Features and Construction

The amplifier board combines specific electrical specifications with physical construction details that determine its installation and performance characteristics. With measurements and materials clearly specified, users can assess compatibility with their existing audio setups and mounting requirements.
Material and Build
Constructed using super hardness FR-4 fibreglass board, this PCB provides the structural foundation for the bass boost circuitry. The FR-4 material offers electrical insulation properties suitable for audio frequency applications while maintaining rigidity for secure component mounting. The board thickness measures 1.6mm, providing sufficient substance for through-hole component installation without excessive bulk. This construction approach balances durability with practical weight considerations, resulting in a finished board weighing 30g that can be mounted securely without adding significant mass to audio installations.
Size and Practical Fit
With dimensions of 78mm by 32mm, the board presents a compact footprint suitable for integration into various audio enclosures and system layouts. The fixing holes are positioned with centre spacing of 70mm by 24mm, allowing secure attachment using standard M3 hardware through the 3.2mm diameter holes. Potentiometer shafts are spaced 32.5mm apart centre-to-centre, providing adequate clearance for adjustment knobs without interference. These precise measurements enable installers to plan mounting locations accurately and ensure proper alignment with control panels or enclosure cutouts in custom audio projects.
Uses and Placement

The board's electrical specifications and physical characteristics determine its suitable applications and installation scenarios. From professional audio installations to DIY projects, the single power supply requirement and bass-focused frequency response offer specific advantages in particular use cases.
Event or Professional Use
For professional audio applications, this board can enhance bass response in compact sound systems used for mobile DJ setups, small venue installations, or portable PA equipment where space and power simplicity are priorities. The 10-24V DC power range compatibility makes it suitable for systems powered by batteries, vehicle electrical systems, or standard DC power supplies commonly used in portable professional audio gear. The mono output configuration works well for subwoofer channels or combined bass signals in multi-speaker setups, while the frequency range specifically targeting 22Hz-300Hz allows audio technicians to boost the lower end without affecting mid-range clarity.
Everyday Home Use
For home audio enthusiasts, this board offers bass enhancement options for custom speaker projects, car audio upgrades, or computer sound system modifications. The single power supply requirement simplifies integration with existing 12V car electrical systems or commonly available DC power adapters for home use. DIY audio builders can incorporate the board into subwoofer enclosures, speaker cabinets, or audio processing units to add adjustable bass boost functionality. The compact dimensions allow installation in limited spaces within existing audio equipment, while the super hardness FR-4 construction provides durability for long-term use in various environmental conditions typical of home audio setups.
Benefits and Buying Value

This amplifier board offers specific practical advantages stemming from its design specifications and construction approach. By focusing on core functionality within defined parameters, it provides value through application-focused performance and straightforward integration.
Reuse and Low Maintenance
The board's construction on super hardness FR-4 fibreglass contributes to long-term reliability in typical audio installation environments. This material choice provides resistance to vibration and mechanical stress that might occur in mobile audio applications or equipment that undergoes regular movement. With no moving parts beyond the potentiometer adjustments, the board requires minimal maintenance beyond occasional contact cleaning if control responsiveness diminishes over time. The through-hole component mounting approach facilitates component replacement if necessary, extending the usable lifespan of the board beyond surface-mount alternatives that require specialised repair equipment.
Why Choose This Product
This amplifier board addresses specific audio enhancement needs with clearly defined parameters that allow informed purchasing decisions. The single power supply operation from 10-24V DC eliminates the complexity and cost associated with dual-voltage power supplies, making it suitable for applications where power simplicity is valued. The focused frequency range of 22Hz-300Hz provides bass enhancement without attempting to process the entire audio spectrum, which can be advantageous when integrating with existing audio processing equipment. The physical dimensions and mounting hole placements enable straightforward installation planning, while the super hardness FR-4 construction offers durability appropriate for the intended audio enhancement applications without claims beyond the stated material specification.
