Using an external transistor ten-band equalizer
The ten-band equalizer circuit described employs the TA7796 integrated circuit, which is designed for audio signal processing and is capable of providing adjustable gain across multiple frequency bands. The use of five external transistors enhances the circuit's ability to amplify and filter audio signals, allowing for precise control over the tonal qualities of the sound output.
In this configuration, the lowest center frequency of 100 Hz targets the bass frequencies, ensuring that low-end sounds are effectively managed. The highest center frequency of 16 kHz addresses the treble range, allowing for clarity and brightness in audio playback. The selection of a crystal tube in conjunction with the 9014 transistor is notable for its role in maintaining signal integrity and minimizing distortion within the equalizer circuit.
The p-value of 500 indicates the gain factor that is applied within the circuit, influencing the overall output level and responsiveness of the equalizer. This value is crucial for achieving the desired balance between the various frequency bands and ensuring that the audio output is tailored to the specific requirements of the listening environment.
Overall, this ten-band equalizer circuit exemplifies a sophisticated approach to audio signal processing, combining the capabilities of the TA7796 with external components to deliver a versatile and high-performance audio equalization solution.Another example of application is extended. It uses TA7796 and five external transistor to form a ten -band equalizer circuit, the lowest center frequency of the equalizer for the 1001-L :, highest center frequency circuit 16kffio crystal tube using 9014 and other, p value should be 500.
