This is a20 watts audio amplifieris suppliedwith a voltage14.4volts,givinga total power of20wattsinto twodifferent channels, each of whichis connectedto thetweeteranda woofer. This amplifier isthereforeequipped with an active CROSSOVERfilterwithacrossoverfrequencyof 2KHz. Eachloudspeakermust supporta power of 10wattsandhaveanimpedanceof 4 ohms. The supply voltagecan bebetween12and up to 15volts. This two way amplifiercan also bebeneficially usedas aBOOSTERfor2 wayradio.In this case, it is necessaryto place a3.3Kohmresistorbetween theoutputof theradioandthe amplifierinput(seediagram). Toavoid unpleasantdistortion,we mustavoidto applyinputsignalsgreater than 50 mV.
