The D250LS is a 2-channel amplifier with automatic switching and a space-saving low-profile design.
The D250LS is perfect for installations that include adding a local source to a multiroom system. The D250LS allows the source (e.g., a PC or TV in the bedroom) to automatically override the audio playing in that particular room of a distributed audio system. When the local source is turned on, the amplifier switches the room speakers to its own output. This amplifier also provides autosensing line and amplified inputs as well as a trigger input for versatility in different applications.
The D250LS is rated at 50 watts per channel into 8 ohms and 75watts per channel into 4 ohms. In bridged mode the D250LS is rated at 150 watts of power into a single 8-ohm load. Each amplifier output channel incorporates robust protection circuitry for safety and reliability under extreme circumstances.
The D250LS is also perfect C-Series installations, specifically the MCA-C5, The MCA-C5 on zones 7 & 8 features line level outputs only + 12v triggers for remote power on/off zonal commands. The D250LS can be mounted side by side in a 19" rack - so they offer excellent flexibility for multi-room controllers that require outboard amplification.
Comes with rack assembly kit and screws.
