ZERO-R USB A-miniB (3m)

A 3m dedication that connects your car’s music time.

【BRAX/HELIX/MATCH DSP Dedicated ZERO-R USB A-miniB (3m) Noise-Less USB Audio Cable】

A USB audio cable dedicated to the USB HD AUDIO INPUT MODULE of BRAX/HELIX/MATCH DSP, for those who are bothered by noise when connecting via USB or by sound smearing.

The ZERO-R USB A-miniB (3m) is characterized by its power-wiring-free design. By suppressing the impact of noise associated with USB connection, it helps you perceive the sound’s contours as sharper. If you want to clearly pick up fine details, or if you are honing the playback sound with a DSP, it’s well worth reviewing the signal path—including the cable.

As a specification unique to the terminal manufacturer, the connector interior is finished with a three-layer rhodium coating. Although this is difficult to see from the outside, it’s a point worth noticing for those who want to carefully optimize the USB connection—the sound’s entry point.

Please note, however, that this cable is intended exclusively for the compatible USB HD AUDIO INPUT MODULE. Since the connection method and the way the effect shows may vary depending on your DSP and system configuration, it’s best to confirm your current listening setup and audio concerns and choose accordingly—rather than simply swapping the cable.

At Log On, we consider together whether changing the cable makes sense, taking into account not only the DSP unit’s settings but also the system configuration inside the vehicle. Instead of rushing to assume what the sound change means, I would suggest—looking at the overall balance—where you should fine-tune the current system.
