PRO-3T POWERED
ROTARY HORN UNIT
“Based
on the Characteristic Sound of the Leslie
147”
The
Motion Sound PRO-3T Rotary Horn Unit is an
improved version of the very successful PRO-3 and
is a perfect choice for bands or other players
with limited space. Both the PRO-3 and the PRO-3T
were designed to deliver the classic Leslie Model
147 sound without having to carry a full size
Leslie. The PRO-3T is a powered
“horn-only” unit which is compact and
ruggedly built. It features a true motorized
revolving “horn” for high frequencies,
and a crossover and rotor simulator for bass
frequencies below 800 hz. These lower frequencies
are directed to 1/4″ stereo output jacks for
use with a separate bass amp and speakers or
Public Address (PA) system. The PRO-3 is designed
to be used where space is very limited, but the
classic rotary horn sound is desirable.
No electronic simulator or other device can
capture the true rotary horn sound of the 147,
122 or other classic models. Only a true Leslie
or the Motion Sound PRO-3T or R3-147 can
accomplish what professional musicians demand
most – “The Real Deal” in classic
sound.
Enhanced
with a Real 12AX7 Vacuum Tube Preamp for Warmth!
The PRO-3T has a 12AX7 vacuum tube in the
preamp for true “tube warmth” and dial
in front panel pre and post gain controls to
allow the user accurate distortion control from
slight distortion to a 70’s tube crunch
completely overdriven sound. A built-in Contour
(tone) Control allows the user to alter the
PRO-3T sound from a bright solid-state amp sound
or the mellower 147 sound.
Technical
Information
The PRO-3T is equipped with a 40-watt RMS
power amplifier for the rotating horn, and an 18
db / octave crossover that is designed to cross
over at 800 hz , with frequencies 800 hz and
above directed to the rotating horn, and
frequencies below 800 hz directed to the rotor
simulator and out to the 1/4″ outputs. The
PRO-3T was designed to be easily docked with a
Motion Sound Low-Pro Model LP-120 lower rotor
system which features an actual mechanical
rotating drum and a 120 watt amplifier and 150
watt 12″ speaker or it can be used with
another very-good quality bass amp and speakers.
If a separate amp and speakers are used, the bass
WILL have the rotary effect of a Leslie
bass-rotor due to the rotor simulator in the
PRO-3T.
A 1/4″ foot switch is supplied with the
PRO-3T to control motor speed switching which
controls both the upper horn unit speed-change
and the bass rotor simulator speed-change
simultaneously. An enhanced lower rotor simulator
with a front panel AM modulation control allows
the user to tweak the bass rotor sound to suit
the situation and equipment. The PRO-3T includes
a special output connector to allow easy docking
with the Low-Pro rotating drum system.
