The Tango TRX app allows you to customize your listening experience with a five band equalizer with music genre presets - pop, rock, rap, jazz or flat. And for you audiophiles, you can customize the EQ right on screen with a simple slide of a finger. Use your Tango TRX app to wirelessly control your unit from your iPod touch, iPhone or iPad. This app allows you to navigate iPod controls with album artwork as you would on your device. It also gives you a direct replica of the full function remote for controlling track, volume, power, bass and treble right from your device.
