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.
Instruction manualREVAMP4240T 5
• 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, …
• Before using the amplifier for the first time, check the
impedance of your 100 volt speaker lines using the Apart
IMPMET.

• Euroblock speaker connectors with multiple taps: 35 volt, 50
volt, 70 volt, 100 volt and 4 ohm
• Extended speaker and amp protection circuits: over current
protect, over temperature protect
• Versatile LED status indicators

Note: the integrated APC limiter will automatically limit the
incoming audio signal to avoid overloads. This feature can not be
defeated and acts as a lifesaver for your valuable speakers.

1. Channel 2 overload led: when this led lights up, you are
overloading the input. Lower the input signal immediately to
prevent the amplifier from shutting down.
2. Channel 2 unbalanced input and link cinch connector: connect
the line level input signal for channel 2 here. Line level is 0 dBV.
Input and link connector are internally connected 1 on 1.
3. Channel 1 overload led: when this led lights up, you are
overloading the input. Lower the input signal immediately to
prevent the amplifier from shutting down.
Connections
Only channel 1 and 2 are explained. Channel 3 and 4 are functionally
identical to 1 and 2.

4. Channel 1 unbalanced input and link cinch connector: connect
the line level input signal for channel 1 here. Line level is 0 dBV.
Input and link connector are internally connected 1 on 1. This
connector is also used in bridge mode.
5. Channel 2 input gain setting. Adjust the input gain to the
output level of your source. Make sure to avoid the clip led
lighting up at the strongest input peak level.
6. Channel 2 balanced input on 3 pole euroblock connector.
7. Channel 1 input gain setting. Adjust the input gain to the
output level of your source. Make sure to avoid the clip led
lighting up at the strongest input peak level.
8. Channel 1 balanced input on 3 pole euroblock connector. This
connector is used in bridge mode.
9. HPF on/off dipswitch for channels 1 and 2: set to on position to
enable the 250Hz highpass filter (ideal for using 100 volt horn
speakers)
10. Channel 2 output on euroblock: use the com (negative) in
combination with one of the output options: low impedance (4
ohms), 35 volt, 50 volt, 70 volt or 100 volt (positive). Never use
more than one output simultaneously.
11. Bridge button: set to 2 channel for normal operation. Set to
bridge mode for bridge mode operation.
12. Channel 1 output on euroblock: use the com (negative) in
combination with one of the output options: low impedance (4
ohms), 35 volt, 50 volt, 70 volt or 100 volt (positive). Never use
more than one output simultaneously.
13. Fan area: keep free from dust and obstructions.
