The analog Line Output bypasses the headphone amplifier,
and provides the best possible sound quality for connection
to the line level inputs on preamps, pre/pros, external
headphone amplifiers, and powered monitors that have
their own volume controls.
Toslink
Digital Input
The Toslink digital output carries a S/PDIF version of the
digital audio at the input, which can be routed to another
DAC or a digital input on a pre/pro or AVR. Pressing the
Output Select Switch toggles between the analog and
digital outputs on your Big Ego, and the Output Indicator is
lit green when the Toslink digital output is selected.
