This 10 Band Graphic Equalizer Circuit a single chip, IC TL074 to achieve a 5-band graphic equalizer for use in systems of high fidelity audio. The 5-band graphic equalizer is true for radio-cassette player and car stereos. This unit features: low distortion, low noise, wide operating voltage range (3.5 V to 16V), low consumption (5 mA), Wide Dynamic Range (SD = 2.1Vrms/VCC = 8V) and built an amplifier input and output buffer.
The TL074 is a five-point graphic equalizer that has integrated all the functions necessary for a cochlear implant. The IC is the system of five sounds and control input and an output buffer amplifier. The following PDF contains detailed information on the wiring diagram for the 5-band graphic equalizer with a single IC / chip (BA3812L). The circuit shown in the table of works about five frequency bands: 100 Hz, 300 Hz, 1 kHz, 3 kHz, 10 kHz.
