No description available.


This circuit enables sound system to operate efficiently, which does not require any frequency compensation circuit. It features no latch up when input common mode range exceeded. It has low power and short circuit protected component that it could operate with ease of power supply problem.

The design is comprised of LM1458 dual operational amplifiers that manages the amplification of signal from input to output. The RC coupled circuit amplifies low frequency signal while the capacitor at the output side helps in stabilizing the output signal. The variable resistors are used to control gain of both side.

This basic surround sound system is suitable for improving the sound quality of common speakers. It is simple that a regular student could build and developed the design itself. It is easily integrated even on portable devices.
