Hello Alfredo Thank you for sharing your experiences with the HW-B63C Soundbar. Make sure that there isn't anything charging near your subwoofer as this can cause interference or static noises. You can optimize your audio performance to your liking by pressing the SOUND MODE button on your soundbar remote, and then selecting the desired sound effect by choosing SURROUND SOUND, BASS BOOST, GAME, ADAPTIVE, DTS VIRTUAL:X, STANDARD. By pressing the TONE CONTROL button, you can adjust the volume of the treble or bass sound. Press the button to select TREBLE or BASS and then adjust the volume between -6~+6 by using the Up/Down buttons. 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”. Additionally, using the WOOFER button on the remote, you can adjust the subwoofer’s volume between -6 to +6 by toggling the button up or down. To set the subwoofer volume level to 0, press the button down.
