Polk VoiceAdjust™- Hear Every Word

Tired of riding the volume control to hear the dialogue during quiet scenes? Have trouble picking out voices when the bass kicks in? Polk’s VoiceAdjust was designed to make sure that you hear every word. This patented technology combines with Signa S4’s dedicated center channel to allow you to raise the volume of only the voices, making them clear and easy-to-understand, while leaving the rest of the soundtrack untouched.

Customisable Sound - Music, Movie, Night Modes

Late night binge-watching session? Don’t worry about waking your family or neighbors. With Night Mode, one button lowers the bass while increasing VoiceAdjust™ so you can hear every word, without raising the master volume. Plus, one-button, preset sound modes optimize the Signa S4 so you can have the best sonic experience for movie watching and music listening.

Deep Effortless Bass

Signa S4’s powerful wireless subwoofer provides the deep, effortless bass that Polk is famous for, at loudness levels that are surprising for its size. Polk's exclusive BassAdjust mode controls bass on both the sound bar and sub ensuring seamless blending. The subwoofer connects automatically on start-up and can be conveniently placed nearly anywhere in the room. Put it up front for maximum impact or try behind the couch to feel the rumble.

Sets Up In Seconds

Set up is easy: simply connect the included HDMI or optical cable (or aux-in on older TVs) for the ultimate sound quality for any TV—even the latest 8K Ultra-HD TVs. Signa S4 is pre-programmed to work with most TV remotes and it quickly pairs to your mobile device via Bluetooth to stream your favorite music. Signa S4’s low-profile design won’t block your TV or your remote. Signa S4 can be wall-mounted for flexible placement.

Rated 5 out of 5 by from Great sound Sounds great, easy to connect to my LGTv. Love that you can change it from music to movie and can increase the dialogue volume.

Rated 5 out of 5 by from Not the most expensive and great sound I replaced my previous Polk sound bar with the S4. What a world of difference between the two! The spatial sound that comes from this bar is amazing. As others mentioned the bass is limited, but it works well enough for me.

Questions

Hi  I am interested in adding additional rear Polk speakers to the Signa s4. Would this be possible to add or could you please advise which ones I could add rear surround speakers to. Many Thanks  Brad

Asked by: Brad001
Hello, As the Signa S4 is a self-contained unit. unfortunately it does not support additional speakers. The SR-2 wireless surround speakers are supported by the following Polk Audio Soundbars; MagniFi 2, MagniFi Mini AX, MagniFi Max AX, and Polk React. Here is a link to the details: MagniFi Series https://www.polkaudio.com/en-us/category/magnifi-series/ React Series https://www.polkaudio.com/en-us/category/react-series/

What is the power output for the S4?

Asked by: Bob308
Hello, and thank you for your question. The power output is not provided as each driver has a dedicated amplifier providing the power needed during playback.

Which sound mode would be used for general TV watching if not watching a movie or listening to music? Night mode?

Asked by: Bob0422
Hello, This is entirely up to you. Each sound mode will change how the sound is output and you may find that you prefer one over the other. Try switching through sound modes and voice adjust modes to see if you prefer one over the others. As reference, Night mode Compresses the dynamic range (difference between loud and soft sounds) to make audio easier to hear at low volumes so you can lower your volume at night and still hear the sound clearly.

Thank you. My CD player has no MIC output. Yes, it does of course have L and R RCA cable AUX OUT jacks. For CD listening, I could switch the SIGNA S4 input to AUX, but with no L and R AUX IN cable connection on the rear of the S4 what would be the point?

Asked by: songman
Hello Songman, A Mic output would not be appropriate for signal transfer, it would have to be a headphone output. In the case that you have a L and R RCA outputs, you can get an adaptor cable such as this to connect to the aux input of the sound bar. While not ideal, it would be a method of connecting a CD player to this sound bar. https://www.amazon.com/Amazon-Basics-Adapter-Subwoofer-Gold-Plated/dp/B01D5H8JW0/?th=1

My tv is hooked to my soundbar using the ARC hdmi port. My Roku 4k device and blu ray player are hooked into the soundbars extra hdmi ports. Since the S4 only has one hdmi port, will it matter if everything else is plugged directly into the tv?

Asked by: Bengi
Hello, As long as the S4 is connected to an HDMI ARC port, then it will be able to receive the audio of any devices connected to the TV's other HDMI ports. If you are having issues with this you can always contact our customer care team for further assistance. https://www.polkaudio.com/en-us/contact-us.html 800-377-7655

I want to enjoy non-Bluetooth music playback from a CD Player through my SIGNA S4's Soundbar. Can I have my Samsung SUHD 700D TV connected to the S4's HDMI Out while having the option of separately listening to CD's using the S4's Optical In?

Asked by: songman
Hello, The Optical and HDMI inputs are both set to the TV input mode and will not be able to be used in this manner. If your CD player has a headphone output or an aux output, then you can connect that to the S4 and switch to the Aux mode whenever you wish to listen to the CD player.

What is the difference between the Signa S4D and the Signa S4?

Asked by: Bengi
Hello, the SD4 is an online exclusive—no sonic differences between the two soundbars. The grill color is slightly different, with the S4D grill adding a touch of grey, and the S4 grill is Black. The S4D does not come with an Optical cable.

I have the Signa 2 which is adequate but not outstanding. What improvements can I count on from the 4?

Asked by: Olfalatumas
Hello, and thank you for your question. The Polk Audio S4 Soundbar adds a dedicated center channel driver, two up-firing drivers, and a larger subwoofer driver. The Bar is also a bit wider, providing a wider soundstage. Soundstage, a more spatial soundstage, and greater impact should be expected.
