LM4558 IC Subwoofer Bass Booster Circuit Diagram:


LM4558 IC is the Dual Operational Amplifier and mainly used for Bass booster for the subwoofer in audio systems. LM4558 IC having two general-purpose Op-amp and which is from ‘LMxx’ family. This LM4558 IC-based circuit only for Bass from this circuit extra bass is increased and also this circuit gives clear bass without any disturbances. Who wants to required extra bass then you can use this circuit. But those can remember this circuit not given treble and it only gives the bass Output for a speaker or woofer.

LM4558 IC Subwoofer Bass Booster Circuit Diagram

From the above LM4558 subwoofer bass amplifier the Input or Output should be connected to volume control for control the gain of the Operational amplifier for better bass without any disturbance or noise. In this prefix, LM stands for linear monolithic and referring to the dual analog components integrated into a single piece of silicon. This LM4558 chip has short circuit protection and internal frequency compensation and provides stability without using any external components.

Who wants to make Any 2.1 or 5.1 Sound System Then This Circuit Can be used For your Bass Speaker For Extra Bass booster Effect and you should use only for the subwoofer for bass, remaining channels are normal input has to give.
