If you are not sure about the correct connection or if questions arise which are not answered by the operating
instructions, please do not hesitate to contact support or a specialist of your choice. Consult a specialist if
you are in doubt the operating principle or the safety of the product.
FRONT PANEL CONTROLS :
1.
On/Off switch with Power LED
2. Gain Control: Allows to attenuate the input signal level and the output volume of the amplifier.
3.
LED Vumeter: Shows the master output level.
REAR CONNECTIONS
1.
Line input
Connect the master output of your mixer or audio source to the 6.35mm or RCA input (XLR on the AMP2000-
MKII) of the amplifier.
2.
Speaker outputs
Speaker outputs via screw terminals or Turnlock connectors. Please note: Do not use both connectors at the
same time! Use only speaker with a minimum impedance of 4 ohms.
Note : To avoid damage to the speakers and/or the amplifier, only use speakers that have the same impedance
and power rating as the amplifier. Only use speaker cables and never signal cables as those used for micro
-
phones, music instruments and audio equipment in general.

INSTALLATION
Electrical Connections
Prior to connecting the amplifier on a wall outlet, check following points
•
The mains outlet must be earthed and comply with the safety regulations. If in doubt, ask and electrician.
•
The mains voltage must correspond to the supply voltage indicated on the rear panel (+/-10%)
•
The On /Off switch must be in OFF position
•
The amplifier must be switched off prior to unplugging the mains lead.
Power On/Off
Always switch on the amplifier at last and switch it off at first in your audio installation. Set all controls to the
minimum in order to avoid unpleasant and even dangerous noise.
Installation and Operation
Your amplifier is a high power unit that must be installed at a well ventilated place far from heat, humidity,
shocks and dust to avoid malfunction, defaults, electrical shocks and the risk of fire. The cooling air enters via
the front panel and leaves via the rear panel. The good ventilation is therefore of paramount importance. If you
install the amplifier in an equipment rack or a flight case, make sure not to obstruct the air flow. Never install
the amplifier in a closed rack or flight case as a part of the heat is evacuated by the metal ground plate. It is
recommended to leave at least one free space below the amplifier.
Audio Connections
Prior to making any connections, switch off all units that you wish to interconnect. Only use high quality leads
that are suitable for this application. Handle the cables with care and check the air flow regularly. Only pull the
plugs, never the cable. Do not use force to unplug a lead. Always roll the cables without making knots or ben-
ding them in order to ensure a long lifetime, proper operation and optimal performance.
Prevention and Detection of Interference
•
Make sure to install the amplifier in a place far away from industrial and high frequency radiations. Avoid to
install the amplifier near a radio, TV or mobile phone. These equipments are sources of interference.
•
When you connect the other components of your installation, avoid the constitution of ground loops that are
detrimental to the excellent sound qualities of the amplifier and potentially dangerous. He best way (al
