WARNING.  TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE THIS 
APPARATUS TO RAIN OR MOISTURE.    

Clean only with a dry cloth. 

Do not place flammable material on top of or beneath the component.

All PS Audio components require adequate ventilation at all times during operation. Rack 
mounting is acceptable where appropriate. 

Do not remove or bypass the ground pin on the end of the AC cord. This may cause RFI (radio 
frequency interference) to be induced into your playback setup and is potentially unsafe.  All PS 
products ship with a grounding type plug.  If the provided plug does not fit into your outlet, consult 
an electrician for replacement of the obsolete outlet.

Protect the power cord from being walked on or pinched particularly at plugs, convenience 
receptacles, and the point where they exit from the apparatus.  Unplug this apparatus during 
lightning storms or when unused for long periods of time.

When making connections to this or any other component, make sure all components are off. Turn 
off all systems’ power before connecting the PS Audio component to any other component. Make 
sure all cable terminations are of the highest quality.  

There are no user serviceable fuses inside this product.  

THERE ARE NO USER-SERVICEABLE PARTS INSIDE ANY PS AUDIO PRODUCT.  REFER ALL 

SERVICING TO QUALIFIED SERVICE PERSONNEL

Please contact your authorized dealer, distributor, or PS Audio if you have any questions not 
addressed in this reference manual.
