In the age of smart phones and tablets, it is more important than ever for your entertainment system to be remote and portable. The Polk Ultramarine app is the perfect solution for this problem. The app allows you to control all of the functions of your entertainment system with a simple tap of the screen.

The app works with the following models:

The most popular model, the P1, is the most versatile and has the most advanced functions, but has a small footprint and is the best choice for people who want a smart and handy remote for their entertainment systems. It can also be used as a portable and hand-size controller.

The PA4A and the P1 are similar to the P1, but have a different appearance. The PA4A is the best choice for people who want a sleek and stylish remote for their entertainment systems.

The volume control and the mute function can be accessed by tapping the volume icon in the notification bar.
