10 band equalizer

Posted on Feb 6, 2014

This circuit uses a single chip, IC TL074 for achieving a 5-band graphic equalizer for use in Hi-fi audio systems. The 5-band graphic equalizer is true for radio-cassette player, and car stereos. This unit features: low distortion and low noise, wide range of operating power voltage (3. 5V to 16V), low-power (5 mA), Wide Dynamic Range (DE = 2. 1Vrms

/VCC = 8V) and built an amplifier input and output buffer. The TL074 is a five-point graphic equalizer, which has integrated all the functions necessary for a CI. The IC is the system of five sounds and control input and an output buffer amplifier. The PDF below 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 works around the five frequency bands: 100Hz, 300Hz, 1kHz, 3kHz, 10kHz.
