Alpine Imprint Sound Manager 21 -

The Alpine IMPRINT Sound Manager 2.1 is a legacy PC application used to tune and calibrate Alpine car audio systems that utilize "IMPRINT" technology. It is primarily associated with the KTX-H100 calibration kit and the PXA-H100 processor. Core Functionality

1. Open the "Routing" Page: Assign which input (e.g., Front Left) goes to which output (e.g., Tweeter Left).
2. Set Crossovers: Choose Linkwitz-Riley or Butterworth slopes (6dB to -48dB/oct).
3. Run Imprint Auto-Tuning: Connect the microphone. Let the computer measure the 21-band response.
4. Manual EQ (The '21' step): Open the Parametric EQ panel. You will see the auto-curve. Now, drag the Q to narrow or wide. Add a 3dB shelf at 10kHz for air. Cut 200Hz by 4dB to remove muddiness.
5. Phase Adjustment: Use the all-pass filter (APF) to align the tweeter and midrange at the crossover point without moving physical speaker locations.
