Loudness Control. • Jeff Phillips (c) 2019 - Enjoy! • Rather than a drawing... • From standard FLAT to entirely more WARMTH to your senses... • Imagine a disc lying on its side, then looks like a broad elipse. • With a loudness control you see Bass Mid Treble waves. • That surface visual changes as you adjust knob. • Variable control brings about other levels. • This circuit is set to a basic range. • Varying freq' ranges for sound. • Coming out your speakers. • Via pre amplifier inputs. • Entirely more pleasant. • Some commercial units have a range of 50Hz to 10kHz • At +10dB Flat around dial to +5 dB Loudness. • That's quite a range, see your comp' eq'. • (If only politicians could think that broadly and kindly!) • UPDATE: • After looking for my original copy of this circuit - Top left at the first 15kohm quarter watt resistor, there should be a 0.0033uF(50volt) ceramic capacitor in parallel with it. That is, one leg on each side of that resistor to complete the circuit properly. Note the zeros value. My apologies! • Like a preset equalizer circuit. • Definately worth the effort and warms your sound up ! ! ! • Quarter watt resistors. • Capacitors are ceramic type. • Put between player and amplifier. • Mono, make two for stereo. • Use shielded cables. • Mount in a box. • Tip: Use RCA plugs but keep a couple of quarterinch adapter plugs with it for guitar then you can use it for both. • Finaly found a link, see copy of image that we followed back in the day • https://makingcircuits.com/blog/headp... • The Home Utility Project and HTA Program examples. • http://jeffphillips2000.tripod.com • / thehomeutilityprojec • Your comments welcome below...
