The Alpine PXE-X120-8 is a 12-channel, high-resolution digital sound processor (DSP) with a built-in amplifier, designed to upgrade and fine-tune car audio systems. It offers extensive tuning capabilities via PC or smartphone app, matrix input summing, and a variety of input/output options. 

Key Features and Specifications

High-Resolution Audio: Supports Hi-Res Audio with a sampling rate of 96kHz/24bit and a frequency response of 20Hz ~ 40kHz, ensuring high-fidelity sound reproduction.

Built-in Amplifier: Features an integrated amplifier providing 4 channels x 25W RMS + 4 channels x 50W RMS for powering speakers directly.

Extensive Connectivity:

Inputs: 12-channel high-level, 2-channel RCA, HD Bluetooth, optical, and coaxial digital inputs.

Outputs: 8-channel high-level, 12-channel RCA pre-outs.

Advanced Audio Tuning:

Equalizer: 31-band parametric or graphic EQ per channel, with adjustable frequency, Q value, and gain.

Crossover: High-pass, low-pass, and band-pass filters per channel with selectable slopes (12dB to 48dB/octave).

Time Correction: Up to 20ms of time delay per channel for precise sound staging.

Phase Adjustment: 0 or 180-degree phase adjustment per channel.

Matrix Summing: Allows summing of input signals to manage complex factory audio systems.

Control Interface: Sound tuning is done through a dedicated PC software or the "Alpine Music" smartphone application (iOS/Android).
