Electronics Help Care Amplifier circuit diagram
Only the bass circuit diagram for the bass amplifier:
This is the only bass circuit diagram for the bass amplifier. It’s the best low-pass filter circuit diagram to make a bass amplifier. It’s a stereo circuit board. left side and right side. This circuit runs with a minimum 12-0-12 voltage to a maximum 18-0-18 voltage. positive, negative, and ground voltage. only DC voltage.
The LF347N is a low-cost, high-speed Quad JFET-input operational amplifier (op-amp). It integrates four independent op-amps into a single monolithic 14-pin dual in-line package (DIP-14). It is widely used in high-speed integrators, digital-to-analog (D/A) converters, and sample-and-hold circuits.
5.1 Channel Hi-Fi Amplifier circuit diagram:
This is the 5.1 Channel Hi-Fi Amplifier circuit diagram made in the USA. This circuit is designed for a home theater system, featuring two front speakers, two rear speakers, one center speaker, and one subwoofer speaker. If we use a Dolby input sound card, we can get Dolby surround output. for the surround speaker, LM1875. And for the subwoofer, a TDA7294 was used.
The LF347N follows the industry-standard DIP-14 pinout for quad op-amps. It is pin-compatible with the standard LM148 and can often replace or upgrade existing LM124 or TL074 designs where higher speed or JFET performance is required.
In audio electronics for 2026, a bass circuit primarily refers to a system designed to process or amplify low-frequency audio signals, typically ranging from 20 Hz to 250 Hz. These circuits are essential for subwoofers, electric bass guitars, and high-fidelity sound systems.
how to make 2.1 home theater:
Normally, we use this circuit in a computer soundbox. Here, the TDA2030 IC is used. One is for the bass speaker. Another 2 is for a surround speaker, one for the right speaker, and another for the left speaker. for this circuit need 12-0-12 to 18-0-18 voltage. here used, 4558D is used to make a low-pass filter.
