Automatically Switches From The Main Audio System To A Local Source

Provide an easy way to listen to high-quality audio and switch from one audio source to another with the Russound Digital Amplifier, 2-Channel. This amplifier is specifically designed to automatically switch between a default source from a whole-home audio system to a local source such as a television or PC located in a bedroom. For example, when a television is turned on in the bedroom the amplifier will automatically switch the room's speakers to its own output so you can hear audio from the television instead of the audio from your whole-home audio system. It can also be used as a single-source two-channel zone amplifier for any zone in your home. The D25-LS Amplifier can be mounted on a wall or in a rack as a single unit or rack mounted side by side within a 1U space next to a second D250LS 2-Channel Digital Amplifier.

  • 2-channel amplifier can switch from whole-home audio system to local source
  • 50 watts per channel into 8 ohms, 75 watts per channel into 4 ohms and bridgeable to 150 watts at 8 ohms
  • Small 1U design takes up a half-rack space
  • Built with robust circuitry for long-lasting stability
  • Can be wall mounted or installed in a rack (1U space)

Rated at 50 watts per channel into 8 ohms and 75 watts per channel into 4 ohms, the D250LS Amplifier can be set in bridge mode, which will make it rated at 150 watts of power into a single 8 ohm load for louder and cleaner sound. Each output channel of the amplifier is designed with robust thermal and short circuit protection so it can perform safely and reliably under extreme conditions.
