## Description

Stereo audio preamplifier for signal enhancement in hi-fi systems or amplifiers, based on 2 NE5532 operational amplifiers for clean and detailed sound. Offers full tone and level adjustment through volume, treble, middle and bass, operates at 12-24VDC, has low noise and very low distortion for faithful reproduction.
The XH-A901 preamplification module is a preamp circuit that uses the operational amplifier NE5532 (two integrated on the board). This board is designed to improve the sound quality of audio systems by amplifying and adjusting the tone of the signal.
The treble and bass controls allow the user to adjust the tone of the signal to obtain an optimized sound. Also, the XH-A901 preamp board has a high signal-to-noise ratio and low distortion, which means it will pick up sound accurately and faithfully.
Includes connectors for audio input, power and audio signal output. The board allows the adjustment of the total volume, Treble, Middle and Bass. The output from the pre-amplifier is stereo, with two channels, Left and Right.
The integrated NE5532 are inserted in sockets, which makes them easy to change if this is necessary.
