Product Description
The LM324E SMD Bass Treble Preamplifier Board is a professional-grade audio processing module designed to give you total control over your sound signature. Utilizing the high-performance LM324 operational amplifier in an SMD configuration, this board provides active tone filtering with minimal noise and distortion. At Robogears, we recommend this pre-amp as a bridge between your audio source (like a Bluetooth module) and your power amplifier. It allows you to boost the low-end frequencies for deep bass and sharpen the high-end for crisp treble, all while managing the master volume. Its wide 12V-24V operating range makes it perfectly compatible with standard 12V car audio systems or 24V industrial power supplies.
Detailed Key Features
Active Tone Control System: Unlike passive tone circuits that "cut" frequencies, this active pre-amp can boost signals, ensuring your audio remains powerful and dynamic.
SMD Precision Components: The surface-mount design reduces the PCB footprint and minimizes parasitic capacitance, resulting in a cleaner, more stable audio signal.
Three-Way Adjustment: Features dedicated potentiometers for Bass, Treble, and Master Volume, providing a customized listening experience.
Wide Voltage Versatility: Engineered to work flawlessly across a broad DC spectrum, making it ideal for both DIY home theater and automotive audio upgrades.
Low Noise Interference: The LM324 chip is selected for its reliable performance and low power consumption, ensuring that no "hiss" is added to your audio path.
