Alpine TuneIt App

TuneIt App

The Alpine TuneIt App is an easy-to-use sound-tuning app that also offers Facebook notifications. Download the free app or the Alpine TuneIt App with TTS app onto your iPhone or Android smartphone and create a user profile about your vehicle and Alpine sound system. Follow the simple graphical instructions 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, Crossover, and Media Xpander. 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. Share your settings and get rated on your tuning skills, plus try out and rate settings made by others. The more active you are, the higher your profile status progresses within the app.

Now in its second generation, new features added to Alpine TuneIt App include increased vehicle choices for easier profile set-up, an expanded database of Alpine speakers and subwoofers for more precise sound system tuning and Bass Engine SQ tuning to tailor the in-vehicle bass characteristics.

Bass Engine SQ: Bring Balance to Your Music

Use the Bass button on the faceplate or the Alpine TuneIt App to get the best tonal balance and efficient power distribution to all (front, rear, and sub) speakers independently. Bass Engine SQ tuning provides tonal balance by automatically adjusting different combinations of EQ, Sub Level and Crossover settings through the choice of five bass profiles (Standard, Punch, Rich, Mid Bass, Low Bass).

Microphone IncludedThis unit comes with all that’s needed for Bluetooth convenience. The UTE-52BT comes with a tuned microphone that’s engineered to reduce noise interference and feedback. This allows optimal placement in your car, for the best possible sound quality.

Making, Taking Calls & Call Waiting

Making and taking phone calls has never been more convenient. You can set up your cell phone/head unit to automatically answer your calls. Use the supplied microphone to speak, and then listen through your car’s speakers. When a call comes in, your music mutes to carry the phone call. View caller information including Caller ID, Missed, Dialed, and Received calls right from the head unit display. If you receive a second call, you can have the first caller wait momentarily by pressing “2” for call waiting mode. Once both calls are finished, the mute for music is deactivated. This truly makes the transition from your phone calls to music enjoyable and convenient. You can even use the UTE-52BT’s preset buttons to quickly jump through your phone book, making navigation through large phone books much faster.

Hands-Free Calling Sound Customization

To bring sound balance to your hands-free experience, you can adjust the UTE-52BT’s mic gain, phone output and ringtone volume. If that’s not enough, there are five sound quality settings to choose from to get the balance just right for you. This flexibility will make your phone calls a pleasurable experience.

Steering Wheel Control

If your car has factory Bluetooth steering wheel controls, then it will also control your new UTE-52BT’s built-in Bluetooth. Or, control your head unit right from your factory installed steering wheel controls by adding a third party adapter. Use an adapter from popular brand names such as Axxess or PAC to add this feature.
