Quick guide from the manual

The Insignia 2.1-Channel Wireless Soundbar (NS-HTSB2123) is designed to enhance your TV audio experience. Before using, ensure you have connected the power adapter to the soundbar and placed the subwoofer within 30 feet (10 meters) of the soundbar. The system supports multiple connection types including HDMI ARC, Optical, AUX, USB, and Bluetooth. For the best audio quality, HDMI ARC or Optical connections are recommended.

Connecting your soundbar

Choose one of the following connection methods based on your audio source device:

  • HDMI ARC: Connect an HDMI cable (not included) to the HDMI (ARC) jack on the soundbar and the HDMI IN (ARC) jack on your TV. Ensure your TV's CEC and ARC settings are enabled and the audio output is set to PCM.
  • Digital Optical: Connect the included optical cable to the OPTICAL IN jack on the soundbar and the optical output on your source device. Set the device audio output to PCM.
  • AUX IN: Connect the included 3.5 mm cable to the AUX IN jack on the soundbar and the 3.5 mm jack on your audio source.
  • USB: Plug a USB thumbdrive (WAV or MP3 files) into the USB port. Note that this cannot be used if the soundbar is wall-mounted.

Bluetooth and Subwoofer pairing

Bluetooth: To pair a device, turn on the soundbar, select Bluetooth as the input source (status indicator blinks blue), and search for "NS-HTSB2123" in your device's Bluetooth settings.

Subwoofer: The subwoofer should pair automatically when the soundbar is turned on. If it does not, manually pair by holding the source selector button on the soundbar for three seconds (until the LED blinks turquoise quickly), then press and hold the PAIRING button on the subwoofer for three seconds.

Operation and settings

Use the included remote control to manage your soundbar. Key features include:

  • Sound Modes: Select between Standard, News, and Theater modes. Theater mode activates DTS Virtual:X for an immersive experience.
  • Night Mode: Toggles dialog clarity at low volumes.
  • TruVolume: Provides consistent volume levels.
  • IR Learning: The soundbar can learn button codes from your existing TV remote. Use the Manual or Preset Sequence Learning modes to program the soundbar remote functions onto your TV remote.

Troubleshooting

  • Remote not working: Remove obstacles, replace batteries, or move closer (within 16 ft).
  • No sound/low volume: Ensure the correct source is selected, volume is not muted, and the audio output on your TV is set to PCM.
  • Subwoofer not connecting: Ensure it is within 30 ft of the soundbar and re-pair manually if necessary.
