PROFESSIONAL POWER AMPLIFIERS ADVANTAGE SERIES
CONNECTING TO THE MAINS
The connection of the power amplifier to the mains takes place by means of a three-wire cord
provided by the factory. The European standard colour code is: Brown-Live, Blue-Neutral and
Yellow/Green-Earth, keeps in mind this mains configuration, whenever handle the power amplifier
plug.
In the connection of several devices to the same AC distribution board and extension cables,
keeps in mind the maximum current of the power amplifier, and make sure that the mains
connector, as well as the AC distribution board, are of enough current capacity, since could take
place in the mains connector, and in the same AC distribution board a overheating, with the risk of
fire and/or short circuit. The following list shows the maximum average current requirement of the
different models of power amplifiers at normal music operation:
MODELS MAXIMUM CURRENT REQUIREMENT
A3.5
2A.
A7
4A.
A11
6A.
Make sure that the power amplifier power switch is at position 0 (turned off).
Insert the male connector of the three-wire cable into the mains plug.
Turn on the power amplifier power switch. Right now the power amplifier will turn on.
CAUTION: Make sure that the mains voltage is the correct, as well as their fuse is the adequate.
INPUT CONNECTION
Each power amplifier's channel incorporates one XLR-3-31 female connector. The inputs are
balanced, with a nominal impedance of 20 KΩ (10 KΩ unbalanced). The next list shows the input
pins correspondence as A.E.S recommendation practice:
