Alpine PXE-X09

We’re encountering more and more large, multi-speaker sound systems in many newer vehicles that just don’t sound very good. Alpine’s PXE-X09 digital signal processor (DSP) solves this problem by offering up to sixteen channels of processing that will improve the sound coming from every speaker tucked into every nook and cranny inside your vehicle.

• Crazy connectivity

  This processor will work with an aftermarket receiver, using the left and right front, rear, and subwoofer outputs, for example, for the processor’s inputs, and then mix and route the signals to sixteen outputs feeding sixteen channels of amplification. The PXE-X09 can also get connected using the factory amplified signals intended for all those speakers — Alpine includes speaker wire to RCA adapters to facilitate that connection method.

• Digital inputs

  If you’re lucky enough to have a car stereo with a digital output, the PXE-X09 features coaxial and optical digital inputs for the cleanest connections possible. The processor comes with a Bluetooth dongle so you can both stream content into the system from your compatible device and control the DSP tuning app.

• The control app

  You control the processing with a Windows-run PC via the supplied USB cable or wirelessly with your compatible Bluetooth device. You download the free PXE-X09 Tuning App for iOS or Android device from the Apple APP or Google Play Store. The PXE-X09 Sound Manager for Windows is available at Alpine.com.
