SoundTube - SB335 - 50-Watt per Channel Bluetooth Class D Amplifier

The SB335 is a versatile, small, class D amplifier engineered for use in localized audio applications. Designed for use with SoundTube speakers, other high-fidelity speakers and passive soundbars, the SB335 provides 50 watts per channel into 8 ohms (2 channel operation) or 35 watts per channel into 8 ohms (3 channel operation). Digital and analog inputs are provided, enabling direct connection from most TVs or monitors. Bluetooth® streaming functionality is also featured as a signal option. In addition to the speaker outputs, the SB335 includes a line level subwoofer output. Dolby Digital® decoding is also provided. The SB335 may be controlled via RS232 and will learn IR codes for volume control.

The SB335 is ideal for digital signage, allowing localized amplification of speakers associated with a digital signage display. It is also useful for educational video carts and videoconferencing rollabout carts. The unit's three channel capability and full-range frequency response makes it ideal for powering passive high-quality soundbars such as the Teatro TSB3.0 from SoundTube's sister company Phase Technology.
