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

The XH-A901 Preamplifier Tone Board is a compact audio component designed to sit between your source and power amplifier. It provides audio amplification alongside high, mid and low frequency adjustment, giving you practical control over your listening setup. The board is built around the original dual-core NE5532 chip and operates on a DC supply of 12 to 24V, making it a straightforward addition to a range of amplifier projects. Tone Control and Adjustment With dedicated controls for treble, bass and volume, the board lets you tailor the sound to suit your room, speakers or personal preference. The high, mid and low frequency adjustment allows for fine-tuning across the range, so you can shape the output rather than relying on a fixed signal. This makes it particularly useful for DIY audio builds or for upgrading an existing amplifier chain where simple volume control is not enough. Installation Notes The board is intended for use with power amplifiers and connects via a 3P audio cable for input. When wiring, take care to distinguish between the positive and negative terminals to ensure correct operation. Please note that the colour of the board may vary, as it is supplied at random and is not selectable by specification.
