The Balance feature allows you to adjust the center location of the stereo image. Press
down on the control ring to reduce the gain of the right channel, thus making the image
come more from the left channel, and vice-versa. The balance steps are each 1/4dB and
the range is 48 steps each way for a maximum shift of 12dB.
When the balance is set to anything other than the center position, there will be an icon on
the Home screen to indicate this state.
The phase feature allows you to invert the signal from the digital inputs. Use up or down
buttons on the control ring to change the absolute polarity of the signal from “Norm”
(Normal) to “Inv” (Inverted). This can be useful when listening to certain source material that
may have inverted absolute polarity. NOTE: Some listeners are more sensitive to absolute
polarity than others.
This menu display shows the versions of the DirectStream MK2's operating firmware and
FPGA load. If you need to contact our customer service team for help with your unit, please
have this information ready.
*Note: Changing the FPGA firmware version is a separate menu item, located under the
System sub-menu. Up to 10 FPGA versions can be loaded on a USB thumbdrive to be
selected and loaded into the FPGA (these versions will be released over time and must be
downloaded from the PS Audio website when they become available). Select which FPGA
version you wish to use and press the select button. The DirectStream MK2 will show you
the loading steps it uses to activate the new firmware version (each firmware version will
sound different). At the end of the loading process you will be given the option of rebooting
the DAC to load the new version.
