PROFESSIONAL POWER AMPLIFIERS ADVANTAGE SERIES
7. DISTRIBUTED SYSTEMS APPLICATION (PUBLIC ADDRESS)
Currently, the standard of public address PA, uses loudspeakers of 70.7 Volts and 100 Volts
with different powers. The professional power amplifiers ADVANTAGE series could work with these
public address systems. In order to use the power amplifiers in distributed systems, it is necessary to
choose the loudspeaker voltage operation (and therefore the power amplifier model) and wire the
loudspeakers in parallel and then to the power amplifier output, always keeping in mind that the sum
of the loudspeaker power placed in parallel with the power amplifier output should not never
overcome the maximum acceptable power of the amplifier. The next table shows the voltages and
powers to choose from.
Note that both configurations are in Bridge mode so, never refer any loudspeaker to ground in
the sound system installation.
