• As more and more newer vehicles are equipped with highly integrated displays and complex sound systems, the stand-alone DSP, Digital Signal Processor, is becoming absolutely crucial for building the next-level Alpine sound system..
• The PXE-0850S comes with an LCD remote controller that can be flush-ed on the dash. Use the rotary knob to quickly control volume, preset storage and recall, and source selection. You can also view the results on the remote controller’s LED screen..
• Once you’ve designed the perfect configuration of speakers and amps for your system, the new Alpine DSP allows you to dive deep into tuning the system..
• Tuning doesn’t have to be complicated. The PXE-0850S allows you to easily custom tune your system wirelessly on a , , or via wired USB connection for PC.
• Aside from using Bluetooth to wirelessly tune the system, the PXE-0850S also has Bluetooth streaming which allows you to bypass your head unit altogether and send audio from your phone directly to the processor..

Set your sound stage and bring a whole new music experience to life with the PXE-0850S Wireless Digital Signal Processor. This processor overcomes inherent acoustical anomalies within vehicles to develop a well-balanced response and proper sound stage even from a factory head unit. Customize your system with the 31-band EQ and make precise adjustments to the detailed high/low crossovers and expansive time correction for each of the 12 channel. Easily control the PXE-0850S wirelessly via a connection or a wired connection to your PC -- either way, you get fast, real-time results.
