Hello ThomasD! You can press and hold the SOUND CONTROL button for about 5 seconds to adjust the sound for each frequency band. 150Hz, 300Hz, 600Hz, 1.2kHz, 2.5kHz, 5kHz, and 10kHz are selectable using the Left/Right buttons and each can be adjusted to a setting between -6 to +6 using the Up/Down buttons. (Make sure the Sound mode is set to “STANDARD”.)
Press the CH LEVEL button so you can adjust the volume of each speaker. CENTER LEVEL or TOP LEVEL can be adjusted using the UP/DOWN buttons from -6 to +6.
I hope this tip helps improve your enjoyment. For more help, please call us at 1-800-SAMSUNG (Ask for Soundbars), 8 AM – 12 AM EST, 7 days a week. Live Chat with an agent as well as manuals, software, creating a service ticket, and warranty info can be found at the ‘Support’ link on our Samsung website.
