The sound of the "Rotary"
speaker is unmistakable, with its
classical DOPPLER effect,
obtained by the speakers rotating
in opposite directions on a
longitudinal axis.
The motors used for driving the
speakers are electronically
controlled.
Rotary uses the 40 WATT
RMS valve amplifier "Back
Stage".
“Back stage” is the complete
amplification system for the
PARI.E organ.
It is composed of the valve
amplifier and the
Rotary speaker.
It is the ideal system for
stage use and general
live performances.
