Alpine Imprint Sound Manager 2.1.0.0 (Latest) The Issue / The Fix Alpine Imprint Sound Manager 2.1
The software kept losing connection to the PXA-H800. Fix: Do not use a USB 3.0 (blue) port. Force the Alpine driver to use a USB 2.0 port or a USB 2.0 hub. Also, disable USB selective suspend in Windows Power Options. Thanks
The new "Target Curve Library" is a huge upgrade. I stopped using the standard "Flat" or "Reference" curves. Instead, I imported the JBL "Harman Target" curve (flat with a 6dB downward slope from 20Hz to 20kHz). It sounds significantly less bright than the default Alpine curve.
