About the Alpine PXE-0850S
Make your system sound spectacular
Make your system sound spectacular
Talk about a jack-of-all-trades. Alpine's PXE-0850S amplifier/processor will deliver high-fidelity sound to almost any car audio system, aftermarket or factory. The PXE-0850S can be used as a stand-alone sound processor, taking up to six inputs — from a factory system's high, midrange, and low frequencies for example — and providing twelve processed channels to feed your amplifiers. The PXE-0850S can also serve as a factory system upgrade — an amplifier with onboard sound processing — sending 25 watts RMS each to up eight separate speakers. This handy little magic box comes with a Bluetooth® adapter so you can stream music wirelessly from your compatible device without even needing a receiver in your system.
You control the PXE-0850S's 32-bit 300 MHz processing wirelessly with your compatible Bluetooth device or with a Windows-run PC via the supplied USB cable. You download the free PXE-DSP-APP for iOS or Android device from the Apple APP or Google Play Store. The PXE-DSP-APP for Windows is available at Alpine.com.
The control app
Matrix mixing allows for summing and input/output signal management. Fully adjustable high-pass, low-pass, and bandpass filters on every channel match the sound to your speakers. The 31-band equalizers help achieve the perfect tone, allowing you to smooth out any hot spots or dips in the frequency response of your vehicle's interior. The delay feature lets you center the stereo image for your listening position.
The PXE-0850S comes with a wired LCD remote controller so you can control volume, store and recall presets, and select between sources from the driver's seat.

Overview: The Alpine PXE-0850S Advanced Wireless Digital Sound Processor lets you customize your vehicle's sound system for the best sound quality and sound staging. The processor can be used with a factory system, or with and Alpine or other brand of head unit. With 31 bands of independent equalization per channel and multiple crossovers, the processor can help you dial in the sound that's right for your vehicle. It has 6-channels of high- or low-level input from your factory or aftermarket head unit, with 8 speaker outputs and 12 preamp outputs. The PXE-0850S can connect to a Windows PC via USB, a Bluetooth-connected smartphone, or the included Remote Commander for making all your adjustments. The processor comes with a power/ground/speaker input harness, two speaker output harnesses, and a USB 3.0 interface cable.
Construction: The PXE-0850S is equipped with a Texas Instruments 32-bit DSP with 300MHz floating point processor, and a TI 24-bit premium A/D and D/A converter. The unit lets you take up to six independent signals (low, mids, and highs per side, for example) and combine them into a full range signal. This full range signal can be sent to up to 12 independent channels for an extremely versatile system.
Inputs: The processor features six channels of speaker-level inputs on the included harness and 3 pairs of RCA line level inputs on the unit. In addition, the PXE-0850S has optical (Toslink) and coaxial (RCA) S/PDIF digital inputs to play music from an in-vehicle CD or DVD, and an external Bluetooth module for connecting your smartphone.
Outputs: The PXE-0850S has 25 watts RMS output per channel x 8 channels for powering multiple pairs of speakers. It also has 12 channels of preamp level outputs. The signal of the speaker outputs mirror the first 8 RCA output channels.
User Interface Options: The Alpine PXE-0850S Digital Sound Processor can be controlled in three different ways:
- Mobile Phone App: The Alpine PXE-DSP-APP application lets you control the processor from your smartphone or tablet. The smart device connects via Bluetooth through the included External Bluetooth interface. The PXE-DSP-APP allows you to adjust the Master Volume, Switch the Output Channels to adjust, Set the EQ curve, Q-value, and Frequency Tuning, Set the Crossovers, Set the Delay, and Set the Audio Output Mixing. The app is compatible with Apple devices running iOS 8.0 or later, and Android devices with version 4.0 and up.
- PC Software: You can connect a PC to the processor via the included USB 3.0 cable. The functions of the PC software are the same as the Mobile Phone app. The graphic displays on the PC are much more detailed than the Mobile Phone App. The PC software runs on Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 10.
- Wired Controller: The included Remote Commander has limited control via its large rotary control and 1-3/8" display. The Remote Commander can adjust the Master Volume, switch the audio input source (S/PDIF, Hi.Level, Phone (Bluetooth), Aux (low level)), and set and recall the Preset Sound Effects. Further detailed settings must be made through the Mobile Phone App or PC Software.
Equalization: The PXE-0850S features 31-bands of independent equalization per channel, with both parametric and graphic EQs. In the Parametric EQ, you can adjust the frequencies between 20Hz and 20kHz. In the Graphic EQ, the frequency bands are set 1/3-octave intervals at 20, 25, 32, 40, 50, 63, 80, 100, 125, 160, 200, 250, 315, 400, 500, 630, 800, 1000, 1250, 1600, 2000, 2500, 3150, 4000, 5000, 6300, 8000, 10000, 12500, 16000, and 20000 Hz. The slope (or Q value) is adjustable between 0.404 and 28.85 in 0.01 increments. The gain of each band can be increased or decreased by up to 12dB in 0.1dB increments.
Crossovers: Each output is equipped with independent high- and low-pass filters. Bandpass filters can also be configured. For each channel, you can select the type of filter - Butterworth, Linkwitz-Riley, or Bessel. Crossover points are fully adjustable from 20Hz to 20kHz in 1Hz increments. You can choose from the following crossover slopes: 12dB, 18dB, 24dB, 30dB, 36dB, 42dB, or 48dB per octave.
Time Correction/Phase: The PXE-0850S can apply a wide degree of time correction to each of the 12 channels of output: Left and right front (low, mid, tweeter), Center, Left and right rear (mid, tweeter), and Subwoofer. You can choose the amount of delay in milliseconds (0.000 to 20), centimeters (0.00 to 692 cm) or inches (0.00 to 273"). The phase of each output can be set to positive (0°) or inverted (180°).
Presets: After you have set the EQ frequency, Q-value, and gain data, delay, channel, and phase position settings to your liking, you can save them to one of up to six different sound presets. This allows you to make different sound settings for each input type or music genre.
Protected Settings: Current settings can be protected by a six-digit password. The values of the 31-band EQ frequency, Q-value, and gain data, delay, channel, and phase settings are encrypted to prevent accidental changes or deliberate tampering with the settings.
