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 bending 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 (although not
always achievable) to avoid ground loops is to connect the ground of all components to a central point (star
connection). The central point of a sound installation is the mixer.
In order to determine the cause of interference, connect the different sections of the mixer in the following
sequence to the other units. Only make the next connection once you have checked the sound of the actual one.
Outputs :
Amplifier and speakers (Master outputs)
Amplifier and monitor speakers (AUX outputs)
Effect units (AUX outputs ord effect in/outputs)
Inputs :
Instruments with line signal (keyboards, samplers, recorders, etc.)
Microphones (one after the other)
Electric products must not be put into household waste. Please bring them to a
recycling centre. Ask your local authorities or your dealer about the way to proceed.
