External Control - Source Audio Vertigo Tremolo User Manual

Low Cut Filter
The Vertigo also includes a low cut filter (a.k.a. high pass filter) with an adjustable frequency. This
filter is very useful for cutting out low frequencies that do not contribute to the sound of the
instrument, as well as subsonic frequencies which cannot be heard at all. Bass players often use low
cut filters set very low (around 10 Hz to 30 Hz) to reduce speaker excursion and improve the clarity of
the bass. Guitarists often use low cut filters set somewhat higher (around 80 Hz) in order to give the
bass player additional room in the low end of the mix.

The Parametric EQ and the Low Cut filter are configurable using the Neuro Hub or USB Editor
software. By default, the parametric EQ is disabled (flat), and the Low Cut filter is set to 10 Hz.

External Control

The Control Input port opens up a wide array of external control options, allowing for direct control
over many of the Vertigo's built-in parameters. It can be used as an expression input or as a data port
for the Neuro Hub.
Expression Control
The Vertigo's effects parameters can be controlled directly by an expression pedal or Hot Hand
connected to the Control Input port.
Expression Pedal Input
The Dual Expression Pedal or Reflex Universal Expression Pedal, both from Source Audio, can be
directly connected to the Control Input using a 3.5 mm, TRRS cable.
