Adjustable Bass Filter Circuit

Of a power amp bass amp filter circuit can be used in different times, in addition + – 60 + symmetrical voltage – 15 volts regulator circuit for limiting transistor has The frequency of the filter cut-off regulated na is a stereo potentiometer P1. For acoustic applications, the filter does not it must be perfect

Quality Headphone Amplifier with TL072 Op Amp

TL072 Headphone Amplifier circuit based on the output of Op Amp and bc328 bc338 transistors simple and low cost circuitry is powered by the supply voltage + – 15 volts symmetrical this project as a general-purpose headphone amplifier, as long as it is fed with “line level” signals – such as the output of a

Speaker Protection and Fan Control Circuit

This loudspeaker and fan controller has been specifically designed to suit the Ultra-LD 100W per channel amplifier described in the March and May 2000 issues. Not only does it provide muting at switch-on and switch-off to prevent any thumps from the loudspeakers, it also protects the loudspeakers against catastrophic failure in the amplifier. In addition,
