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, …

• This unit has NOT been designed for use in mobile applications,
such as: mobile discobars, mobile PA systems, Live bands, audio
rental systems, …
• Removable rack-ears
This amplifier is equipped with 2 stereo bus inputs with
passthrough. These bus inputs are ideal when you want to hear the
same audio signal in different output zones. For example: zones 1
to 4 use bus 1 input. Zones 5 to 7 use bus 2. Zone 8 is set to line
in and uses its own input signal. In this case, set the input selector
for zone 1 to 4 to bus 1, from zone 5 to 7 to bus 2 and zone 8 to
line in.
The trigger input is ideal when you want to switch on the power
amplifier automatically using an external AC or DC trigger signal
coming from your audio system. The amplifier will be switched on
as long as the trigger voltage is present. Alternatively, you can set
the power on mode switch to the audio trig position: the amp will
automatically switch on when a sufficiently strong audio signal
is present at the input. The input sensitivity for the audio trigger
function is 15 mV on all inputs. After a few minutes of silence, the
amplifier will automatically switch itself off.

1. Bus 1 unbalanced stereo input on RCA connector: This input
can be selected in any zone by setting switch “10” to the BUS
1 position.
2. Bus 2 unbalanced stereo input on RCA connector: This input
can be selected in any zone by setting switch “10” to the BUS
2 position.
3. Bus 1 unbalanced stereo pass through on RCA connector: the
audio signal applied to the BUS 1 input can be tapped here.
4. Bus 2 unbalanced stereo pass through on RCA connector: the
audio signal applied to the BUS 2 input can be tapped here.
Connections (only output zone 1 is explained. Zone 2 –
8 are identical)

5. Power on mode selector: power on: the amplifier is powered
on when the power switch at the front panel is switched to
the on position. In the Audio Trig position, the amplifier will be
switched on automatically when a strong audio signal is present
at the input. In the Ext Trigger position, you have to apply a
3-30 V AC or DC voltage at the jack input “6”. The power
switch on the front panel must be in the on position. In the off
position, the amplifier will always be off.
6. Trigger input jack: 3.2 mm monojack input for the 3-30 V AC
or DC trigger voltage. The trigger voltage will switch on the
amplifier when switch “5” is in the Ext Trigger position and the
front panel power switch is in the on position.
7. Ext Trigger output jack pass through (out) connector, 3.2 mm
mono minijack: the trigger voltage applied at connector “6” is
passed through via this connector.
8. Channel input gain setting. Adjust the input gain to the output
level of your source.
9. Amplifier mode selector: set to stereo for normal operation, set
to bridge for bridged mode. Load impedance in bridged mode
must be 8 ohms or higher.
10. Input selector for zone 1. Select Bus 1, Bus 2 or Line in.
11. Zone 1 stereo speaker outputs on euroblock. Minimum load
impedance is 4 ohms in stereo mode and 8 ohms in bridge
mode.
12. Line in: unbalanced stereo input on RCA connector. In bridge
mode: use left input only.
13. Mains inlet connector: connect the mains cable supplied with

14. Mains fuse: when the fuse blows, replace only with the same
type and fuse rating.
15. Mains voltage selector: set to 230 or 115VAC according to your
local mains voltage.
