Safety first!
• Caution! This professional device needs to be installed by
qualified personnel only.
• Please check the carton box for any kind of damage on
reception of the goods. In case of a damaged carton, please
contact your dealer before opening the carton.
• !!!! Danger !!!! Exposure to high sound levels may cause a
permanent hearing loss. Individuals vary considerably to sound
pressure level induced hearing loss but nearly everyone will
lose some hearing if exposed to high sound pressure levels for
a sufficient amount of time. Therefore it is recommended that
all persons exposed to equipment capable of producing high
sound pressure levels, such as this amplifier, be protected by
hearing protection while installing or operating this unit.
• Read all documentation before operating your equipment.
• Keep all documentation for future reference.
• Save the carton and packing material even if the equipment has
arrived in good condition.
• Should you ever need to ship the unit, use only the original
factory packing.
• Do not spill water or other liquids into or on the unit.
• Make sure power outlets conform to the power requirements
listed on the back of the unit.
• Do not use the unit if the electrical power cord is frayed or
broken.
• Always operate the unit with the AC ground wire connected to
the electrical system ground.

• Set level controls on amplifiers all the way down during power-
up to prevent speaker damage if there are high signal levels at
the inputs.
• Do not connect the inputs / outputs of amplifiers or consoles
to any other voltage source, such as a battery, mains source, or
power supply, regardless of whether the amplifier or console is
turned on or off.
• Power down & disconnect units from mains voltage before
making connections.
• Do not use the unit near stoves, heat registers, radiators, or
other heat producing devices.
• Do not operate equipment on a surface or in an environment
which may distort the normal flow of air around the unit. If the
unit is used in an extremely dusty or smoky environment, the
unit should be periodically “blown free” of dust.
• Do not remove the cover. Removing the cover will expose you
to potentially dangerous volt ages.
• Do not drive the inputs with a signal level higher than that
required to drive equipment to full output.
• Do not run the output of any amplifier back into another input.
• In case of mal-function this device should be serviced by
qualified service personnel only.
• This unit has NOT been designed for use in mobile applications,
such as: mobile discobars, mobile PA systems, Live bands, audio
rental systems, …

Operation
1. Removable rack ears for 19 rack mounting.
2. Power switch: after switching on the power, the power led will
light up after approx 1 second. The limit-muted leds will light
up for a few seconds to avoid excessive power on pop noise.
3. Power led
4. Channel 1 status led bar and mute switch: when the mute
switch is pressed, the orange “LIMIT – MUTED” led will light
up. This led will also light up when the internal limiter is
activated to avoid the amplifier from being overloaded by high
input signals. The “CLIP – OVERLOAD” led indicates that the
power amplifier is clipping: reduce the input signal at once
whenever this occurs !!! The green “SIGNAL - -40dB” led
will light up when an input signal is present. The red “INPUT
– OVERLOAD” indicates that the input is being overloaded.
Reduce the incoming signal at once !!! This led will blink
when temperature protect is active: in this case the amplifier
will automatically reduce the output power to avoid further
overheating.

!!! IMPORTANT !!!
This amplifier relies on convectional and active cooling. In normal
situations, overheating will not occur. The unit can be built in a 19
inch rack system, but it is forbidden to block the ventilation holes
provided. Therefore, it is absolutely necessary to allow at least
one free rack space or 44 mm above and beneath the amplifier.
Make sure the ambient temperature is between 0 and 40°C.
Operating the unit beyond its normal limits will result in excessive
internal temperature. Power amplifiers are hard workers, and
their behaviour is similar to human beings. In extreme conditions,
human beings are not able to perform efficiently. This also applies
to amplifiers. It is generally a bad idea to mount multiple heat
generating units such as amplifiers in the same rack. If necessary,
use an additional forced ventilation system in your mounting rack.
The mains fuse is located inside the unit. When the fuse is broken,
replace it with a fuse of the same current and voltage rating: 10
AT/250V. For qualified personnel only!
This unit has NOT been designed for use in mobile applications,
such as: mobile discobars and DJ setups, mobile PA systems, Live
bands, audio rental systems, …
Use it in fixed installations only.
