ENGLISH
 The power cord should always be in perfect condition: switch the unit immediately off
when the power cord is squashed or damaged.
 Never let the power-cord come into contact with other cables!
 When the power switch is in OFF position, this unit is not completely disconnected from
the mains!
 This appliance must be earthed to in order comply with safety regulations.
 In order to prevent electric shock, do not open the cover. Apart from the mains fuse there
are no user serviceable parts inside.
 Never repair a fuse or bypass the fuse holder. Always replace a damaged fuse with a
fuse of the same type and electrical specifications!
 In the event of serious operating problems, stop using the appliance and contact your
dealer immediately.
 Please use the original packing when the device is to be transported.
 Due to safety reasons it is prohibited to make unauthorized modifications to the unit.
INSTALLATION GUIDELINES:
 Install the unit in a well-ventilated location where it will not be exposed to high
temperatures or humidity.
 Placing and using the unit for long periods near heat-generating sources such as
amplifiers, spotlights, etc. will affect its performance and may even damage the unit.
 The unit can be mounted in 19-inch racks. Attach the unit using the 4 screw holes on the
front panel. Be sure to use screws of the appropriate size. (screws not provided)
Take care to minimize shocks and vibrations during transport.
 When installed in a booth or flight case, please make sure to have good ventilation to
improve heat evacuation of the unit.
 To avoid condensation to be formed inside, allow the unit to adapt to the surrounding
temperatures when bringing it into a warm room after transport. Condense sometimes
prevents the unit from working at full performance.
CLEANING THE UNIT:
Clean by wiping with a cloth slightly dipped with water. Avoid getting water inside the unit.
Do not use volatile liquids such as benzene or thinner which will damage the unit.
Clean the ventilation holes regularly with a vacuum cleaner. This increases the cooling
capacity of the amplifier fans and helps preventing temperature overheat.
CONNECTIONS
Be sure to turn off the unit before you make changes to the wiring. For the signal inputs we
recommend using the XLR-connections. Use good quality signal cables to ensure
excellent audio quality. For the speakers you must use the Speakon
description of the unit you will find more information on how to connect the amplifier.

FUNCTIONS
(FRONT)
1. VENTILLATION HOLES: during its operation the amplifier produces heat that needs to
be dissipated. The fans inside the amplifier must be able to evacuate the heat in the
most effective way. Therefore is it very important not to cover any of the ventilation
openings as this may result in overheating. Clean the ventilation holes regularly with a
vacuum cleaner. This increases the cooling capacity of the amplifier fans and helps
preventing temperature overheat.
2. GAIN CONTROLS: These potentiometers are used to control the input sensitivity of
the amplifier. Each channel has its own control.
You can use these controls to set the maximum sound level of your setup:
 Turn both controls on the amplifier to the left.
 Put on some music on and make sure the VU meters on your mixer are at 0dB.
(from time to time the red zone is lit)
 Set the Master output from your mixer to maximum.
 Open the Gain controls from the amplifier until the maximum desired sound level
is reached.
 Make sure nobody can reach the Gain controls of the amplifier.
You have just set the maximum level the DJ is able to produce. Your neighbors will be
glad... (in some cases the DJ is not )
Note: In Mono and Bridge mode, only the gain control of the left channel is used to adjust the input
sensitivity.
3. OPERATION MODE LEDS: These LEDs indicates the operation mode. Switch (12) on
the rear panel is used to choose one of these 3 possible modes:
 STEREO MODE: Both LEDs are lit. This is the most common mode, both
channels are working separately.
 MONO MODE: Only the LED of the right channel is lit. Basically this is identical to
stereo mode but the inputs of both channels are linked so the output will be mono.
In this case you only need to use the input of the left channel to drive both output
channels.
 BRIDGE MODE: Only the LED of the left channel is lit. Both channels are linked
in "bridge mode" to obtain a mono output with much higher power.
