To start using THX tune-up, you'll first have to make sure your home theater (or speakers) and tablet are connected through HDMI or an Apple TV. You can also connect the accessory directly to your tablet with a USB-to-Lightning cable. You also need to download the app, which is free and requires iOS 5.0 or later. Once you have THX tune-up installed and connected, open it and make some moo sounds or listen to Deep Note. There's one calibration bar up top that's fixed at a default setting, but you can move the bar up and down just like you would when calibrating an HDTV. That calibration gives you auto mode. Use your iOS device as a remote and your seat to move up and down the bar to move the colors from top to bottom. You can also use the iOS device as a remote to maneuver the bar but not adjust the color settings.
To calibrate the color of your speakers, hold the ring around the speaker's case and move the bar to the right or left. In auto mode, you can mute or unmute as many stereo speakers as you want. After you have stopped moving the bar, it will reset to the previous settings and you can only adjust the volume on specific speakers.
Figure out which speakers should be calibrated first, or start several at once and then lower the volume on the speakers you want to mute. Once you've mastered your auto mode, THX tune-up features calibrating presets for various color schemes. You can choose one or adjust the color settings yourself. If you're anyone other than a professional, choosing a preset from the Color Scheme drop down menu is the easiest way to calibrate your HDTV. Select a preset from the drop-down menu and adjust the range of color from the color range selector. It's good to adjust the range of colors until you find one that resembles what THX recommends for your HDTV, usually between 2,400 and 5,000.
There's a pretty hard-to-miss slider that lets you cover your speakers with a graduated set of folding speakers for better sound. You can even pull those speakers down to mute them, but that's of little use in most situations. d2c66b5586
