XH-A901 NE5532 Tone Board Preamp Treble Bass Price in Bangladesh

The XH-A901 NE5532 Tone Board Preamp Treble Bass is a compact audio preamplifier and tone-control module designed for DIY audio amplifier and stereo projects. It uses the popular NE5532 operational amplifier to process low-level audio signals and provides user-adjustable bass and treble control.

This type of module can be placed between an audio source and a power amplifier stage. The tone-control section allows the listener or system designer to adjust the balance of low- and high-frequency content according to the desired sound profile.

The XH-A901 is useful for electronics enthusiasts, audio hobbyists, amplifier builders, and students working on analog audio circuits. Its ready-made PCB design reduces the need to build the complete preamplifier and tone-control circuit from individual components.

Overview of XH-A901 NE5532 Tone Board

The XH-A901 combines audio preamplification with tone adjustment in a compact PCB module. The NE5532 is a well-known dual operational amplifier commonly used in audio circuits because of its suitability for low-noise analog signal processing.

The board is designed to receive an audio signal, process it through the preamplifier and tone-control stages, and provide a suitable output for a following amplifier stage.

The bass control affects the lower-frequency portion of the audio spectrum, while the treble control adjusts the higher-frequency portion. This allows users to modify the overall tonal character of an audio system without changing the original audio source.

What Is an Audio Tone Control Preamplifier?

An audio tone-control preamplifier is an electronic circuit that performs two main functions: conditioning a relatively low-level audio signal and adjusting selected frequency ranges.

A preamplifier prepares the signal for the next stage of an audio system, while a tone-control circuit allows changes to frequency response. Bass and treble controls are commonly implemented using potentiometers and active or passive filter networks.

The XH-A901 combines these functions into a convenient PCB module.

Technical Specifications

Note: XH-A901 boards can be sold in different revisions and layouts. Power-supply requirements, connector arrangement, gain, frequency response, and other electrical specifications may vary between versions. Verify the markings on the specific board before installation.

Working Principle

The XH-A901 receives an analog audio signal from a suitable audio source. The signal is processed by the audio circuitry built around the NE5532 operational amplifier.

The preamplifier stage conditions the incoming signal so it can be properly passed to a subsequent amplifier stage. The tone-control section uses frequency-selective circuitry to adjust the relative level of bass and treble components.

When the bass control is adjusted, the circuit changes the response of the lower-frequency portion of the audio signal. Similarly, the treble control changes the response of the higher-frequency portion.

After tone adjustment, the processed audio signal is delivered to the output of the module for connection to a compatible downstream amplifier or audio stage.

Applications

The XH-A901 NE5532 Tone Board can be used in various analog audio projects, including:

• DIY stereo amplifier projects
• Home audio amplifier modifications
• Audio preamplifier systems
• Bass and treble adjustment circuits
• Analog audio experiments
• Custom speaker amplifier projects
• Educational electronics projects
• Audio signal-processing prototypes
• DIY desktop audio systems
• Electronic musical-instrument projects
• Audio equipment repair and modification
• Custom amplifier enclosure projects

Advantages

The XH-A901 provides several useful functions on a single compact PCB. Instead of designing a complete NE5532-based preamplifier and tone-control circuit from individual components, users can integrate a ready-made module into a compatible audio project.

The separate bass and treble controls provide convenient adjustment of the sound characteristics. The use of the NE5532 also makes the board relevant to users who want to experiment with classic analog audio signal-processing circuits.

Its small form factor can be useful when adding tone adjustment to an existing DIY amplifier enclosure.

Limitations

The XH-A901 is an audio preamplifier and tone-control stage rather than a high-power speaker amplifier. It normally needs to be connected to a suitable power amplifier if the final application requires enough power to drive a speaker.

Performance also depends on the particular board revision, power supply, connected audio source, downstream amplifier, wiring, grounding, and overall system design.

Because different XH-A901 versions may use different PCB layouts or supporting components, exact electrical specifications should be confirmed from the particular board before integrating it into a finished product.

Installation and Usage Tips

Before connecting the XH-A901, identify the board’s power, audio input, and audio output terminals according to the markings on the particular PCB.

Use a suitable power source matching the board’s specified supply requirements. Do not connect the module directly to an inappropriate voltage source.

Keep audio signal wiring reasonably short and organized to reduce the possibility of unwanted noise or interference. Proper grounding is also important in analog audio systems.

Connect the output of the tone board to a compatible amplifier input rather than directly treating the module as a high-power speaker driver. Start with moderate control settings and verify the signal path before integrating the board into a permanent audio system.

Why Choose XH-A901 NE5532 Tone Board?

The XH-A901 is a convenient choice for DIY audio enthusiasts who need bass and treble adjustment together with an analog preamplifier stage. Its compact PCB format and NE5532-based design make it suitable for amplifier projects, audio experiments, and custom sound systems.

For students and electronics hobbyists, the board can also provide a practical platform for learning about operational amplifiers, audio preamplification, active tone controls, frequency response, and analog signal processing.
