Alpine Introduces New Car Audio Processor

Alpine Electronics of America is shipping a new processor with 25 watts of built-in power and a new user interface.

The PXE-0850X is an advanced, wireless, Digital Sound Processor (DSP) replacing the PXE-0850S with an upgraded user interface that matches that of the PXE-X09 (introduced in 2020). It offers a cleaner layout that simplifies mixing and tuning.

The PXE-0850X has 6 low and/or high-level inputs that can be mixed to create a full range signal that sends up to 12 independent channels for system building. Eight of the 12 channels can use 25W of powered output.

The processor can be tuned wirelessly over Bluetooth from a phone or via a wired USB connection to a PC. Users can see real time tuning results and compare “Before” and “After” effects once they download the PXE-0850X app.  Tuning files can be saved directly to a smartphone, hard drive, or thumb drive for storage and shared via text message or email.

The PXE-0850X can also be used as a head unit or music source with wireless streaming over Bluetooth.

It has an improved LCD controller with a rotary knob that can be flush-mounted on the dash.

Street price of the PXE-0850X is $699.95.
