The Dell AX510 SoundBar is only powered from a Dell UltraSharp or Professional series monitor and does not come with a separate power adapter. This stereo soundbar is a good choice for improving the quality of multimedia presentations, online training / Web casts, music listening, gaming, and DVD playback on your system. This lightweight, elegantly designed sound bar can be easily attached to your Dell Flat Panel Monitor. This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system. If your monitor is not a Dell UltraSharp or Professional series monitor, you will need the AX510PA, which comes with a separate power adapter.
