Mega Bass Circuit using 4558

The megabass circuit is a modified Baxandall tone control with no bass cut and no treble control. It boosts frequencies from about 30Hz to 160Hz can boost by 14dB.

Mega Bass Circuit using 4558

Note:
  • The input capacitor can be replaced with a .01uf cap if you wish.
  • The 10pf capacitor is optional and will start rolling off everything over 15kHz. 5pf will double this to 31kHz.
  • The tone control requires a low impedence input. If you already have a low impedence input, the input buffer can be removed. However, the output is inverted.
  • The opamp is not critical. A 4558 would be just fine.
  • I do not show the parts for the +4.5 reference. Here is the +4.5 voltage divider I used.
  • IC A4558 Pinning IC A4558 Pinning
IC 4558 is a monolithic Integrated Circuit designed for dual operational amplifier.
  • Absolute maximum ratings of A4558 Ap-amp
  • Supply voltage VCC 20 or ±10 V
  • Differential input voltage VIND 20 V
  • Input voltage VIN ±10 V
  • Power Dissipation PD 300 mW
  • Operating temperature Topr -45 ~ +85 °C
  • Storage temperature Tstg -55 ~ +150 °C
