The OS-440 is the industry’s first outdoor smart amplifier. The OS-440 can live entirely outside, 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, interface with DLNA servers and even allows wireless multi-zone control. On-board Bluetooth functionality and a WiFi direct mode round out the wireless connectivity options.
