.2 Ohms to 0.33 Ohms.
my needs are more..... id like to make some kind of audio premplifier with an equalizer that have an inside audio power reduction.thats what i need.And this preamplifier woud drive an audio amplifier.
try with ina105. its a differential Amplifier. the Output you must design ~1 Vss and output resistance ~47Kohm. (with resistor divider it doesnt work.) :lol:
