XH-A901 Preamplifier Tone Board with Bass Treble Volume Control for Amplifier

XH-A901 Preamplifier Tone Board This XH-A901 preamplifier tone board is designed for use with power amplifiers, giving you control over your audio before it reaches the amplification stage. It provides audio gain along with adjustable high, mid and low frequency response, allowing you to tailor the sound to suit your listening preferences and room acoustics. Tone Control and Audio Adjustment The board features dedicated controls for treble, bass and volume, so you can fine-tune the output to match your speakers and source material. Whether you prefer a warmer sound with enhanced low end or a brighter, more detailed top end, the adjustment options give you the flexibility to shape the audio to your liking. Technical Specifications and Installation The preamplifier operates on a DC 12–24V supply and uses the dual-core NE5532 chip for signal processing. When wiring the board, take care to distinguish between the positive and negative terminals, and note that the audio input uses a 3-pin audio cable. This board is intended for integration into an existing amplifier setup rather than as a standalone unit.
