Question 1

can i wall mount this polk soundbar? the manual is useless and i don't see brackets.

Accepted Answer

DIAGNOSIS You can wall mount it, but Polk didn't include a bracket. You need a universal soundbar mount that fits its size and weight. FIX First, measure your Signa S2. It's about 35 inches wide. You'll need a universal mount rated for its weight (the S2 is light, so most mounts will handle it). Look for a mount with adjustable arms or a shelf style. The key is finding the mounting points on the soundbar itself: on the bottom, there are two standard threaded inserts (keyhole slots work too). You'll attach the brackets from your mount to those points, then secure the whole assembly to wall studs. IF THAT DIDN'T WORK If you're unsure about drilling into the soundbar, another clean option is to use a floating shelf just wide and deep enough to sit the soundbar on. This gives a mounted look without any modification to the unit. HEADS UP Leave enough space behind the soundbar for all your cables to bend naturally. Crushing the HDMI or power cable against the wall can damage them over time. Also, if you're using the subwoofer, remember it needs to stay on the floor near a power outlet, not mounted.

Question 2

the subwoofer that came with my signa s2 suddenly has no sound. the soundbar works fine.

Accepted Answer

DIAGNOSIS The wireless connection between the soundbar and the subwoofer has been lost. They need to be re-paired. FIX Here's the re-pairing sequence. 1) Unplug the power cords from both the soundbar and the subwoofer. 2) Wait 60 seconds. 3) Plug the subwoofer back in. You'll see its status light glow. 4) Now, plug the soundbar back in. It will automatically search for and pair with the sub. You should hear a low-frequency test tone come from the sub when it connects, and its light will go solid. IF THAT DIDN'T WORK The subwoofer might be too far away or obstructed. Make sure it's within 10 feet of the soundbar and that there's a relatively clear line of sight—thick walls or large metal objects can block the wireless signal. Also, check that the sub's driver (the big circle on the side) isn't physically damaged or punctured. HEADS UP Other wireless devices, like powerful routers or cordless phones operating on the 5.8GHz band, can occasionally interfere. Try moving the router or temporarily turning it off to see if the sub reconnects.

Question 3

the dialogue from movies is really hard to hear, but the music and effects are too loud.

Accepted Answer

DIAGNOSIS This is a common surround sound mixing issue, and your soundbar's 'Night Mode' or 'Dialogue Enhancement' features are probably off. FIX Use your remote. First, press the 'Night Mode' button. The front display will show 'NIGHT' for a few seconds. This compresses the dynamic range, making loud effects quieter and quiet dialogue louder. If that's not enough, press the 'Dolby' button to cycle through sound modes. Stop on 'MOVIE' mode, which is specifically tuned to enhance center-channel dialogue. IF THAT DIDN'T WORK The problem might be your TV's output settings. Go into your TV's audio menu and make sure any "Surround Sound" or "Dolby Digital" output is turned OFF. Force the TV to output stereo (PCM). The soundbar's internal processor will do a better job upmixing stereo to clear dialogue than your TV will with a garbled surround signal. HEADS UP If you're using HDMI-ARC, some TVs have a separate "Digital Audio Out" volume or level setting. Make sure it's set to maximum or 'Variable' so the soundbar is getting a full-strength signal to work with.

Question 4

how do i connect my phone via bluetooth to the signa s2? i can't find the button.

Accepted Answer

DIAGNOSIS You're looking for a physical button, but the Bluetooth pairing is activated from the remote. FIX Grab the soundbar remote. Press and hold the 'Bluetooth' button (it has the Bluetooth symbol on it) for about three to five seconds. You'll see the front LED display start flashing 'BT' in blue. Now, on your phone, go to Bluetooth settings and look for "Polk Signa S2" in the list of available devices. Select it to pair. Once connected, the soundbar will show a solid blue 'BT' light. IF THAT DIDN'T WORK If the soundbar doesn't show up on your phone, it might already be paired to another device. From the soundbar remote, press the 'Source' button until you cycle to 'BT'. If it connects to an old device automatically, you need to clear that pairing first. With the soundbar in BT mode, press and hold the 'Bluetooth' button again for about 10 seconds until the light flashes rapidly—this clears all pairings. Then start the process over. HEADS UP The soundbar can only remember one paired device at a time. If you pair a new phone, it forgets the old one. You'll have to re-pair if you want to switch back.

