Auto EQ
* To use this function on a device other than the iPhone, an external microphone (KTXCSP1) is required.

Auto Anti EQ

• It is usable when Hi.Level is selected for Main source.
• Insert a USB storage into your audio device and play the sweep signal file.
• * The sweep signal file can be downloaded from the Alpine website.

Volume Adjustment

• Place the microphone in the middle of your car, about 30 cm (1 foot) from the center console. Then, click the button to proceed.
• A sweep sound will be played at a low volume. Using the on-screen volume slider, gradually increase the volume until the input level is close to the center of the volume monitor.
• Once a good level is detected for a few seconds, the signal playing will automatically stop.
• Once the level adjustment is complete, you will be prompted to proceed to the next step (measurement).

Measurement

Microphone movement
Correct microphone movement during sound measurement is critical to setting a good result from Auto EQ. Please read this section carefully.

1. Overview
   • To make a measurement, you will move the microphone through the space of the cabin while Auto EQ plays a frequency sweep (“whoop-whoop” sound).
   • The key is to move the microphone constantly and consistently so that all of the space in the cabin is evenly covered during measurement.
   • This is important, so we will explain it in detail.
2. Measurement points
   • One AutoEQ measurement consists of at least 200 measurement points. That is, the frequency sweep (“whoop-whoop”) will be played 200 times in order to measure the cabin’s sound.
   • The exact point in space where the microphone is when it hears one frequency sweep is a measurement point. The sound was measured at that point.
   • The goal of microphone movement is to space these measurement points as evenly as possible in the frontal space of the car cabin.
3. Range of movement
   Spaces through which you should move the microphone include:
   • The space above the dashboard.
   • The space in front of the driver and passenger, as low as the front of their shins (going slightly into the foot wells) and as high as the ceiling.
4. What to avoid
   When moving the microphone for a measurement:
   • Do not stop moving the microphone at all, including for individual measurement points.
   • Do not go deep into the foot well spaces in the measurement.

Perform measurement

• When you are ready, touch the button to begin measurement.
• A countdown will begin on the screen, and then the measurement process will begin. For the duration of the measurement, move the microphone through the cabin of the car as described in the previous section.
• During measurement, the result of each sweep will be displayed on the screen with a faint curve and the average will be shown with a strong curve.
• The progress of the entiremeasurement will be shown in a progress bar at the bottom of the screen.
• The app will confirm when measurement is completed.
• If you see no obvious problems with the measurement, you can accept it. If not, choose “remeasure” to retry measurement.

Tuning
With measurement complete, you are ready to tune the sound in the vehicle.

Tuning screen
This section is an introduction to the tuning screen. Figure 6. It will cover the controls shown on the screen without discussing procedure.

1. Side Panel Controls
   These are the controls available outside of the main graph area:
   • Center Stage Mode
     This is used to recall driver-specific Center Stage Mode settings.
   • EQ Gain Offset
     This setting adjusts the boost and cut of the EQ. This will be the first step in your tuning process.
   • Reset to Default
     This button resets everything on this tuning screen to defaults.
   • Bypass EQ
     This toggle allows you to A/B test the sound with the EQ on and off.
   • Level
     This slider controls the volume of the music source.
   • Store / Recall
     This allows you to save the adjusted target curve or recall the saved target curve.
2. Graph Curves
   These are the curves shown in the main graph area. The display of each one can be toggled on and off.
   • Target (yellow)
     This is the curve which you will manipulate to tune the system. AutoEQ will match your system’s sound to this curve.
   • Measurement (dark teal)
     This is the measured APVD of your car’s system.
   • EQ (blue)
     This is the correction curve AutoEQ will apply in order to achieve your target curve.
   • Predicted (gray)
     This curve shows what the predicted result from your target curve will be. It will vary slightly from the target (yellow) curve, or may be hidden behind it if AutoEQ is going to hit your target exactly.
     Distortion & Noise (magenta) – This curve shows the distortion and noise that were present during your measurement.

Tuning Process

This section covers the standard procedure using the tuning screen to create your EQ.

1. Play reference audio
   You can play audio while tuning. You can make tuning in real time while playing audio from the device selected as Main source.
2. Adjust the Target Curve
   • Enable the display of the Target curve.
     (Displaying other curves is optional.) This is the yellow curve with control points which you can set to define your desired outcome. Each control point is represented as a node (white dot) on the curve.
   • Moving the control points
     To move a control point, simply drag it to the desired location. You can move it side to side or up and down.
   • Adding a control point
     To add a control point, double-tap on the Target curve where you want to create the new point. Then, drag that point to adjust its position.
   • Deleting a control point
     To delete a control point, double-top on it. You will have an option to delete that control point, or to cancel deletion.
     As you modify the target curve, AutoEQ will update the EQ curve and send it to the amp so you can hear your result. There is a delay of a few seconds from when you make an adjustment to when you hear it from the system.
3. Storing the EQ Curve
   • After adjusting the target curve, touch the [Store/Recall] button to call up the preset screen.
   • Touch the [Store] button and select T-Curve1/2/3 to save the current target curve data.
   • Touch the [Recall] button and select T-Curve1/2/3/Default to call the target curve data stored in it.

Center Stage Mode setting
In this mode, adjust the sound stage to the center of the car instead of in front of the driver.

* This setting is dedicated only for the driver seat. Sound balance is lost at  non-driver seats.

• Center Stage Mode
  This toggle allows you to turn Center Stage Mode ON/OFF.
• Steering Wheel Position
  Select the Steering Wheel position.
• Micro adjustment
  Adjust the Stage position left or right.

FAQ

Q: Where can I download firmware update files?
