Super Dynamic Bass Boost Front Stage Board with 10-24V Single Supply and FR-4 PCB

This front stage audio circuit board is designed to add a dedicated dynamic bass enhancement stage to your audio system. Its core function operates within a 22Hz to 300Hz frequency band, targeting the low-end spectrum for a more pronounced bass response. A key practical feature is its compatibility with a wide single DC power supply range from 10V to 24V, simplifying power integration in various setups from automotive to fixed installations. The board accepts either a mono or a dual-channel audio input and outputs a processed mono signal, making it a versatile component for system upgrades where bass management is desired.

Features and Construction

This board's design is centred on providing a specific audio processing function with clear physical and electrical specifications for integration.

Material and Build

The circuit is built on a super-hardness FR-4 fibreglass printed circuit board (PCB). This material is commonly used in electronics for its rigidity and good insulating properties, providing a stable platform for the board's components. The PCB itself has a stated thickness of 1.6mm, contributing to its structural integrity. The finished assembly has a net weight of 30g, indicating a compact and relatively lightweight build suitable for installation in confined spaces.

Size and Practical Fit

The board's compact footprint measures 78mm in length by 32mm in width. This size allows it to be fitted into many audio racks or enclosures. For secure mounting, the PCB includes pre-drilled fixing holes. The centre-to-centre distance between these holes is 70mm along one axis and 24mm along the other, with each hole having a diameter of 3.2mm to accommodate standard mounting hardware. Furthermore, the board layout specifies a 32.5mm centre-to-centre distance for potentiometer shafts, guiding the placement of external control knobs for user adjustment.

Uses and Placement

The board's specifications suggest several practical applications where adding a dedicated bass processing stage is beneficial.

Event or Professional Use

In professional or event audio setups, this board could be integrated into a signal processing rack to provide a standalone bass boost for specific channels or a subgroup. Its 10-24V power range allows it to be powered from common DC supplies used in portable PA equipment or rack-mounted power distributions. The ability to accept dual-channel input offers some flexibility in how source signals are routed into the bass enhancement stage before being output as a consolidated mono signal.

Everyday Home Use

For the home audio enthusiast, this front stage board presents a component-level upgrade option. It could be incorporated into a custom-built amplifier, a subwoofer processor, or a modular effects unit to tailor the bass response of a music system or home theatre setup. The specified frequency range of 22Hz-300Hz allows users to augment the low-end output of their existing speakers or to better integrate a dedicated subwoofer.

Benefits and Buying Value

The value of this product lies in its defined function and the concrete specifications provided for integration.

Reuse and Low Maintenance

As a circuit board, its primary maintenance involves correct installation and handling. The robust FR-4 fibreglass material supports repeated use once installed. The product's value is realised through its ongoing function within a larger audio system, providing a specific processing effect without the need for consumable parts or complex upkeep, assuming it is operated within its stated electrical limits.

Why Choose This Product

You would select this board if you require a defined circuit to add a dynamic bass boost to an audio signal path and need a component with clear voltage, frequency, and physical dimensions. Its precise specifications—like the 78x32mm PCB size, 10-24V supply range, and 22-300Hz frequency focus—allow for informed planning and integration into a project, compared to a generic or unspecified audio module.
