As soon as the switch is activated the front panel screen will display the initializing screen. This
screen shows when DirectStream’s internal “engine” is being loaded with the firmware that
runs DirectStream MK2.
After the initializing screen, you will see the main screen of DirectStream MK2.
The front panel PS logo button, located on the upper left hand corner of the unit, is the Ready/
Operation Mode control for DirectStream MK2. This control has two modes: Ready Mode and
Operational Mode. Ready Mode (Standby) is designed to keep power on to critical internal circuitry,
including power supply capacitors, thermally sensitive semiconductors and integrated circuits.
Press this front panel button to activate the Ready Mode or to place DirectStream MK2 in
Operational Mode. When pressed to activate the Ready Mode, the display as well as the outputs are
turned off, but all the unit’s critical internal circuitry remains active.
If you wish to conserve
energy consumed by
DirectStream MK2 it
will be necessary to
use the rear panel
power switch. Using
this rear panel switch
will remove power
from critical components. In order to gain maximum performance levels, you will need to turn
DirectStream’s power on at least 1 hour before use.
Should DirectStream MK2 need to be rebooted, use the rear panel power switch to power
cycle the instrument. It's best to wait 30 seconds before powering back on.
The DirectStream MK2 features a menu display system that is accessible using the control
ring. It’s a good idea to familiarize yourself with the different functions in the DirectStream
MK2 menu. To access the menu, simply press and hold the menu button to the left of the
display for two seconds. A gear icon will appear in the up-per right corner showing that you
are in the Settings menu.
Executing a long press of the menu button (holding for more than two seconds) will exit
the menus and return the unit to the Home screen. The menus will also timeout after fifteen
seconds. Note that settings are typically saved in real time as the changes are made.
The main display shows the volume by default. Pressing the center, right, or left buttons on
