This effectively creates a perception of increased distance for those speakers. Time Correction allows the listener to be placed at an equal distance between the left and right speakers for optimum staging. You can adjust the distance (0-132.7") of each speaker and subwoofer to the listener.
This feature allows you to change the soundstage of your
music in the vehicle. You can select from three modes.
- Front Wide: Creates the effect of widening the front sound field by delaying the sound of the front speakers.
- Rear Wide: Creates the effect of making the front sound image clear and far by delaying the sound of the rear speakers.
- Off: No effect is applied (default)
- Source Volume Level: The output level of each source (Tuner, Disc, USB, iPod, Bluetooth, Pandora, Aux) is individually adjustable from -14 to + 14 dB.
Alpine's TuneIt App: The Apline TuneIt app is an easy-to-use sound-tuning app that also offers Facebook notifications. Download this free app (from Apple's App Store or GooglePlay) onto your Apple iPhone (iOS 6.0+ ) or Android smartphone (2.2+) and create a user profile about your vehicle and sound system. Your iPhone must be connected to the CDE-HD148BT via the appropriate Alpine iPod connector cable (500KCU445I/500KCU471I sold separately) or the Dock-/Lightning-cable that came with your iPhone. Your Android smartphone must support A2DP/AVRCP/SPP Bluetooth profiles and be paired with the Alpine receiver. Your iPhone or Android smartphone will also need an active Data Plan account with connection to the Internet via 3G, EDGE, or WiFi.
- Sound Tuning: The Alpine TuneIt app turns your iPhone or Android smartphone into a sound tuning interface for the CDE-HD148BT. Follow the simple graphical instructions on your phone to adjust sound settings for your specific vehicle or choose from pre-made settings in the database. Settings that can be adjusted include Parametric EQ, Bass Engine SQ, Crossover, and Media Xpander. As you change settings on your smartphone, you will hear the results, so you can customize the sound to exactly how you want it. You can make and save up to 100 different sound settings in your account, which is helpful if you want various settings to use for specific types of music. After tuning your system, upload your settings to the Alpine Cloud Server to share them with other Alpine fans. You can also check out other user's settings and rate them. The more active you are, the higher your profile status progresses within the app.
- Facebook Notifications: The Alpine TuneIt app also keeps you in touch with your Facebook friends. When you receive a notification, you will get a visual alert on the smartphone and the head unit, plus a sound alert through your car speakers. The visual notification includes the Facebook icon and the sender's name, with the profile picture shown on the phone. You are then able to listen to the notification via TTS (Text-to-Speech) through the head unit and your vehicle's speaker. You can even "Like" the notification from the head unit's front-panel controls. In order to receive Facebook notifications on the head unit, the Alpine TuneIt app must be the active app on your smartphone.
Note: Access to the Alpine TuneIt app will depend on the availability of a cellular and/or WiFi network for purposes of allowing your iPhone or smartphone to connect to the Internet. You will also need to turn on the GPS function of your phone.

Variable Color Button Illumination: The head unit lets you choose between Blue, Green, Red, or Amber button illumination. The LCD text will remain white.
Auto Dimmer: This unit is equipped with an illumination lead (orange); when the unit's dimmer mode is set to Auto and the illumination lead is connected to your vehicle's headlight circuit, the display and button illumination will dim to a fixed, preset level whenever the headlights are turned on.

Demo Mode: This unit has a demonstration feature for its display which can be turned On or Off in the menu.
Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input on the rear of the unit that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately).
