What is the difference between the “SoundBridge” and the “SoundBridge Radio”?
The SoundBridge is designed to connect to your existing Stereo or Powered Speakers, and so is less expensive. The SoundBridge Radio has self-contained high quality speakers and subwoofer. The SoundBridge Radio also has buttons on the unit that can control it, and adds additional features like AM/FM radio, a headphone jack, and an SD card slot. All SoundBridges run similar software, and most have VFD displays. However, resolution of the display varies by model number. For more information, see this page.
