The industry's first outdoor smart amplifier.

Your smart home deserves a smart yard. The OS-440 is an outdoor amplifier, allowing unprecedented freedom when designing outdoor audio systems. Without being tethered to the house, the OS-440 can wirelessly connect to the home's network and function as a certified Google Chromecast device, interfaces with DLNA servers, and has multi-zone wireless control.

On-board Bluetooth functionality and a closed, stand-alone WiFi direct mode round out the wireless connectivity options of the OS-440. Hard-wiring sources are also an option with analog and digital inputs, allowing the OS-440 to interface with any system or source already in the home.


  • Tri-band Bluetooth and WiFi antennas ensure strong, consistent wireless performance
  • Control source selection from the unit, or from the MSE-OS App. Choose from Analog, Optical, WiFi, or Bluetooth
  • Digital and RCA source inputs make the OS-440 fully compatible with any equipment you already have
  • 4-channels x 40W, or bridgeable into 2 x 80W. Power your entire backyard audio system

Note: The OS-440 is designed to operate in humid, outdoor conditions. Do not place the OS-440 in a location where it is exposed to prolonged direct sunlight, precipitation, or where it may come in contact with water. The ideal location for an OS-440 is inside a cabinet. The OS-440 is not waterproof. If you do not have a dry, protected spot for the OS-440, we recommend using a weatherproof box to mount the amp onto an exterior wall.
