Прочие устройства — SVEN SB-2700DA

The SVEN SB-2700DA is a soundbar with a wireless subwoofer that supports Dolby Atmos decoding for television, film and games. The bar holds seven drivers, the subwoofer sits in a wooden MDF cabinet, and the two link wirelessly, so only a mains cable is needed at the subwoofer position. SVEN describes the result as virtual surround from a single bar in front of the viewer.

Key specs that matter

Total output is 450 W, made up of 275 W for the subwoofer and 7 x 25 W for the soundbar. The bar covers 150 Hz to 20,000 Hz, and the subwoofer handles 40 Hz to 150 Hz. The bar uses seven 48 mm (2 inch) drivers, and the subwoofer carries a single 148 mm (6.5 inch) unit. Inputs are HDMI eARC, optical, a 3.5 mm AUX socket and Bluetooth. The soundbar measures 1000 x 66 x 96 mm and the subwoofer 239 x 368 x 241 mm, with a combined weight of 7.5 kg. Both units run from 230 V at 50 Hz, and each draws a rated current of 0.04 A. The subwoofer's bass range begins at the point where the bar's range ends, so the crossover between the two units falls at 150 Hz.

Engineering and use context

The HDMI eARC connection carries the TV's audio back to the bar and supports HDMI CEC, so the television remote can control volume and power, although SVEN notes this may behave differently depending on the TV brand. On first power-up the bar and subwoofer pair automatically, and an indicator on the subwoofer turns from blinking to steady once the link is made. A PAIR button on the subwoofer and a long press of SOURCE allow manual pairing if needed. The supplied infrared remote has dedicated keys for Dolby Atmos, a MOVIE mode and a SOUND MODE button cycling MOVIE, MUSIC and NEWS equalizer settings, plus bass up and down. The top panel carries power, source and volume buttons, and an LED display shows the current state. A USB port on the bar is reserved for software updates. The box includes the remote with two AAA batteries, a 150 cm HDMI cable, a 150 cm analogue signal cable, two mains cables and a wall-mounting kit with a guide.

Pairing

A TV with an eARC or ARC HDMI port is the intended partner, with the optical socket as a fallback for older sets. The subwoofer radiates non-directional bass, so it can go anywhere in the room near a power outlet. The remote works at up to 7 m and within a 30 degree angle of the infrared receiver on the subwoofer, and the bar can be hung on the wall beneath the screen. Phones and laptops connect over Bluetooth or the analogue input for music.
