Thrax Audio Orpheus, Owner'S Manual

Page: 7 / 10

Although most of the front panel controls (Volume, Power, Mute) are self explanatory, Thrax
Audio has outfitted this unit with several advanced features which bear further description:
ON / OFF Button / LED
Switches the unit on and off. See OPERATION SECTION for details.
Mute Button / LED
This button toggles between mute and normal volume modes. When the mute LED is on
the system is muted.
Phase Button
Each button press inverts the phase. The phase setting remains stored for each source.
Source Down Button
Each button press changes the selected source to the next lower source. If this button is
pressed while source 1 is selected the source wraps around to source 3 . The current
source is indicated via a row of LED's between the source buttons.
Source Up Button
Each button press changes the selected source to the next higher source. If this button is
pressed while source 3 is selected the source wraps around to source 1.
Source LED ’ s
A row of 3 LED's between the source buttons. They indicate the selected source number.
The left most LED is source 1 and the right most LED is source 3 .
Green = Normal phase
Red = Inverted phase
NOTE : In some systems switching to an unused input will cause a small amount of hum at
the speakers. This is because with no input connected the signal path is 'hanging in the
breeze' picking up floating by noise .
