X2.2 Owner’s Manual

For your protection please 

read the following:

Water and moisture:  Electrical devices should not be used near 
water ( as per example, near a bathtub, washbasin, kitchen sink, 
laundry tub, wet basement or swimming pool ).  Care should be 
taken such that objects do not have the opportunity to fall, and that 
liquid is never spilled onto or into the device enclosure through 
openings.

Power Sources:  An electrical device must  be connected to a mains 
power source in strict accordance with the supplied  product owner’s 
manual.  Please verify that the AC mains voltage specified in the 
product manual matches those requirements indicated on the unit 
and the AC voltage provided to your location by the power company.

Grounding:  Adequate precautions should be taken so that the 
grounding provisions built into an electrical product are never 
defeated.

Power Cords:  Pass Laboratories provides a power supply cord that 
meets all legislated requirements for the market in which the product 
was originally sold.  If  you choose to substitute an after-market 
product we urge you to choose one that is fully safety rated by the 
necessary local authority.

Power Cord Protection:  Power supply cords should be routed so 
that they are not likely to be walked on, abraded, or pinched by items 
placed on or against them, paying particular attention to cords where 
they enter plugs or exit from a device.  Never under any circumstance 
insert a cut or damaged power cord into a mains power socket.

Power and Signal:  Cables should never be connected / 
disconnected with equipment powered up.  Failure to heed this 
warning may damage or destroy equipment.

Ventilation:  Power-amplifiers run hot, but you should be able to 
place your hands on them without discomfort.  You must allow for 
this heat in installation, by providing for free air circulation around 
the product.  Electronics should not be subjected to sources of  
excessive radiant heat. Excessive heat can shorten the life of  the 
product and may cause the electronics to self-protect and shut down.

Servicing:  To reduce the risk of  fire, electrical shock or other 
injuries, the user should not attempt to service the device beyond 
that which is described in the operating instructions.  All other 
servicing must be referred to qualified service personnel.
