3. [INPUT] connector.
Unbalanced jack connector for connecting only the audio signal of the instrument to be amplified.
N.B.
The speed control / stop of the speakers can be done with a foot switch connected to the [FOOT SWITCH] connector
(see point 10) or via MIDI (see point 11).
4. [HORN STOP] button.
Horn section stop position selection button:
- REAR: towards the rear side of rotary speaker.
- RAND: random position.
5. [HORN SPEED] button.
Button to increase or decrease the rotation speed (both Slow and Fast) of the Horn section:
- +5: 5% increase
- -5: 5% decrease
6. [ROTOR STOP] button.
Button to stop the rotation of the Drum section only, so as to use the Vortex 315 in "Memphis Style" mode
so that only the upper rotor continues to spin. This mode allows you to have a solid bass sound and the
treble that continue to be modulated.

- ON: Rotating Drum
7. EQUALIZER section.
This section includes controls for the semi-parametric equalizer that Vortex 315 is equipped with.
- [LOW] potentiometer: allows to adjust the attenuation (from 0 to -12 dB) or the amplification (from 0 to
+12 dB) of the low frequencies (lower than 200 Hz).
- [MID FREQ] potentiometer: allows to select the central frequency of intervention that is attenuated or
enhanced by the [MID GAIN] potentiometer. As reported in screen printing, the range of selectable
frequencies is 200 Hz – 2 KHz.
- [MID GAIN] potentiometer: allows to adjust the attenuation (from 0 to -12 dB) or the exaltation (from 0
to +12 dB) of the signals around the frequency adjusted with the potentiometer [MID FREQ].
- [HIGH] potentiometer: allows to adjust the attenuation (from 0 to -12) or the exaltation (from 0 to +12)
of high frequencies (above 2 KHz).
8. [VOLUME] potentiometer: allows to adjust the output volume to the amplifier. Turning the knob to "0" the
signal is completely silent.
9. [PRESET] selector: selection knob of one of the 6 Presets. The Legend Rotary Editor allows the
adjustment and storage in real time of the operating parameters for the Presets 3 – 4 – 5 – 6 (1 – 2 are not
editable). Rotation speeds, transition times, relative levels and much more can be modified by the users
according to their needs and stored in the Vortex 315 Presets.
10. [FOOT SWITCH] connector: connect here the cable from the pedal you wish to use to control the speed of
the rotating speakers. Use with:
- single switch type pedal: the Slow / Fast speeds are selected by shortly pressing the pedal, while
keeping it pressed stops the rotation (Brake).
- double switch pedal: one switch assumes the Brake / Go function, the other switch assumes the Slow /
Fast speed selection function.
N.B.
It is necessary to select the type of pedal used in the Legend Rotary Editor application. In default conditions the use
of a single switch pedal is assumed.
11. [MIDI IN] connector: MIDI connector for connecting the instrument for speed and stop selection via MIDI
messages. In the default condition, the following Control Changes are received (in any channel):
- CC66=0: Slow speed
- CC66=127: Fast speed
- CC67=0: Brake off
- CC67=127: Brake on
