5-Band Graphic Equalizer with LA3600

This complete high quality, low noise 5-BAND GRAPHIC EQUALIZER circuit is based around Monolithic Linear integrated circuit LA3600 manufactured by SANYO. This circuit is very easy to build and has good Quality. You can use it with Portable component stereos, tape-recorders, radio-cassette recorders, car stereos etc... More: It is On-chip one operational amplifier. 5-band graphic equalizer for one channel can be formed easily by externally connecting capacitors and variable resistors which fix fo (resonance frequency). Series connection of two LA3600?s makes multiband (6 to 10 bands) available. It is Highly stable to capacitive load. Maximum supply voltage VCC max 20V must not be exceeded. The operating voltage is in the range of 5 to 15V. Application of power with the pin-to-pin spaces shorted causes breakdown or deterioration of the IC to occur. When mounting the IC on the board or applying power, make sure that the pin-to-pin spaces are not shorted with solder, etc.

The 5-band graphic equalizer circuit utilizing the LA3600 integrated circuit is designed to enhance audio performance by allowing users to adjust frequency response across five distinct bands. This circuit is particularly suitable for portable audio devices, including component stereos, tape recorders, radio-cassette recorders, and car stereos, making it versatile for various audio applications.

The LA3600 IC integrates a single operational amplifier, which simplifies the design and reduces component count. The equalizer can be configured by connecting external capacitors and variable resistors that define the resonance frequencies for each band. This flexibility enables precise tuning of the audio signal, allowing users to boost or cut specific frequency ranges according to their preferences.

For applications requiring more than five bands, the circuit can be expanded by connecting two LA3600 ICs in series, facilitating the creation of a multiband equalizer with six to ten bands. This modular approach not only enhances functionality but also maintains the overall stability and performance of the equalizer.

The circuit exhibits high stability when driving capacitive loads, ensuring consistent audio quality without distortion. The operational voltage range of the LA3600 is between 5V and 15V, with a maximum supply voltage of 20V. It is critical to adhere to these voltage specifications to prevent damage to the IC. Care should be taken during assembly to avoid unintentional short circuits between pins, which could lead to breakdown or degradation of the integrated circuit. Proper mounting techniques and careful inspection for solder bridges are essential to ensure reliable operation of the equalizer circuit.This complete high quality, low noise 5-BAND GRAPHIC EQUALIZER circuit is based around Monolithic Linear integrated circuit LA3600 manufactured by SANYO.
