Audio Equalizer Tone Control Circuit with Bass, Treble and MID Frequency Control using Op-Amp

Audio Equalizer / Tone Control Circuit with Bass, Treble and MID Frequency Control using Op-Amp

Tone control or Active equalizer circuit especially bass, treble, and MID control based Equalizer is an important circuit in audio amplifier design. Generally, three-stage active Equalizer filters require three control bass, treble, and MID. The bass control allows the low frequency to pass but blocks high frequency and the treble control allows the high frequency to pass …

Friwo LED drivers will light up your LEDs as much as you just want

Friwo LED drivers will light up your LEDs as much as you just want

LT series LED drivers with 10-100W power represent a complete solution with wide possibilities of control. Exceptionally narrow and slim design, remained even at high-power versions, provides a high flexibility of use. Power supplies for LED lighting (so called drivers) are available from many producers, in a various qualitative level. Why to decide just for …