Question 5

the remote for my polk soundbar stopped working. i changed the batteries, no luck.

Accepted Answer

DIAGNOSIS The infrared (IR) sensor on the soundbar might be blocked, or less commonly, the remote itself has failed. FIX First, clear the line of sight. Make sure nothing—like a game console, decorative item, or even the TV's own base—is sitting directly in front of the soundbar's right side where the tiny IR sensor window is. Dust it off with a dry cloth. Then, test the remote up close. Point it directly at the sensor from about a foot away and press a button. If it works up close, something was blocking the signal. IF THAT DIDN'T WORK Test if it's the remote. Use your smartphone's camera (the selfie camera usually works). Point the remote's IR emitter (the little bulb at the front) at your phone camera and press a button. You should see a faint purple light flashing on your phone screen. No light means the remote is dead. HEADS UP Universal remotes or TV remote control setups (like HDMI-CEC) can sometimes interfere. Try turning off CEC control on your TV temporarily to see if the Polk remote starts working again.

Question 6

my signa s2 makes a constant low humming or buzzing sound, even when nothing's playing.

Accepted Answer

DIAGNOSIS That's a ground loop or electrical interference, usually coming through the connection with your TV. FIX The most common fix is to isolate the audio connection. If you're using the HDMI-ARC connection, unplug it and switch to the included optical cable. Optical cables transmit light, not electricity, so they can't carry a ground hum. Set your TV audio output to optical and set the soundbar source to 'OPT'. The hum should disappear immediately if that was the cause. IF THAT DIDN'T WORK If you're already on optical or the hum persists, try plugging the soundbar's power adapter into a different outlet, preferably one on a different circuit than your TV and other gear. Sometimes power conditioners on the same circuit can cause noise. HEADS UP Don't ignore a loud, sharp buzzing—that can indicate a failing component inside the soundbar. A low, steady hum is almost always a connection/power issue, not a hardware failure.

Question 7

the soundbar turns on but there's no sound from my tv. the optical cable is connected.

Accepted Answer

DIAGNOSIS Your TV's audio output setting is probably still set to its internal speakers instead of optical out. FIX You need to change two settings. First, on your TV remote, go into the audio or sound settings menu. Look for "Audio Output" or "Speaker Selection." Change it from "TV Speakers" to "Optical" or "Digital Audio Out." Second, grab your soundbar remote. Press the 'Source' button until the white LED on the front shows 'OPT' for optical. That should get you sound. IF THAT DIDN'T WORK The optical cable might be bad or not fully seated. Unplug it from both ends and plug it back in firmly—you should hear/feel a click. Try a different optical cable if you have one. Also, check that the plastic protective cap was removed from the cable ends. HEADS UP Some TVs require you to change the audio format in a separate menu. If sound is still missing or is choppy, look for a setting called "Digital Audio Format" and switch it from "Auto" or "Bitstream" to "PCM." That usually solves compatibility hiccups.

Question 8

my polk signa s2 soundbar won't turn on at all, no lights, nothing. it's plugged in.

Accepted Answer

DIAGNOSIS This is almost always a power supply issue. The internal power adapter or the connection to it has failed. FIX First, check the basics. 1) Make sure the wall outlet works by plugging in something else. 2) Trace the power cable from the soundbar to the small black power adapter brick. 3) Check that the cable is fully plugged into both the brick and the soundbar. If it all looks connected, the adapter itself is likely dead and needs to be replaced. Polk doesn't sell it separately, but you can find a universal 12V DC adapter that matches the specs (center-positive polarity, 12V, at least 3A). IF THAT DIDN'T WORK If a new adapter doesn't fix it, the problem is inside the soundbar, likely on the main board where the power connects. At that point, repair isn't really practical for most folks. HEADS UP Never force the DC plug into the soundbar's port. It only fits one way, and forcing it can damage the internal power jack, which is a much harder fix than swapping an external adapter.
