CAUTION
RISK OFELECTRIC SHOCK
DO NOTOPEN
The symbol is used to indicate that some hazardous live terminals are involved within this apparatus,
even under the normal operating conditions.
The symbol is used in the service documentation
to indicate that a specific component shall be only
replaced by the component specified in that documentation for safety reasons.
Protective grounding terminal.
Alternating current /voltage.
Hazardous live terminal.
ON: Denotes the apparatus is turned on.
OFF: Denotes the apparatus is turned off, because it uses
the single pole switch, be sure to unplug the AC power to
prevent any electric shock before you proceed with your
service.
WARNING: Describes precautions that should be
observed to prevent the danger of injury or death to
the user.
CAUTION: Describes precautions that should be
observed to prevent danger of the apparatus.
WARNING
Power Supply
Ensures the source voltage matches the voltage of the
power supply before turning ON the apparatus.
Unplug this apparatus during lightning storms or when
unused for long periods of time.
External Connection
The external wiring connected to the output hazardous
live terminals requires installation by an instructed person,
or the use of ready-made leads or cords.
Do not Remove any Cover
There are maybe some areas with high voltages inside,
to reduce the risk of electric shock, do not remove any
cover if the power supply is connected.
The cover should be removed by qualified personnel
only.
No user serviceable parts inside.
Fuse
To prevent a fire, make sure to use fuses with specified
standard (current, voltage, type). Do not use a different
fuse or short circuit the fuse holder.
Before replacing the fuse, turn OFF the apparatus and
dis-connect the power source.
Protective Grounding
Make sure to connect the protective grounding to prevent
any electric shock before turning ON the apparatus.
Never cut off the internal or external protective grounding
wire or disconnect the wiring of protective grounding terminal.
Operating Conditions
This apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as
vases, shall be placed on this apparatus.
To reduce the risk of fire or electric shock, do not expose
this apparatus to rain or moisture.
Do not use this apparatus near water.
Install in accordance with the manufacturer's instructions.
Do not install near any heat sources such as radiators,
heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
Do not block any ventilation openings.
No naked flame sources, such as lighted candles, should
be placed on the apparatus.
IMPORTANT SAFETY INSTRUCTIONS
Read these instructions.
Follow all instructions.
Keep these instructions.
Heed all warnings.
Only use attachments/accessories specified by the manufacturer.
Power Cord and Plug

grounding type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug
has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety.
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 the plug, convenience receptacles, and
the point where they exit from the apparatus.
Cleaning
When the apparatus needs a cleaning, you can blow off
dust from the apparatus with a blower or clean with a rag
etc. Don't use solvents such as benzol, alcohol, or other
fluids with very strong volatility and flammability for cleaning
the apparatus body.

1. XA500/1000
The XXL XA series is a line of high power, low profile, professional Power Amplifiers with advanced features and
great reliability. They deliver tremendous power in only two rack spaces, providing high level performance under the
most demanding conditions. An automatic speed fan matches cooling capacity with heat requirements. The amplifier
frame contains all solid-state circuitry, using complementary silicon output devices. The amplifier is supplied with a single
moulded AC cord having an appropriate AC plug for the intended operating voltage. The amplifier employs forced air
cooling with a variable speed fan for minimum acoustic noise. Air flow is from rear to front to avoid temperature rise
inside the Rack. The amplifier contains two independent channels, with separate AC transformer secondaries, power
supplies and protection system. All protection systems, except the main AC one, are self resetting upon removal of fault,
and the remaining channel shall continue to operate. Each channel has independent protective circuitry against open
circuit, short circuit, mismatched loads and over temperature. Each channel has also a main LED that becomes green
for power-on indicator and red for muting or protection, another red LED that shows true amplifier clipping and a yellow
one for the Limiter stage. The power outputs employ standard power connectors. All the inputs are electronically balanced
and an high quality audio transformer can be added on the input stage of each channel.
