The Motion Sound Pro-3X simulates a classic rotary sound using any keyboard or organ.
The Motion Sound Pro-3X is a rotary speaker amplifier that can be used with any organ or keyboard setup. It takes the audio signal coming from your keyboard and splits the signal at 800 Hz, sending the part above 800 Hz to a 45-watt amplifier, which then sends the signal through rotating horns. The signal below 800 Hz is sent through a low rotor simulator, from which it can be connected to its own amplifier. You get a classic rotary organ sound.
Instructions
1. Plug one end of the TRS cable into the "Output" jack on the keyboard, and plug the other end into the "Input" jack on the Pro-3X. Turn the volume on the keyboard about halfway up.
2. Connect the speed control pedal to the "Pedal" jack on the Pro-3X in the same manner as the above step.
3. Turn the "Volume" knob on the Pro-3X all the way down, and turn the rest of the controls to their halfway points, then turn on the Pro-3X.
4. Plug one end of a TRS cable into the "Sim Out" jack on the Pro-3X, and plug the other end into the "Input" jack on the low rotor amplifier.
5. Turn the "Volume" knob on the low rotor amplifier all the way down, then turn the low rotor amplifier on.
6. Turn the "Volume" knob on the Pro-3X to 3 or 4. Press some keys on your keyboard while turning the "Volume" knob on the low rotor amplifier up gradually to the desired level.
