amplifier in series to the first unit to send the same signal into several amplifiers in order to increase the audio power.
2. Speaker outputs
Binding posts or XLR/Jack (minimum load 4 Ohms)
Note : To avoid damage to the speakers, 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.
3. Power supply
Mains
Installation and Operation
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.
Audio Connections
Prior to making any connections, switch off all units that you wish to interconnect. Only use high quality leads that are sui
-
table 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.
