External Expression Controller (1/8”/3.5mm TRRS Connection – CONTROL INPUT jack)
The Source Audio Dual Expression Pedal or Reflex Universal Expression Pedal can be directly
connected to the CONTROL INPUT jack using a 3.5mm (1/8 inch), TRRS cable. In the case of an
expression pedal with a TRRS plug, the tip connection is power, the first ring is the X-axis expression
signal, the second ring is the Y-axis expression signal, and the sleeve connection is ground. In this
configuration, the Ventris uses the X expression signal as its expression source.
Third party expression pedals can be connected to the CONTROL INPUT as well, as long as they have a
3.5 mm (1/8”) TRS (Tip Ring Sleeve) plug with power on the tip, expression (the wiper of the
potentiometer) on the ring, and ground on the sleeve, as seen in the diagram below.
Expression pedals with TS (Tip Sleeve) plugs will not work correctly with the CONTROL INPUT of the
Ventris. For proper operation, the configuration steps in the next section must be followed when
using any expression pedal, whether from a third party or from Source Audio.
Configuring the Expression Pedal
When the expression pedal is connected to the Ventris, follow these simple steps to calibrate it and
map it to control different effect parameters.
1. Press the CONTROL INPUT BUTTON to enable external control mode. The CONTROL LED should be
lit red.
2. Press and hold the CONTROL INPUT BUTTON until the CONTROL LED begins to blink slowly
(approximately one blink per second).
3. Move the expression pedal over the range of motion you would like to use to control the
Ventris. If you would like to use the expression pedal’s full range of motion, make sure to
move the pedal all the way from its minimum position to its maximum position. Note that
