【ARC Audio PSC | Fine-Tuning In-Car Sound with a 12-Channel DSP Power Amplifier】

If you want a bit more sense of spaciousness and depth in your factory audio—or if replacing your speakers alone didn’t quite pull together the sound the way you expected—then you should consider ARC Audio’s PSC.

The PSC is a model that combines a 12-channel power amplifier with a DSP function. It supports 24bit/96kHz and wideband playback up to 40kHz. While processing the music signal in detail, it lets you control each in-car speaker appropriately.

Simply turning up the volume like a typical amplifier is not an easy way to get audio that sounds good and is easy to listen to inside a car. The distance from the speakers differs between the driver’s and passenger’s seats, and there are reflections caused by the dashboard, doors, and glass. With a multi-channel DSP amplifier like the PSC, it becomes easier to adjust the sound balance to match the car’s environment.

You can create sound tailored to your goals—such as making vocals easier to hear in the center, getting the bass to hit a little more firmly, or building a system that won’t get messy even when you raise the volume. With 12-channel output, and support for control up to 14 channels, it’s also a configuration that’s easy to adapt to systems that combine front/rear speakers and a subwoofer.

Power output is 60W×12 at 4Ω, and 90W×12 at 2Ω. With high-efficiency operation enabled by a Class D design, the rated power efficiency is 80%. Maximum power consumption is limited to 45A, which is another advantage when building a system as a 12-channel amplifier. The enclosure is also relatively compact, making it a model that’s easier to consider for installation in limited in-car space.

However, a DSP amplifier isn’t a product that finishes the sound just by being installed. The connection method with the factory system, speaker configuration, whether a subwoofer is included, and the characteristics of each speaker will all change what settings and adjustments are needed. Even using the same PSC, the overall impression of the final sound will vary depending on how you combine components and how far you adjust.

At LOGON, we look at whether there is a reason to use the PSC together—after confirming your vehicle model, your current audio setup, what music you usually listen to, and the direction of sound you want to achieve. Whether you’ve already replaced your speakers or you want to build an entire system from here, we propose a realistic configuration that fits your current car—without unnecessarily increasing equipment.

If you want to enjoy the changes in sound while building a car audio system you can use for a long time, try consulting us with the PSC as a candidate.
