LS1r remote The beautifully crafted LS1r remote control is part of the LS1 hifi system. It features volume control, source selection and mute, just with one large dial. Two extra digital audio sources can be connected directly to the remote. When placed at a distance, a regular IR remote may be used for wireless control. Every set (except the LS1a) also comes with a USB interface that facilitate connection of a Windows or Mac PC. It can be used to play audio from the computer directly into the LS1. Macs have native support, PCs require a special driver. Via the same USB connection, the LS1 remote software can be used to setup the system.
