10-24V Single Supply Super Dynamic Bass Boost Front Stage Audio Board

This front stage audio processing board is designed to add a dedicated low-frequency enhancement channel to an audio system. Its core function is to provide a 'super dynamic bass boost' within a specified 22Hz to 300Hz frequency range, making it a practical module for car audio, portable speaker modifications, or other projects requiring emphasised bass response. The board simplifies integration by requiring only a single 10-24V DC power supply, eliminating the need for complex dual-rail power setups. Presented as a finished PCB, it arrives ready for installation into your audio project.

Features and Construction

This board is defined by its electrical specifications and physical build, which are geared towards reliable performance and straightforward mounting.

Material and Build

The circuit is constructed on a super hardness FR-4 fibreglass printed circuit board (PCB). FR-4 is a standard, flame-retardant composite material known for its good electrical insulation properties and mechanical stability, providing a durable base for the electronic components. The PCB itself has a thickness of 1.6mm, a common standard that offers a balance between rigidity and weight, contributing to the board's overall net weight of 30 grams.

Size and Practical Fit

The board's compact dimensions are precisely 78mm in length by 32mm in width. This size allows it to be fitted into various enclosures or audio system cavities. For secure mounting, the PCB includes fixing holes. The centre-to-centre spacing of these holes is 70mm by 24mm, and each hole has a diameter of 3.2mm, suitable for standard M3 screws or bolts. Additionally, the board features potentiometers (likely for gain or frequency adjustment) whose control shafts are positioned with a fixed 32.5mm centre spacing, which is useful for panel layout when selecting matching knobs.

Uses and Placement

The board's specifications guide its application, focusing on scenarios where enhanced bass is desired without major system overhauls.

Event or Professional Use

For small-scale PA systems, DJ setups, or installation audio where the existing amplification lacks tailored bass management, this board can serve as an add-on module. Its 22-300Hz frequency range targets the fundamental bass and lower-mid frequencies, allowing it to be integrated into a signal chain before a power amplifier to drive a dedicated subwoofer or to enhance main speaker output. The mono audio output is typical for bass signals, which are often summed to a single channel.

Everyday Home Use

In DIY audio projects, this board can upgrade a basic amplifier kit or a multimedia speaker system by adding a user-controllable bass boost circuit. Hobbyists can incorporate it into a custom-built Bluetooth speaker, a computer sound system, or a home theatre subwoofer amplifier. The single 10-24V power supply requirement means it can often be powered from an existing system's power rail or a simple wall adapter, simplifying the build process.

Benefits and Buying Value

The value of this product lies in its specificity and the practicality it offers to audio enthusiasts and builders.

Reuse and Low Maintenance

As a circuit board module, its primary maintenance involves ensuring clean electrical connections and preventing physical damage. The FR-4 substrate is resilient to typical environmental stresses found in electronic devices. The board itself has no moving parts, suggesting a design focused on long-term reliability within its operational parameters.

Why Choose This Product

This board is a direct solution for anyone seeking a pre-assembled, functional bass boost circuit with clear specifications. It saves time and effort compared to sourcing individual components and designing a PCB from scratch. The provided dimensions and mounting hole pattern allow for precise planning during project enclosure design. Choosing this product means acquiring a tested audio module focused on a specific task: dynamically boosting bass frequencies within a defined range using a commonly available power supply voltage.
