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)
