Not available online


The PXE-0850X offers music enthusiasts the ultimate audio experience. The PXE-0850X is a DSP sound processor and consists of advanced digital sound processing technology through innovative software including tuning wirelessly via a smartphone app or PC software via USB connection. Extreme sound can be achieved with key features such as 31-bands of EQ adjustment, parametric filters, signal time-alignment, input delay and time correction. The 6 channel utilises the in-built digital amplifier while the 12 channel RCA outputs provide the use of an external amplifiers, a combination of both functions can be used to support any sound configuration.

A series of ultra-high performance audio components have been built-in to achieve Alpine’s heritage quality sound.

12 Channel RCA Output

The 12 Channel RCA outputs allow for the setup of virtually any system configuration. The connection of external amplifiers to the outputs to allow for the use of 2-way and 3-way speaker systems with a subwoofer.

Extreme Sound Tuning

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. Objects and materials in the vehicle (seats, center consoles, leather, glass, etc.) all contribute to the overall sound entering your ears. Many times, these contributions are undesirable. Using professional tools like Real-Time Analyser, (sold separately) allows you to identify these issues and adjust crossovers and levels of each speaker to ensure proper balance across your system. Timing from each speaker location can be delayed so the sound reaches your ears at the same time—allowing you to stage your music properly. Finally, the 31-band parametric and graphic equaliser lets you to dial down unwanted frequencies and flatten the response to ensure your sound system is properly replicating the music exactly as the artist intended.  

Smartphone Sound Tuning

Tuning doesn’t have to be a complicated. The PXE0850S allows you to easily custom tune your system wirelessly on a smartphone, tablet, or via wired USB connection for PC (USB cable included0. No matter your preference, you get one convenient place to see all the inputs/outputs, crossovers, time correction, and 31 bands together for immediate visual recognition and real-time sound results. Listen with delight as you pull frequency levels (“Q’s”) and immediately hear the adjustment being made. Quickly turn off an adjustment with one touch to listen to the ‘Before’ and ‘After’ effect.
