LA3600 5 Band Equalizer Circuit

One type of tone regulator is the audio graphic equalizer, which can be categorized into two types: the audio graphic equalizer bar and the parametric equalizer. This article focuses on the bar type, specifically a 5-channel equalizer utilizing the LA3600 integrated circuit (IC). The LA3600 is a dedicated single-chip solution designed for a 5-channel audio graphic equalizer, simplifying the equalizer circuit. The audio graphic equalizer circuit with the LA3600 can control audio frequencies ranging from 108 Hz to 10.8 kHz. The specific frequencies managed by this equalizer are 108 Hz, 343 Hz, 1.08 kHz, 3.43 kHz, and 10.8 kHz. The center frequencies for each channel can be adjusted by changing the values of two capacitors associated with each channel.

The audio graphic equalizer using the LA3600 IC is designed to enhance audio playback by allowing users to adjust the amplitude of specific frequency bands. The LA3600 integrates all necessary components into a single chip, making it an efficient choice for audio applications. Each of the five channels corresponds to a specific frequency band, which is predetermined by the circuit design and the values of the capacitors connected to the input of each channel.

The frequency bands targeted by the equalizer are strategically selected to cover the critical range of human hearing, allowing for precise control over bass, midrange, and treble sounds. The lowest frequency of 108 Hz is typically associated with bass sounds, while the highest frequency of 10.8 kHz corresponds to treble sounds. The intermediate frequencies, including 343 Hz, 1.08 kHz, and 3.43 kHz, address the midrange spectrum, which is crucial for vocal clarity and instrument definition.

Adjustments to the center frequencies can be made by altering the capacitance values of the two capacitors connected to each channel. This flexibility allows for customization based on user preference or specific audio requirements. The circuit diagram for the 5-channel audio graphic equalizer with the LA3600 will typically illustrate the connections between the IC, the input audio signal, the output to the amplifier, and the capacitors that set the frequency response for each channel.

In summary, the audio graphic equalizer using the LA3600 provides a user-friendly approach to audio manipulation, allowing for tailored sound experiences across various audio playback scenarios. Its design simplifies implementation while offering sufficient control over key audio frequencies, making it a valuable component in audio engineering and sound system design.One type of regulator of tone / tone controls are the Audio Graphic Equalizer. Audio Graphic Equalizer have 2 kinds in my opinion. Namely Audio Graphic Equalizer Bar and the type of parametric type is often called parametric equalizer. Audio Graphic Equalizer In the article this is the type of bar with 5 channels using IC LA3600. IC LA3600 is a single chip "Audio Graphic Equalizer 5 channel" that is designed specifically for the equalizer five channels. Because IC LA3600 is a special design of the equalizer circuit to make this a simple equalizer. Figure series of Audio Graphic Equalizer 5 channels with IC LA3600 as follows. Audio Graphic Equalizer circuit with IC LA3600 above can control the audio frequencies from 108 Hz to 10. 8 KHz. Audio frequency which is controlled by this equalizer was 108 HZ, 343 Hz, 1. 08 KHz, 3. 43 KHz and 10. 8 KHz. The frequency of that frequency is set based on the value of 2 pieces of capacitors in each chanelnya.

So for instance want to change the center frequency of each channel value of 2 pieces of the capacitor can be changed as desired. 🔗 External reference
