Hi Mark, Thank you for taking a few moments to review the Samsung HW-C47M Soundbar. If you would like louder (or softer) bass from your subwoofer, you can adjust the level by rocking the WOOFER button on the soundbar remote, and then adjusting the level from -6 to +6. To set the subwoofer volume level to 0, press the button in. You can adjust the Treble and Bass by pressing the TONE CONTROL button then use the UP/DOWN buttons to change the levels between -6 to +6. For precise audio adjustments, you can use the 7-band frequency equalizer to optimize the sound for your room acoustics by pressing and holding the SOUND CONTROL button for about 5 seconds, make sure you also set the SOUND MODE to STANDARD. If you need more help, Samsung is here for you. Please call us at 1-800-SAMSUNG, 8AM - 12AM EST (Ask for Soundbars), 7 days a week.

Hello WalmartCustomer, We appreciate you taking a moment to review the Samsung HW-C47M Soundbar. When powered on for the first time, the rear speakers and subwoofer should automatically connect wirelessly. If the auto-connection process fails, you can try manually connecting the rears to the soundbar. To setup the wireless rear speaker kit included with the soundbar, first use the color-coded speaker wires to connect the rear speakers to its wireless module and place these three in the back of your room. Plug the wireless receiver module power cord into an electrical outlet and into the wireless receiver module to turn on the wireless receiver module. Press and hold the ID SET button on the back of the wireless module for at least 5 seconds or until the blue light starts blinking. Turn off your soundbar and press the Up button on the remote for 5 seconds. The ID SET message will appear on the soundbar for a short time and then disappear. After the ID SET process, the soundbar power is automatically turned on. The LINK LED indicator stops blinking and glows a solid blue when a connection is established between the soundbar and the wireless receiver module. In addition to adjusting the settings through the soundbar, you may want to try checking the sound format on your TV to ensure you are getting the best experience for a surround sound setup. If your Digital Output Audio Format is set to PCM then you will likely notice decreased performance with surround sound audio systems. Dolby options are designed for surround systems (like 3.1.2 or 7.1), whereas PCM provides great sound quality for stereo speakers. On a Samsung TV this setting can be found at Home > Settings > Sound > Expert Settings. (It can also be found in the Quick Settings.) If you need more help, Samsung is here for you.
