XH-A901 Preamplifier Tone Board with Bass Treble Volume Control, DC12-24V, for Amplifier

The XH-A901 Preamplifier Tone Board is a compact audio control module designed to sit between your audio source and a power amplifier. It provides a practical way to add tone shaping to a stereo system, allowing you to adjust the output to suit your listening environment and personal preferences. Tone Adjustment and Audio Control The board provides dedicated controls for bass, treble, and volume, giving you direct command over the sound profile. This allows you to fine-tune the audio to compensate for room acoustics or simply to enjoy a warmer or brighter presentation. The preamplifier stage is built around the dual-core NE5532 chip, a well-regarded operational amplifier known for its low noise and good fidelity, which helps ensure clean signal processing. Installation and Power Requirements The board operates on a DC supply voltage of 12 to 24V, offering flexibility for various system setups. Please note that the colour of the board may vary, as it is supplied randomly and is not a selectable specification. During installation, it is important to observe correct polarity and distinguish between the positive and negative terminals. The audio input connection uses a 3-pin audio cable, and careful wiring is essential for proper operation.
