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.
