【BRAX GX-2400 Short Black｜High-Quality Power Amplifier for Car Audio】

The BRAX GX-2400 Short Black is designed for those who want to fine-tune the sound of their car audio even more.
It’s a power amplifier worth considering if you want to bring out the speakers’ character while placing importance on sound detail and imaging.

The GX2000 / GX2400 are power amplifiers in the newly developed Graphic-Series, inheriting the core design cultivated in the higher-end series. The power supply section uses features such as 3-parallel drive with MOS-FET, a large toroidal transformer, a dual-bridge circuit, and high-capacity custom capacitors. With a stable power supply design, the aim is to reproduce not only the subtle nuances of sound, but also the spatial relationships between instruments with care.

The input stage uses a Burr-Brown IC op-amp and custom film coupling capacitors. There is no built-in crossover, to keep the signal lines short. Since it is designed with the assumption that adjustments will be made externally to match the system configuration, it is also suitable for those who want to create a sound tailored to the in-car environment by combining it with a DSP or processor.

It is also equipped with terminals for connecting external capacitors. Rather than considering the amplifier in isolation, combining it with components such as the head unit, DSP, speakers, and the power-supply section makes it easier to take advantage of the strengths of the GX-2400.

The Black model of the Short Version features a compact design that does not cover the connection terminals. Because the most suitable model and installation method can vary depending on mounting space and the overall system configuration, it’s reassuring to choose while checking the actual vehicle and your current audio setup.

An amplifier is not a product that produces the same sound once installed. The final result changes depending on how the power and wiring are handled, the installation method, gain adjustments, and the balance with other equipment. If it were me, I would first confirm the audio issues you currently have and the direction you want to aim for, then organize together whether your system would actually benefit from adding the GX-2400. Adding expensive equipment alone is not necessarily the right answer—so we’ll guide you to suit your vehicle to help ensure you don’t end up with a sound that’s different from what you expected.
