Polk Audio Signa S4 Soundbar System

Polk Audio Signa S4 Soundbar System

Polk Audio Signa S4 is a 3.1.2-channel soundbar system with a powered wireless subwoofer.

The soundbar contains 7 drivers. Two upward-firing drivers reproduce Dolby Atmos height channels, while a dedicated centre driver handles dialogue. Non-Atmos content can also be processed for a virtual surround presentation.

VoiceAdjust increases speech independently. BassAdjust controls bass in both the soundbar and subwoofer so their low-frequency presentation can be adjusted together.

Connect a TV through HDMI eARC/ARC or optical, or use the analogue 3.5 mm input for an older device. The subwoofer pairs automatically. Wireless carries the audio signal, while both components still require mains power.

Main Features

• Dedicated height-channel drivers add overhead Atmos effects to film soundtracks.
• Movie and Music presets select processing for films or music with one button.
• Night mode lowers bass and emphasises dialogue for listening at a lower overall volume.
• Bluetooth 5.0 streams music from a phone or tablet, with SBC support for standard wireless playback.
• The 60 mm-high soundbar can sit in front of a TV or be mounted on the wall.
• The system is pre-programmed for many TV remotes, often allowing daily volume control with a single remote.
