It's much clearer now, thanks for the responses!
Digital voltage?
Regarding the AES/EBU output, the manual for my Theta Data Basic II transport reads: "...provides the digital standard signal in a balanced configuration and at a higher voltage level." What is the upside/downside of a higher voltage digital level? Would a higher voltage digital output level bump up the analog output level? Are there big 1's and 0's and little ones? :^)
