ES-LINK Analog overview
Using a current transmission method that utilizes the high-performance of an HCLD buffer circuit, which boasts the ability to supply
strong current at high speed, the effects of impedance on the signal
path are suppressed and transmitting signals purely and powerfully is
possible.
o Ordinary balanced cables (with XLR connectors) are used for
connection. These connectors can only be used with compatible
devices, however, because the transmission format is unique.
