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
Do not defeat the safety purpose of the polarized or
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.
Clean only with a dry cloth.
Servicing
Refer all servicing to qualified personnel. To reduce the
risk of electric shock, do not perform any servicing other
than that contained in the operating instructions unless
you are qualified to do so.
Servicing is required when the apparatus has been damaged in any way, such as the power supply cord or plug
is damaged, liquid has been spilled or objects have fallen
into the apparatus, the apparatus has been exposed to
rain or moisture, does not operate normally, or has been
dropped.

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.
2.

Power Source Socket
It is used to connect power cord, after setting the proper voltage, connect one end of power cord with the unit
and another end with mains.
Manual Reset Pushing-Button
8
This switch works as fuse for protecting the unit from damage. When the unit is overloaded or the temperature
inside the unit is too high, this pushing-button will spring up and break the power supply. The power supply will
be restored with pushing this switch down again.
Output Connector
9
These connectors have two kinds: Binding post and Neutrik connector. You can choose proper connectors
according to practical need. For your safety, please be careful when do connecting work.
Clip Switch
10
Set this switch at "ON" position, once the output level is above maximum output level, the clip begin, thus keeping
consistent output level for protecting apparatus. If the switch is set at "OFF", this clip function doesn't work.
Balanced Input Connector
11
These connectors connect the input signal of channel1 and channel 2 separately.
Balanced Output Connector
12
These two output connectors are paralleled inside with input connectors. It enables the unit work under
paralleled mode. Please also refer to wiring diagram for paralleled mode.
13
Mode Selector
Total two optional modes: Up for Stereo mode; Down for Bridge mode.
- Stereo
In this mode, Channel 1 and Channel 2 operate independently ( just as traditional stereo amplifier). The signal
input into channel 1 can be output from channel 1 only, similarly, the signal input into channel 2 can be output
from channel 2 only.
You can also operate the paralleled mode via outside wiring, so, the signal input from channel 1 or 2 will be output
from both channel 1 and 2 simultaneously. Details refer to the chapter 4.
- Bridge
In this mode, the signal input into channel 1 will be output from the bridged end, on other hand, the output
level control of channel 2 should be turn down to smallest.
14
Fan
The fan can accelerate the flow of air to lower the temperature inside unit. The inside temperature determines
the fan speed which controls the inside air flowing speed.
