Aura A40 7.1ch Virtual Surround Soundbar with Subwoofer — 4 Surround Speakers, 330W Peak, Opt/AUX/BT, App Control

The Aura A40 is a 7.1ch virtual surround soundbar with a dedicated subwoofer and Peak Power 330W. It offers Optical, AUX and Bluetooth (Opt/AUX/BT) connectivity and can be managed from the Home.smart App, which provides multiple EQ modes, band adjustments and matrix tuning. OTA firmware updates are supported to keep the Ulitmea 7.1 virtual surround sound system for TV up to date. Speaker wiring and pairing: Connect the soundbar to the two front surround speakers using the front surround cables (FR & FL). Use the rear surround cable for the two rear surround speakers; power the rear right surround speaker so it can pair wirelessly with the soundbar. If pairing does not happen automatically, press and hold the SURROUND button on the remote for 5s until "SUR" flashes, then press and hold the PAIR button on the rear right speaker for 5s until its light flashes. Once pairing is successful, the indicator light will stay on. Surround performance and tuning: The system includes 2 front and 2 rear surround speakers for accurate front-to-back sound projection and a more immersive soundstage. There are 13 adjustable surround levels to tailor spatial effects, and the wireless rear-link reduces cable run and improves placement flexibility.
