Ultimea - Aura S4T Pro 7.1ch Soundbar with 4 Surround Speakers, Subwoofer, App Control, Bluetooth 6.0, HDMI/OPT/AUX, 350W - Black

Hello, Thank you for your interest in our products. Regarding the Aura S4T model, it consists of a soundbar, a subwoofer, and four surround speakers. For placing the two rear surround speakers behind a sofa: Connect the Rear Left Surround speaker [SL] and Rear Right Surround speaker [SR] using the included surround speaker cable. Plug the Rear Right Surround speaker [SR] into a power source. Once the soundbar is powered on, the surround speakers will automatically pair with the soundbar, so there is no need for wired connection to the front soundbar. Additionally, the rear surround speakers and subwoofer connect via the cables included with the system, making setup easy and flexible for placement.

Hello, Thank you for your inquiry. The Aura S4T model supports multiple input types: HDMI eARC/ARC, Optical (OPT), AUX, Bluetooth, and USB (USB is for flash drives up to 128GB only and cannot be used to connect other devices via USB cable). Please note that this model does not support microphone input and is primarily designed for home theater and audio listening, connecting to TVs, smartphones, and other audio devices. Only one input source can be active at a time, so it cannot play HDMI and AUX simultaneously.
