Quick Start Guide 

 

 

phono or equalized input of any type.

Once everything has been connected, use a high quality AC cable to power DirectStream.  
DACs in particular are quite sensitive to AC power and produce a bit of line noise 
themselves.  Make sure you have a high quality shielded power cable to power 
DirectStream, and a Power Plant if possible.  

PS Audio produces an entire line of high quality shielded power cables that are generally 
accepted as being some of the best in the industry.  Whatever you choose, make sure it 
honors the music.

Turn the AC power switch in the rear of DirectStream to the ON position.  The power switch 
is located just above the AC inlet.

As soon as the switch is activated the front panel touch screen will display the initializing 
screen.  This screen shows when DirectStream’s internal “engine” is being loaded with the 
fi rmware that runs DirectStream.

After the initializing screen, you will see the main screen of DirectStream.

The front panel PS logo button, located on the upper left hand corner of the unit, is the Ready/
Operation Mode control for DirectStream. 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 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 it 
will be necessary to use the rear panel power switch.  Using this rear panel switch will remove 
power from critical components and in order to gain maximum performance levels you will need
