XH-A901 NE5532 Stereo Tone Board Pre-Amplifier with Bass, Treble & Volume Control
The XH-A901 NE5532 Stereo Tone Board Pre-Amplifier is a high-performance audio preamp module designed to improve sound quality before the power amplifier stage. Built around dual NE5532 low-noise operational amplifiers, it delivers clean, detailed stereo audio with minimal distortion and an excellent signal-to-noise ratio.
Featuring independent Bass, Treble, and Volume controls, the XH-A901 allows precise sound customization to match your speakers and listening preferences. It is ideal for DIY amplifier builds, Bluetooth speaker systems, home theatre projects, multimedia speakers, and Class-D/Class-AB amplifier modules.
Available in two power input variants, the board supports either 12–24V DC operation or 12–15V AC input. The AC version includes an onboard bridge rectifier for direct transformer connection, while the DC version operates from regulated DC power supplies or batteries.
Compact, reliable, and easy to integrate, the XH-A901 is an excellent choice for audio enthusiasts, makers, repair technicians, and custom amplifier projects.
