Alpine Imprint Sound Manager 2.1

Eliminated residual DSP noise found in earlier software versions Enhanced Preset Management:

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.

You will execute the "Auto Tuning" routine. The car doors must be closed, engine off, and A/C turned down. The software plays sweeps and chirps through left, right, front, and rear channels. It does this up to 5 times to ensure statistical accuracy. Eliminated residual DSP noise found in earlier software

Even after auto-tuning, you may want more bass. The Sound Manager 2.1 allows you to adjust the parametric EQ after the Imprint correction has been applied. This is the "2.1" advantage—automatic correction with manual musicality. It sounds significantly less bright than the default

Surprisingly, no. For owners of classic Alpine gear (the 9887, 117, or 505), the Imprint processor delivers a warmth and musicality that many modern Chinese Android head units lack. While modern DSPs have 31-band EQs and touch screens, the acoustic algorithm of MultEQ XT (licensed from Audyssey Labs) is remarkably robust. For under $200 used, you get a tuning solution that rivals $800 standalone DSPs in terms of imaging and staging.
