【HELIX・MATCH・BRAX DSP-Compatible DRC AC Digital Remote Controller】

When you want to adjust the volume in your car, change the subwoofer level, or switch between music sources and sound presets—DRC AC lets you control everything intuitively right at your fingertips, instead of repeatedly operating your smartphone or the DSP’s settings screen.

With a multifunction dial and a high-resolution OLED display, you can operate smoothly while checking the system status. If you can install it in a position that’s easy to reach even while driving, sound adjustments in everyday use become much more familiar.

Main operations you can do with DRC AC

• Master volume adjustment
• Subwoofer level control
• Source select (external input switching)
• Sound preset switching
• Loudness adjustment, etc.

Supported functions vary depending on the DSP model you connect, but it is a controller designed to make HELIX・MATCH・BRAX DSP-based systems easier to operate from your seat.

For example, when you want to listen with the volume slightly lower as usual, when you want to fine-tune the subwoofer “amount” only while driving, or when you want to switch sources such as music or video. The convenience is that you can perform the operations you use most often in the car without having to navigate deep through the screen.

Also supports switching sound presets

If you prepare multiple sound settings in the DSP, you can also switch presets according to your preferences.

Even with the same song, you may want a different sound balance when listening primarily from the driver’s seat versus enjoying it together with passengers. By combining DRC AC, it becomes easier to choose the right sound for each situation.

At our store, we produce up to two setting data sets for free according to your requests. If you want three or more settings, additional adjustment fees will apply.

Parts to consider including installation position and tuning

A remote controller’s real usability changes depending on where it’s mounted and how easy it is to operate. It’s important to design a setup that you can use comfortably while confirming the vehicle model, the interior shape, and the positional relationship with the OEM switches.

Also, to make the most of DRC AC, DSP-side settings and the creation of sound presets are essential. We’ll adjust the system to match how you actually use it—not just by installing the product, but by confirming which operations you want to use and how you usually listen to music.

If you’re using HELIX・MATCH・BRAX DSP and want to operate volume, subwoofer, and sound presets more easily, this is a controller worth considering. Since the information we can offer varies depending on your vehicle specifications and the DSP model, let’s think it through together while checking your current system.
