Sounds great automatically. Alpine’s Optim6™ PXE-C60-60 is a high-definition digital signal processor (DSP) that takes the complexity out of audio tuning by automatically optimizing your car audio system. This innovative processor eliminates the pain and confusion often associated with DSP tuning by providing automated sound calibration while still offering deep manual control options for enthusiasts.

The PXE-C60-60 features 96kHz/24-bit high-resolution processing to deliver exceptional fidelity, clarity, balance, and impact from your music. Its sophisticated automatic tuning system uses either your iPhone’s built-in microphone or a PC with an external measurement microphone to analyze your vehicle’s acoustic environment and make precise adjustments.
