CONSTANT VOLTAGE VS 8-OHM SPEAKER SYSTEMS
A constant voltage speaker system differs from a traditional 8-ohm speaker system in
that it uses a step-up transformer at the audio source to raise the voltage and lower the
current on the transmission line. At the speaker end, a step-down transformer converts
the signal back to a normal speaker level voltage. This reduces power loss during
transmission, which allows for the use of longer speaker wire runs using smaller gauge
wire.
Additionally, a constant voltage speaker system allows for the use of multiple speakers
on each channel, without the need for complicated impedance calculations and
configurations. In a constant voltage system, all speakers on a given channel are
connected in parallel and the complicated impedance calculations are replaced by
simple wattage calculations.
