14+ 3 Band Equalizer Circuit Diagram. The ic used here is lf 351 which is a wide bandwidth single jfet operational amplifier. It is designed around the lm833 opamp from national.
It is designed around the lm833 opamp from national semiconductors. The circuit can be easily converted to a 5 band graphic equalizer by simply eliminating 5 stages from the shown design. In the circuit the supply is ± 15v, but can be also supplied with alone supply + 9 until + 30v, it is enough it is.
This 3 band equalizer circuit is an active filter network for bass, mid and high audio ranges.
14+ 3 Band Equalizer Circuit Diagram. Eighteen volt power supply for more amplifier headroom. Equalizer the s5a1901h02 provides the graphic. It is designed around the lm833 opamp from national semiconductors. Simple audio equalizer circuit constructed by using famous 5 band graphic equalizer ic la3600, this is a monolithic linear ic from sanyo.
