Single Power Supply 10-24V Super Dynamic Bass Boost Front Stage Board with Mono Output

This front stage audio board provides a dedicated solution for enhancing bass response in mono output systems. Designed to operate from a single DC power source between 10 and 24 volts, it offers flexibility for various audio amplifier setups. The board processes input signals from either mono or dual audio channels and consolidates them into a single mono output, focusing on the frequency range from 22Hz to 300Hz. Its construction centres on a durable FR-4 fibreglass printed circuit board, providing a reliable foundation for the bass boost circuitry. With specific mounting dimensions and control spacing, this board is suited for installers who require a component with clear mechanical and electrical specifications.

Features and Construction

The board's design incorporates several measurable features that define its installation and operation. The physical construction and electrical characteristics are detailed to allow for precise integration into larger audio systems.

Material and Build

The core structure of this front stage board is a printed circuit board made from FR-4 fibreglass material. This substrate is described as having super hardness, which contributes to the board's physical durability during handling and installation. The PCB itself has a specification of 78 millimetres in length by 32 millimetres in width, with a consistent thickness of 1.6 millimetres. This provides a compact yet robust platform for the electronic components that facilitate the dynamic bass boost function. The use of FR-4 material is common in electronics for its good electrical insulation and mechanical strength.

Size and Practical Fit

The board's dimensions and mounting points are specified to aid integration. The finished board has a net weight of 30 grams, indicating a lightweight component. For physical mounting, the plate features fixing holes. The centre-to-centre distance between these holes is 70 millimetres in one direction and 24 millimetres in the other, creating a specific mounting pattern. Each hole has a diameter of 3.2 millimetres to accommodate standard fastener sizes. Additionally, the board includes potentiometers for adjustment, and the centre distance between their shafts is specified as 32.5 millimetres. These precise measurements ensure the board can be positioned and secured correctly within an enclosure or chassis.

Uses and Placement

This board serves a specific function within an audio signal chain, typically placed before a power amplifier stage. Its design parameters suit particular application environments, from custom installations to refurbishment projects.

Event or Professional Use

In professional or event audio setups requiring reinforced bass from a mono output, this board can be integrated into amplifier racks or processor units. Its 10-24V power supply range allows it to be powered from common DC sources found in mobile DJ rigs, installed public address systems, or portable sound equipment. The ability to accept dual channel input and output mono is useful for summing signals or dedicating a channel specifically for low-frequency enhancement. The specified mounting hole pattern facilitates secure installation in standard 19-inch rack panels or custom flight cases where vibration resistance is important.

Everyday Home Use

For home audio enthusiasts or DIY builders, this front stage board can be incorporated into custom amplifier projects or used to modify existing equipment to boost bass response. The clear frequency range of 22Hz-300Hz allows users to target the lower end of the audio spectrum. The single power supply requirement simplifies wiring compared to dual-rail designs. The board's compact 78mm x 32mm size makes it suitable for smaller project enclosures. Home users benefit from the defined mechanical specs, such as the 3.2mm fixing holes and 32.5mm potentiometer spacing, which help plan a clean front panel layout for volume or gain controls.

Benefits and Buying Value

The value of this product lies in its specified performance parameters and construction details, which provide clarity for selection and application. It offers a focused solution for a particular audio processing need.

Reuse and Low Maintenance

The use of an FR-4 fibreglass PCB, known for its stability, supports the board's potential for long-term use. The defined voltage range and signal specifications allow the board to be repurposed across different projects if needed. With no moving parts and a simple component list, it requires minimal maintenance once installed correctly. The provided mounting hole specifications aid in creating a secure, permanent installation that reduces the risk of connection issues from movement or vibration.

Why Choose This Product

This board is chosen for applications where a specific bass boost function is required for a mono audio output, and where the system power supply falls within the 10-24V DC range. Its value comes from having clear, measurable specifications for voltage, frequency, physical size, and mounting. This allows buyers to verify compatibility with their existing equipment or project plans. The product provides a dedicated circuit block, saving the user from designing a similar function from individual components. The inclusion of all necessary mechanical dimensions enables precise planning for installation, which is a practical advantage over boards with unspecified mounting details.
