The LS1i links your LS1 system to a PC, Mac or Linux computer via USB. This connection can then be used to control the LS1 and edit its settings. The LS1i USB interface also offers a two channel audio connection from your computer to the LS1 system. Supported sample rates are PCM up to 384 kHz / 24 bits, DSD64 and DSD128.
An extra AES3 digital output facilitates connection to a digital level meter, or to a DAC. The LS1i usage is therefore not limited to just control an LS1 system, but it doubles as a real fine digital audio interface from your computer to a 3rd party DA converter.
