Work fine, but needed at input with1:10 regulated resistors. Output have 0,1V—0,15V DC .
Als beschrijving, enorm snel aangekomen. Amper 2 weken. Perfect verpakt. Zal ze later testen.
Good value for money. Range 20-20000hz Crossover frequency 400/500hz depending on speaker setup(6 ohm= 450hz) see pics for spectrum analyzer output. Low and high frequencies showed every horizontal bar is 6db octaves freq readout on bottom bar.
