With HARMAN Volume you can set your desired volume between low, medium and high. You can listen to your audio without sudden distracting changes such as blasts from ads, and volume variations as you switch between channels on your TV. Other benefits include full sound effects even at low volumes, this means if you are watching movies (DVD, BlueRay disc) and HARMAN volume is set to low volume, then the signal is more compressed, than what the other volume levels is. This will allow you to hear natural, consistent sound at low volume level, and not only hearing voice conversation from movies, giving you the same movie experience just with lower volume. What is best for you is a matter of personal preference, so we recommend playing around with the three different levels.
