Circuit of graphic equalizer of 7 bands using it integrated la3607 of Sanyo

The integrated circuit LA3607 enables the configuration of a 7-band graphic equalizer for a single audio channel by incorporating additional capacitors and variable resistors. The cutoff frequency can be modified using variable resistors. It demonstrates high stability when handling capacitive loads. To accommodate more channels, additional units of the circuit can be implemented as needed.

The LA3607 is a versatile integrated circuit designed for audio processing applications, specifically for creating graphic equalizers. This circuit allows for the manipulation of audio signals across seven distinct frequency bands, enabling precise control over the tonal quality of the audio output. The use of variable resistors (potentiometers) in conjunction with capacitors provides the user with the ability to fine-tune the cutoff frequencies for each band, allowing for a customized audio experience tailored to specific listening environments or personal preferences.

The high stability of the LA3607 when interfacing with capacitive loads is a significant advantage, as it ensures consistent performance even when the output is connected to varying types of speakers or other audio devices. This characteristic is crucial for maintaining audio fidelity and preventing distortion, particularly in professional audio applications where sound quality is paramount.

For applications requiring multiple channels, the LA3607 can be cascaded by adding additional units, each configured similarly to the first. This modular approach allows for scalability in audio systems, accommodating various setups from simple home audio systems to complex multi-channel sound reinforcement systems. Each additional unit can be independently adjusted, providing comprehensive control over the audio output across all channels.

In summary, the LA3607 integrated circuit is an efficient solution for creating a 7-band graphic equalizer, characterized by its adjustable frequency settings, stability with capacitive loads, and scalability for multi-channel applications.The circuit integrated la3607 allows to just set up a graphic equalizer of 7 bands for a channel adding some capacitors and variable resistors to the circuit. The cut frequency can be adjusted using variable resistors. It possesses high stability for loads capacitive. To be necessary of more channels is to set up how many units they are only neces sary. 🔗 External reference
