!

The exclamation point within an equilateral triangle is intended to alert the user to the presence of 

important installation, operation, and service instructions in this manual.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the 

presence of uninsulated dangerous voltages within the enclosure that may be of sufficient magnitude to 

constitute a risk of electrical shock to the user. 

Please read this manual thoroughly before attempting to install, configure, or operate the Stealth PA-1 

Balanced Class-D Monoblock Power Amplifier. After successful installation and configuration of the PA-1 

amplifier, be sure to retain this manual in a safe place for future reference. 
Safety is a key component to a long lasting and trouble free installation. Please read and follow all 

instructions and heed all warnings on the PA-1 amplifier and in this manual. The vast majority of the 

subsequent safety precautions are common sense. If you are not comfortable with the installation of audio/

video entertainment equipment, you should seek the services of a qualified installation professional or call 

us for help.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THE STEALTH PA-1 

AMPLIFIER NEAR WATER OR IN WET LOCATIONS, DO NOT EXPOSE IT TO RAIN OR MOISTURE, DO NOT 

EXPOSE IT TO DRIPPING OR SPLASHING FROM OTHER SOURCES, AND ENSURE THAT NO OBJECTS 

FILLED WITH LIQUIDS (SUCH AS VASES) ARE PLACED ON IT. DOING SO MAY RESULT IN DAMAGE TO 

THE UNIT AND THE RISK OF ELECTRIC SHOCK, WHICH MAY RESULT IN BODILY INJURY OR DEATH.
WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER FROM THE  

STEALTH PA-1 AMPLIFIER. THERE ARE NO USER-SERVICEABLE PARTS INSIDE THE UNIT. REFER ALL 

SERVICE TO QUALIFIED SERVICE PERSONNEL.

Do not install the PA-1 near or above any heat sources such as radiators, heating vents, or other apparatus’ 

that produce heat. Do not block any ventilation openings or heat sinks. Avoid installing the unit directly 

above other heat-producing equipment unless sufficient ventilation or forced-air cooling is provided.
Do not install the PA-1 in locations without proper ventilation. The PA-1 should not be operated on a bed, 

sofa, rug, or similar surface that may block vents. The unit should not be installed in an enclosed location 

such as a bookcase, cabinet, or closed equipment rack unless sufficient forced-air ventilation is provided.
Always install your PA-1according to the manufacturer’s instructions and only use attachments or 

accessories specified by the manufacturer.
Do not install the PA-1 on any stand, shelf, or other piece of furniture that is unable to support its weight. If 

a cart is used to move the unit, use caution to avoid injury from tip-over.
Connect the PA-1 only to power sources of the correct voltage (as shown in this manual and on the PA-1). 
Protect power supply cables from being pinched, walked on, or otherwise damaged. Be especially careful 

where the power cable enters the power outlet and the unit. 
Only connect the PA-1 to an electrical outlet or extension cord of appropriate type and rating. 
DO NOT defeat the safety purpose of a grounding or polarized plug by removing ground pins or using 

unsafe adapters. A polarized plug has two blades - one wider than the other. A grounding plug has a 

third ground prong in addition to the two main conductors. The wide blade or third groundling prong is 

provided for your safety. If the provided plug does not fit your outlet, consult an electrician to replace your 

obsolete outlet. If you replace the power cord, only use one of similar type and equal or greater current 

rating.
The power cable for the PA-1 should be unplugged from the outlet during severe electrical storms, or when 

unused for a long period of time.
